SSH

一、SSH

SSH就是Struts,Spring,Hibernate的整合。Spring整合Hibernate,Struts整合Spring。

其中，共有39个Jar包需要导入：

struts：2.3.15.3   【13个包】

hibernate : 3.6.10  【9个包】

spring: 3.2.0【基础4+1，AOP4+DB2+测试1+web1+驱动1+连接池1】

还有：

Spring整合Hibernate：spring orm

Struts整合Spring：struts2-spring-plugin-2.3.15.3.jar

 

二、Spring整合Hibernate

分为有hibernate.cfg.xml和没有hibernate.cfg.xml的两种整合方式。下面学习一下没有hibernate.cfg.xml的整合方式。

步骤1：

首先是在数据库里创建一个user表。

然后在domain包里编写user表对应的user类和user.hbm.xml

/** *  */package com.Lily.domain;/**  * *  * @author   LilyLee * @date     2017年6月28日 * @time     上午9:59:03 * @Version  1.0 * @email    [e-mail] * */public class User {/* * create table t_user(  id int primary key auto_increment,  username varchar(50),  password varchar(32),  age int ); */private Integer id;private String username;private String password;private Integer age;public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public Integer getAge() {return age;}public void setAge(Integer age) {this.age = age;}}

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE hibernate-mapping PUBLIC     "-//Hibernate/Hibernate Mapping DTD 3.0//EN"    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"><hibernate-mapping><class name="com.Lily.domain.User" table="t_user"><id name="id"><generator class="native"></generator></id><property name="username"></property><property name="password"></property><property name="age"></property></class></hibernate-mapping>

步骤2：

编写DAO接口和DAO实现类

【注意】编写实现类dao的时候，需要继承HibernateDaoSupport，因为Hibernate的底层实现需要SessionFactory（而JDBC需要的数据源，这里是不同步的），继承HibernateDaoSupport，自动创建HibernateTemplate模板。

public interface UserDao {public void save(User user);}

 

public class UserDaoImpl extends HibernateDaoSupport implements UserDao {/* (non-Javadoc) * @see com.Lily.dao.inter.UserDao#save(com.Lily.domain.User) */@Overridepublic void save(User user) {// TODO Auto-generated method stubthis.getHibernateTemplate().save(user);}}

步骤3：

编写service接口和service实现类

public interface UserService {public void register(User user);}

public class UserServiceImpl implements UserService{private UserDao userDao;public void setUserDao(UserDao userDao) {this.userDao = userDao;}/* (non-Javadoc) * @see com.Lily.service.inter.UserService#register(com.Lily.domain.User) */@Overridepublic void register(User user) {// TODO Auto-generated method stubuserDao.save(user);}}

步骤4：

编写applicationContext.xml配置文件

1、配置数据源，这个一般用加载properties文件的方法来做。

2、配置Hibernate的SessionFactory

           <propertyname="mappingLocations"value="classpath:com/itheima/domain/*.hbm.xml"></property>

3、配置DAO

dao的class是dao的实现类；

dao的ref是上面的sessionFactory

4、配置Service

service的class是service的实现类；

service的ref是上面的dao

5、配置事务管理

事务管理器的ref也是sessionFactory；

配置事务详情，事务的method name是service实现类的方法名。

6、配置AOP编程

<?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:aop="http://www.springframework.org/schema/aop"       xmlns:tx="http://www.springframework.org/schema/tx"       xmlns:context="http://www.springframework.org/schema/context"       xsi:schemaLocation="http://www.springframework.org/schema/beans           http://www.springframework.org/schema/beans/spring-beans-4.3.xsd          http://www.springframework.org/schema/tx           http://www.springframework.org/schema/tx/spring-tx.xsd          http://www.springframework.org/schema/aop           http://www.springframework.org/schema/aop/spring-aop.xsd          http://www.springframework.org/schema/context           http://www.springframework.org/schema/context/spring-context.xsd"><context:property-placeholder location="classpath:JdbcInfo.properties" /><bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"><property name="driverClass" value="${jdbc.driverClass}"></property><property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property><property name="user" value="${jdbc.user}"></property><property name="password"  value="${jdbc.password}"></property></bean><bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><property name="dataSource" ref="dataSource"></property><property name="hibernateProperties">   <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop><prop key="hibernate.show_sql">true</prop><prop key="hibernate.format_sql">true</prop><prop key="hibernate.hbm2ddl.auto">update</prop><prop key="hibernate.current_session_context_class">thread</prop></props></property><property name="mappingLocations" value="classpath:com/Lily/domain/*.hbm.xml"></property></bean><bean id="userDao" class="com.Lily.dao.impl.UserDaoImpl"><property name="sessionFactory" ref="sessionFactory"></property></bean><bean id="userService" class="com.Lily.service.impl.UserServiceImpl"><property name="userDao" ref="userDao"></property></bean><bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager" ><property name="sessionFactory" ref="sessionFactory"></property></bean><tx:advice id="txAdvice" transaction-manager="txManager"><tx:attributes><tx:method name="register"/></tx:attributes></tx:advice><aop:config><aop:advisor advice-ref="txAdvice" pointcut="execution(* com.Lily.service.inter..*.*(..))"/></aop:config></beans>

