Spring Security身份验证提供程序java配置

Question

我实现了自己的UserDetailsService。我正在Java中配置Spring Security性。我如何创建默认身份验证提供程序与我的自定义用户服务详细信息服务和一些密码编码器？

public class UserDetailsServiceImpl implements UserDetailsService 

@Bean
public UserDetailsServiceImpl userDetailsService(){
    return new UserDetailsServiceImpl();
}


@Bean
public AuthenticationManager authenticationManager() throws Exception{
    return auth.build();
}

@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {

    BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
    auth.userDetailsService(userDetailsService()).passwordEncoder(passwordEncoder);

但是，当我运行这段代码时，我有异常：

Caused by: java.lang.IllegalArgumentException: Can not set com.xxx.UserDetailsServiceImpl field com.....MyAuthenticationProvider.service to com.sun.proxy.$Proxy59
    at sun.reflect.UnsafeFieldAccessorImpl.throwSetIllegalArgumentException(UnsafeFieldAccessorImpl.java:164)

我想我做错了什么

Answer 1

错，您应该按照以下方式实现您的服务：

@Service("authService")
public class AuthService implements UserDetailsService {

之后，请在您的配置中使用它：

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

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

不应使用new关键字实例化bean。
