一个spring3.2的项目 从jdk1.7放到1.8的环境中编译，打开网页异常：spring jar包版本升级经历

背景：一个历史项目用的是 spring3.2 的版本，在jdk1.7中运行没有问题，但是如果在jdk1.8中运行就会报错

 之前百度折腾过，说是spring 版本和jdk 冲突。要么就把spring 版本升级到4.0以上。本人下面的博客的第二点有说明：

 　　http://www.cnblogs.com/rogge7/p/7241456.html

决定：心想总是要解决的，准备把spring相关的包升级到4以上的版本，那问题了，找jar包是个问题，找多少版本是个问题，相关连的包？？

步骤：1、原来项目的jar包

　　

如果去网上找？本地项目或仓库找？ 一个个找感觉都不现实。想到一个方法，新建一个Maven项目，全部的导入相关的依赖包，把这些包导出来，替换到旧项目。

2、新建Maven项目， 添加添加相关jar（不懂百度）

Maven配置 和创建一个Maven项目 - 海蓝steven - 博客园 -- 5、添加jar包
http://www.cnblogs.com/rogge7/p/7272594.html

　　

　　

 3、导出jar包

maven导出项目依赖的jar包 - java学习开发 - CSDN博客
http://blog.csdn.net/fendou123_love/article/details/46356823

   导出到自定义目录中

    在maven项目下创建lib文件夹（不创建也可以，自定义其它的文件夹名也可以），输入以下命令：

         mvn dependency:copy-dependencies -DoutputDirectory=lib

    maven项目所依赖的jar包都会复制到项目目录下的lib目录下

   

 等待运行完成后，Maven项目下就会多了lib的文件夹

　　

4、把旧项目的jar包换成新的就可以打开网页了。大功告成

 

拓展：Maven仓库估计没有配置远程的服务器，搜索的时候未能显示到jar包的其它版本（都是本地的）。待学习

 ==2017-11-13 18:18   把已经改造好的项目 从jdk1.8放到jdk1.7的环境运行：
