#RequestBody getting parameters values null - spring

Question

I am developing a rest API, but it provides null with #RequestBody. I went through the answers on this platform but it didn't solve my problem. I am unable to find where the problem is. I want to verify the user by validating userEmail and userPassword but didn't succeed.
#RestController
#RequestMapping("user")
public class UserController {
#Autowired
private IUserService userService;
#GetMapping("validateUser")
public ResponseEntity<Boolean> validateUser(#RequestBody Users user) {
boolean validateStatus = userService.validateUser(user.getUserEmail(), user.getUserPassword());
if (validateStatus)
return new ResponseEntity<Boolean>(validateStatus, HttpStatus.OK);
else
return new ResponseEntity<Boolean>(validateStatus, HttpStatus.UNAUTHORIZED);
}
and pojo class as this:
package com.ravionics.user.entity;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name="users")
public class Users implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
#Column(name="user_Id")
private int userId;
#Column(name="user_Name")
private String userName;
#Column(name="user_Email")
private String userEmail;
#Column(name="user_Password")
private String userPassword;
public int getUserId() {
return userId;
}
public void setUserId(int userId) {
userId = userId;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
userName = userName;
}
public String getUserEmail() {
return userEmail;
}
public void setUserEmail(String userEmail) {
userEmail = userEmail;
}
public String getUserPassword() {
return userPassword;
}
public void setUserPassword(String userPassword) {
userPassword = userPassword;
}
}
