java - 在 AuthenticationProvider 中使用 Autowired 时出错

Question

我尝试在我的authenticationProvider 中使用 Autowiring 的对象，但出现错误。如果在类中不使用服务对象，没有问题，但当然我需要服务对象。

customAuthenticationprovider 类:

@Component
public class CustomAuthenticationProvider implements AuthenticationProvider {
@Autowired
private Service service;

@Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException {

    String name = authentication.getName();
    String password = authentication.getCredentials().toString();

    if (service.LoginCorrect(name, password)) {

        // use the credentials
        // and authenticate against the third-party system
        List<GrantedAuthority> grantedAuths = new ArrayList<>();
        grantedAuths.add(new SimpleGrantedAuthority(service.getPerson(name).getRole().role()));
        return new UsernamePasswordAuthenticationToken(
                name, password, grantedAuths);
    } else {
        return null;
    }

}

@Override
public boolean supports(Class<?> authentication) {
    return authentication.equals(UsernamePasswordAuthenticationToken.class);
}}

使用自定义提供程序的类:

@Configuration
@EnableWebSecurity
@ComponentScan("view.controller")
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

@Autowired
private CustomAuthenticationProvider authenticationProvider;

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

    http
            .authorizeRequests()
            .antMatchers("/register/**").permitAll()
            .anyRequest().authenticated()
            .and()
            .formLogin()
            .loginPage("/login").permitAll();
}

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

Bean 的创建:

@Configuration
class ApplicationConfig extends WebMvcConfigurerAdapter {

@Bean(destroyMethod = "close")
public Service service() {
    return new Service("JPADatabase");
}
}

安全初始化:

public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[]{ApplicationConfig.class, WebSecurityConfig.class};
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[]{DispatcherServletConfig.class};
    }

    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }

}

错误消息:

Warning: Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'webSecurityConfig': Unsatisfied dependency expressed through field 'authenticationProvider'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'customAuthenticationProvider' defined in file [D:\Users\neuts\Documents\NetBeansProjects\project-ip-vincentneuts\spring-mvc-kopie\target\r0621919\WEB-INF\classes\view\controller\CustomAuthenticationProvider.class]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [view.controller.CustomAuthenticationProvider]: Constructor threw exception; nested exception is java.lang.RuntimeException: Uncompilable source code - cannot find symbol symbol: class Autowired location: class view.controller.CustomAuthenticationProvider Severe: Context initialization failed org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'webSecurityConfig': Unsatisfied dependency expressed through field 'authenticationProvider'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'customAuthenticationProvider' defined in file [D:\Users\neuts\Documents\NetBeansProjects\project-ip-vincentneuts\spring-mvc-kopie\target\r0621919\WEB-INF\classes\view\controller\CustomAuthenticationProvider.class]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [view.controller.CustomAuthenticationProvider]: Constructor threw exception; nested exception is java.lang.RuntimeException: Uncompilable source code - cannot find symbol symbol: class Autowired location: class view.controller.CustomAuthenticationProvider

编辑:它仅在第一次运行时有效。 (重新启动我的 glassfish 服务器后)

Answer 1

从异常java.lang.RuntimeException: Uncompilable source code来看，很明显这个错误是netbeans特有的。我猜想 netbeans 正在使用两个不同的“类文件”数据源，以便它可以解析构建上的所有符号，但运行时类路径和编辑器正在使用不同的东西。

如果您使用 maven/gradle，请尝试使用它而不是 IDE 来构建和运行。或者尝试清理 netbeans 缓存。
