SSH配置(三)-Spring配置

一、Spring配置

Spring包：hibernate-release-4.2.1.Final.zip

1、在WebContent->WEB-INF->lib下导入Spring所需jar包

路径：spring-framework-3.2.2.RELEASE\libs

另：还要导入struts2的spring插件struts2-spring-plugin-2.3.14.jar：

2、在src下添加dao,service的接口文件及实现类文件

①添加dao的接口及实现类文件

CommonDao.java代码：

import java.util.HashMap;import java.util.List;import org.hibernate.Query;import org.hibernate.Session;import org.hibernate.SessionFactory;public interface CommonDao {public void setSupperSessionFactory(SessionFactory sessionFactory);public String save(Object object);public void update(Object object);public void delete(Object object);public void delete(Class clazz, Serializable id);public <T>T get(Class<T> clazz, Serializable id);public List queryList(String hsql, HashMap<String, Object> params);}

CommonDaoImpl.java代码：

package com.jjh.ssh.dao.impl;import java.io.Serializable;import java.util.HashMap;import java.util.List;import javax.annotation.Resource;import org.hibernate.HibernateException;import org.hibernate.Query;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.springframework.stereotype.Repository;import com.jjh.ssh.dao.CommonDao;@Repositorypublic class CommonDaoImpl implements CommonDao {private SessionFactory sessionFactory;@Override@Resource(name="sessionFactory")public void setSupperSessionFactory(SessionFactory sessionFactory) {this.sessionFactory = sessionFactory;}protected Session getSession() {return sessionFactory.getCurrentSession();}@Overridepublic String save(Object object) {return (String)getSession().save(object);}@Overridepublic void update(Object object) {getSession().update(object);}@Overridepublic void delete(Object object) {getSession().delete(object);}@Overridepublic void delete(Class clazz, Serializable id) {Object o = getSession().load(clazz, id);getSession().delete(o);}@Overridepublic <T> T get(Class<T> clazz, Serializable id) {Object o = getSession().get(clazz,id);return (T)o; }@Overridepublic List queryList(String hsql, HashMap<String, Object> params) {Query q = createQuery(hsql, params);List l = q.list();return l;}@SuppressWarnings({ "unchecked", "rawtypes" })private Query createQuery(final String hsql, final HashMap<String, Object> params){Query q = getSession().createQuery(hsql);String[] keys = q.getNamedParameters();if(null != keys && null != params){for(String key : keys){if(!params.containsKey(key)){throw new RuntimeException("没有设置query语句中参数"+key+"的值");}Object v = params.get(key);q.setParameter(key, v);}}return q;}}

②添加service的接口及实现类文件

UserService.java代码：

package com.jjh.ssh.service;import java.util.List;import com.jjh.ssh.model.TaUser;public interface UserService {public void saveUser(TaUser user)throws Exception;public void deleteUser(TaUser user)throws Exception;public void deleteUser(String uid)throws Exception;public List<TaUser> listUsers()throws Exception;public TaUser getUser(String uid)throws Exception;}

UserServiceImpl.java代码：

package com.jjh.ssh.service.impl;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import com.jjh.ssh.dao.CommonDao;import com.jjh.ssh.model.TaUser;import com.jjh.ssh.service.UserService;@Servicepublic class UserServiceImpl implements UserService {@Autowiredprivate CommonDao commonDao;@Overridepublic void saveUser(TaUser user) throws Exception {if(null == user){throw new Exception("参数user为空");}commonDao.save(user);}@Overridepublic void deleteUser(TaUser user) throws Exception {// TODO Auto-generated method stubif(null == user){throw new Exception("参数user为空");}commonDao.delete(user);}@Overridepublic void deleteUser(String uid) throws Exception {if(null == uid || uid.length() == 0){throw new Exception("参数uid为空");}commonDao.delete(TaUser.class, uid);}@Overridepublic List<TaUser> listUsers() throws Exception {StringBuilder hsql = new StringBuilder("select u from TaUser u");List l = commonDao.queryList(hsql.toString(), null);return l;}@Overridepublic TaUser getUser(String uid) throws Exception {if(null != uid || uid.length() == 0){throw new Exception("参数uid为空");}TaUser u = commonDao.get(TaUser.class, uid);return u;}public CommonDao getCommonDao() {return commonDao;}public void setCommonDao(CommonDao commonDao) {this.commonDao = commonDao;}}

