为了之后学习的日子里加深对框架的理解和使用，这里将搭建步奏简单写一下，目的主要是方便以后自己回来脑补；
1:File--->New--->Other--->Maven--->Maven Project--->Next（之后界面如下所示：）
--->Next（点击next之后出现如下界面：选择最后一个 maven-archetype-webapp,然后点击next）
--->Next(点击next之后出现如下界面，然后选择好组织号，工程号，版本号即可)，最后点击Finish
2：maven项目创建好之后会报错，这里先在pom.xml中导入jar包，导入方式如下所示：这个pom配置好之后点击保存会将jar包下载到本地仓库，这个学习maven的时候都配置过，这个自己下去脑补吧；注意第304行struts2注解配置；

3：web.xml里面的dtd默认是2.3的，不过2.3的不支持el表达式，所以这里修改为2.5的。配置如下所示：
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> 3 <display-name>Archetype Created Web Application</display-name> 4 5 6 <display-name>Archetype Created Web Application</display-name> 7 8 </web-app>
4：项目配置好上面的，接下来开始写代码，首先从web.xml的配置开始，比如struts2的核心过滤器，spring核心配置文件，监听器；
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> 3 <display-name>Archetype Created Web Application</display-name> 4 5 6 <display-name>Archetype Created Web Application</display-name> 7 8 <!-- 配置spring的监听器 ,加载本地的springp配置文件--> 9 <context-param> 10 <param-name>contextConfigLocation</param-name> 11 <param-value>classpath:bean-*.xml</param-value> 12 </context-param> 13 14 <!-- 15 spring的监听器 spring-web-3.2.4.RELEASE.jar ==》org.springframework 16 ==》context ==》ContextLoaderListener 17 --> 18 <listener> 19 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 20 </listener> 21 22 23 <!-- 24 struts2的核心过滤器 25 1:filter-class ==》 struts2-core-2.3.8.jar ==》org.apache.struts2 26 ==》 dispatcher ==》 ng ==》filter ==》StrutsPrepareAndExecuteFilter 27 --> 28 <filter> 29 <filter-name>struts2Filter</filter-name> 30 <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> 31 </filter> 32 <filter-mapping> 33 <filter-name>struts2Filter</filter-name> 34 <url-pattern>/*</url-pattern> 35 </filter-mapping> 36 37 38 39 </web-app>
5：配置好之后就需要配置一下maven标准格式：在src/main下面创建一个java的文件夹，在src/下面创建一个test，在test下面创建java文件夹，配置如下所示：
6：将spring的配置文件bean-common.xml配置文件放到src/main/resources下面即可（src/main/resources也是根目录）：配置如下所示：
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans 3 xmlns="http://www.springframework.org/schema/beans" 4 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 5 xmlns:context="http://www.springframework.org/schema/context" 6 xmlns:tx="http://www.springframework.org/schema/tx" 7 xmlns:aop="http://www.springframework.org/schema/aop" 8 xsi:schemaLocation=" 9 http://www.springframework.org/schema/beans 10 http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 11 http://www.springframework.org/schema/context 12 http://www.springframework.org/schema/context/spring-context-3.0.xsd 13 http://www.springframework.org/schema/tx 14 http://www.springframework.org/schema/tx/spring-tx-3.0.xsd 15 http://www.springframework.org/schema/aop 16 http://www.springframework.org/schema/aop/spring-aop-3.0.xsd 17 "> 18 19 <!-- 使用注解annotation配置项目 --> 20 <context:annotation-config></context:annotation-config> 21 22 <!-- 使用扫描组件，扫描注解 ，自动扫描某某包,扫描所有的包--> 23 <context:component-scan base-package="com.bie"></context:component-scan> 24 25 <!-- 使用spring管理struts，使用sring管理hibernate --> 26 <!