Debug RestTemplate Post request
提问by Learn More
I am trying to POSTto a REST-APIusing RestTemplatein Spring.
Here is the code I am using:
我想POST以一个REST-API使用RestTemplate在Spring。这是我正在使用的代码：
//Code to Post data using Rest Template
List<UserVO> userList = getUsers();
RestRequestVO submitRequestData = new RestRequestVO();
submitRequestData.setAction("update");
submitRequestData.setType("user");
submitRequestData.setItems(items);
ResponseEntity<String> resposne = restTemplate.postForEntity(putUserUrl, submitRequestData, String.class);
String message = resposne.getBody();
//The structure of class
public class RestRequestVO {
private String action;
private String type;
private List<UserVO> items;
//Setters and Getters
}
//Expected JSON
{
"action"="update",
"type"="user",
"items"=[
{ //user1 }, {//user2} ....
]
}
I need to debug this properly and see what is the exact JSON being sent to the REST server by restTemplate.postForEntity(putUserUrl, submitRequestData, String.class);line.
我需要正确调试它并查看restTemplate.postForEntity(putUserUrl, submitRequestData, String.class);逐行发送到 REST 服务器的确切 JSON 是什么。
I am using Eclipse. I have tried debugging code line by line.
I have also tried setting log-level to Debug.
我正在使用Eclipse. 我试过逐行调试代码。我也尝试将日志级别设置为Debug.

Below is my log4j.xml, I can not see any http logs related to REST Template. Please let me know if I have done some mistake.
下面是我的log4j.xml，我看不到任何与 REST 模板相关的 http 日志。如果我做错了什么，请告诉我。

I intend to print JSON which is being created from POJO before it is sent to REST POST URL.
我打算打印从 POJO 创建的 JSON，然后再将其发送到 REST POST URL。

You can set breakpoint in AbstractHttpMessageConverterat the end of the public final void write(final T t, MediaType contentType, HttpOutputMessage outputMessage)method, and evaluate outputMessage.getBody()
您可以AbstractHttpMessageConverter在public final void write(final T t, MediaType contentType, HttpOutputMessage outputMessage)方法的末尾设置断点，并评估outputMessage.getBody()
