servlet与spring注入
在servlet中操作程序，需要用到spring管理时，由于脱离了struts的跳转层，所以需要来配置servlet代理来注入spring
web.xml配置

代码: 全选
<servlet>
<servlet-name>PayMoneyApi</servlet-name>
<servlet-class>com.holpe.action.systemPack.ServletToBeanProxy</servlet-class>//代理类，下面有贴出代码
<init-param>
<param-name>targetBean</param-name>
<param-value>servletBean</param-value>
</init-param>
</servlet>

<servlet-mapping>
<servlet-name>PayMoneyApi</servlet-name>
<url-pattern>/PayMoneyApi</url-pattern>
</servlet-mapping>


spring的配置文件

代码: 全选
<bean id="servletBean"
class="com.holpe.action.systemPack.PayMoneyInteface">//servlet处理类
//注入
<property name="dealMangerAction">
<ref bean="Service"/>
</property>
<property name="userService">
<ref bean="userCenterService"/>
</property>
<property name="userMoneySer">
<ref bean="userMoneyService"/>
</property>
</bean>


下面贴出代理类的写法

代码: 全选
package com.holpe.action.systemPack;

import java.io.IOException;

import javax.servlet.GenericServlet;
import javax.servlet.Servlet;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

@SuppressWarnings("serial")
public class ServletToBeanProxy extends GenericServlet {

private String targetBean;

private Servlet proxy;


public void init() throws ServletException {
System.out.println("proxy init");
this.targetBean = getInitParameter("targetBean");
getServletBean();
proxy.init(getServletConfig());
}


public void service(ServletRequest req, ServletResponse res)
throws ServletException, IOException {

proxy.service(req, res);

}


private void getServletBean() {

WebApplicationContext wac =
WebApplicationContextUtils.getRequiredWebApplicationContext(getServletContext());
this.proxy = (Servlet)wac.getBean(targetBean);

}


}
