很是感谢,换了2.9的就好了,但是很奇怪又报jstl的问题了,我有配置依赖,网上查了相关解决办法都没用,麻烦您再帮我看看,详细描述在楼下。

感谢,之前是怀疑spring版本与jackson版本冲突问题,但是刚开始使用jackson2.5后来换成了7还是如此,看来是需要2.9,晚上尝试一下。

有时候也会是这个

我想知道这个跟web.xml的 头信息有没有关系?

页面上是这样子的

web.xml头信息是这样子的

pom.xml依赖我是这么配置的

    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>

检查页面的变量 使用el表达式的时候,有没有没有设置的变量值,还有语法错误,头<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
