Spring boot taglibs

Question

I am using Spring boot.

I have a JSP page with the following tag libs:

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

When loading my jsp page, I get the following error:

The absolute uri: http://www.springframework.org/security/tags cannot be resolved in either web.xml or the jar files deployed with this application

These are my POM dependencies:

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>jstl</artifactId>
    </dependency>
    <dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-jasper</artifactId>
        <scope>provided</scope>
    </dependency>
</dependencies>

Any suggestions?

Answer 1

I added following dependency:

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

Now it works.

Answer 2

Add the following dependency

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

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>


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

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

Gradle users with Tomcat Plugin

If you are getting this error even if you have your dependency declared in gradle.build

runtime "org.springframework.security:spring-security-taglibs:${springSecurityVersion}"

And you are using the Tomcat plugin:

apply plugin: 'com.bmuschko.tomcat'

Then you MUST run the gradle tasktomcatRunWar instead of tomcatRun, so that the library is included in your servlet container.
