一. S2SH 注解版
将bean 的创建，与事务管理进行注解形式的开发。 与上一章有着非常紧密的联系，如果没有看过上一章，请观看上一章。
二. 开启注解扫描
<!-- 开启注解扫描 --> <context:component-scan base-package="com.yjl"></context:component-scan>
三.将bean 的xml 形式创建,事务控制进行删除。
<!--全部进行移除--> <!-- 设置userDao类 --> <bean id="userDao" class="com.yjl.dao.impl.UserDaoImpl"> <property name="hibernateTemplate" ref="hibernateTemplate"></property> </bean> <!-- 设置userService --> <bean id="userService" class="com.yjl.service.impl.UserServiceImpl"> <property name="userDao" ref="userDao"></property> </bean> <!-- 设置userAction --> <bean id="userAction" class="com.yjl.web.action.UserAction" scope="prototype"> <property name="userService" ref="userService"></property> </bean> <!--移除事务--> <!-- 配置事务管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"></property> </bean> <!-- 配置事务 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="insert*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="edit*" propagation="REQUIRED" /> <tx:method name="save*" propagation="REQUIRED" /> <tx:method name="add*" propagation="REQUIRED" /> <tx:method name="new*" propagation="REQUIRED" /> <tx:method name="set*" propagation="REQUIRED" /> <tx:method name="remove*" propagation="REQUIRED" /> <tx:method name="delete*" propagation="REQUIRED" /> <tx:method name="change*" propagation="REQUIRED" /> <tx:method name="get*" propagation="REQUIRED" read-only="true" /> <tx:method name="find*" propagation="REQUIRED" read-only="true" /> <tx:method name="load*" propagation="REQUIRED" read-only="true" /> <tx:method name="*" propagation="REQUIRED" read-only="true" /> </tx:attributes> </tx:advice> <!-- 配置aop --> <aop:config> <aop:pointcut expression="execution( * com.yjl.service.impl.*.*(..))" id="pointCut1"/> <aop:advisor advice-ref="txAdvice" pointcut-ref="pointCut1"/> </aop:config>
四. UserDaoImpl 的写法
package com.yjl.dao.impl; import java.util.ArrayList; import java.util.List; import javax.annotation.Resource; import org.springframework.orm.hibernate5.HibernateTemplate; import org.springframework.stereotype.Repository; import com.yjl.dao.UserDao; import com.yjl.pojo.User; /** @author:yuejl @date: 2019年5月22日 下午8:04:43 @Description 类的相关描述 */ @Repository("userDao") public class UserDaoImpl implements UserDao { @Resource(name="hibernateTemplate") private HibernateTemplate hibernateTemplate; @SuppressWarnings("unchecked") @Override public List<User> findAll() { System.out.println("执行了查询全部的方法"); List<User> userList=new ArrayList<User>(); String hql="from User"; System.out.println("输出值为:"+hibernateTemplate); userList=(List<User>) hibernateTemplate.find(hql); return userList; } }
五. UserServiceImpl 的写法
package com.yjl.service.impl; import java.util.List; import javax.annotation.Resource; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Transactional; import com.yjl.dao.UserDao; import com.yjl.pojo.User; import com.yjl.service.UserService; /** @author:yuejl @date: 2019年5月22日 下午8:05:15 @Description 类的相关描述 */ @Service("userService") @Transactional public class UserServiceImpl implements UserService { @Resource(name="userDao") private UserDao userDao; @Override public List<User> findAll() { return userDao.findAll(); } }
六. UserAction 的写法
package com.yjl.web.action; import java.util.List; import javax.annotation.Resource; import org.springframework.context.annotation.Scope; import org.springframework.stereotype.Controller; import com.opensymphony.xwork2.ActionContext; import com.yjl.pojo.User; import com.yjl.service.UserService; /** @author:yuejl @date: 2019年5月22日 下午8:05:24 @Description 类的相关描述 */ @Controller @Scope("prototype") public class UserAction { @Resource(name="userService") private UserService userService; public String list(){ List<User> userList=userService.findAll(); ActionContext.getContext().getValueStack(). set("userList", userList); return "list"; } public UserService getUserService() { return userService; } public void setUserService(UserService userService) { this.userService = userService; } }
这样，就替换了bean 的创建，但还没有替换事务控制
七.事务控制注解
<!-- 配置事务管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"></property> </bean> <!-- 开启注解事务管理 --> <tx:annotation-driven transaction-manager="transactionManager"/>
八. 其余配置
其余的配置，都是不变的。 但是为了方便，将所有的配置信息都列举出来。
八.一 applicationContext.xml
