ssm整合之Spring整合MyBatis框架配置事务
1.在applicationContext.xml修改代码如下:
<?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:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!--开启注解的扫描,希望处理service和dao,controller不需要Spring框架去处理--> <context:component-scan base-package="com.txw"> <!--配置哪些注解不扫描--> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" /> </context:component-scan> <!--Spring整合MyBatis框架--> <!--配置连接池--> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="com.mysql.jdbc.Driver"/> <property name="jdbcUrl" value="jdbc:mysql:///ssm"/> <property name="user" value="root"/> <property name="password" value="123456"/> </bean> <!--配置SqlSessionFactory工厂--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> </bean> <!--配置AccountDao接口所在包--> <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.txw.dao"/> </bean> <!--配置Spring框架声明式事务管理--> <!--配置事务管理器--> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <!--配置事务通知--> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="find*" read-only="true"/> <tx:method name="*" isolation="DEFAULT"/> </tx:attributes> </tx:advice> <!--配置AOP增强--> <aop:config> <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.txw.service.impl.*ServiceImpl.*(..))"/> </aop:config> </beans>
2.修改index.jsp的代码如下:
<%-- Created by IntelliJ IDEA. User: Adair Date: 2020/7/8 0008 Time: 14:26 To change this template use File | Settings | File Templates. --%> <%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>首页</title> </head> <body> <a href="account/findAll" rel="external nofollow" >测试查询</a> <h3>测试保存</h3> <form action="account/save" method="post"> 姓名:<input type="text" name="name" /><br/> 金额:<input type="text" name="money" /><br/> <input type="submit" value="保存"/><br/> </form> </body> </html>
3.修改帐户的控制类的代码如下:
package com.txw.controller; import com.txw.domain.Account; import com.txw.service.AccountService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.util.List; /** *帐户的控制类 * @author Adair */ @Controller @RequestMapping(path = "/account") @SuppressWarnings("all") // 注解警告信息 public class AccountController { @Autowired // 自动类型注入 private AccountService accountService; @RequestMapping(value = "/findAll") public String findAll(Model model){ System.out.println("表现层:查询所有账户..."); // 调用findAll()方法 List<Account> list = accountService.findAll(); // 进行存储 model.addAttribute("list",list); return "list"; } /** * 保存 * @return */ @RequestMapping("/save") public void save(Account account, HttpServletRequest request, HttpServletResponse response) throws Exception { accountService.saveAccount(account); response.sendRedirect(request.getContextPath()+"/account/findAll"); return; } }
4.重新部署项目,运行如图所示:
5.通过浏览器访问http://localhost:8080/如图所示:
6.填写姓名和金额如图所示:
7.点击保存会跳转到如图所示的界面:
8.控制台打印结果如图所示:
