• 基于 SSH 框架的 Criteria 和 DetachedCriteria 多条件查询

    Hibernate 定义了 CriteriaSpecification 接口规范用来完成面向对象的条件查询，Criteria 和 DetachedCriteria 就是 CriteriaSpecification 的子接口。

    在进行本篇的内容之前，我们先来大致说一说 Criteria 和 DetachedCriteria 的主要区别：

    Criteria 和 DetachedCriteria 的创建的形式不一样， Criteria 是在线的，所以它是由 Hibernate Session 进行创建的；而 DetachedCriteria 是离线的，创建时无需 Session。

    本篇完整实现如下：

    一、导 jar 包

      1 antlr-2.7.6.jar
  2 asm-commons-3.3.jar
  3 commons-collections-3.1.jar
  4 commons-fileupload-1.3.jar
  5 commons-io-2.0.1.jar
  6 commons-lang3-3.1.jar
  7 commons-logging-1.1.3.jar
  8 dom4j-1.6.1.jar
  9 freemarker-2.3.19.jar
 10 hibernate3.jar
 11 hibernate-jpa-2.0-api-1.0.1.Final.jar
 12 javassist-3.12.0.GA.jar
 13 jta-1.1.jar
 14 mysql-connector-java-5.0.8-bin.jar
 15 ognl-3.0.6.jar
 16 slf4j-api-1.6.1.jar
 17 spring-beans-4.3.8.RELEASE.jar
 18 spring-context-4.3.8.RELEASE.jar
 19 spring-core-4.3.8.RELEASE.jar
 20 spring-expression-4.3.8.RELEASE.jar
 21 spring-jdbc-4.3.8.RELEASE.jar
 22 spring-orm-4.3.8.RELEASE.jar
 23 spring-tx-4.3.8.RELEASE.jar
 24 spring-web-4.3.8.RELEASE.jar
 25 struts2-core-2.3.15.3.jar
 26 struts2-spring-plugin-2.3.15.3.jar
 27 xwork-core-2.3.15.3.jar

    二、配置 Struts2 核心过滤器 (web.xml)

      1 <filter>
  2     <filter-name>struts2</filter-name>
  3     <filter-class>
  4          org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
  5     </filter-class>
  6 </filter>
  7 
  8 <filter-mapping>
  9     <filter-name>struts2</filter-name>
 10     <url-pattern>/*</url-pattern>
 11 </filter-mapping>

     三、Jsp 表单查询页 (list.jsp)

      1 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
  2 <%@ taglib uri="/struts-tags" prefix="s" %>
  3 <%
  4 String path = request.getContextPath();
  5 String basePath = request.getScheme()+"://"+request.getServerName()
  6    +":"+request.getServerPort()+path+"/";
  7 %>
  8 
  9 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
 10 <html>
 11   <head>
 12     <base href="<%=basePath%>">
 13 
 14     <title>My JSP 'index.jsp' starting page</title>
 15 	<meta http-equiv="pragma" content="no-cache">
 16 	<meta http-equiv="cache-control" content="no-cache">
 17 	<meta http-equiv="expires" content="0">

