[JAVA] Use Spring Security JSP tags with FreeMarker

Thing you want to do

I want to use JSP tags such as <security: authorize> on FreeMarker. I would like to confirm for myself that it was introduced at https://vorba.ch/2018/spring-boot-freemarker-security-jsp-taglib.html.

It seems that FreeMarker originally has a function to use JSP tags. → Reference URL





The point is that you need the Spring Security JSP tag (spring-security-taglibs) and JSP API (tomcat-jsp-api).

Java Config class


public class MyFreeMarkerConfig {

    private final FreeMarkerConfigurer freeMarkerConfigurer;

    public MyFreeMarkerConfig(FreeMarkerConfigurer freeMarkerConfigurer) {
        this.freeMarkerConfigurer = freeMarkerConfigurer;

    public void init() {

The point is to specify the path of the TLD file.

How to write the screen


<#assign security=JspTaglibs["http://www.springframework.org/security/tags"]/>
    <meta charset="UTF-8">
<@security.authorize access="isAuthenticated()">
    <p>Hello, <@security.authentication property="principal.username"/>!</p>
<p><a href="/secret">Go to secret page</a></p>
<form action="/logout" method="post">
    <input type="submit" value="Logout">
    <input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}" />

Specify the JSP tags with <# assign security = JspTaglibs [" http://www.springframework.org/security/tags "] />.

When using tags, <@ security. Tag name Property name =" Property value ">.
