json

详细描述

--报错以下；

--然后在网上查到，原因是json-taglib 0.4.1 不能直接在POM中产生依赖，只有将其添加入本地仓库，并从pom.xml中加载，才能正确运行！

--我们需要在命令行mvn一下；

--mvn install:install-file -Dfile=D:\tool\json-taglib-0.4.1.jar   -DgroupId=atg.taglib.json  -DartifactId=json-taglib -Dversion=0.4.1  -Dpackaging=jar

--注意json-taglib的jar包位置；

--注意在本项目目录下运行；

--然后就是在pom文件中添加如下依赖；

<dependency>
   <groupId>atg.taglib.json</groupId>
   <artifactId>json-taglib</artifactId>
   <version>0.4.1</version>
</dependency>
--然后写jsp文件；

<%--使用@taglib指令添加json的标签库json-taglib--%>
<%@ page contentType="text/html;charset=UTF-8" language="java"

<c:forEach items="${stus}" var="s" varStatus="st">

--然后controller层如下；
