1、pow依赖

2、application.properties 几乎不用设置

server.port=8080

3、测试实体类

package cn.edu.jxnu.system.jersey;



/**

 * <p>

 * Title: City.java<／p>

 * <p>

 * Description: <／p>

 * <p>

 * Copyright: Copyright (c) 2018<／p>

 * <p>

 * School: jxnu<／p>

 * 

 * @author Mr.Li

 * @date 2018-2-4

 * @version 1.0

 */

public class City {

private Long id;

private String name;

private String code;



public Long getId() {

return id;

}



public void setId(Long id) {

this.id = id;

}



public String getName() {

return name;

}



public void setName(String name) {

this.name = name;

}



public String getCode() {

return code;

}



public void setCode(String code) {

this.code = code;

}



@Override

public String toString() {

return "City [id=" + id + ", name=" + name + ", code=" + code

+ ", getId()=" + getId() + ", getName()=" + getName()

+ ", getCode()=" + getCode() + ", getClass()=" + getClass()

+ ", hashCode()=" + hashCode() + ", toString()="

+ super.toString() + "]";

}



}

4、jersey配置

package cn.edu.jxnu.system.jersey;



import javax.ws.rs.ApplicationPath;



import org.glassfish.jersey.server.ResourceConfig;



/**

 * @时间 2018年2月4日15:30:16

 * @author Mr.Li

 * 

 */

@ApplicationPath("/restful")  顶级uri 即基本路径

public class JerseyConfig extends ResourceConfig {



public JerseyConfig() {

// 构造函数，在这里注册需要使用的内容，（过滤器，拦截器，API等）

// 注册类的方式

// register(Demo.class);

// register(RequestContextFilter.class);

// 注册包的方式

packages("cn.edu.jxnu.system.jersey");

}

}

5、jersey controller类似spring的controller

package cn.edu.jxnu.system.jersey;



import javax.ws.rs.GET;

import javax.ws.rs.Path;

import javax.ws.rs.Produces;

import javax.ws.rs.core.MediaType;

//这里jersey的bean是由自带容器管理，需要使用spring容器加@Component 测试了都可以

@Path("/jersey")

public class JerseyController {



// path注解指定路径,get注解指定访问方式,produces注解指定了返回值类型，这里返回JSON

@Path("/city")

@GET

@Produces(MediaType.APPLICATION_JSON)

public City get() {

City city = new City();

city.setId(10000L);

city.setName("beijing");

city.setCode("001");

System.out.println(city.toString());

return city;

}



}

6、主启动配置类

package cn.edu.jxnu.system;



import org.glassfish.jersey.servlet.ServletContainer;

import org.glassfish.jersey.servlet.ServletProperties;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.boot.web.servlet.ServletRegistrationBean;

import org.springframework.context.annotation.Bean;



import cn.edu.jxnu.system.jersey.JerseyConfig;



/**

 * @note 如果整合的时候自己加了数据库驱动pow,则由于自动配置，但是却没有使用数据库就会报错,解决办法是使用exclude

 *       排除数据库的自动配置，或者去除pow依赖

 * @author Mr.Li

 * 

 */

@SpringBootApplication

public class Application {

public static void main(String[] args) {

SpringApplication.run(Application.class, args);

}



@Bean

public ServletRegistrationBean jersetServlet() {

ServletRegistrationBean registration = new ServletRegistrationBean(

// 顶级uri 用来区分SpringMVC

new ServletContainer(), "/restful/*");

registration.addInitParameter(

ServletProperties.JAXRS_APPLICATION_CLASS,

JerseyConfig.class.getName());

return registration;

}

}

7、springmvc 测试controller【这个只是测试springboot中是可以同时使用jersey和springmvc的】

package cn.edu.jxnu.system.jersey;



import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;



/**

 * <p>

 * Title: SpringController.java<／p>

 * <p>

 * Description: <／p>

 * <p>

 * Copyright: Copyright (c) 2018<／p>

 * <p>

 * School: jxnu<／p>

 * 

 * @author Mr.Li

 * @date 2018-2-4

 * @version 1.0

 */

@RestController

@RequestMapping("/spring")

public class SpringController {


@RequestMapping("/city")

public City getCity() {


City city = new City();

city.setId(200000L);

city.setName("nanchang");

city.setCode("030");

System.out.println(city.toString());


return city;

}

}

由于前面jersey的restful url顶级前缀是restful,所以后面访问都需要加restful

如jersey：http://localhost:8080/restful/jersey/city

测试结果：

注：后台springmvc默认由DispatcherServlet处理并且在第一次处理的时候才会初始化DispatcherServlet 这个在日志中，

而restful开头的url才会被jersey的bean拦截

spring还是一样的：http://localhost:8080/spring/city

使用springboot，可使用springmvc构建restful,也可以使用jersey替代实现restful

两者可共存。如果springmvc顶级前缀是restful，这样不能实现共存，因为优先被jersey拦截，但是却不是jersey资源，将出现404

这里说的顶级前缀的去除ip:port后的最前url
