AJAX/Spring MVC-403在没有Spring安全性的情况下禁止出现错误

我正在尝试使用Spring MVC从我的web服务发出ajax请求:

package com.sid.webService;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import com.sid.dao.entity.Utilisateur;
import com.sid.metier.IMetierUtilisateur;

@Component
@RestController
@RequestMapping("/utilisateurs")
public class webServiceUtilisateur {
     @Autowired
     private IMetierUtilisateur mr;

     @RequestMapping(value="/addUser",method=RequestMethod.POST)
     public boolean addUser(@RequestBody Utilisateur u)
     {
        try
        {
            mr.ajouterUtilisateur(u);
            return true;
        }
        catch(Exception e)
        {
            return false;
        }
     }
  }

对于此AJAX请求:

$.ajax({
        url : "http://localhost:8080/utilisateurs/addUser",
        headers: { 
                 'Accept': 'application/json',
                 'Content-Type': 'application/json' 
                },
        type : "POST",
        data : user,
        dataType : "application/json"
}

这里的问题是用户正在登录,但没有正确的权限,真正的问题是我没有使用spring security,所以如何阻止权限,这是我对spring boot的配置:

spring.datasource.url=jdbc:mysql://localhost:3306/ekka-e-commerce
spring.datasource.username=root
spring.datasource.password=
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.hibernate.ddl-auto=create
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.enable_lazy_load_no_trans=true

春天jpa。财产。冬眠方言=组织。冬眠地方话MySQL5方言

• jquery。min.js:2个选项 http://localhost:8080/utilisateurs/addUser 403
• 无法加载 http://localhost:8080/utilisateurs/addUser :飞行前的响应具有无效的HTTP状态代码403。

这是我的pom。xml:

有人能告诉我这里出了什么问题吗,我是不是犯了一些错误?? 提前谢谢你。
