ssh(struts2_spring4_hibernate4)整合

新手學習中，就看成筆記了...

先來講一下配置文件版的：

1.首先須要導入須要用到的jar包

2.配置web.xml

?xml version="1.0" encoding="UTF-8"?>
<web-a<pp xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xmlns="http://xmlns.jcp.org/xml/ns/javaee" 
          xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee 
          http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">

	<!-- 配置spring -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:applicationContext.xml</param-value>
	</context-param>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	
	<!-- 配置struts2 -->
	<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>*.action</url-pattern>
	</filter-mapping>

  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
</web-app>

3.編寫Dao接口以及Dao的實現類

    Dao接口：

public interface UserDaoI {
	public List<User> getAll();
}

    Dao實現類

public class UserDaoImpl extends HibernateDaoSupport implements UserDaoI {

	@Override
	public List<User> getAll() {
		return (List<User>) this.getHibernateTemplate().find("from User");
	}

}

4.編寫Service接口以及Service的實現類

    Service接口

public interface UserServiceI {
	public List<User> getAll();
}

    Service實現類

public class UserServiceImpl implements UserServiceI {
	private UserDaoI userDao;
	
	public void setUserDao(UserDaoI userDao) {
		this.userDao = userDao;
	}

	@Override
	public List<User> getAll() {
		return userDao.getAll();
	}

}

5.編寫Action

public class UserAction {
	private UserServiceI userService;
	private List<User> list;
	
	public String list() {
		list = userService.getAll();
		return "success";
	}
	
	public void setUserService(UserServiceI userService) {
		this.userService = userService;
	}

	public List<User> getList() {
		return list;
	}

	public void setList(List<User> list) {
		this.list = list;
	}
}

6.配置applicationContext.xml

    頭文件中spring-context的xsd版本不寫有時候會找不到會報錯，最好寫上，好比：spring-context-2.5.xsd

<?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.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">

	<!-- 導入db.properties配置文件 -->
	<context:property-placeholder location="classpath:db.properties"/>
	<!-- 配置數據源 -->
	<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
		<property name="driverClassName" value="${jdbc_driverClassName}"></property>
		<property name="url" value="${jdbc_url}"></property>
		<property name="username" value="${jdbc_username}"></property>
		<property name="password" value="${jdbc_password}"></property>
	</bean>
	<!-- 聲明式事務管理 -->
	<!-- 配置事務管理器 -->
	<bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource"/>
	</bean>
	<!-- 配置事務通知 -->
	<tx:advice id="txAdvice" transaction-manager="txManager">
		<tx:attributes>
			<tx:method name="add*" propagation="REQUIRED"/>
			<tx:method name="save" propagation="SUPPORTS"/>
			<tx:method name="get*" read-only="true"/>
			<tx:method name="update" propagation="REQUIRED"/>
			<tx:method name="delete" propagation="REQUIRED"/>
			<tx:method name="select" propagation="REQUIRED"/>
			<tx:method name="*" propagation="REQUIRED"/>
		</tx:attributes>
	</tx:advice>
	<!-- 配置aop -->
	<aop:config>
		<aop:pointcut expression="execution(* com.bjsxt.service.impl.*.*(..))" id="pointcut"/>
		<aop:advisor advice-ref="txAdvice" pointcut-ref="pointcut"/>
	</aop:config>
	<!-- 定義hibernate的SessionFactory -->
	<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
		<!-- 依賴注入數據源 -->
		<property name="dataSource" ref="dataSource"></property>
		<!-- mappingResources指定具體的映射文件名 -->
		<!-- mappingLocations可使用通配符 -->
		<property name="mappingLocations">
			<list>
				<value>classpath:com/bjsxt/vo/*.hbm.xml</value>
			</list>
		</property>
		<!-- 定義hibernate的SessionFactory的屬性 -->
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">${hibernate.dialect}</prop>
				<prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>
				<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
				<prop key="hibernate.format_sql">${hibernate.format_sql}</prop>
			</props>
		</property>
	</bean>
	<!-- 定義HibernateDaoSupport -->
	<bean id="hibernateDaoSupport" class="org.springframework.orm.hibernate4.support.HibernateDaoSupport"
		abstract="true">
		<property name="sessionFactory" ref="sessionFactory"></property>
	</bean>
	
	<import resource="config/spring/user.xml"/>
</beans>

7. config/spring/user.xml 建議頭文件與主配置文件一致

<?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.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">

	<bean id="userDao" class="com.bjsxt.dao.impl.UserDaoImpl" parent="hibernateDaoSupport"></bean>
	<bean id="userService" class="com.bjsxt.service.impl.UserServiceImpl">
		<property name="userDao" ref="userDao"></property>
	</bean>
	<bean id="userAction" class="com.bjsxt.action.UserAction" scope="prototype">
		<property name="userService" ref="userService"></property>
	</bean>
</beans>

8.配置struts.xml

<?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>
	<include file="config/struts/user.xml"></include>
</struts>

9.config/struts/user.xml

<?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>
	<package name="user" namespace="/user" extends="struts-default">
		<!-- 整合spring之後action的class屬性能夠寫bean的id -->
		<action name="list" class="userAction" method="list">
			<result>/list.jsp</result>
		</action>
	</package>
</struts>

10.文件結構