步骤5：

编写log4j.properties

### direct log messages to stdout ###log4j.appender.stdout=org.apache.log4j.ConsoleAppenderlog4j.appender.stdout.Target=System.outlog4j.appender.stdout.layout=org.apache.log4j.PatternLayoutlog4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n### direct messages to file mylog.log ###log4j.appender.file=org.apache.log4j.FileAppenderlog4j.appender.file.File=e\:mylog.loglog4j.appender.file.layout=org.apache.log4j.PatternLayoutlog4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n### set log levels - for more verbose logging change 'info' to 'debug' ###log4j.rootLogger=info, stdout

步骤6：

编写测试类

使用注解的方式，之前讲Spring整合JUint的时候的那套注解。

/** *  */package com.Lily.Test;import static org.junit.Assert.*;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import com.Lily.domain.User;import com.Lily.service.inter.UserService;/**  * *  * @author   LilyLee * @date     2017年6月28日 * @time     下午4:42:21 * @Version  1.0 * @email    [e-mail] * */@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations="classpath:applicationContext.xml")public class testSSH {@Autowiredprivate UserService userService;@Testpublic void test() {User user = new User();user.setUsername("Lee");user.setPassword("0312");user.setAge(18);userService.register(user);}}

 

三、Struts整合Spring

有两种整合方法，第一种是在Spring中配置action，第二种是由Spring创建action，并按照名称自动注入。

第一种：编写action类，并配置给Spring，Spring注入service。还需要编写struts.xml和web.xml。其中，web.xml需要确定配置文件，配置监听器和配置前端控制前。

第二种：删除Spring中action配置，要求Action类中提供与spring配置文件一致的service名称（以便自动注入），然后配置struts.xml和web.xml。

 

操作步骤：

步骤1：

首先是在数据库里创建一个user表。

然后在domain包里编写user表对应的user类和user.hbm.xml

/** *  */package com.Lily.dianer.domain;/**  * *  * @author   LilyLee * @date     2017年6月28日 * @time     上午9:59:03 * @Version  1.0 * @email    [e-mail] * */public class User {/* * create table t_user(  id int primary key auto_increment,  username varchar(50),  password varchar(32),  age int ); */private Integer id;private String username;private String password;private Integer age;public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public Integer getAge() {return age;}public void setAge(Integer age) {this.age = age;}}

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE hibernate-mapping PUBLIC     "-//Hibernate/Hibernate Mapping DTD 3.0//EN"    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"><hibernate-mapping><class name="com.Lily.dianer.domain.User" table="t_user"><id name="id"><generator class="native"></generator></id><property name="username"></property><property name="password"></property><property name="age"></property></class></hibernate-mapping>

步骤2：

编写DAO接口和DAO实现类

public interface UserDao {public void save(User user);}

public class UserDaoImpl extends HibernateDaoSupport implements UserDao {/* (non-Javadoc) * @see com.Lily.dao.inter.UserDao#save(com.Lily.domain.User) */@Overridepublic void save(User user) {// TODO Auto-generated method stubthis.getHibernateTemplate().save(user);}}

步骤3：

编写Service接口和实现类

public interface UserService {public void register(User user);}

public class UserServiceImpl implements UserService{private UserDao userDao;public void setUserDao(UserDao userDao) {this.userDao = userDao;}/* (non-Javadoc) * @see com.Lily.service.inter.UserService#register(com.Lily.domain.User) */@Overridepublic void register(User user) {// TODO Auto-generated method stubuserDao.save(user);}}

步骤4：

在web包下编写action类。

注意方法名需要跟Service相同。

/** *  */package com.Lily.dianer.web.action;import com.opensymphony.xwork2.ActionSupport;import com.opensymphony.xwork2.ModelDriven;import com.Lily.dianer.domain.User;import com.Lily.dianer.service.inter.UserService;import com.Lily.dianer.service.impl.*;/**  * *  * @author   LilyLee * @date     2017年6月28日 * @time     下午7:37:02 * @Version  1.0 * @email    [e-mail] * */public class UserAction extends ActionSupport implements ModelDriven<User> {//1 封装数据private User user = new User();@Overridepublic User getModel() {return user;}//2 serviceprivate UserService userService;public void setUserService(UserService userService) {this.userService = userService;}public String register(){userService.register(user);return "success";}}

步骤5：

编写struts.xml 整合Spring

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN""http://struts.apache.org/dtds/struts-2.3.dtd"><struts><!-- 开发模式 -->    <constant name="struts.devMode" value="true" />    <package name="default" namespace="/" extends="struts-default">    <!-- 底层自动从spring容器中通过名称获得内容， getBean("userAction") -->    <action name="userAction_*" class="com.Lily.dianer.web.action.UserAction" method="{1}">    <result name="success">/messag.jsp</result>    </action>    </package></struts>

步骤6：

两个前端jsp页面

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!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><form action="${pageContext.request.contextPath}/userAction_register" method="post">用户名：<input type="text" name="username"/> <br/>密码：<input type="password" name="password"/> <br/>年龄：<input type="text" name="age"/> <br/><input type="submit" /></form> </body></html>

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!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>成功</body></html>

步骤7：

编写web.xml

首先是确定Spring xml的位置

然后是配置Spring的监听器

然后是配置Struts的前端控制器.

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">  <!-- 1 确定spring xml位置 -->  <context-param>  <param-name>contextConfigLocation</param-name>  <param-value>classpath:applicationContext.xml</param-value>  </context-param>  <!-- 2 spring监听器 -->  <listener>  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>  <!-- 3 struts 前端控制器 -->  <filter>  <filter-name>struts2</filter-name>  <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>  </filter>  <filter-mapping>  <filter-name>struts2</filter-name>  <url-pattern>/*</url-pattern>  </filter-mapping></web-app>
