struts2+spring总结

web.xml配置:

<?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">
 <filter>
  <filter-name>struts2</filter-name>
  <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
 </filter>
 
  <filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>/*</url-pattern>
  </filter-mapping>
  

<!--applicationContext*.xml具体位置
     <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext*.xml</param-value>
     </context-param>

 -->


 <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

 

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

 

struts.xml配置:

    <constant name="struts.objectFactory" value="spring"/>

action交给Spring来管理,action中的class类=是applicationContext.xml中bean中配置的,如:

    <action name="adminLoginAction" class="AdminLoginAction" method="AdminLogin">

 

applicationContext.xml配置:

<?xml version="1.0" encoding="utf-8"?>
<beans
 xmlns="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.springframework.org/schema/beans
 http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
 
<!-- bean里的id为struts.xml中action里映射实体Action类的一个标志,这里的class才是真实的映射类地址 --> 
 <bean id="SysUserDao" class="common.login.SysUserDao" />
 <bean id="AdminLoginAction" class="common.login.LoginAction" scope="prototype">
  <property name="sysUserDao">
   <ref bean="SysUserDao"/>
  </property>
 </bean>
</beans>

 

注意:在Action中或其他的类中引用到另外的一人类,只需要在这个类中声明一下,get/set一下就O了,如:

  LoginAction中:
       
private SysUserDao sysUserDao; (必须要写地)

 

        public SysUserDao getSysUserDao() {
            return sysUserDao;
         }

        public void setSysUserDao(SysUserDao sysUserDao) {
            this.sysUserDao = sysUserDao;
         }

   下面就可以用了:sysUserDao.方法就可以了
