Java SpringBoot UserDetailsService loadUserByUsername方法从未使用自定义WebSecurity配置适配器调用

以下是本视频中的教程：

我的密码是7:30。无论出于何种原因，我似乎无法让

securityconfig.java

类识别名为

myuserdetailssservice.java

的自定义UserDetailsService类

预期的行为是，当我转到我在

HelloResource.Java

类中指定的/hello端点时，应该生成一个登录页面。我应该能够使用

loadUserByUsername

方法的硬编码返回用户名和密码为“foo”的用户值登录到网页

不管我做了什么更改，似乎总是没有调用

loadUserByUsername

方法（我已经用断点/打印语句证明了这一点）。这让我相信可能有一些组件扫描问题，vut我还没有看到任何工作

我已经在以下链接中尝试了解决方案： 再加上一些。以下是我的相关档案：

JWTMain.java

package com.JWTTest;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@ComponentScan("{com.JWTTest}")
public class JwtMain {

    public static void main(String[] args) {
        SpringApplication.run(JwtMain.class, args);
    }
}

HelloResource.java

package com.JWTTest;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HelloResource {

    @RequestMapping("/hello")
    public String HelloString(){
        return "Hello";
    }

}

MyUserDetailsService.java

package com.JWTTest;

import org.jvnet.hk2.annotations.Service;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;

import java.util.ArrayList;

@Service
public class MyUserDetailsService implements UserDetailsService {

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        return new User("foo", "foo", true, true, true, true, new ArrayList<>());
    }
}

除此之外，我对正在发生的事情一无所知。让我知道，谢谢

解决方案：

@SpringBootApplication
@ComponentScan 

应该是主要的方法。只要@EnableWebSecurity在SecurityConfigure类中，Springboot就知道有人试图覆盖Springboot提供的安全类。我的主要方法的问题是Springboot没有正确扫描我的类

我还了解到，通过将此注释置于主类之上，可以排除Springboot提供的安全类：

@SpringBootApplication(exclude = { SecurityAutoConfiguration.class })

---

在

MyUserDetailsService.java

中，您正在导入

org.jvnet.hk2.annotations.Service

，而正确的是

org.springframework.stereotype.Service

@SpringBootApplication(exclude = { SecurityAutoConfiguration.class })
