[spring security] Principal in JSP EL expression

If you are using Maven, you need to add the taglibs library to your pom.xml.

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-taglibs</artifactId>
    <version>3.1.3.RELEASE</version>
</dependency>

 

Then in jsp added:

<%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags" %>

And:

<sec:authentication property="principal" />

 

Spring Security:

<%@page import="com.UserVO"%>
<%@page import="org.springframework.security.core.context.SecurityContextHolder"%>
<%@page import="org.springframework.security.core.Authentication"%>

<%
	Authentication auth = SecurityContextHolder.getContext().getAuthentication();
	UserVO userVo = (UserVO) auth.getPrincipal();
%>

var USER_CD = '<%=userVo.getUserCd() %>';
