How does spring accept a JSON object?

In Spring, you can use the @RequestBody annotation to receive a JSON object.

Firstly, add the @RequestBody annotation in your controller method to specify the JSON object you want to receive. Spring will then automatically convert the passed JSON into a Java object.

The sample code is listed below:

@PostMapping("/example")
public void exampleMethod(@RequestBody YourModel yourModel) {
    // 执行相关逻辑
}

In the example above, YourModel is a Java class that you define to represent the structure of the JSON object that you want to receive. Spring will convert the passed JSON data into an instance of YourModel.

Please note that in order for Spring to correctly convert JSON into Java objects, you need to include the appropriate JSON converter in your project. You can use libraries like Jackson or Gson for JSON conversion.
