ssm+maven+eclipse框架搭建

ssm框架搭建

因为之前没有独立搭建过ssm框架，做的项目也都是从视频上看着照做，没有自己的想法，也不符合自己的意愿，同时对ssm整合的了解并没有起到太大的作用，所以自己尝试搭建了一个ssm的框架，现在记录一下个个配置，以便以后搭建框架出先问题可以回来查阅。

一：首先创建maven工程（因为以前在学校搭建ssh框架自己找jar包，各种依赖不对应，各种jar包找不到，所以现在很喜欢maven这个依赖管理工具）。

这中间需要注意的是下面这个图要选择webapp这个选项（之前看教程说是这个webapp的版本也有讲究，但是我这次配置没有改也成功了，所以就先不管了，以后遇到这个问题在说吧）

 

二：名字什么的都起好之后，点击finish，现在的项目结构是这样的

 

跟咱们平时的web项目相比少了一些东西（而且我这里的maven是修改过conf下的setting文件的，否者他的JRE默认是1.5的，不过我们都是需要修改的）。然后我们右键项目进入BulidPath中

 

这里很明显少了server（因为我是在修改了maven的jar包地址的同时写这篇博客，本来项目没有server环境的话index.jsp是应该报错的），我们点击上图中的add Library

 

把我画红线的两个都配置成本地的（记住是你本地的，不是myeclipse中的，因为myeclipse之类的IDE都会模仿你本地的tomcat所以在配置的时候要格外注意。具体要怎么正确使用本地的tomcat而不是被myeclipse克隆的tomcat欺骗了，我在以后的博客中会写）

三：上面两步完成后maven项目就算时建成了，下面开始整合ssm。这里只记录各个配置文件的写法，并不写这样整合的原理（因为在下不会，不懂，日后会了再说）

先上一下项目结构，这是我认为比较舒服的项目结构

 

其中的各个文件就不介绍作用了，自己都懂，不懂看下名字也都知道是什么意思

粘一下各个配置文件的内容

然后就可以开始写代码了，这中间有很多坑，也有很多要注意的地方，但是今天下班了，明天再补充吧

要注意有个webapp的版本要修改成3.0，它自动生成的web.xml文件的头也要修改，网上查一下ssm框架搭建，基本都有教程
