spring security jdbc抛出空指针

我正在尝试将Spring-Security 4.0.0.M1与Spring-Boot 1.0.2.RELEASE与H2和Spring-data-jpa.1.5.2一起使用。我能够在SecurityConfig.configure方法中创建一个用户,但是当我将其解压缩到自己的类时,我得到一个nullpointer异常。我进入JdbcDaoSupport.java并看到getJdbcTemplate()返回null jdbcTemplate。

这是我的配置:

@Configuration
@EnableWebMvcSecurity
@EnableGlobalMethodSecurity(prePostEnabled = false)
public class SecurityConfig extends WebSecurityConfigurerAdapter { 
    @Autowired
    private DataSource dataSource;

    @Autowired
    UserService userService;

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http
                .authorizeRequests()
                .antMatchers( "/resources/**" ).permitAll()
                .antMatchers( "/css/**" ).permitAll();

        http
                .formLogin().failureUrl( "/login?error" )
                .defaultSuccessUrl( "/" )
                .loginPage( "/login" )
                .permitAll()
                .and()
                .logout().logoutRequestMatcher( new AntPathRequestMatcher( "/logout" ) ).logoutSuccessUrl( "/login" )
                .permitAll();

        http
                .authorizeRequests().anyRequest().authenticated();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
                .jdbcAuthentication()
                .dataSource( dataSource );
    }

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

我的主配置类定义了数据源,我知道它可以工作:

@Bean
public DataSource dataSource() {
    return new EmbeddedDatabaseBuilder().setType( EmbeddedDatabaseType.H2 ).setName( "ofac" )
            .addScript( "classpath:h2.sql" ).build();
}

我有一个用户服务,用于添加用户:

@Component
public class UserService {

    @Autowired
    private AuthenticationManagerBuilder authenticationManagerBuilder;

    @Autowired
    private javax.sql.DataSource dataSource;

    @PostConstruct()
    public void initUsers() throws Exception {
        addNewUser( "admin", "password", "ADMIN" );
    }

     public void addNewUser(String username, String plainPassword, String role) {

    List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
    authorities.add( new SimpleGrantedAuthority( role ) );
    PasswordEncoder encoder = new BCryptPasswordEncoder();

    UserDetails hashedUser = new User( username, encoder.encode( plainPassword ), authorities );

    JdbcUserDetailsManager userDetailsService = (JdbcUserDetailsManager) authenticationManagerBuilder.getDefaultUserDetailsService();
    try {
        if ( userDetailsService.userExists( hashedUser.getUsername() ) ) {
            userDetailsService.deleteUser( hashedUser.getUsername() );
        }
        // and finally, create the user
        userDetailsService.createUser( hashedUser );
    } catch ( Exception ex ) {
        ex.printStackTrace();
    }
 }
}

我在UserService.initUsers上有一个断点,当行:

authenticationManagerBuilder.jdbcAuthentication().getUserDetailsService().userExists( hashedUser.getUsername() ) 
调用

,我可以看到authenticationManagerBuilder.jdbcAuthentication()返回null jdbcTemplate。所有在线文档似乎都表明这可行,但它似乎并没有像我期待的那样连接所有内容。

有谁知道可能出错了什么?

更新: 我改变了项目,所以我不再拥有SecurityConfig,而是拥有:

@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
@Configuration
public class ApplicationSecurity extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .antMatchers( "/resources/**" ).permitAll()
                .antMatchers( "/css/**" ).permitAll();

        http
                .formLogin().failureUrl( "/login?error" )
                .defaultSuccessUrl( "/" )
                .loginPage( "/login" )
                .permitAll()
                .and()
                .logout().logoutRequestMatcher( new AntPathRequestMatcher( "/logout" ) ).logoutSuccessUrl( "/login" )
                .permitAll();

        http
                .authorizeRequests().anyRequest().authenticated();
    }
}

和a:

@Order(Ordered.HIGHEST_PRECEDENCE)
@Configuration
public class AuthenticationSecurity extends GlobalAuthenticationConfigurerAdapter {


    @Autowired
    private DataSource dataSource;

    @Override
    public void init(AuthenticationManagerBuilder auth) throws Exception {
        auth
                .jdbcAuthentication()
                .dataSource( dataSource );
    }
}

但在我的UserService中,我在这里得到一个null userDetailsS​​ervice:

JdbcUserDetailsManager userDetailsService = (JdbcUserDetailsManager) authenticationManagerBuilder.getDefaultUserDetailsService();

我还没想出如何在启动后实际创建用户。我认为这是使用UserDetailsS​​ervice,但这不提供功能。我想可能需要一个JdbcUserDetailsManager,但到目前为止我还无法连接一个有效的。

答案 0 :(得分:0)

注入对象时,AuthenticationManagerBuilder可能尚未完全初始化。 Spring Security使用各种标记来指示初始化顺序,例如,您可以尝试像the method security sample一样扩展GlobalAuthenticationConfigurerAdapter
