SpringBoot+jersey实现

1、在maven配置文件中需要添加如下信息

<!-- spring-boot-starter-jersey -->
	<dependency>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-jersey</artifactId>
	</dependency>

2、实现ResourceConfig类对指定的包进行扫描注册指定的接口。并将该实现类注册到SpringBoot容器中。

package com.kingdee.config;
import javax.ws.rs.ApplicationPath;
import org.glassfish.jersey.server.ResourceConfig;
import org.springframework.stereotype.Component;

import com.kingdee.filter.MyContainerRequestFilter;
import com.kingdee.filter.MyContainerResponseFilter;

@Component
@ApplicationPath("/microblog")
public class MicroblogResourceConfig extends ResourceConfig{
	public MicroblogResourceConfig() {
		System.out.println("000000000000000000000");
        packages("com.kingdee.controller.rest");
        register(MyContainerRequestFilter.class);
        register(MyContainerResponseFilter.class);
    }
}

3、设置接口

package com.kingdee.controller.rest;

import java.awt.List;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.Reader;
import java.util.Date;
import java.util.LinkedList;

import javax.jws.soap.SOAPBinding.Use;
import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletRequest;
import javax.websocket.server.PathParam;
import javax.ws.rs.BeanParam;
import javax.ws.rs.Consumes;
import javax.ws.rs.CookieParam;
import javax.ws.rs.DefaultValue;
import javax.ws.rs.FormParam;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.HttpHeaders;
