Eclipse完整工程如下 Jar包如下
CSDN下载地址:https://download.csdn.net/download/zhutouaizhuwxd/9721062
其中,整个工程主要可以分为四个部分(个人见解,怎么容易理解怎么来)
第一部分:配置文件
1、applicationContentx.xml:配置Spring容器相关内容.
1.1 hibernate.cfg.xml:
1.2 jdbc.properties:
2、Springmvc.xml:配置Springmvc相关内容
3、web.xml:配置整个工程相关内容
第二部分:(映射数据库)
1、实体类Entities
2、*.hbm.xml
第三部分:MVC:
1、控制层Controller(C)
2、业务逻辑层Service、Dao(M)
3、视图层index.jsp(V)
第四部分:JAR包
1、Spring3.X
2、Hibernate3.X
3、连接SqlServer2008数据库:sqljdbc4.jar(其他数据库使用对应的jar包即可)
4、数据库连接池:c3p0
5、commons-logging的jar包
具体代码如下:
第一部分:配置文件
1、applicationContentx.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd "> <!-- 自动扫描与装配Bean --> <context:component-scan base-package="com.zit" /> <context:annotation-config /> <context:property-placeholder location="classpath:config/jdbc.properties"/> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" > <!-- 数据连接信息 --> <property name="jdbcUrl" value="${jdbcUrl}"></property> <property name="driverClass" value="${driverClass}"></property> <property name="user" value="${user}"></property> <property name="password" value="${password}"></property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean" > <property name="dataSource" ref="dataSource"></property> <!-- 指定hibernate的映射实体类位置 --> <property name="mappingLocations" value="classpath:com/zit/entities/Student.hbm.xml"></property> <!-- 指定hibernate的配置文件位置 --> <property name="configLocation" value="classpath:config/hibernate.cfg.xml"></property> </bean> <!-- 配置一个事务管理器 --> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <tx:annotation-driven transaction-manager="transactionManager"/> </beans>
1.1 hibernate.cfg.xml
<?xml version='1.0' encoding='utf-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!-- SQL dialect 方言--> <property name="dialect">org.hibernate.dialect.SQLServerDialect</property> <property name="show_sql">true</property> <property name="hbm2ddl.auto">update</property> <!-- 映射数据库对应实体类:注解生效方式生效方式 --> <!-- <mapping class="Entity.Student"/> --> </session-factory> </hibernate-configuration>
1.2 jdbc.properties(根据个人的数据库,更改对应的参数,我的数据库名字是test)
driverClass = com.microsoft.sqlserver.jdbc.SQLServerDriver jdbcUrl = jdbc:sqlserver://localhost:1433;database=test user = sa password = xxxxx
2、Springmvc.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd "> <!-- 注解扫描包,注意换成自己的路径 --> <context:component-scan base-package="com.zit"> <!-- 只扫描@Controller的部分 --> <!-- <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> --> </context:component-scan> <!-- 定义视图解析器 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/"></property> <property name="suffix" value=".jsp"></property> </bean> </beans>
3、web.xml
<?xml version="1.0" encoding="UTF-8"?> <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" id="WebApp_ID" version="2.5"> <display-name>SSH</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- 加载所有的配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:config/applicationContext.xml</param-value> </context-param> <!-- 配置Spring监听 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 配置SpringMVC --> <servlet> <servlet-name>SSH</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:config/springmvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>SSH</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- 配置字符集 --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 加入Hibernate的过滤请求将session打开,不然在Dao层getCurrentSession()时报错 --> <filter> <filter-name>openSessionInViewFilter</filter-name> <filter-class> org.springframework.orm.hibernate3.support.OpenSessionInViewFilter </filter-class> </filter> <filter-mapping> <filter-name>openSessionInViewFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
第二部分:(映射数据库),我的数据库名字是test,里面有张Student表,有id(自增、主键),age,name三个字段
1、实体类Entities:Student.java
package com.zit.entities; import javax.persistence.Column; import javax.persistence.GeneratedValue; import javax.persistence.Id; public class Student { private int id; private String name; private int age; public Student(){} public Student(int id,String name,int age){ this.id=id; this.name=name; this.age=age; } public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } }
2、Student.hbm.xml:
<?xml version="1.0" encoding="utf-8"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> <hibernate-mapping> <class name="com.zit.entities.Student" table="Student"> <meta attribute="class-description"> This class contains the employee detail. </meta> <id name="id" type="int" column="id"> <generator class="native"/> </id> <property name="name" column="name" type="string"/> <property name="age" column="age" type="int"/> </class> </hibernate-mapping>
第三部分:MVC:
1、控制层Controller(C):StudentController.java
package com.zit.controller; import java.util.List; import javax.servlet.http.HttpServletRequest; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import com.zit.entities.Student; import com.zit.service.StudentService; @Controller @RequestMapping("/student") public class StudentController { @Autowired private StudentService studentService; @RequestMapping("/getAllStudent") public String getAllStudent(HttpServletRequest request){ String ss = request.getParameter("userName"); List<Student> students = studentService.getAllStudent(); for(Student s : students){ System.out.println(s.getId()); System.out.println(s.getName()); System.out.println(s.getAge()); } return "index";//返回index.jsp页面 } }
2、业务逻辑层Service、Dao(M)
2.1.1 StudentService.java
package com.zit.service; import java.util.List; import com.zit.entities.Student; public interface StudentService { public List<Student> getAllStudent(); }
2.1.2 StudentServiceImpl.java
package com.zit.service.impl; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Transactional; import com.zit.dao.StudentDao; import com.zit.entities.Student; import com.zit.service.StudentService; @Service public class StudentServiceImpl implements StudentService{ @Autowired private StudentDao studentDao; @Override public List<Student> getAllStudent() { return studentDao.getAllStudent(); } }
2.2.1 StudentDao.java
package com.zit.dao; import java.util.List; import com.zit.entities.Student; public interface StudentDao { public List<Student> getAllStudent(); }
2.2.1 StudentDaoImpl.java
package com.zit.dao.impl; import java.util.List; import javax.annotation.Resource; import org.hibernate.Query; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.springframework.stereotype.Repository; import org.springframework.transaction.annotation.Transactional; import com.zit.dao.StudentDao; import com.zit.entities.Student; @Repository public class StudentDaoImpl implements StudentDao{ @Resource(name = "sessionFactory") private SessionFactory sessionFactory; @Override @Transactional public List<Student> getAllStudent() { String hql = "from Student"; //getCurrentSession()比openSession()安全,注意web.xml中的配置,不然会报错 Session session = sessionFactory.getCurrentSession(); Query query = session.createQuery(hql); return query.list(); } }
3、视图层index.jsp(V):index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> <script type="text/javascript"> function addUser(){ var form = document.forms[0]; form.action = "/SSH/student/getAllStudent"; form.method="post"; form.submit(); } </script> </head> <body> <h1>添加用户</h1> <form action="" name="userForm"> 姓名:<input type="text" name="userName"> 年龄:<input type="text" name="age"> <input type="button" value="添加" onclick="addUser()"> </form> </body> </html>
以上配置文件是完整、可行的,建议不要擅自删除,
因为本人搭建期间遇到过几个报错,就是因为擅自删除配置文件,比如:
No Hibernate Session bound to thread, and configuration does not allow creat
等等,在此不一 一列举。
到此,搭建好一个能访问数据库的SSH工程,启动Tomcat,可运行查看效果。
这里的jsp页面只是用来打断点验证能否正常访问数据库的,没有实际意义……