 19 	<meta http-equiv="description" content="This is my page">
 20 	<!--
 21 	<link rel="stylesheet" type="text/css" href="styles.css">
 22 	-->
 23   </head>
 24 
 25 <body>
 26 <form action="${pageContext.request.contextPath}/queryCourseByCondition.action"
 27         method="post">
 28 	<table width="88%" border="0" class="emp_table" style="80%;">
 29 
 30 	  <tr>
 31 	       <td width="20%">姓名：</td>
 32 	       <td><input type="text" name="userName" size="30" value="" /></td>
 33 	  </tr>
 34 
 35 	  <tr>
 36 	       <td >性别：</td>
 37 	       <td > <select name="gender" id="sex">
 38 			<option value="">--选择性别--</option>
 39 			<option value="男">男</option>
 40 			<option value="女">女</option>
 41 	             </select>
 42 	       </td>
 43 	  </tr>
 44 
 45 	  <tr>
 46 	       <td >年龄：</td>
 47 	       <td ><input type="text" name="ageStart" size="10" value="" />  至  <input
 48                   type="text" name="ageEnd" size="10" value="" /></td>
 49 	  </tr>
 50 
 51 	  <tr>
 52 	       <td>是否上传简历：</td>
 53 	       <td ><select name="isUpload" id="isUpload">
 54 			<option value="">--请选择--</option>
 55 			<option value="1">有</option>
 56 			<option value="2">无</option>
 57 	           </select>
 58 	       </td>
 59 	  </tr>
 60 
 61 	  <tr>
 62 	       <td>信息备注：</td>
 63 	       <td><input type="text" name="remark" size="30" value="" /></td>
 64 	  </tr>
 65 
 66 	</table><br>
 67 	<input type="submit" value="查询"/>
 68 	<hr>
 69   <table width="97%" border="1" >
 70 
 71   <tr class="henglan" style="font-weight:bold;">
 72     <td width="14%" align="center">姓名</td>
 73     <td width="13%" align="center">性别</td>
 74     <td width="13%" align="center">年龄</td>
 75     <td width="18%" align="center">简历</td>
 76     <td width="20%" align="center">备注</td>
 77   </tr>
 78 
 79       <%--数据展示 --%>
 80       <s:iterator>
 81          <tr class="tabtd1">
 82 	       <td align="center"><s:property value="userName"/> </td>
 83 	       <td align="center"><s:property value="gender"/></td>
 84 	       <td align="center"><s:property value="age"/></td>
 85 	       <td align="center"><s:property value="fileName"/></td>
 86 	       <td align="center"><s:property value="remark"/></td>
 87 	   </tr>
 88      </s:iterator>
 89    </table>
 90   </form>
 91  </body>
 92 </html>

     四、封装 UserBean (User.java)

      1 package com.fhcq.bean;
  2 
  3 import java.io.Serializable;
  4 
  5 public class User implements Serializable {
  6 
  7 	private Integer userID;
  8 	private String userName;
  9 	private String gender;
 10 	private Integer age;
 11 	private String fileName;
 12 	private String remark;
 13 
 14 	public Integer getUserID() {
 15 		return userID;
 16 	}
 17 	public void setUserID(Integer userID) {
 18 		this.userID = userID;
 19 	}
 20 	public String getUserName() {
 21 		return userName;
 22 	}
 23 	public void setUserName(String userName) {
 24 		this.userName = userName;
 25 	}
 26 	public String getGender() {
 27 		return gender;
 28 	}
 29 	public void setGender(String gender) {
 30 		this.gender = gender;
 31 	}
 32 	public Integer getAge() {
 33 		return age;
 34 	}
 35 	public void setAge(Integer age) {
 36 		this.age = age;
 37 	}
 38 	public String getFileName() {
 39 		return fileName;
 40 	}
 41 	public void setFileName(String fileName) {
 42 		this.fileName = fileName;
 43 	}
 44 	public String getRemark() {
 45 		return remark;
 46 	}
 47 	public void setRemark(String remark) {
 48 		this.remark = remark;
 49 	}
 50 
 51 }

     五、配置数据库表生成策略 (User.hbm.xml)

      1 <?xml version="1.0" encoding="UTF-8"?>
  2 <!DOCTYPE hibernate-mapping PUBLIC
  3     "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
  4     "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
  5 <hibernate-mapping package="com.fhcq.bean">
  6 
  7     <!-- name是类名  如果有包就不用写全类名，否则要写。  table 表示对应的表名 。建议都要写  -->
  8     <class name="User" table="user">
  9 
 10            <!--使用Id配置主键 必须配置  -->
 11            <id name="userID" column="userID">
 12                   <!--目前照常，主键生成策略  -->
 13                   <generator class="native"></generator>
 14            </id>
 15 
 16           <property name="userName"  column="userName"></property>
 17           <property name="gender"  column="gender"></property>
 18           <property name="age"  column="age"></property>
 19           <property name="filename"  column="filename"></property>
 20           <property name="remark"  column="remark"></property>
 21 
 22     </class>
 23 </hibernate-mapping>

     六、设置数据库连接参数 (hibernate.cfg.xml)

