Question

使用JDK 1.8和Spring Boot 1.2.0 RELEASE。

我的pom.xml文件：


curl -i -H 'Authorization: token xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' \
   -d '{ \
        "title": "sfsd", \
        "body": "We should have one", \
        "labels": ["中文"] \
      }' \

我的SecurityConfig文件：

package com.sampleapp;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }
}

我的示例应用程序中还有其他类和接口，但我希望尽可能保持这篇文章的简单和直接。

当我使用以下方式运行时：

mvn spring-boot：run

收到以下例外情况：

package com.sampleapp.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.security.SecurityProperties;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.annotation.Order;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

@Configuration                  
@EnableGlobalMethodSecurity(prePostEnabled = true)
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private UserDetailsService userDetailsService;

     @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
            .antMatchers("/", "/public/**").permitAll()
            .antMatchers("/users/**").hasAuthority("ADMIN")
            .anyRequest().fullyAuthenticated()
            .and()
            .formLogin()
            .loginPage("/login")
            .failureUrl("/login?error")
            .usernameParameter("email")
            .permitAll()
            .and()
            .logout()
            .logoutUrl("/logout")
            .deleteCookies("remember-me")
            .logoutSuccessUrl("/")
            .permitAll()
            .and()
            .rememberMe();
    }

    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService).passwordEncoder(new BCryptPasswordEncoder());
    }
}

我可能做错了什么？我查看了以下代码：

http://kielczewski.eu/2014/12/spring-boot-security-application/

我唯一改变的是sampleapp的应用程序名称以及一些包（名称空间）......

他的代码有效，但我想知道为什么我的代码没有？

已编辑（对于David Hernandez的提问）：

David，感谢评论，我不确定我是否理解你的问题，因为SecurityConfig文件使用了Spring的org.springframework.security.core.userdetails.UserDetailsService ...在我复制的代码中，有一个从Spring实现UserDetailService的CurrentUserDetailsService。如果这是你的问题，这里是代码：

快乐的节目！

Answer 1

您需要确保Application.java位于项目的根目录中如果你重构了包你应该有类似的东西

com
-sampleapp
--other packages
Application.java

默认情况下，spring boot使用@ComponentScan并在项目的根目录进行扫描

如果你的com.sampleapp之外有东西，@ ComponeScan将无法看到它

您可以将@ComponentScan添加到基础包

实施例

@ComponentScan( basePackages = {"package containing UserDetailsService", "packages containing your app"} )

在你的情况下，ComponentScan没有找到组件，所以我认为它是在错误的地方扫描

Answer 2

搞定了......我的服务类缺少@Service。