3、在src下添加spring-base.xml配置文件

spring-base.xml代码：

<?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-3.2.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context-3.2.xsd       http://www.springframework.org/schema/aop       http://www.springframework.org/schema/aop/spring-aop-3.2.xsd       http://www.springframework.org/schema/tx       http://www.springframework.org/schema/tx/spring-tx-3.2.xsd" default-autowire="byName" default-lazy-init="true"><description>Spring公共配置文件</description><!-- 使用Spring的注解 --><context:annotation-config /><!-- 扫描包，根据注解，实例化bean，并自动装配 --><context:component-scan base-package="com.jjh" /><!-- 会话工厂bean --><bean id="sessionFactory"class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"><property name="configLocation"> <value>classpath:hibernate.cfg.xml</value></property></bean> <!-- 事务管理者 --><bean id="transactionManager"class="org.springframework.orm.hibernate4.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory" /></bean><!-- 配置事务的传播特性 --><tx:advice id="txAdvice" transaction-manager="transactionManager"><tx:attributes><tx:method name="save*" propagation="REQUIRED" /><tx:method name="update*" propagation="REQUIRED" /><tx:method name="del*" propagation="REQUIRED" /><tx:method name="get*" propagation="REQUIRED" /><tx:method name="make*" propagation="REQUIRED" /><tx:method name="list*" propagation="REQUIRED" /><tx:method name="login*" propagation="REQUIRED" /><tx:method name="*" read-only="true" /></tx:attributes></tx:advice><!-- 那些类的哪些方法参与事务 --><aop:config><aop:pointcut id="allServiceMethod" expression="execution(public * com.jjh.ssh..*Service.*(..))" /><aop:advisor pointcut-ref="allServiceMethod" advice-ref="txAdvice" /></aop:config><aop:aspectj-autoproxy proxy-target-class="true"/>    </beans>

4、在WebContent->WEB-INf下的web.xml中添加spring的相关配置

web.xml中添加内容如下：

<!-- 上下文参数 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath*:/spring-*.xml</param-value></context-param><!-- 上下文加载监听 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener>   <!-- 编码过滤器 --><filter><filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param><init-param><param-name>forceEncoding</param-name><param-value>true</param-value></init-param></filter><filter-mapping><filter-name>encodingFilter</filter-name>  <url-pattern>/*</url-pattern></filter-mapping>

二、验证

1、修改UserAction.java文件如下：

package com.jjh.ssh.web;import java.util.List;import org.apache.struts2.convention.annotation.Namespace;import org.apache.struts2.convention.annotation.Result;import org.springframework.beans.factory.annotation.Autowired;import com.jjh.ssh.service.UserService;import com.opensymphony.xwork2.ActionSupport;@Namespace("/user")@Result(name = "userlist", location = "userlist.jsp")public class UserAction extends ActionSupport {@AutowiredUserService userService;private List userList;/** * 获取用户列表 * @return * @throws Exception */public String listUsers() throws Exception{System.out.println("-------listuser action begin-------");try {this.userList = userService.listUsers();} catch (Exception e) {e.printStackTrace();}System.out.println("-------listuser action end-------");return "userlist";}public List getUserList() {return userList;}public void setUserList(List userList) {this.userList = userList;}}

2、修改userlist.jsp文件如下：

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><%@ taglib uri="/struts-tags" prefix="s" %><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Insert title here</title></head><body>userlist for this!<s:iterator value="userList" var="users"><s:property value="#users.name" /> | <s:property value="#users.chname" /></s:iterator></body></html>

3、浏览器输入：http://localhost:8080/SSHFW/user/user!listUsers.do

显示结果如下：