      1 <!DOCTYPE hibernate-configuration PUBLIC
  2 	"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
  3 	"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
  4 
  5 <hibernate-configuration>
  6      <session-factory name="foo">
  7 
  8 	    <!-- 配置数据库驱动 -->
  9 	    <property name="hibernate.connection.driver_class">
 10 		com.mysql.jdbc.Driver
 11 	    </property>
 12 	    <!-- 要连接数控的用户名  -->
 13 	    <property name="hibernate.connection.username">root</property>
 14 	    <!-- 密码 -->
 15 	    <property name="hibernate.connection.password">123456</property>
 16 	    <!-- 连接数据库的路径 那个服务器 那个数据库  -->
 17 	    <property name="hibernate.connection.url">
 18 		jdbc:mysql://localhost:3306/usermanager
 19 	    </property>
 20 
 21 	    <!-- 操作的时候显示操做过程中的sql语句  -->
 22 	    <property name="show_sql">true</property>
 23 	    <!-- 格式化它要显示的sql语句 -->
 24 	    <property name="format_sql">true</property>
 25 	    <!-- 是否要自动创建表  -->
 26 	    <property name="hbm2ddl.auto">update</property>
 27 	    <!-- 事务自动提交  -->
 28 	    <property name="connection.autocommit">true</property>
 29 
 30 	    <!-- 优化选项 -->
 31 	    <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
 32 	    <!-- 导入映射文件 -->
 33 	    <mapping resource="com/fhcq/bean/User.hbm.xml" />
 34 
 35      </session-factory>
 36 </hibernate-configuration>

     七、配置 Struts (struts.xml)

      1 <?xml version="1.0" encoding="UTF-8" ?>
  2 <!DOCTYPE struts PUBLIC
  3 	"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
  4 	"http://struts.apache.org/dtds/struts-2.3.dtd">
  5 
  6 <struts>
  7 
  8    <!--修改struct2称为开发模式，修改配置之后会自动加载  -->
  9    <constant name="struts.devMode" value="true"></constant>
 10 
 11       <package name="package1" extends="struts-default">
 12 	   <!-- 多条件查询 -->
 13 	   <action name="queryCourseByCondition"
 14                 class="com.fhcq.action.QueryUserByConditionAction"
 15                       method="queryCourseByCondition">
 16 		 <result name="success">/index.jsp</result>
 17 	   </action>
 18       </package>
 19 
 20 </struts>

     八、表示层

    8.1、QueryUserByConditionAction 

      1 package com.fhcq.action;
  2 
  3 import java.util.List;
  4 
  5 import com.fhcq.bean.User;
  6 import com.fhcq.service.IUserService;
  7 import com.fhcq.service.UserServiceImpl;
  8 import com.opensymphony.xwork2.ActionContext;
  9 import com.opensymphony.xwork2.ActionSupport;
 10 import com.opensymphony.xwork2.ModelDriven;
 11 import com.opensymphony.xwork2.util.ValueStack;
 12 
 13 public class QueryUserByConditionAction extends ActionSupport implements
 14      ModelDriven<User>{
 15 
 16 	User user= new User();
 17 	private String ageStart;
 18 	private String ageEnd;
 19 	private String isUpload;
 20 	IUserService service;
 21 
 22 	public String queryCourseByCondition(){
 23 
 24 		String userName = user.getUserName();
 25 		String gender = user.getGender();
 26 		String remark = user.getRemark();
 27 
 28 		List<User> userlist = service.queryUserByCondition
 29                       (userName,gender,ageStart,ageEnd,isUpload,remark);
 30 		System.out.println("QueryUserByConditionAction queryUser() userlist= 
 31                       "+userlist);
 32 
 33 		ActionContext context = ActionContext.getContext();
 34 		ValueStack valueStack = context.getValueStack();
 35 		valueStack.push(userlist);
 36 
 37 		return SUCCESS;
 38 	}
 39 
 40 	@Override
 41 	public User getModel() {
 42 		// TODO Auto-generated method stub
 43 		return user;
 44 	}
 45 
 46 	public User getUser() {
 47 		return user;
 48 	}
 49 
 50 	public void setUser(User user) {
 51 		this.user = user;
 52 	}
 53 
 54 	public String getIsUpload() {
 55 		return isUpload;
 56 	}
 57 
 58 	public void setIsUpload(String isUpload) {
 59 		this.isUpload = isUpload;
 60 	}
 61 
 62 	public String getAgeStart() {
 63 		return ageStart;
 64 	}
 65 
 66 	public void setAgeStart(String ageStart) {
 67 		this.ageStart = ageStart;
 68 	}
 69 
 70 	public String getAgeEnd() {
 71 		return ageEnd;
 72 	}
 73 
 74 	public void setAgeEnd(String ageEnd) {
 75 		this.ageEnd = ageEnd;
 76 	}
 77 
 78 	public IUserService getService() {
 79 		return service;
 80 	}
 81 
 82 	public void setService(IUserService service) {
 83 		this.service = service;
 84 	}
 85 
 86 }