-- 27 配置数据源： 28 1：spring-jdbc-3.2.4.RELEASE.jar==》org.springframework.jdbc 29 ==》datasource 30 ==》DriverManagerDataSource 31 --> 32 <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 33 <property name="driverClassName" value="com.mysql.jdbc.Driver"></property> 34 <property name="url" value="jdbc:mysql:///crm_ssh?characterEncoding=UTF-8"></property> 35 <property name="username" value="root"></property> 36 <property name="password" value="123456"></property> 37 </bean> 38 39 <!-- 40 配置数据源生成hibernate的sessionFactory 41 1:spring-orm-3.2.4.RELEASE.jar ==》org.springframework.orm ==》hibernate4 42 ==LocalSessionFactoryBean 43 --> 44 <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> 45 <!-- 引入数据源 ,hibernate可以操作数据库,使用某个数据源生成sessionFactory--> 46 <property name="dataSource" ref="dataSource"></property> 47 48 <!-- 配置hibernate的相关配置,方言,显示sql语句等等 --> 49 <property name="hibernateProperties"> 50 <props> 51 <!-- 52 mysql的方言: 53 hibernate-core-4.1.7.Final.jar 54 --> 55 <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> 56 <!-- 打印sql语句 --> 57 <prop key="hibernate.show_sql">true</prop> 58 </props> 59 </property> 60 61 62 <!-- 之前开发使用的是映射文件，现在使用的是注解配置 --> 63 <property name="annotatedClasses"> 64 <!-- 这是一个集合，使用list集合进行赋值 --> 65 <list> 66 <!-- 使用注解的类都需要加到这里 --> 67 <value>com.bie.po.User</value> 68 <value>com.bie.po.Dept</value> 69 </list> 70 </property> 71 </bean> 72 73 <!-- 74 spring采用事务管理hibernate的事务 ：事务管理器：transactionManager 75 1:spring-orm-3.2.4.RELEASE.jar ==》org.springframework.orm ==》 76 hibernate4==》HibernateTransactionManager 77 --> 78 <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> 79 <!-- spring要管理事务，那么spring要对hibernate拥有处置权 --> 80 <property name="sessionFactory" ref="sessionFactory"></property> 81 </bean> 82 83 84 <!-- 在配置切面 之上配置事务管理的通知: 85 1:事务管理的通知要使用上面的事务管理:transactionManager 86 --> 87 <tx:advice id="transactionAdvice" transaction-manager="transactionManager"> 88 <tx:attributes> 89 <!-- 配置事务的传播特性 --> 90 <tx:method name="find*" read-only="true"/> 91 <tx:method name="get*" read-only="true"/> 92 <tx:method name="query*" read-only="true"/> 93 94 <!-- required:本操作内如果有事务，则使用事务，如果没有，则开启新的事务 --> 95 <tx:method name="add*" propagation="REQUIRED"/> 96 <tx:method name="update*" propagation="REQUIRED"/> 97 <tx:method name="delete*" propagation="REQUIRED"/> 98 </tx:attributes> 99 </tx:advice> 100 101 102 <!-- 103 配置切面,使用切面来管理事务 104 1:第一个※代表public 105 2:第二个※代表类 106 3:第三个※代表方法 107 4:第三个※(..)里面的..代表任意参数 108 --> 109 <aop:config> 110 <!-- 切入点 --> 111 <aop:pointcut expression="execution(* com.bie.service.impl.*.*(..))" id="transactionPointcut"></aop:pointcut> 112 113 <!-- 114 切入点应用到什么通知: 115 1:advice-ref:应用什么通知 116 2:pointcut-ref在那个切入点应用这个通知; 117 --> 118 <aop:advisor advice-ref="transactionAdvice" pointcut-ref="transactionPointcut"/> 119 </aop:config> 120 121 122 </beans>
7：配置好之后开始写实体类po下面的实体类；(注解方式配置实体类，配置如下所示)：
