Spring BootでのJSTLサポート

some limitations in the JSP supportがあることは知っていますが、Spring Boot WebアプリケーションでJSTLタグを使用してJSPを使用したいと考えています。Spring BootでのJSTLサポート

私のJSPファイルの抽出：だから

<%@ 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= ...

は、私がのpom.xmlには、以下の依存関係に追加：

<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>

ただし、JSPにアクセスする場合は、例外がスローされます：

解決策または回避策を知っている人はいますか？

環境：

春ブーツ1.5.6.RELEASE

私はThymeleafを使用して代替ソリューションを必要としません。

はEDIT：再現する

ステップ：

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

のpom.xmlには、以下の依存関係を追加します。

<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>

のsrc /メイン/リソース/ application.properties（起動時の例外を避けるために）に次のプロパティを追加します。
```
server.tomcat.additional-tld-skip-patterns=*.jar 
```

をメインのsrc /になtest.jspファイルを追加します/ Webアプリケーション：01に

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

mvn spring-boot:run

アクセス - >次の例外が発生します。

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

使用しているjstlのバージョンは？ –

私は1.2を使用しています。それはSpring Bootからのデフォルトを継承します。 ' org.springframework。boot spring-boot-starter-parent 1.5.6.RELEASE ' –

Ok。 pom.xml内の他の依存関係のいずれかの推移にもstandard.jarをもたらすかどうかをチェックするため、このjarファイルを除外した場合... –

この問題はserver.tomcat.additional-tld-skip-patterns=*.jarによって発生します。私はこの質問を終わらせます。

あなたは1.2バージョンでjstl依存関係を使用する必要があります。 pom.xmlにspring-boot-starter-parentを追加する必要があります。あなたは以下の依存関係を見つけることができます。

<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>

なぜspring-boot-starter-parentが必要ですか？ –

それはどういう意味ですか？ servlet-api 2.5を追加し、バージョン1.4.0.RELEASEにダウングレードする必要がありますか？ –
