java - 如何将数据传递给 Springboot 后端点

Question

我这里有货，我需要帮助。
我正在编写一个端点以从请求正文中获取数据。
我的 Spring 应用程序返回错误。

/* CreteStudentRequest Model */
public class CreateStudentRequest {
    String first_name;
    String last_name; 
    String email;
}

/* Post endpoint */
@PostMapping("/create")
@ResponseBody
public CreateStudentRequest addStudent(@RequestBody CreateStudentRequest csr ) {

   System.out.println("This is Cool... add Student post endpoint"); 

   //return studentservice.createStudent("LOT","2ray","[e-mail]");

   return csr;   
}

/* Error I get */
