启动类

@SpringBootApplication
public class JerseyDemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(JerseyDemoApplication.class, args);
    }


    // 注册 资源 MyResource
    @Bean
    public ResourceConfig resourceConfig() {
        ResourceConfig resourceConfig = new ResourceConfig();
        resourceConfig.register(MyResource.class);
        return resourceConfig;
    }

}

资源类

//@Component 非必须
@Singleton//单例
@Path("/resource")//设置路径
public class MyResource {

    @GET
    //返回json 数据
    @Produces(MediaType.APPLICATION_JSON)
    public Map<String,String> hello() {
        Map<String, String> result = new HashMap<>();
        result.put("username","test");
        result.put("password","test");
        return result;
    }
