struts、hibernate与spring整合

框架的搭建

1搭建Spring3

1.1 导入spring的jar包

1.2 把spring.xml放入src/main/resources中

<?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:c="http://www.springframework.org/schema/c" xmlns:cache="http://www.springframework.org/schema/cache" xmlns:context="http://www.springframework.org/schema/context" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:lang="http://www.springframework.org/schema/lang" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:p="http://www.springframework.org/schema/p" xmlns:task="http://www.springframework.org/schema/task" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:util="http://www.springframework.org/schema/util"
	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/cache http://www.springframework.org/schema/cache/spring-cache.xsd

		http://www.springframework.org/schema/lang http://www.springframework.org/schema/lang/spring-lang.xsd

		http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd
		http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
		http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd">

	<!-- 引入项目配置文件 -->
	<!-- <context:property-placeholder location="classpath:config.properties" /> -->
	<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="locations">
			<list>
				<value>classpath:config.properties</value>
			</list>
		</property>
	</bean>

	<!-- 自动扫描dao和service包(自动注入) -->
	<context:component-scan base-package="sy.dao,sy.service" />
</beans>
 

1.3 在web.xml中配置spring监听器和配置文件位置  

<!-- spring配置文件位置 -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring.xml</param-value>
</context-param>
<!--spring监听器-->
<listener>
   <listener-class>
       org.springframework.web.context.ContextLoaderListener
   </listener-class>
</listener>

1.4 使用annotation方式把类加入spring容器中：

如果是为service包中类添加annotation：

@Service("userService")
public class UserServiceImpl implements UserServiceI {}

如果是为 dao 包中类添加 annotation ：    

@Repository("userDao")
public class UserDaoImpl implements UserDaoI {}

1.5 建立测试类测试spring

public class TestSpring {
    @Test
    public void test() {
        ApplicationContext ac = new ClassPathXmlApplicationContext(new String[]{"classpath:spring.xml"});
        UserServiceI userService = (UserServiceI) ac.getBean("userService");
        userService.test();
    }
}

2  搭建 Struts2 并整合 spring3 

2.1 导入struts2的jar包

2.2 把struts.xml放入src/main/resources中

<?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>

	<!-- 指定由spring负责action对象的创建 -->
	<constant name="struts.objectFactory" value="spring" />
	<!-- 所有匹配*.action的请求都由struts2处理 -->
	<constant name="struts.action.extension" value="action" />
	<!-- 是否启用开发模式 -->
	<constant name="struts.devMode" value="true" />
	<!-- struts配置文件改动后，是否重新加载 -->
	<constant name="struts.configuration.xml.reload" value="false" />
	<!-- 设置浏览器是否缓存静态内容 -->
	<constant name="struts.serve.static.browserCache" value="false" />
	<!-- 请求参数的编码方式 -->
	<constant name="struts.i18n.encoding" value="utf-8" />
	<!-- 每次HTTP请求系统都重新加载资源文件，有助于开发 -->
	<constant name="struts.i18n.reload" value="false" />
	<!-- 文件上传最大值 -->
	<constant name="struts.multipart.maxSize" value="104857600" />
	<!-- 让struts2支持动态方法调用 -->
	<constant name="struts.enable.DynamicMethodInvocation" value="true" />
	<!-- Action名称中是否可使用斜线 -->
	<constant name="struts.enable.SlashesInActionNames" value="false" />
	<!-- 允许标签中使用表达式语法 -->
	<constant name="struts.tag.altSyntax" value="true" />
	<!-- 对于WebLogic,Orion,OC4J此属性应该设置成true -->
	<constant name="struts.dispatcher.parametersWorkaround" value="false" />

	<package name="basePackage" extends="struts-default">
		
	</package>

</struts>
 

2.3 在web.xml中配置struts2的filter

<!-- Struts2配置 -->
<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>

2.4 使用注解的方式配置action

@ParentPackage("basePackage")
@Action(“userAction”)
public class UserAction {
    public void test() {
        System.out.println("struts successful");
    }
}

3 搭建Hibernate4并整合spring3 
3.1导入Hibernate4的jar包

3.2把spring-hibernate.xml放入src/main/resources中

<?xml version="1.0" encoding="UTF-8"?>

</beans> 

3.3     在web.xml中添加Hibernate的配置

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        classpath:spring.xml,classpath:spring-hibernate.xml
    </param-value>
</context-param>
<!-- openSessionInView配置 -->
<filter>
    <filter-name>openSessionInViewFilter</filter-name>
    <filter-class>
org.springframework.orm.hibernate4.support.OpenSessionInViewFilter
    </filter-class>
	<init-param>
	    <param-name>singleSession</param-name>
	    <param-value>true</param-value>
	</init-param>
</filter>
<filter-mapping>
    <filter-name>openSessionInViewFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

3.4 在UserDao中使用SessionFactory来操作数据库

@Repository("userDao")
public class UserDaoImpl implements UserDaoI {
	
    private SessionFactory sessionFactory;
	
    public SessionFactory getSessionFactory() {
	return sessionFactory;
    }

    @Autowired
    public void setSessionFactory(SessionFactory sessionFactory) {
	this.sessionFactory = sessionFactory;
    }
    @Override
    public Serializable save(Tuser tuser) {
	return this.sessionFactory.getCurrentSession().save(tuser);
    }
}
