配置JSTL 解决错误：org.apache.jasper.JasperException
在IDEA中SSM项目开发中，
在TomCat部署ssm项目时，JSTL的错误
错误如下：
1 org.apache.jasper.JasperException: 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 2 org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:55) 3 org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:277) 4 org.apache.jasper.compiler.ErrorDispatcher.jspError(ErrorDispatcher.java:75) 5 org.apache.jasper.compiler.TagLibraryInfoImpl.generateTldResourcePath(TagLibraryInfoImpl.java:250) 6 org.apache.jasper.compiler.TagLibraryInfoImpl.<init>(TagLibraryInfoImpl.java:125) 7 org.apache.jasper.compiler.Parser.parseTaglibDirective(Parser.java:421) 8 org.apache.jasper.compiler.Parser.parseDirective(Parser.java:479) 9 org.apache.jasper.compiler.Parser.parseElements(Parser.java:1435) 10 org.apache.jasper.compiler.Parser.parse(Parser.java:139) 11 org.apache.jasper.compiler.ParserController.doParse(ParserController.java:227) 12 org.apache.jasper.compiler.ParserController.parse(ParserController.java:100) 13 org.apache.jasper.compiler.Compiler.generateJava(Compiler.java:201) 14 org.apache.jasper.compiler.Compiler.compile(Compiler.java:358) 15 org.apache.jasper.compiler.Compiler.compile(Compiler.java:338) 16 org.apache.jasper.compiler.Compiler.compile(Compiler.java:325) 17 org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:580) 18 org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:363) 19 org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:396) 20 org.apache.jasper.servlet.JspServlet.service(JspServlet.java:340) 21 javax.servlet.http.HttpServlet.service(HttpServlet.java:729) 22 org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52) 23 org.springframework.web.servlet.view.InternalResourceView.renderMergedOutputModel(InternalResourceView.java:170) 24 org.springframework.web.servlet.view.AbstractView.render(AbstractView.java:314) 25 org.springframework.web.servlet.DispatcherServlet.render(DispatcherServlet.java:1325) 26 org.springframework.web.servlet.DispatcherServlet.processDispatchResult(DispatcherServlet.java:1069) 27 org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:1008) 28 org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:925) 29 org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:978) 30 org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:870) 31 javax.servlet.http.HttpServlet.service(HttpServlet.java:622) 32 org.springframework.web.servlet.FrameworkServlet.service(FrameworkServlet.java:855) 33 javax.servlet.http.HttpServlet.service(HttpServlet.java:729) 34 org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52) 35 org.springframework.web.filter.CharacterEncodingFilter.doFilterInternal(CharacterEncodingFilter.java:200) 36 org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:107)
解决办法：
在如下的库中找到箭头指向的几个文件
在External Libraries—>Maven:jstl:jstl:版本号—>jstl-1.2.jar—>META-INF中
也就是
c.tld
fmt.tld
fn.tld
sql.tld
x.tld
把这几个文档复制到如下箭头指向的路径中
然后重启Tomcat一般即可解决该问题！！！