     九、业务层

    9.1、QueryUserService

      1 package com.fhcq.service;
  2 
  3 import java.util.List;
  4 
  5 import com.fhcq.bean.User;
  6 
  7 public interface IUserService {
  8 
  9  	List<User> queryUserByCondition(String userName, String gender,String ageStart,
 10                 String ageEnd, String isUpload,String remark);
 11 }

     9.2、QueryUserServiceImpl

      1 package com.fhcq.service;
  2 
  3 import java.util.List;
  4 
  5 import com.fhcq.bean.User;
  6 import com.fhcq.dao.IUserDao;
  7 import com.fhcq.dao.UserDaoImpl;
  8 
  9 public class UserServiceImpl implements IUserService{
 10 
 11 	IUserDao dao;
 12 
 13 	@Override
 14 	public List<User> queryUserByCondition(String userName, String gender,
 15                String ageStart, String ageEnd, String isUpload,String remark) {
 16 		// TODO Auto-generated method stub
 17 		List<User> queryUserByCondition = dao.queryUserByCondition
 18                      (userName,gender,ageStart,ageEnd,isUpload,remark);
 19 		return queryUserByCondition;
 20 	}
 21 
 22 	public IUserDao getDao() {
 23 		return dao;
 24 	}
 25 
 26 	public void setDao(IUserDao dao) {
 27 		this.dao = dao;
 28 	}
 29 
 30 }

    十、数据持久化层

    10.1、QueryUserDao

      1 package com.fhcq.dao;
  2 
  3 import java.util.List;
  4 
  5 import com.fhcq.bean.User;
  6 
  7 public interface IUserDao {
  8 
  9 	List<User> queryUserByCondition(String userName, String gender, String ageStart,
 10               String ageEnd, String isUpload, String remark);
 11 
 12 }

    Criteria 在线实现多条件查询：

    10.2、配置 Spring (applicationContext.xml)

      1 <?xml version="1.0" encoding="UTF-8"?>
  2 <beans xmlns="http://www.springframework.org/schema/beans"
  3        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4        xsi:schemaLocation="
  5 	   http://www.springframework.org/schema/beans
  6 	   http://www.springframework.org/schema/beans/spring-beans.xsd">
  7 
  8  	<bean id="myUserDaoImpl" class="com.fhcq.dao.UserDaoImpl"></bean>
  9 
 10 	<bean id="service" class="com.fhcq.service.UserServiceImpl" >
 11 		<property name="dao" ref="myUserDaoImpl"></property>
 12 	</bean>
 13 
 14  </beans>

    10.3、HibernateUtils 方法封装 

      1 package com.fhcq.utils;
  2 
  3 import org.hibernate.Session;
  4 import org.hibernate.SessionFactory;
  5 import org.hibernate.cfg.Configuration;
  6 
  7 public class HibernateUtils {
  8 
  9 	static SessionFactory sessionFactory;
 10 	static {
 11 		Configuration configure = new Configuration().configure();
 12 		sessionFactory = configure.buildSessionFactory();
 13 		//增加 关闭虚拟机的时候自动释放
 14 		Runtime.getRuntime().addShutdownHook(new Thread(new Runnable(){
 15 			@Override
 16 			public void run() {
 17 				// TODO Auto-generated method stub
 18 			System.out.println("当运行结束的时候执行！");
 19 			sessionFactory.close();
 20 			}
 21 		}));
 22 	}
 23 
 24 	public static Session getSession(){
 25 		Session openSession = sessionFactory.openSession();
 26 		return openSession;
 27 	}
 28 
 29 	public static Session getCurrentSession(){
 30 		Session openSession = sessionFactory.getCurrentSession();
 31 		return openSession;
 32 	}
 33 }

