一个简单的spring boot应用程序具有自定义的UserDetailsService。 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UserDetailsService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？
该应用程序是如此简单，以至于控制器少于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

return user;
}

SpringApplication.run(UiApplication.class, args);

最佳答案
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
UserDetailsService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。关于java - 为什么UserDetailsService在Spring Boot应用程序中返回null？，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/34538768/
