如何将值添加到Spring SecurityContextHolder中

Question

我有登录参数

1.userName

2.password

3.companyId

我使用以下代码获得了用户名和密码

 Authentication auth = SecurityContextHolder.getContext().getAuthentication();

 String name = auth.getName();

 String pwd = auth.getCredentials();

 String companyId= ???//How can i set and then get company Id here.

我的问题是如何使用SecurityContextHolder获得额外的登录参数(companyId)？

提取类可能不是spring控制器.这就是我使用SecurityContextHolder而不是HttpSession的原因.

谢谢,

创建简单的SpringSecurityFilter过滤器.使用setDetails方法为用户添加额外的详细信息.

package org.example;  
public class CustomDeatilsSecurityFilter extends SpringSecurityFilter {

   protected void doFilterHttp(HttpServletRequest request, HttpServletResponse response, FilterChain chain) {
      SecurityContext sec = SecurityContextHolder.getContent();
      AbstractAuthenticationToken auth = (AbstractAuthenticationToken)sec.getAuthentication();
      HashMap<String, Object> info = new HashMap<String, Object>();
      info.put("companyId", 42);
      auth.setDetails(info);
   }

}

像这样将它添加到Spring Security Filter Chain(这不是web.xml,但类似于applicationContext-security.xml):

<bean id="customDeatilsSecurityFilter" class="org.example.CustomDeatilsSecurityFilter">
   <custom-filter position="LAST" />
</bean>

然后在代码中的某处你可以做这样的事情:

Map<String, Object> info = (Map<String, Object>)SecurityContextHolder.getContext().getAuthentication.getDetails();  
int companyId = info.get("companyId");  

在web.xml中基本安装Spring Security

<context-param>
    <param-name>patchConfigLocation</param-name>
    <param-value>
        classpath:/applicationContext.xml
       /WEB-INF/applicationContext-datasource.xml
       /WEB-INF/applicationContext-security.xml
    </param-value>
</context-param>

<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>

在applicationContext-security.xml中

<?xml version="1.0" encoding="UTF-8"?>

    </bean>
