引入标签库时报错

jstl版本-1.2.jar
错误代码如下

org.apache.jasper.JasperException: /WEB-INF/views/list.jsp(3,60) Unable to read TLD "META-INF/c.tld" from JAR file "file:/D:/tool/eclipse-jee-photon/eclipse/WorkSpace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/ssm/WEB-INF/lib/jstl-1.2.jar": org.apache.jasper.JasperException: Failed to load or instantiate TagLibraryValidator class: org.apache.taglibs.standard.tlv.JstlCoreTLV

排查历史

  1. 进行jar包冲突排查,仍然报一样的错误
  2. 因为jstl1.2.jar本身自带standard.jar,应该是不会因为少这个包而报错的，但是保险起见，依然重新引入了standard.jar包，错误仍然存在
  3. 尝试了将c.tld文件从jstl1.2.jar包中解压出来放在WEB-INF文件夹下，并在web.xml中配置
<jsp-config>
		<taglib>
			<taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri>
			<taglib-location>/WEB-INF/c.tld</taglib-location>
		</taglib>
	</jsp-config>

依然报错

最后尝试通过降低jstl版本解决问题
在pom.xml文件中修改jstl配置为

<dependency>
			<groupId>jstl</groupId>
			<artifactId>jstl</artifactId>
			<version>1.1.2</version>
</dependency>

由于jstl1.1.2版本没有自带standard.jar,所以还需要添加standard配置，在pom.xml中添加配置

<dependency>
			<groupId>taglibs</groupId>
			<artifactId>standard</artifactId>
			<version>1.1.2</version>
</dependency>

重启服务后报错消失
