Java 如何配置Spring安全性以访问数据库中的用户详细信息？

我对SpringSecurity感到困惑。实现一件简单的事情有很多方法，我把它们都混在了一起

我的代码如下，但它抛出异常。如果我删除

UserDetailsService

相关代码，应用程序将运行，我可以在内存中登录

用户。如下所示，我将配置转换为基于XML的配置，但用户无法登录

我想您忘了在SecurityConfig类上添加此注释

@Configuration
@EnableWebMvcSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    @Qualifier("userDetailsService")
    UserDetailsService userDetailsService;

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

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/resources/**", "/", "/index", "/aboutus")
                .permitAll().antMatchers("/profile/**").hasRole("USER").and()
                .formLogin().loginPage("/signin").failureUrl("/signin?error")
                .permitAll().and().logout().logoutUrl("/signout").permitAll();

    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        PasswordEncoder encoder = new BCryptPasswordEncoder();
        return encoder;
    }

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

还有一件事我认为这个豆子是不需要的

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

请试试这个，希望对你有用

用于获取当前用户

public String getUsername() {
        SecurityContext context = SecurityContextHolder.getContext();
        Authentication authentication = context.getAuthentication();
        if (authentication == null)
            return null;
        Object principal = authentication.getPrincipal();
        if (principal instanceof UserDetails) {
            return ((UserDetails) principal).getUsername();
        } else {
            return principal.toString();
        }
    }


    public User getCurrentUser() {
        if (overridenCurrentUser != null) {
            return overridenCurrentUser;
        }
        User user = userRepository.findByUsername(getUsername());

        if (user == null)
            return user;
    }

谢谢

我认为问题可能是由于缺少

@ComponentScan

注释造成的。在

SecurityConfig

中尝试自动连接

userDetailsService

时，无法找到合适的bean进行自动连接

spring应用程序通常有一个单独的“应用程序上下文”，除了“mvc上下文”、“安全上下文”（您已经通过

SecurityConfig

获得了这些上下文）等

我不确定将

@ComponentScan

放在

SecurityConfig

本身上是否有效，但您可以尝试一下：

@Configuration
@ComponentScan("your_base_package_name_here")
@EnableWebMvcSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
...
}

将“your_base_package_name_here”替换为包含

@组件

或

@服务

类的包的名称

如果这不起作用，请添加一个新的空类，其中包含

@ComponentScan

注释：

@Configuration
@ComponentScan("your_base_package_name_here")
public class AppConfig {
    // Blank
}

来源：

Spring找不到带有限定符的bean

userDetailsService

。 我认为如果您忘记为Spring Security配置

UserDetailsService

的bean，您应该检查

applicationContext.xml

文件。如果有，请删除

@限定符（“UserDetailsService”）

再试一次

尝试更改字段类型：

@Configuration
@EnableWebMvcSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    @Qualifier("userDetailsService")
    MemberServiceImpl userDetailsService;

---

请参阅您的代码库中存在一些错误。请尝试通过查看下面的代码来解决此问题

删除SecurityConfig文件并转换为基于xml文件的配置

您的spring-security.xml应该如下所示

   <security:http auto-config="true" >  
  <security:intercept-url pattern="/index*" access="ROLE_USER" />  
  <security:form-login login-page="/login" default-target-url="/index"  
   authentication-failure-url="/fail2login" />  
  <security:logout logout-success-url="/logout" />  
 </security:http>  

    <security:authentication-manager>  
   <security:authentication-provider>  
     <!-- <security:user-service>  
   <security:user name="samplename" password="sweety" authorities="ROLE_USER" />  
     </security:user-service> -->  
     <security:jdbc-user-service data-source-ref="dataSource"    
      users-by-username-query="select username, password, active from users where username=?"   
          authorities-by-username-query="select us.username, ur.authority from users us, user_roles ur   
        where us.user_id = ur.user_id and us.username =?  "   
  />  
   </security:authentication-provider>  
 </security:authentication-manager>  

web.xml应该如下所示：

 <servlet>  
  <servlet-name>sdnext</servlet-name>  
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
        <load-on-startup>1</load-on-startup>  
 </servlet>

