微服务：简单服务提供者与服务消费者

1.服务提供者：被其他微服务调用的微服务

2.服务消费者：调用的其他微服务的微服务

【服务提供】provide：8080端口

@RestController
@RequestMapping("sysUserWeb2")
public class SysUserWeb2 {

    @Resource
    private  SysUserService2 SysUserService2;

    @RequestMapping("/getAll")
    @ResponseBody
    public List<SysUser>findAll2(){
        return SysUserService2.findAll2();
    }

    @RequestMapping("/findSysUserName")
    @ResponseBody
    public SysUser findSysUserName(String name){
        return SysUserService2.findSysUserName(name);
    }

}

【服务消费】customer ：8081端口

@RestController
public class Controller {

    @Autowired
    private RestTemplate restTemplate;

    @GetMapping("/findSysUserName/{name}")
    public SysUser  findSysUserName(@PathVariable String name){
        return restTemplate.getForObject("http://localhost:8080/sysUserWeb2/findSysUserName?name="+name, 

SysUser.class);
    }
}

@SpringBootApplication
public class SpringBooTemplateApplication {

    @Bean
    public RestTemplate  restTemplate(){
        return new RestTemplate();
    }

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

@GetMapping("/findSysUserName/{name}")

描述：出现于spring4.3之后，源码中效果相当于：@RequestMapping(value="findSysUserName",method=RequestMethod.GET)
