如何在Spring Boot Controller中读取post数据？

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

@RestController
public class MyController {

    @PostMapping("/data")
    public String processData(@RequestBody String data) {
        // 处理接收到的POST数据
        return "Received data: " + data;
    }
}

@RestController
public class MyController {

    @PostMapping("/data")
    public String processData(@RequestBody MyDataObject data) {
        // 处理接收到的POST数据
        return "Received data: " + data.toString();
    }
}

public class MyDataObject {
    private String name;
    private int age;
    // 其他属性和方法

    // getter和setter方法
}