  <listener-class>  
                  org.springframework.web.context.ContextLoaderListener  
        </listener-class>  
 </listener>  

 <context-param>  
  <param-name>contextConfigLocation</param-name>  
  <param-value>  
   /WEB-INF/sdnext-*.xml,

您的“userDetailsService”bean声明为@Autowired，但它在SecurityConfig的上下文中不能作为类（MemberServiceImpl）使用

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = { "com.example" })
@Import(value = { LoginSecurityConfig.class })
public class LoginApplicationConfig 

我想在MVCWebApplication Initializer中应该包括MemberServiceImpl，也可以这样：

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

@覆盖
受保护类[]getRootConfigClasses（）{
返回新类[]{SecurityConfig.Class，MemberServiceImpl.Class}；
}

我在使用Wicket时遇到了相同的问题。 我可以通过改变AppInit类中的顺序来解决这个问题，首先扫描包，然后注册调用Bean

public class AppInit implements WebApplicationInitializer {
    @Override
    public void onStartup(ServletContext servletContext) throws ServletException 
{

        // Create webapp context
        AnnotationConfigWebApplicationContext root = new AnnotationConfigWebApplicationContext();
        root.scan("my_package");
        root.register(SpringSecurityConfiguration.class);
...#
}

尝试将以下方法添加到SecurityConfig：

@Bean
public UserDetailsService userDetailsServiceBean() throws Exception {
    return super.userDetailsServiceBean();
}

---

这里是答案，使用适当的@ComponentScan将解决，下面是我粘贴的示例代码片段，我也遇到了同样的问题并解决了。以下问题已解决，适用于与org.springframework.security.core.userdetails.userdetails服务的bean创建异常相关的问题

---

步骤1:编写安全应用程序配置类

import org.springframework.security.core.userdetails.UserDetailsService;

    @Configuration
    @EnableWebSecurity
    public class LoginSecurityConfig extends WebSecurityConfigurerAdapter {

        @Autowired
        @Qualifier("userDetailsServiceImpl")
        UserDetailsService userDetailsService;

此处@ComponentScan在LoginSecurityConfig中不是强制性的，您可以在根配置类中定义@ComponentScan，如下所示，并导入LoginSecurityConfig.classLoginSecurityConfig

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = { "com.example" })
@Import(value = { LoginSecurityConfig.class })
public class LoginApplicationConfig 

步骤2:现在自动连接SpringBeanorg.springframework.security.core.userdetails.userdetails服务

@Service（“userDetailsServiceImpl”）
公共类UserDetailsServiceImpl实现org.springframework.security.core.userdetails.UserDetailsService{
@自动连线
UserDao UserDao；
@凌驾
public UserDetails loadUserByUsername（字符串用户名）引发UsernameNotFoundException{
User=userDao.findByUsername（用户名）；
if（user==null）{
System.out.println（“未找到用户”）；
抛出新的UsernameNotFoundException（“找不到用户名”）；
}
返回新的org.springframework.security.core.userdetails.User（User.getUsername（），User.getPassword（），true，true，true，getGrantedAuthories（User））；
}
私有列表GetGrantedAuthories（用户）{
列表权限=新建ArrayList（）；
添加（新的SimpleGrantedAuthority（“角色用户”）；
返回当局；
}
}//下课

一方面，您说希望Spring security从DB检索用户，另一方面，您说，我引用“我需要使用Hibernate访问数据库中的用户。”。。到底是哪一个？您的代码似乎适合登录。“你到底想在这里干什么？”韦尔伯格的问题重新措辞。我正在使用spring security，我需要从db中读取用户详细信息。我的
