jersey 过滤器

这里使用的Jersey 是 1.1 版本

1. web.xml 配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>restDemo</display-name>
  <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>
   
     <servlet>
      <servlet-name>Jersey REST Service</servlet-name>
    <servlet-class>
      com.sun.jersey.spi.container.servlet.ServletContainer
    </servlet-class>
      <init-param>
        <param-name>com.sun.jersey.spi.container.ContainerRequestFilters</param-name>  
          <param-value>com.mtour.rest.resources.requestFilter</param-value> 
      </init-param>
      <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
      <servlet-name>Jersey REST Service</servlet-name>
      <url-pattern>/rest/*</url-pattern>
    </servlet-mapping>
   
</web-app>

2. 新建类 requestFilter

package com.mtour.rest.resources;
 
import javax.ws.rs.WebApplicationException;
import javax.ws.rs.core.Response;
import javax.ws.rs.core.Response.Status;
 
import com.sun.jersey.spi.container.ContainerRequest;
import com.sun.jersey.spi.container.ContainerRequestFilter;
 
public class requestFilter implements ContainerRequestFilter{
 
    @Override
    public ContainerRequest filter(ContainerRequest arg0) {
        // TODO Auto-generated method stub
         
        throw new WebApplicationException(
                Response.status(Status.INTERNAL_SERVER_ERROR).build());
         
    }
     
}
