JSTL在Spring Boot中的支持

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JSP和JSTL标签。JSTL在Spring Boot中的支持

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，我加入到下面的依赖关系的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>

然而，如果访问到JSP，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：

春季启动1.5.6.RELEASE

我不需要使用Thymeleaf替代解决方案。

编辑：

重现步骤：

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

添加下面的依赖关系的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>

添加以下属性为src /主/资源/ application.properties（以避免启动时例外）：
```
server.tomcat.additional-tld-skip-patterns=*.jar 
```

添加test.jsp的文件到的src/main/Web应用程序：

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

mvn spring-boot:run

访问01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

您使用的是哪个版本的jstl？ –

我正在使用1.2。它继承Spring Boot的默认值。 ' org.springframework。boot spring-boot-starter-parent 1.5.6.RELEASE' –

好的。检查是否在pom.xml中的任何其他相关性带来standard.jar以及传递性，如果是排除这种罐子...... –

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

你需要使用jstl依赖与1.2版本。您还需要将spring-boot-starter-parent添加到您的pom.xml中。你可以在下面找到依赖关系。

<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>

为什么需要spring-boot-starter-parent？ –

这是什么意思？我应该添加servlet-api 2.5并降级到版本1.4.0.RELEASE吗？ –
