java - 如何通过 Spring Rest 模板使用原始数据进行发布请求

Question

有人可以告诉我如何发送带有原始数据参数的 POST 请求，如下图所示

我尝试了以下代码，但它不起作用

HttpHeaders headers = new HttpHeaders();
                headers.setContentType(MediaType.APPLICATION_JSON);
            JsonObject properties = new JsonObject();
            MultiValueMap<String, String> params = new LinkedMultiValueMap<>();         
            try {

                properties.addProperty("app_id", appId);
                properties.addProperty("identity","TestAPI");
                properties.addProperty("event", "TestCompleted");
                properties.addProperty("testType", t.getTestType());
                properties.addProperty("testName",t.getTestName());
                properties.addProperty("chapter","");
                properties.addProperty("module","");
                properties.addProperty("pattern",t.getTestPattern());
                HttpEntity<String> request = new HttpEntity<>(
                        properties.toString(), headers);
               // params.add("properties", properties.toString());
                 restTemplate.postForObject(url, request, String.class);

有人可以帮忙吗？

试试这个:

@RestController
public class SampleController { 
    @RequestMapping("/req")
    public String performReqest(){
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);        
        JsonObject properties = new JsonObject();
        properties.addProperty("no", "123");
        properties.addProperty("name", "stackoverflow");
        HttpEntity<String> request = new HttpEntity<>(properties.toString(), headers);
        RestTemplate restTemplate = new RestTemplate();
        String response = restTemplate.postForObject("http://localhost:4040/student", request, String.class);
        return "Response from Server is : "+response;       
    }

    @RequestMapping("/student")
    public String consumeStudent(@RequestBody Student student){
        System.out.println(student);
        return "Hello.."+student.name;
    }   
}

class Student{
    public int no;
    public String name; 
    public Map<String,String> properties;   
}

不要忘记移动 Student 类，并使用 require getter 和 setter 将所有字段更改为 private 。 以上代码仅用于演示目的。
