Spring Boot中的JSTL支持

2019-11-11 05:22:35  阅读：243  来源： 互联网

标签：spring-boot maven jstl spring jsp


虽然我知道有some limitations in the JSP support,但是我想在Spring Boot Web应用程序中将JSP与JSTL标记一起使用.

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=    ...

因此,我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>

但是,如果访问jsp,则会引发异常：

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

有人知道解决方案或解决方法吗？

环境：

> Spring Boot 1.5.6.发布

我不需要使用Thymeleaf的替代解决方案.

编辑：

重现步骤：

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

>将以下属性添加到src / main / resources / application.properties中(为了避免启动期间出现异常)：

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

>将test.jsp文件添加到src / main / webapp中：

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

> mvn spring-boot：运行
>访问http://localhost:8080/test.jsp
->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

解决方法:

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