服务2-moduleSecond

例子：

@CrossOrigin
@RestController
@RequestMapping("/hello")
public class HelloController {

    @GetMapping("/get")
    public String get(){
        System.out.println("moduleSecond log........");
        return "get ... moduleSecond_haha";
    }


    @PostMapping("/post")
    public String post(@RequestBody Map<String,String> map){
        System.out.println("moduleSecond map is "+map);
        return "post ... moduleSecond_haha";
    }
}

服务1-moduleOne

1、远程调用的配置：

@Configuration
public class RestTemplateConfiguration {

//    @LoadBalanced
    @Bean
    public RestTemplate restTemplate() {
        RestTemplate restTemplate = new RestTemplate();
        MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
        converter.setSupportedMediaTypes(Collections.singletonList(MediaType.TEXT_PLAIN));
        restTemplate.getMessageConverters().add(converter);
        return restTemplate;
    }
}

public class HelloController {

    @GetMapping("/get")

    }

    @PostMapping("/post")
    public String post(@RequestBody Map<String, String> map) {
        System.out.println("moduleOne map is " + map);
        return map.toString();
    }

    @Resource

        String object = restTemplate.postForObject(otherServerUrl + "/post", map, String.class);
        System.out.println("object is " + object);
        return object;


    }

    private static final String mySelfUrl = "http://127.0.0.1:8081/xinqidev_moduleOne/hello";

    @GetMapping("/testMySelfGetMethod")

        String object = restTemplate.postForObject(mySelfUrl + "/post", map, String.class);
        System.out.println("object is " + object);
