没有为委托PasswordEncoder中的id"null"映射的PasswordEncoder

Question

我是Spring安全的新手。使用Spring 4.3和Spring Security 5.0。一切都在运行。登录页面也出现了。如果您输入了错误的密码，则表明您的登录尝试未成功，请重试。好但正确的密码引发异常

我的Spring\u安全。XML是

 <authentication-manager>  
      <authentication-provider>  
        <user-service>  
        <user name="admin" password="1234" authorities="ROLE_USER" />  
        </user-service>  
      </authentication-provider>  
    </authentication-manager> 

我的网站。xml

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
        /WEB-INF/spring-security.xml,
         /WEB-INF/spring/appServlet/hibernate.xml
        </param-value>
    </context-param>



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




<filter>  
    <filter-name>springSecurityFilterChain</filter-name>  
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>  
</filter>  
<filter-mapping>  
    <filter-name>springSecurityFilterChain</filter-name>  
    <url-pattern>/*</url-pattern>  
</filter-mapping>  





<servlet>
    <servlet-name>appServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
     <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
        /WEB-INF/spring/appServlet/servlet-context.xml
        </param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>appServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

我的控制器类

 @RequestMapping(value="/admin", method=RequestMethod.GET)  
        public String privateHome() {  

            return "privatePage";  
        }  


When Run the Code /admin page its default run log in page .Everything Fine 

.一旦获得正确的凭据，就没有为id“null”映射的密码编码器

Answer 1

您可以查找以下问题的答案：Spring Security：将4.0迁移到5.0-错误-没有为id“null”映射的PasswordEncoder

然而，对于Spring Security 5，正确的定义是：

<bean id ="passwordEncoder" class = "org.springframework.security.crypto.password.NoOpPasswordEncoder" factory-method = "getInstance" />
