那些遇到过的问题

Tomcat 7 + IntelliJ绝对的uri:http://java.sun.com/jsp/jstl/core问题

kam*_*mil 3 intellij-idea tomcat7

我从IntelliJ(Ultimate)IDE在tomcat 7上运行webapp时遇到了很大的问题.问题是,我无法taglib为我的jsp工作.我试图添加什么样的taglib并不重要,无论如何它都无法正常工作.JSP只有taglibs:

<%@ page contentType="text/html;charset=UTF-8" language="java" %> 
<%@ taglib prefix="dec" uri="http://www.opensymphony.com/sitemesh/decorator" %> 
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> 
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %> 
<%@ taglib uri="http://displaytag.sf.net" prefix="display" %>

和异常(对于每个taglib):

然而它无论如何都没有用.最有趣的是,当我将../webapps在Tomcat中生成的确切战争复制到目录中并手动运行时,它可以工作.任何线索为什么它不能从IDE工作？

Jav*_*aru 5

我用你的POM创建了一个hello world webapp,在我的hello.jsp页面上使用了JSTL taglib.工作良好.我可以通过删除POM中的jstl依赖项并进行干净的构建和部署来重现您的问题.因此,当您通过IDEA运行webapp时,似乎标签lib jars位于类路径中.因为它们在你的POM中有编译,所以它们应该是.或者更具体地说,它们应该在神器中.既然你提到你可以将战争复制到Tomcat并成功运行它,这让我相信,当通过IDEA运行你的webapp时,它不会使用该工件(即,战争文件)进行部署.在IDEA中创建tomcat运行/调试配置以使其部署爆炸战争而不是war文件本身并不罕见.这提供了能够即时更新资源的优点.

以下是您可以查看的一些内容:

进入tomcat运行/调试配置.在" 部署"选项卡上,查看正在部署的工件.它应该是maven-module-name:war或maven-module-name:war exploded.如果没有,请更改其中一个.如果是,请选择它并单击编辑图标.这将在" 项目结构"对话框中打开工件定义.如果它是war文件,它应该将归档定义显示为展开目录的战争.选择(在中间窗格中)maven-module-name:war exploded神器.展开WEB-INF/lib目录.确保标签lib jars显示在那里.如果没有,您可以尝试从maven工具窗口重新导入maven项目以使事情同步.您可能需要运行2到3次.(我有时会遇到需要的情况).一旦神器被纠正,你应该好好去.

如果神器很好,请尝试完全手动清理所有东西.IDEA认为罐子不存在时可能存在.当您启动tomcat时,在控制台输出中,您应该看到CATALINA_BASE设置为IDEA的config目录中的目录.在获得IDEA之后,请删除该目录.然后删除${CATALINA_HOME}/webapps目录(或至少删除您的应用程序目录和任何war文件).接下来删除IDEA正在构建的目标(或输出)目录.之后尝试通过IDEA启动tomcat实例.

如果webapp清理不起作用,请尝试使缓存File> Invalidate Caches失效,重新启动IDEA,并让它重新编制项目索引.您可能希望再次使用webapp完全清理这个.

如果这些都不起作用,我最好的建议是通过导入你的pom文件(File> Import Project并选择pom)来尝试创建新的IDEA项目.

哦,为了以防万一,请确保您使用的是最新版本的IDEA,12.1.6(或许可证的最新版本).有时它是简单的东西;)
