首先是项目和所需要的包截图:
修改xml文件:
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <servlet> <servlet-name>dispatcherServlet</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/hib-config.xml,/WEB-INF/web-config.xml, /WEB-INF/service-config.xml,/WEB-INF/dao-config.xml </param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> </web-app>
增加web-config.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" 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-2.5.xsd"> <!-- Controller方法调用规则定义 --> <bean id="paraMethodResolver" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver"> <property name="paramName" value="action" /> <property name="defaultMethodName" value="list" /> </bean> <!-- 页面view层基本信息设定 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"></property> <property name="suffix" value=".jsp"></property> </bean> <!-- servlet映射列表,所有控制层Controller的servlet在这里定义 --> <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <props> <prop key="user.do">userController</prop> </props> </property> </bean> <bean id="userController" class="com.sxt.action.UserController"> <property name="userService" ref="userService"></property> </bean> </beans>
增加service-config.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" 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-2.5.xsd"> <bean id="userService" class="com.sxt.service.UserService"> <property name="userDao" ref="userDao"></property> </bean> </beans>
增加dao-config.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" 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-2.5.xsd"> <bean id="userDao" class="com.sxt.dao.UserDao"> <property name="hibernateTemplate" ref="hibernateTemplate"></property> </bean> </beans>
增加hib-config.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd "> <context:component-scan base-package="com.sxt"></context:component-scan> <!-- 支持aop注解 --> <aop:aspectj-autoproxy></aop:aspectj-autoproxy> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"></property> <property name="url" value="jdbc:mysql://localhost:3306/crud"></property> <property name="username" value="root"></property> <property name="password" value="root"></property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource"> <ref bean="dataSource"></ref> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect"> org.hibernate.dialect.MySQLDialect </prop> <prop key="hibernate.show_sql"> true </prop> <prop key="hibernate.hbm2ddl.auto">update</prop> </props> </property> <property name="packagesToScan"> <value>com.sxt.po</value> </property> </bean> <bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 配置一个JdbcTemplate实例 --> <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate"> <property name="dataSource" ref="dataSource"></property> </bean> <!-- 配置事务管理 --> <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <tx:annotation-driven transaction-manager="txManager"/> <aop:config> <aop:pointcut expression="execution(public * com.sxt.service.impl.*.*(..))" id="businessService"/> <aop:advisor advice-ref="txAdvice" pointcut-ref="businessService"/> </aop:config> <tx:advice id="txAdvice" transaction-manager="txManager"> <tx:attributes> <tx:method name="find*" read-only="true" propagation="NOT_SUPPORTED"/> <!-- get开头的方法不需要在事务中运行。有些情况是没有必要使用事务的。比如获取数据,开启事务本身对性能本身是有一定的影响的 --> <tx:method name="*"/> </tx:attributes> </tx:advice> </beans>
各类包的代码如下:
package com.sxt.po; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; @Entity public class User { private int id ; private String name ; @Id @GeneratedValue(strategy=GenerationType.AUTO) 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; } }
userDao
package com.sxt.dao; import org.springframework.orm.hibernate3.HibernateTemplate; import com.sxt.po.User; public class UserDao { private HibernateTemplate hibernateTemplate ; public void add(User u){ System.out.println("userDao.add()"); hibernateTemplate.save(u) ; } public HibernateTemplate getHibernateTemplate() { return hibernateTemplate; } public void setHibernateTemplate(HibernateTemplate hibernateTemplate) { this.hibernateTemplate = hibernateTemplate; } }
userService
package com.sxt.service; import com.sxt.dao.UserDao; import com.sxt.po.User; public class UserService { private UserDao userDao ; public void add(String name){ System.out.println("UserService.add()"); User u = new User() ; u.setName(name) ; userDao.add(u) ; } public UserDao getUserDao() { return userDao; } public void setUserDao(UserDao userDao) { this.userDao = userDao; } }
userController
package com.sxt.action; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.mvc.Controller; import com.sxt.service.UserService; public class UserController implements Controller{ private UserService userService ; @Override public ModelAndView handleRequest(HttpServletRequest req, HttpServletResponse resp) throws Exception { // TODO Auto-generated method stub System.out.println("HelloController.handleRequest()"); req.setAttribute("a", "bbb") ; userService.add(req.getParameter("name")) ; return new ModelAndView("index2"); } public UserService getUserService() { return userService; } public void setUserService(UserService userService) { this.userService = userService; } }
下面是显示层的jsp代码:
<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>My JSP 'index.jsp' starting page</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <!-- <link rel="stylesheet" type="text/css" href="styles.css"> --> </head> <body> <form action="user.do" > 姓名:<input type="text" name="name" /> 登录:<input type="submit" value="登录"> </form> </body> </html>
index2.jsp
<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>My JSP 'index2.jsp' starting page</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <!-- <link rel="stylesheet" type="text/css" href="styles.css"> --> </head> <body> <%=request.getAttribute("a") %> </body> </html>
