1.1 Controller

文件名MyController，内容为：

@RestController@RequestMapping("/homepage")public class MyController {    @Autowired    MyService myService;    @GetMapping("/learnGet")    public String learnGet(){        return myService.learnGet();    }}

1.2 Service

文件名MyService，内容为：

@Service@EnableSchedulingpublic class MyService {    public String learnGet(){        Long timeLong = System.currentTimeMillis();        SimpleDateFormat timeFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); //设置格局        String timeString = timeFormat.format(timeLong);        return timeString;    }}

1.3 Application

在application.properties配置：

# 设置端口号server.port=8888

1.4 Postman

3 Post发送数据

我的项目地址：https://github.com/Snowstorm0...

须要留神，RestTemplate在postForObject时，用MultiValueMap，不可应用HashMap。

3.1 Controller

文件名MyController，内容为：

@RestController@RequestMapping("/homepage")public class MyController {    @Autowired    MyService myService;    @PostMapping("/postSend")    public Map<String, Object> postSend() {        return myService.postSend();    }}

3.2 Service

文件名MyService，内容为：

@Service@EnableSchedulingpublic class MyService {    @Resource    private RestTemplate restTemplate;    String URL = "http://localhost:8888/homepage/postReceiveByMap";    public Map<String, Object> postSend(){        Map<String, Object> sendData = new HashMap<>();        sendData.put("number", 3);        sendData.put("name", "张三");        ResponseEntity<ResponseResult> responseData = restTemplate.postForEntity(URL, sendData, ResponseResult.class);        Map<String, Object> returnData = new HashMap<>();        returnData.put("StatusCode:", responseData.getStatusCode());        returnData.put("Body:", responseData.getBody());        return returnData;    }}

3.3 ResponseResult

public class ResponseResult {    private int number;    private String name;    public ResponseResult(){    }    public int getNumber() {        return number;    }    public void setNumber(int number) {        this.number = number;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    @Override    public String toString() {        return "ResponseResult [number=" + number + ",name=" + name + "]";    }}

3.4 Config

@Configurationpublic class Config {    @Bean    public RestTemplate restTemplate(RestTemplateBuilder builder){        return builder.build();    }}
