maven WEB项目启动没问题访问页面就报错:org.apache.jasper.JasperException: Unable to compile class for JSP

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 file
The type java.io.ObjectInputStream cannot be resolved. It is indirectly referenced from required .class files

Stacktrace:
	org.apache.jasper.compiler.DefaultErrorHandler.javacError(DefaultErrorHandler.java:92)

	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
