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);
}
}
