JSTL support in Spring Boot

Question

Though I know that there are some limitations in the JSP support, I want to use JSP with JSTL tags in Spring Boot web application.

An extract of my JSP file:

<%@ page pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>

...

<c:catch var="ex">
    <c:if test="${!fn:contains(param.template,'../') && !fn:startsWith(param.template,'/')}">
        <c:import url=    ...

So, I added to the following dependencies to pom.xml:

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

<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-jasper</artifactId>
      <scope>provided</scope>
</dependency>

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
</dependency>

However, If accessing to the jsp, the exception is thrown:

2017-08-14 13:09:32.259 ERROR 2376 --- [nio-8080-exec-2] o.a.c.c.C.[.[localhost].[/].[jsp]        : Servlet.service() for servlet [jsp] in context with path [] threw exception [The absolute uri: [http://java.sun.com/jsp/jstl/core] cannot be

Does anyone know the solution or workaround?

Environment:

Spring Boot 1.5.6.RELEASE

I don't need alternative solutions using Thymeleaf.

EDIT:

Steps to reproduce:

git clone https://github.com/k-tamura/easybuggy4sb.git
cd easybuggy4sb

Add the following dependencies to pom.xml.

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

<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-jasper</artifactId>
      <scope>provided</scope>
</dependency>

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
</dependency>

Add the following property to src/main/resources/application.properties (in order to avoid exceptions during startup):
```
server.tomcat.additional-tld-skip-patterns=*.jar
```

Add test.jsp file into src/main/webapp:

<%@ page pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

mvn spring-boot:run

Access to http://localhost:8080/test.jsp -> The following exception occurs:

There was an unexpected error (type=Internal Server Error, status=500).
The absolute uri: [http://java.sun.com/jsp/jstl/core] cannot be resolved in either web.xml or the jar files deployed with this application

This problem is caused by server.tomcat.additional-tld-skip-patterns=*.jar. I will close this question.

you need to use jstl dependency with the 1.2 version. you also need to add spring-boot-starter-parent into your pom.xml. you can find dependency below.

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
</dependency>

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.4.0.RELEASE</version>
</parent>