    10.4、QueryUserDaoImpl

      1 package com.fhcq.dao;
  2 
  3 import java.util.List;
  4 
  5 import org.apache.commons.lang3.StringUtils;
  6 import org.hibernate.Criteria;
  7 import org.hibernate.Query;
  8 import org.hibernate.Session;
  9 import org.hibernate.SessionFactory;
 10 import org.hibernate.cfg.Configuration;
 11 import org.hibernate.criterion.Restrictions;
 12 import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
 13 
 14 import com.fhcq.bean.User;
 15 import com.fhcq.utils.HibernateUtils;
 16 
 17 public class UserDaoImpl implements IUserDao{
 18 
 19 	@Override
 20 	public List<User> queryUserByCondition(String userName, String gender,
 21                  String ageStart, String ageEnd, String isUpload, String remark) {
 22 		// TODO Auto-generated method stub
 23 
 24 		//如果查询页所有条件都没未填选的话，点击查询按钮则查询所有用户
 25 	    if(StringUtils.isBlank(userName) && StringUtils.isBlank(gender) &&
 26                   StringUtils.isBlank(ageStart) && StringUtils.isBlank(ageEnd)  &&
 27                   StringUtils.isBlank(isUpload) && StringUtils.isBlank(remark)){
 28 
 29 		  Session session = HibernateUtils.getSession();
 30 		  session.beginTransaction();
 31 		  //-----------------------------	
 32 		  Query createQuery = session.createQuery("from User");
 33 		  List<User> userlist = createQuery.list();
 34 		  //------------------------------
 35 		  session.getTransaction().commit();
 36 		  session.close();
 37 		  return userlist;
 38 
 39 	      }else{
 40 
 41             Configuration configure = new Configuration().configure();
 42 	          SessionFactory  sessionFactory = configure.buildSessionFactory();
 43 	          Session openSession = sessionFactory.openSession();
 44 		  //------------------------------
 45 
 46 		  Criteria createCriteria = openSession.createCriteria(User.class);
 47 
 48 		  if(StringUtils.isNotBlank(userName)){
 49 			createCriteria.add(Restrictions.like("userName", userName.replace
 50                               ("", "")));
 51  		  }
 52 		  if(StringUtils.isNotBlank(gender)){
 53 			createCriteria.add(Restrictions.eq("gender", gender));
 54  		  }
 55 		  if(StringUtils.isNotBlank(ageStart)){
 56 		        Integer ageStart1 =Integer.parseInt(ageStart);
 57 			createCriteria.add(Restrictions.ge("age", ageStart1));
 58 		  }
 59 		  if(StringUtils.isNotBlank(ageEnd)){
 60 			Integer ageEnd1 =Integer.parseInt(ageEnd);
 61 			createCriteria.add(Restrictions.le("age", ageEnd1));
 62 		  }
 63 		  if(StringUtils.isNotBlank(isUpload)){
 64 
 65 			 if("1".equals(isUpload)){
 66 
 67 			       createCriteria.add(Restrictions.isNotNull("fileName"));
 68 
 69                          }else{
 70 
 71 			        createCriteria.add(Restrictions.isNull("fileName"));
 72 			 }
 73 
 74 		  }
 75 		  if(StringUtils.isNotBlank(remark)){
 76 			       createCriteria.add(Restrictions.like("remark",
 77                                       remark.replace("", "")));
 78 	 	  }
 79 
 80 		  List userlist = createCriteria.list();
 81 
 82 	         //------------------------------

 84 		  sessionFactory.close();

    DetachedCriteria 离线实现多条件查询：

    10.2、配置 Spring (applicationContext.xml)

      1 <?xml version="1.0" encoding="UTF-8"?>
  2 <beans xmlns="http://www.springframework.org/schema/beans"
  3        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4        xsi:schemaLocation="
  5 	   http://www.springframework.org/schema/beans
  6 	   http://www.springframework.org/schema/beans/spring-beans.xsd">
  7 
  8  	<bean id="mysessionFactory"
  9                       class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
 10 		 <!-- hibernate.cfg.xml 告诉springHibernate的配置文件在哪 -->
 11 	  	 <property name="configLocation" value="classpath:hibernate.cfg.xml">
 12                </property>
 13 	</bean>
 14 
 15   	<bean id="myHibernateTemplate"
 16                      class="org.springframework.orm.hibernate3.HibernateTemplate">
 17   		<property name="sessionFactory" ref="mysessionFactory"></property>
 18   	</bean>
 19 
 20  	<bean id="myuserDaoImpl" class="com.fhcq.dao.UserDaoImpl">
 21  	        <property name="hibernateTemplate" ref="myHibernateTemplate"></property>
 22  	</bean>
 23 
 24 	<bean id="service" class="com.fhcq.service.UserServiceImpl" >
 25 		<property name="dao" ref="myuserDaoImpl"></property>
 26 	</bean>
 27 
 28 </beans>

    10.3、QueryUserDaoImpl

 34                                       ("", ""), MatchMode.ANYWHERE));
