如果http请求的内容类型为urlencoded，我如何让我的spring boot控制器读取对对象的http请求的主体？

import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestParam;
import import org.springframework.web.bind.annotation.RestController;

@RestController
public class MyController {

    @PostMapping("/example")
    public String handleRequest(@RequestParam("data") String data) {
        // 处理请求数据
        return "Received data: " + data;
    }
}

import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import import org.springframework.web.bind.annotation.RestController;

@RestController
public class MyController {

    @PostMapping("/example")
    public String handleRequest(@RequestBody MyRequestObject request) {
        // 处理请求数据
        return "Received data: " + request.getData();
    }
}

public class MyRequestObject {
    private String data;

    // getter和setter方法

    public String getData() {
        return data;
    }

    public void setData(String data) {
        this.data = data;
    }
}
