首先,我将监听器保存在web.xml中
<listener>
<listener-class>
org.springframework.security.web.session.HttpSessionEventPublisher
</listener-class>
</listener>
然后我的springSecurity.xml就像
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:security="http://www.springframework.org/schema/security"
xmlns:context="http://www.springframework.org/schema/context"
xmlns="http://www.springframework.org/schema/beans"

</bean>
控制器如下:我需要登录的用户名列表。但是sessionRegistry没有工作。
@Autowired
@Qualifier("sessionRegistry")
private SessionRegistry sessionRegistry;
@RequestMapping(value = "/showUserStatus",method = RequestMethod.GET)
public ModelAndView showUserStatus() {
List<String> usersNamesList = new ArrayList<String>();
List<User> userList = new ArrayList<User>();
try {
List<Object> principals =sessionRegistry.getAllPrincipals();//the principals here is empty
for (Object principal: principals) {
//import org.springframework.security.core.userdetails for User class
//User is a built in class of spring security core
if (principal instanceof User) {
getLog().info(((User) principal).getUserName());
getLog().info("going to list userNameList");
usersNamesList.add(((User) principal).getUserName());
}
}
getLog().info("going to list user");
userList = getUserService().getList();
} catch (Exception er) {
getLog().error("error while listing userList" + er);
}
return new ModelAndView("/user/showUserStatus", "userList", userList);
}
任何人都可以帮助我,我做错了什么
答案 0 :(得分:0)
请尝试在xml文件中提及
<bean id="sessionRegistry"
class="org.springframework.security.core.session.SessionRegistryImpl" />
@Controller类
尝试注射如下
@Resource(name="sessionRegistry")
private SessionRegistryImpl sessionRegistry;
我想你差不多了。您唯一可能错过的是使用session-registry-alias
。通过在concurrency-control
元素上使用该属性,您可以公开会话注册表,以便将其注入您自己的bean。
现在您有一个会话注册表的引用,该注册表将由ConcurrentSessionControlStrategy
填充,该注册表由上述配置隐式设置。要使用它,您只需将其注入您的bean:
<security:session-management>
<security:concurrency-control max-sessions="10" session-registry-ref="sessionRegistry"/>
</security:session-management>
<bean id="sessionRegistry" class="org.springframework.security.core.session.SessionRegistryImpl"/>
或类似下面的内容
<bean id="sas" class="org.springframework.security.web.authentication.session.ConcurrentSessionControlStrategy"
p:maximumSessions="1" >
<constructor-arg name="sessionRegistry" ref="sessionRegistry" />
</bean>