1 package com.bie.po; 2 3 import javax.persistence.Column; 4 import javax.persistence.Entity; 5 import javax.persistence.GeneratedValue; 6 import javax.persistence.GenerationType; 7 import javax.persistence.Id; 8 import javax.persistence.Table; 9 10 /** 11 * @author 作者:别先生 12 * @version 创建时间:2017年6月8日 上午11:55:43 13 * 类说明 14 * 1:使用注解完成实体类的配置 15 * 2:用户对应数据库的t_user表 16 */ 17 @Entity 18 @Table(name = "t_user") 19 public class User { 20 21 private Integer id;//主键编号 22 private String name;//姓名 23 private String account;//账号 24 private String password;//密码 25 26 //设置主键，然后设置主键自增 27 @Id 28 @GeneratedValue(strategy=GenerationType.AUTO) 29 @Column(name="t_userId") 30 public Integer getId() { 31 return id; 32 } 33 public void setId(Integer id) { 34 this.id = id; 35 } 36 37 @Column(name="t_userName") 38 public String getName() { 39 return name; 40 } 41 public void setName(String name) { 42 this.name = name; 43 } 44 45 @Column(name="t_userAccount") 46 public String getAccount() { 47 return account; 48 } 49 public void setAccount(String account) { 50 this.account = account; 51 } 52 53 @Column(name="t_userPwd") 54 public String getPassword() { 55 return password; 56 } 57 public void setPassword(String password) { 58 this.password = password; 59 } 60 61 }
8：配置一下struts2的配置文件，配置如下所示：
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE struts PUBLIC 3 "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" 4 "http://struts.apache.org/dtds/struts-2.0.dtd"> 5 6 <struts> 7 <!-- struts2-core-2.3.8.jar ==》org.apache.struts2==》default.properties --> 8 9 <!-- 表示struts2的action由spring来生成 --> 10 <constant name="struts.objectFactory" value="spring"></constant> 11 12 13 </struts>
9：配置好上面的验证一下，将项目加载到tomcat中，然后启动tomcat看看是否报错，我这里不报错，就不做多叙述了；
至此，ssh注解版框架就搭建成功，接下来就可以进行简单测试了......
10：测试的话，先写一个index.jsp页面，页面代码如下所示：
1 <%@ page language="java" contentType="text/html; charset=UTF-8" 2 pageEncoding="UTF-8"%> 3 <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> 4 <%@ taglib prefix="s" uri="/struts-tags"%> 5 <% 6 //获取绝对路径路径 ：路径path 7 String path = request.getContextPath(); 8 //基本路径:http://localhost:8080/ 9 String basePath = request.getScheme() +"://" 10 + request.getServerName() 11 +":" +request.getServerPort() + path + "/"; 12 //保存到session中 13 session.setAttribute("basePath", basePath); 14 %> 15 16 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 17 <html> 18 <head> 19 <base href="<%=basePath %>" /> 20 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> 21 <title>测试crm</title> 22 </head> 23 <body> 24 25 <a href="${basePath }user/queryById.action?userId=1">点击查看个人信息</a> 26 <h1>个人信息如下所示：</h1> 27 <ul> 28 <li>用户编号:${user.userId }</li> 29 <li>用户姓名:${user.userName }</li> 30 <li>用户账号:${user.userAccount }</li> 31 <li>用户密码:${user.userPwd }</li> 32 <li>用户部门:${user.dept.deptName }</li> 33 </ul> 34 35 36 37 </body> 38 </html>
11：页面点击超链接之后访问到struts2的action层，下面先给出action层的代码；
