一、问题描述

eclipse通过maven插件创建一个WEB项目通过内嵌Tomcat加载项目，启动没问题，一访问页面就报错提示无法将jsp编译为class文件:

org.apache.jasper.JasperException: Unable to compile class for JSP: An error occurred at line: 1 in the generated java fileThe type java.io.ObjectInputStream cannot be resolved. It is indirectly referenced from required .class filesStacktrace:org.apache.jasper.compiler.DefaultErrorHandler.javacError(DefaultErrorHandler.java:92)org.apache.jasper.compiler.ErrorDispatcher.javacError(ErrorDispatcher.java:330)org.apache.jasper.compiler.JDTCompiler.generateClass(JDTCompiler.java:439)org.apache.jasper.compiler.Compiler.compile(Compiler.java:349)org.apache.jasper.compiler.Compiler.compile(Compiler.java:327)org.apache.jasper.compiler.Compiler.compile(Compiler.java:314)org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:592)org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:317)org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:313)org.apache.jasper.servlet.JspServlet.service(JspServlet.java:260)javax.servlet.http.HttpServlet.service(HttpServlet.java:717)

错误的原因为：tomcat6不支持jdk1.8版本

 <build>    <plugins>      <plugin>      <groupId>org.apache.tomcat.maven</groupId>      <artifactId>tomcat7-maven-plugin</artifactId>      <version>2.2</version>      <configuration>      <url>http://localhost:8080/manager/text</url>       <path>/</path>      <server>tomcat</server>      <username>tomcat</username>      <password>123456</password>      </configuration>      </plugin>    </plugins>  </build>

二、解决方法

找了下发现原来是这里出了问题!!!

把它改为: tomcat7:run 就行了
