Spring lemon BeanCurrentlyInCreationException：创建bean时出错

我正在尝试按照这个 Spring 季 - 柠檬入门教程（https://naturalprogrammer.gitbooks.io/spring-lemon-getting-started/content/index.html），但我不能在某一点上走得更远 . 我创建了一个新的Spring启动项目（Spring boot），我能够添加spring lemon . 我没有做任何事情，只是遵循说明，但当我开始maven构建时，测试失败，出现以下错误：

org.springframework.beans.factory.BeanCreationException：创建名为'lmnDemoController'的bean时出错：注入自动连接的依赖项失败;嵌套异常是org.springframework.beans.factory.BeanCreationException：无法自动装配方法：public void com.naturalprogrammer.spring.lemon.LemonController.setLemonService（com.naturalprogrammer.spring.lemon.LemonService）;嵌套异常是org.springframework.beans.factory.BeanCurrentlyInCreationException：创建名为'lmnDemoService'的bean时出错：名称为'lmnDemoService'的Bean已作为循环引用的一部分注入其原始版本的其他bean [authenticationSuccessHandler]中，但是最终被包裹了 . 这意味着所述其他bean不使用bean的最终版本 . 这通常是过度渴望类型匹配的结果 - 例如，考虑使用'getBeanNamesOfType'并关闭'allowEagerInit'标志 .

我的 LmnDemoService.java 是：

package com.example;

import org.springframework.stereotype.Service;
import com.naturalprogrammer.spring.lemon.LemonService;

@Service
public class LmnDemoService extends LemonService<User, Long> { 
    @Override
    protected User newUser() {
        return new User();
    }
}

它只有教程所说的那些内容 . 我错过了什么？
