在Jhipster中將UserService注入SecurityConfiguration會導致Spring bean循環依賴

Question

我正在嘗試將jhipster 4應用程序配置為使用auth0進行身份驗證。 最初生成項目時，我選擇了JWT選項，該選項似乎可以正常工作並提供JWT支持。 我現在想做的是，通過讀取它們提供的JWT令牌並在首次看到新的auth0用戶名時創建一個用戶，來正確處理與auth0的集成。

為此，我計划將UserService注入jhipster提供的JWTFilter並在首次看到用戶名時創建一個新帳戶，如下所示：

private UserService userService;

public JWTFilter(TokenProvider tokenProvider, UserRepository userRepository, UserService userService) {
    this.tokenProvider = tokenProvider;
    this.userRepository = userRepository;
    this.userService = userService;
}

為此，我必須將UserService添加到JWTConfigurer的構造函數中， JWTConfigurer配置JWTFilter ：

package com.proj.security.jwt;

import com.proj.repository.UserRepository;
import com.proj.service.UserService;
import org.springframework.security.config.annotation.SecurityConfigurerAdapter;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.web.DefaultSecurityFilterChain;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;

public class JWTConfigurer extends SecurityConfigurerAdapter<DefaultSecurityFilterChain, HttpSecurity> {

    public static final String AUTHORIZATION_HEADER = "Authorization";

    public static final String AUTHORIZATION_TOKEN = "access_token";

    private TokenProvider tokenProvider;

    private UserRepository userRepository;

    private UserService userService;

    public JWTConfigurer(TokenProvider tokenProvider, UserRepository userRepository, UserService userService) {
        this.tokenProvider = tokenProvider;
        this.userRepository = userRepository;
        this.userService = userService;
    }

    @Override
    public void configure(HttpSecurity http) throws Exception {
        JWTFilter customFilter = new JWTFilter(tokenProvider, userRepository, userService);
        http.addFilterBefore(customFilter, UsernamePasswordAuthenticationFilter.class);
    }
}

最后，必須將其注入SecurityConfiguration的構造函數中

public SecurityConfiguration(AuthenticationManagerBuilder authenticationManagerBuilder, UserDetailsService userDetailsService,
        TokenProvider tokenProvider, CorsFilter corsFilter, UserRepository userRepository, UserService userService) {

    this.authenticationManagerBuilder = authenticationManagerBuilder;
    this.userDetailsService = userDetailsService;
    this.tokenProvider = tokenProvider;
    this.corsFilter = corsFilter;
    this.userRepository = userRepository;
    this.userService = userService;
}

並添加到JWTConfigurer bean

private JWTConfigurer securityConfigurerAdapter() {
    return new JWTConfigurer(tokenProvider, userRepository, userService);
}

但是，當我使用maven啟動應用程序時，出現以下錯誤：

2017-03-13 22:41:00.816  WARN 45420 --- [  restartedMain] o.s.boot.SpringApplication               : Error handling failed (Error creating bean with name 'delegatingApplicationListener' defined in class path resource [org/springframework/security/config/annotation/web/configuration/WebSecurityConfiguration.class]: BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.cache.annotation.ProxyCachingConfiguration': Initialization of bean failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'org.springframework.context.annotation.ConfigurationClassPostProcessor.importRegistry' available)

Description:

The dependencies of some of the beans in the application context form a cycle:

┌─────┐
|  securityConfiguration defined in file [/Users/user/work/proj/target/classes/com/proj/config/SecurityConfiguration.class]
↑     ↓
|  userService defined in file [/Users/user/work/proj/target/classes/com/proj/service/UserService.class]
└─────┘

UserService不會注入SecurityConfiguration ，因此我不確定如何解決此問題。 是否有其他方法可以解決此問題？

Answer 1

最后，我通過將SecurityConfiguration類的構造函數和setter注入混合來解決了這個問題，如下所示：

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    private final AuthenticationManagerBuilder authenticationManagerBuilder;

    private final UserDetailsService userDetailsService;

    private UserRepository userRepository;

    private final TokenProvider tokenProvider;

    private final CorsFilter corsFilter;

    private UserService userService;

    public SecurityConfiguration(AuthenticationManagerBuilder authenticationManagerBuilder, UserDetailsService userDetailsService,
            TokenProvider tokenProvider, CorsFilter corsFilter, UserRepository userRepository) {

        this.authenticationManagerBuilder = authenticationManagerBuilder;
        this.userDetailsService = userDetailsService;
        this.tokenProvider = tokenProvider;
        this.corsFilter = corsFilter;
        this.userRepository = userRepository;
    }

    @Autowired
    public void setUserService(UserService userService) {
        this.userService = userService;
    }
}

完成此操作后，我會看到使用正確的參數調用了構造函數，然后構造了UserService ，然后將其注入到SecurityConfiguration的設置器中，如我所願。
