如何在Spring Servlet中接受JSON POST参数作为@RequestParam？

import org.springframework.web.bind.annotation.*;

@RestController
@RequestMapping("/example")
public class ExampleController {

    @PostMapping("/json")
    public String handleJsonRequest(@RequestBody MyJsonData jsonData) {
        // 处理接收到的JSON数据
        return "Received JSON data: " + jsonData.toString();
    }
}

public class MyJsonData {
    private String name;
    private int age;

    // 省略构造函数、getter和setter方法

    @Override
    public String toString() {
        return "Name: " + name + ", Age: " + age;
    }
}

{
  "name": "John",
  "age": 25
}
