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個Jar包需要導入：

struts：2.3.15.3 【13個包】

hibernate : 3.6.10 【9個包】

spring: 3.2.0【基礎4+1，AOP4+DB2+測試1+web1+驅動1+連接池1】

還有：

Spring整合Hibernate：spring orm

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

二、Spring整合Hibernate

分爲有hibernate.cfg.xml和沒有hibernate.cfg.xml的兩種整合方式。下面學習一下沒有hibernate.cfg.xml的整合方式。

步驟1：

首先是在數據庫裏創建一個user表。

然後在domain包裏編寫user表對應的user類和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    [email protected]
 *
 */
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>

步驟2：

編寫DAO接口和DAO實現類

【注意】編寫實現類dao的時候，需要繼承HibernateDaoSupport，因爲Hibernate的底層實現需要SessionFactory（而JDBC需要的數據源，這裏是不同步的），繼承HibernateDaoSupport，自動創建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)
	 */
	@Override
	public void save(User user) {
		// TODO Auto-generated method stub
		this.getHibernateTemplate().save(user);
		
	}

	

}

步驟3：

編寫service接口和service實現類

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)
	 */
	@Override
	public void register(User user) {
		// TODO Auto-generated method stub
		userDao.save(user);
	}
	

}

步驟4：

編寫applicationContext.xml配置文件

1、配置數據源，這個一般用加載properties文件的方法來做。

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的實現類；

dao的ref是上面的sessionFactory

4、配置Service

service的class是service的實現類；

service的ref是上面的dao

5、配置事務管理

事務管理器的ref也是sessionFactory；

配置事務詳情，事務的method name是service實現類的方法名。

6、配置AOP編程

<?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"

       					   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>

步驟5：

編寫log4j.properties

### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### direct messages to file mylog.log ###
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=e\:mylog.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.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

步驟6：

編寫測試類

使用註解的方式，之前講Spring整合JUint的時候的那套註解。

/**
 * 
 */
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    [email protected]
 *
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:applicationContext.xml")
public class testSSH {

	@Autowired
	private UserService userService;
	
	@Test
	public void test() {
		User user = new User();
		user.setUsername("Lee");
		user.setPassword("0312");
		user.setAge(18);
		
		userService.register(user);
	}

}

三、Struts整合Spring

有兩種整合方法，第一種是在Spring中配置action，第二種是由Spring創建action，並按照名稱自動注入。

第一種：編寫action類，並配置給Spring，Spring注入service。還需要編寫struts.xml和web.xml。其中，web.xml需要確定配置文件，配置監聽器和配置前端控制前。

第二種：刪除Spring中action配置，要求Action類中提供與spring配置文件一致的service名稱（以便自動注入），然後配置struts.xml和web.xml。

操作步驟：

步驟1：

首先是在數據庫裏創建一個user表。

然後在domain包裏編寫user表對應的user類和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    [email protected]
 *
 */
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>

步驟2：

編寫DAO接口和DAO實現類

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)
	 */
	@Override
	public void save(User user) {
		// TODO Auto-generated method stub
		this.getHibernateTemplate().save(user);
		
	}

	

}

步驟3：

編寫Service接口和實現類

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)
	 */
	@Override
	public void register(User user) {
		// TODO Auto-generated method stub
		userDao.save(user);
	}
	

}

步驟4：

在web包下編寫action類。

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    [email protected]
 *
 */
public class UserAction extends ActionSupport implements ModelDriven<User> {

	//1 封裝數據
	private User user = new User();

	@Override
	public User getModel() {
		return user;
	}
	
	//2 service
	private UserService userService;
	public void setUserService(UserService userService) {
		this.userService = userService;
	}
	
	public String register(){
		userService.register(user);
		return "success";
	}
	

}

步驟5：

編寫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>
	<!-- 開發模式 -->
    <constant name="struts.devMode" value="true" />

    <package name="default" namespace="/" extends="struts-default">
    	<!-- 底層自動從spring容器中通過名稱獲得內容， getBean("userAction") -->
    	<action name="userAction_*" class="com.Lily.dianer.web.action.UserAction" method="{1}">
    		<result name="success">/messag.jsp</result>
    	</action>
    </package>
</struts>

步驟6：

兩個前端jsp頁面

<%@ 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">
		用戶名：<input type="text" name="username"/> <br/>
		密碼：<input type="password" name="password"/> <br/>
		年齡：<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>

步驟7：

編寫web.xml

首先是確定Spring xml的位置

然後是配置Spring的監聽器

然後是配置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 確定spring xml位置 -->
  <context-param>
  	<param-name>contextConfigLocation</param-name>
  	<param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  <!-- 2 spring監聽器 -->
  <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>
