Java Spring boot:delegateBuilder在自定义UserDetailsService中的autowiring authenticationManager上不能为null

您好，我是spring boot新手，正在尝试将安全性实现到我的rest API中

我使用的是SpringBoot2.0.7.0版本

我已将我的Web安全配置如下

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Resource(name = "userService")
    private UserDetailsService userDetailsService;

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
       return super.authenticationManagerBean();
    }

    @Autowired
    public void globalUserDetails(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService)
            .passwordEncoder(encoder());
    }

    @Bean
    public JwtAuthenticationFilter authenticationTokenFilterBean() throws Exception {
        return new JwtAuthenticationFilter();
    }
    @Bean
    public PasswordEncoder encoder(){
         PasswordEncoder encoder = new CustomPasswordEncoder(); 
         return encoder;
    }
    ....
   }

我已经添加了资源名，这样我就可以指向自定义userDetailsService

我已经尝试通过come配置authenticationmanagerbean，并通过限定符authenticationmanagerbean指向该Bean，但错误仍然相同

出于安全考虑，我的pom.xml看起来像

......
<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-security</artifactId>
</dependency>
......

以下是错误日志。我只提供了邮件错误

为了更好地帮助您，最好指出您在实现JWT mechansim时遵循的参考

从概念上讲，这部分源代码是错误的：

@Override
public String login(LoginUser user) {
       // valid user if it exits then do the following

        authenticationManager.authenticate(
            new UsernamePasswordAuthenticationToken(user.getUsername(), user.getPassword()));

       //generate the token and do other process.
}

看看下面的修改是否能帮助您

1）考虑使用java配置文件在一个分离的配置类< /P>中声明bean

@Configuration
public class ServiceConfig{   
   @Bean
   protected UserDAOService daoService()
   {
      return new UserDAOServiceImpl();
   }
   @Bean
   protected UserDetailsService userDetailService( UserDAOService dao )
   {
      return new UserServiceImpl( dao );
   }
   @Bean
   public PasswordEncoder encoder(){
     PasswordEncoder encoder = new CustomPasswordEncoder(); 
     return encoder;
   }
   @Bean
   public JwtAuthenticationFilter authenticationTokenFilterBean() throws Exception{                           {
    return new JwtAuthenticationFilter();
   }
}

2） 修改您的Web安全配置

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private UserDetailsService userDetailsService;

    @Autowired
    private PasswordEncoder passwordEncoder;


    @Override
    protected void configure( AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService( userDetailsService ).passwordEncoder( passwordEncoder );
    }

}

您可能有一个循环bean依赖项，只需删除“authenticationManagerBean”方法并重试。我认为这个bean不需要显式创建（我做过类似的事情，但没有显式声明）。@Spara我检查了我的整个项目，没有循环beandependency@sampathpremarathna在发布之前，我尝试删除authenticationManagerBean的bean配置，因为我在userservice-implementation类中自动连接，所以该类说bean不是found@Saikrishna哦，我还没有为JWT这样做，但对我来说，在WebSecurityConfig上配置全局实现确实有效，对我来说，不需要“UserServiceImpl”上的登录方法。这在我的案例中对我有所帮助：我将尝试这一点。感谢这项工作，但我正在web安全配置中配置一个更改AuthenticationManager，因为它是extends WebSecurity ConfigureAdapter，我们正在覆盖它

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private UserDetailsService userDetailsService;

    @Autowired
    private PasswordEncoder passwordEncoder;


    @Override
    protected void configure( AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService( userDetailsService ).passwordEncoder( passwordEncoder );
    }

}
