自动接线不适用于Spring Boot中的自定义UserDetailsS​​ervice [英] Autowire doesn't work for custom UserDetailsService in Spring Boot

问题描述

spring boot应用程序启动，tomcat运行，然后在最终死亡之前引发错误.

The spring boot apps starts up, tomcat runs, and then it throws an error before finally dying.

运行我的应用程序会给我这个Autowired错误:

Running my app gives me this Autowired error:

2016-07-29 02:18:24.737 ERROR 44715 --- [  restartedMain] o.s.boot.SpringApplication               : Application startup failed

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'webSecurityConfig': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private myapp.MyUserDetailsService myapp.WebSecurityConfig.userDetailsService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [myapp.MyUserDetailsService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

我的安全性配置:

My Security configuration:

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
        http
        .authorizeRequests()
        .antMatchers("/", "/register").permitAll()
        .anyRequest().authenticated()
        .and()
        .formLogin()
        .loginPage("/")
        .permitAll()
        .and()
        .logout()
        .permitAll();
}

@Autowired
private MyUserDetailsService userDetailsService;

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService);
}

}

MyUserDetails:

MyUserDetails:

@Service
@Transactional
public class MyUserDetailsService implements UserDetailsService {

@Autowired
private UserRepository userRepository;


public MyUserDetailsService() {
        super();
}

@Override
public UserDetails loadUserByUsername(String userName)
throws UsernameNotFoundException {
        User user = userRepository.findByUserName(userName);
        if (user == null) {
                return null;
        }
        List<GrantedAuthority> auth = AuthorityUtils
                                      .commaSeparatedStringToAuthorityList("ROLE_USER");
        String password = user.getPassword();
        return new org.springframework.security.core.userdetails.User(userName, password,
                                                                      auth);
}

推荐答案

我在提交3b9a6a2e时尝试了您的项目，但错误实际上有所不同:

I've tried your project at commit 3b9a6a2e, and the error is actually different:

org.springframework.beans.factory.BeanCreationException:创建名称为'webSecurityConfig'的bean时出错:自动连接依赖项的注入失败；嵌套的异常是org.springframework.beans.factory.BeanCreationException:无法自动连线字段:private myapp.MyUserDetailsS​​ervice myapp.WebSecurityConfig.userDetailsS​​ervice;嵌套的异常是java.lang.IllegalArgumentException:无法将myapp.MyUserDetailsS​​ervice字段myapp.WebSecurityConfig.userDetailsS​​ervice设置为com.sun.proxy.$ Proxy80

哪个让您的问题重复了 Spring无法创建bean .解决方案:替换

Which makes your question a duplicate of Spring can't create beans. Solution: replace

@Autowired
private MyUserDetailsService userDetailsService;

使用

@Autowired
private UserDetailsService userDetailsService;

---

您的解决方案(删除@Transactional)之所以有效，是因为没有@Transactional，Spring没有理由将MyUserDetailsService包装在代理中.

---

Your solution (removing @Transactional) works because without @Transactional there is no reason for Spring to wrap MyUserDetailsService in a proxy.
