爱一个人是一回事，拥有一个人是另外一回事，爱上并拥有一个人，更是另外一回事。 蝴蝶，是什么，是希望，是真正的希望。 上一章简单介绍了S2SH框架整合XML版(九),如果没有看过,请观看上一章。
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。
