SpringBoot 踩坑之整合jersey client

1.在pom引用Jersey client jar

                
			org.glassfish.jersey.core
			jersey-client
			2.22.1
		


		
			org.glassfish.jersey.media
			jersey-media-json-jackson
			2.22.1
		

2.因springboot eureka 管理容器与客户端交互的http协议是基于Jersey 1.x  而Jersey已经到Jersey 2.x了，eureka不支持。因而采用在eureka剔除jersey2.x不支持的jar

            
			org.springframework.cloud
			spring-cloud-starter-eureka
			
				
					javax.ws.rs
					jsr311-api
				
			
		

3.创建jerseyclient工具类RestClientUtils

import java.util.Map;
import java.util.Set;

import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.Entity;
import javax.ws.rs.client.Invocation.Builder;
import javax.ws.rs.client.WebTarget;
import javax.ws.rs.core.MediaType;

public class RestClientUtils {
	
	
	private static WebTarget target = null;// ClientBuilder.newClient().target(ApplicationConstant.REST_URL_DOCTOR_REMOTE);
	
	public static  T post(String url, String path, Object param, Map queryParam, Class rtnClass){
		if (url != null) {
			target = ClientBuilder.newClient().target(url);
		}
		WebTarget pathTarget = target.path(path);
		
		Set keys = queryParam.keySet();
		for (String string : keys) {
			pathTarget = pathTarget.queryParam(string, queryParam.get(string));
		}
		//logger.info(pathTarget.getUri().toString());
		return pathTarget.request(MediaType.APPLICATION_JSON_TYPE).post(Entity.entity(param, MediaType.APPLICATION_JSON_TYPE), rtnClass);
	}
	
	public static  T headerPost(String url, String path, Object param, Map queryParam, Class rtnClass,Map headerParam){
		if (url != null) {
			target = ClientBuilder.newClient().target(url);
		}
		WebTarget pathTarget = target.path(path);
		
		Set keys = queryParam.keySet();
		for (String string : keys) {
			pathTarget = pathTarget.queryParam(string, queryParam.get(string));
		}
		Builder request = pathTarget.request(MediaType.APPLICATION_JSON_TYPE);
		keys = headerParam.keySet();
		for (String string : keys) {
			request = request.header(string, headerParam.get(string));
		}
		//logger.info(pathTarget.getUri().toString());
		return request.post(Entity.entity(param, MediaType.APPLICATION_JSON_TYPE), rtnClass);
	}
	
	public static  T post(String url, String path, Object param, Class rtnClass){
		if (url != null) {
			target = ClientBuilder.newClient().target(url);
		}
		WebTarget pathTarget = target.path(path);
		return pathTarget.request(MediaType.APPLICATION_JSON_TYPE)
				.post(Entity.entity(param, MediaType.APPLICATION_JSON_TYPE), rtnClass);
	}

	public static String postText(String url, String path, Object param){
		if (url != null) {
			target = ClientBuilder.newClient().target(url);
		}
		WebTarget pathTarget = target.path(path);
//		pathTarget.request("").post()
		return pathTarget.request(MediaType.TEXT_PLAIN)
				.post(Entity.entity(param, MediaType.APPLICATION_JSON_TYPE),String.class);
	}
	
	
	
	public static  T get(String url, String path, Map params, Class rtnClass){
		if (url != null) {
			target = ClientBuilder.newClient().target(url);
		}
		WebTarget pathTarget = target.path(path);
		Set keys = params.keySet();
		for (String string : keys) {
			pathTarget = pathTarget.queryParam(string, params.get(string));
		}
		
		return pathTarget.request().get(rtnClass);
	}
	
	
	public static  T delete(String url, String path, Map params, Class rtnClass){
		if (url != null) {
			target = ClientBuilder.newClient().target(url);
		}
		WebTarget pathTarget = target.path(path);
		Set keys = params.keySet();
		for (String string : keys) {
			pathTarget = pathTarget.queryParam(string, params.get(string));
		}
		
		return pathTarget.request().delete(rtnClass);
	}
	
	public static  T put(String url, String path, Object param, Map queryParam, Class rtnClass){
		if (url != null) {
			target = ClientBuilder.newClient().target(url);
		}
		WebTarget pathTarget = target.path(path);
		
		Set keys = queryParam.keySet();
		for (String string : keys) {
			pathTarget = pathTarget.queryParam(string, queryParam.get(string));
		}
		return pathTarget.request(MediaType.APPLICATION_JSON_TYPE)
				.put(Entity.entity(param, MediaType.APPLICATION_JSON_TYPE), rtnClass);
	}

	
	public static  T get(String url,String path,Class rtnClass){
		if (url != null) {
			target = ClientBuilder.newClient().target(url);
		}
		WebTarget pathTarget = target.path(path);
		
		return pathTarget.request().get(rtnClass);
	}
