为什么UserDetailsS​​ervice在Spring Boot应用程序中返回null？

[英]Why does UserDetailsService return null in Spring Boot app?

问题描述

一个简单的spring boot应用程序具有自定义的UserDetailsS​​ervice。 Spring Boot Controller由AngularJS应用程序调用，并且来自AngularJS应用程序的身份验证请求以/user url模式向后端发出。 但是登录请求导致控制器日志指示控制器未找到/user url模式，因此UserDetailsS​​ervice返回null。 为了使客户端对后端/user url模式的请求能够找到控制器方法，从而正确地实例化自定义UserDetailsService需要对以下代码进行哪些特定更改？

该应用程序非常简单，控制器少于200行代码。

控制器的代码为： 

@SpringBootApplication
@Controller
@EnableJpaRepositories(basePackages = "demo", considerNestedRepositories = true)
public class UiApplication extends WebMvcConfigurerAdapter {

    // Match everything without a suffix (so not a static resource)
    @RequestMapping(value = "/{[path:[^\\.]*}")
    public String redirect() {
        // Forward to home page so that route is preserved.
        return "forward:/";
    }

    @RequestMapping("/user")
    @ResponseBody
    public Principal user(Principal user) {
        return user;
    }

    public static void main(String[] args) {
        SpringApplication.run(UiApplication.class, args);
    }

    @Bean
    public LocaleResolver localeResolver() {
        SessionLocaleResolver slr = new SessionLocaleResolver();
        slr.setDefaultLocale(Locale.US);
        return slr;
    }

    @Bean
    public LocaleChangeInterceptor localeChangeInterceptor() {
        LocaleChangeInterceptor lci = new LocaleChangeInterceptor();
        lci.setParamName("lang");
        return lci;
    }

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/login").setViewName("login");
    }

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(localeChangeInterceptor());
    }

找到控制器方法。 问题是此代码： 

if (user == null) {
    return null;
}

您可以在日志消息中清楚地看到： 

Authentication request for failed: org.springframework.security.authentication.InternalAuthenticationServiceException: UserDetailsService returned null, which is an interface contract violation

UserDetailsS​​ervice实现中不允许返回null。

因此，请检查数据库中是否有管理员用户的条目，然后删除return null并抛出UsernameNotFoundException 。