1 package com.bie.action; 2 3 import org.apache.struts2.convention.annotation.Action; 4 import org.apache.struts2.convention.annotation.Namespace; 5 import org.apache.struts2.convention.annotation.ParentPackage; 6 import org.apache.struts2.convention.annotation.Result; 7 import org.springframework.beans.factory.annotation.Autowired; 8 9 import com.bie.po.User; 10 import com.bie.service.UserInfoService; 11 import com.opensymphony.xwork2.ActionContext; 12 import com.opensymphony.xwork2.ActionSupport; 13 14 /** 15 * @author 作者:别先生 16 * @version 创建时间:2017年6月8日 下午4:27:30 17 * 类说明 18 */ 19 @ParentPackage("struts-default") 20 @Namespace("/user") 21 public class UserAction extends ActionSupport{ 22 23 private static final long serialVersionUID = 1L; 24 25 //自动注入到ioc容器中 26 @Autowired 27 private UserInfoService userInfoService; 28 29 private int id; 30 public void setId(int id) { 31 this.id = id; 32 } 33 public int getId() { 34 return id; 35 } 36 37 @Action( 38 value = "queryById", 39 results = { 40 @Result(name="success",location="/index.jsp") 41 } 42 ) 43 public String queryById(){ 44 45 //调用service层的方法进行查询 46 User user = userInfoService.queryById(id); 47 48 //将查询的信息保存到session中 49 ActionContext.getContext().getSession().put("user", user); 50 51 return "success"; 52 } 53 54 55 }
12：数据传输到action中，action对数据进行封装之后传到service层进行数据业务逻辑处理，这里写一下service层的代码；对service层的代码和dao层的代码先写接口，然后再写实现接口的类；
1 package com.bie.service; 2 3 import com.bie.po.User; 4 5 /** 6 * @author 作者:别先生 7 * @version 创建时间:2017年6月8日 下午3:43:03 8 * 类说明 9 */ 10 11 public interface UserInfoService { 12 13 /*** 14 * 根据用户编号查询 15 * @param id 16 * @return 17 */ 18 public User queryById(int id); 19 }
1 package com.bie.service.impl; 2 3 import org.springframework.beans.factory.annotation.Autowired; 4 import org.springframework.stereotype.Service; 5 6 import com.bie.dao.UserInfoDao; 7 import com.bie.po.User; 8 import com.bie.service.UserInfoService; 9 10 /** 11 * @author 作者:别先生 12 * @version 创建时间:2017年6月8日 下午3:43:13 13 * 类说明 14 */ 15 @Service 16 public class UserInfoServiceImpl implements UserInfoService{ 17 18 //自动注入到ioc容器中 19 @Autowired 20 private UserInfoDao userInfoDao; 21 22 public User queryById(int id) { 23 24 //直接调用dao层的方法查询之后返回到action层 25 return userInfoDao.queryById(id); 26 } 27 28 29 }
13：数据传输到dao层之后开始和数据库里的数据表进行交互和操作；
1 package com.bie.dao; 2 3 import com.bie.po.User; 4 5 /** 6 * @author 作者:别先生 7 * @version 创建时间:2017年6月8日 下午4:35:20 8 * 类说明 9 */ 10 11 public interface UserInfoDao { 12 13 /** 14 * 根据用户编号进行查询 15 * @param userId 16 * @return 17 */ 18 public User queryById(int userId); 19 }
1 package com.bie.dao.impl; 2 3 import org.hibernate.SessionFactory; 4 import org.springframework.beans.factory.annotation.Autowired; 5 import org.springframework.stereotype.Repository; 6 7 import com.bie.dao.UserInfoDao; 8 import com.bie.po.User; 9 10 /** 11 * @author 作者:别先生 12 * @version 创建时间:2017年6月8日 下午4:35:46 13 * 类说明 14 */ 15 @Repository 16 public class UserInfoDaoImpl implements UserInfoDao{ 17 18 //自动注入到ioc容器中 19 @Autowired 20 private SessionFactory sessionFactory; 21 22 public User queryById(int id) { 23 24 User user = (User) sessionFactory.getCurrentSession().get(User.class, id); 25 26 return user; 27 } 28 29 }
演示效果如下所示：
ssh注解版框架搭建先到这吧，以后有机会再深学吧。时间过的挺快的，马上就该出去找工作了......
