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：
<%--

<body>
<a href="account/findAll">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：
