jersey 是基于Java的一個輕量級RESTful風(fēng)格的Web Services框架。以下我基于IDEA實(shí)現(xiàn)Restful完整Demo。

1.創(chuàng)建maven-web工程，后面就是正常的maven工程創(chuàng)建流程。

2.添加Jersey框架的maven文件。

3.Restful接口定義。

package com.restful.service;

import com.fasterxml.jackson.core.JsonProcessingException;

import com.fasterxml.jackson.databind.ObjectMapper;

import com.restful.entity.PersonEntity;

import javax.ws.rs.*;

import javax.ws.rs.core.MediaType;

import java.io.IOException;

import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;

import java.util.Map;

/**

* Created by XuHui on 2017/8/2.

*/

@Path("/JerseyService")

public class JerseyService {

private static Map map = new HashMap();

@GET

@Path("/getAllResource")

@Produces(MediaType.APPLICATION_JSON)

public String getAllResource() throws JsonProcessingException {

List list = new ArrayList();

for (PersonEntity entity : map.values()) {

list.add(entity);

}

ObjectMapper mapper = new ObjectMapper();

return mapper.writeValueAsString(list);

}

@GET

@Path("/getResourceById/{id}")

@Produces(MediaType.APPLICATION_JSON)

public String getResource(@PathParam("id") String id) throws JsonProcessingException {

ObjectMapper mapper = new ObjectMapper();

return mapper.writeValueAsString(map.get(id));

}

@POST

@Path("/addResource/{person}")

@Consumes({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})

@Produces(MediaType.APPLICATION_JSON)

public String addResource(String person) throws IOException {

ObjectMapper mapper = new ObjectMapper();

PersonEntity entity = mapper.readValue(person, PersonEntity.class);

map.put(entity.getId(), entity);

return mapper.writeValueAsString(entity);

}

@GET

@Path("/getRandomResource")

@Produces(MediaType.APPLICATION_JSON)

public String getRandomResource() throws JsonProcessingException {

ObjectMapper mapper = new ObjectMapper();

PersonEntity entity = new PersonEntity("NO1", "Joker", "http:///");

return mapper.writeValueAsString(entity);

}

}

PersonEntity實(shí)體類實(shí)現(xiàn)。

package com.restful.entity;

/**

* Created by XuHui on 2017/8/2.

*/

public class PersonEntity {

private String id;

private String name;

private String addr;

public PersonEntity() {

}

public PersonEntity(String id, String name, String addr) {

this.id = id;

this.name = name;

this.addr = addr;

}

public String getId() {

return id;

}

public void setId(String id) {

this.id = id;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getAddr() {

return addr;

}

public void setAddr(String addr) {

this.addr = addr;

}

@Override

public String toString() {

return "PersonEntity{" +

"id='" + id + '\'' +

", name='" + name + '\'' +

", addr='" + addr + '\'' +

'}';

}

}

4.web.xml配置。

5.搭建本地tomcat

6.運(yùn)行結(jié)果、http://localhost:8080/jerseyDemo/rest/application.wadl是所有對外接口的調(diào)用方法。使用postman來看看這個接口是怎么調(diào)用的吧。
