Spring Boot:如何将JSON对象添加到GET请求？

public class MyObject {
    @JsonProperty("name")
    private String name;

    @JsonProperty("age")
    private int age;

    // 省略getter和setter方法
}

@RestController
public class MyController {
    @GetMapping("/my-endpoint")
    public String handleRequest(@RequestParam("json") MyObject myObject) {
        // 处理接收到的JSON对象
        return "Success";
    }
}

RestTemplate restTemplate = new RestTemplate();

MyObject myObject = new MyObject();
myObject.setName("John");
myObject.setAge(25);

String url = "http://localhost:8080/my-endpoint?json=" + new ObjectMapper().writeValueAsString(myObject);

String response = restTemplate.getForObject(url, String.class);
