Spring Boot中的JSTL支持

时间：2017-08-14 04:41:23

标签： spring maven jsp spring-boot jstl

虽然我知道有some limitations in the JSP support，但我想在Spring Boot Web应用程序中使用带有JSTL标记的JSP。

我的JSP文件的摘录：

<%@ 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=    ...

所以，我向pom.xml添加了以下依赖项：

<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>

但是，如果访问jsp，则抛出异常：

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

有谁知道解决方案或解决方法？

环境：

  • Spring Boot 1.5.6.RELEASE

我不需要使用Thymeleaf的替代解决方案。

编辑：

重现的步骤：

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

  3. 将以下依赖项添加到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>

  4. 将以下属性添加到src / main / resources / application.properties（以避免启动时出现异常）：

    server.tomcat.additional-tld-skip-patterns=*.jar

  5. 将test.jsp文件添加到src / main / webapp：

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

  7. 访问http://localhost:8080/test.jsp - ＆GT;发生以下异常：

    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

2 个答案:

答案 0 :(得分：2)

此问题是由server.tomcat.additional-tld-skip-patterns=*.jar引起的。我将结束这个问题。

答案 1 :(得分：1)

您需要对jstl版本使用1.2依赖项。您还需要将spring-boot-starter-parent添加到pom.xml。你可以在下面找到依赖。

<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>
