自己搭建一个SSM框架
工作中我们或多或少都需要自己搭建一个框架，现在常见的Java开源框架组合方式主要为：SSH，spring+springMVC+Mybatis，SSM。
其中SSM目前无论是培训机构培训亦或是招聘。都会将会使用SSM框架作为一个重要能力来作为培训或是招聘的重要目标之一，下面我将自己自学时搭建的一个SSM项目分享出来，供初学者参阅。
1.第一步，我们需要搭建好自己的开发环境（IDE） 笔者使用的是myeclipse+tomcat+mysql
2.第二步创建一个web工程 工程名自定义，创建好了之后按照MVC设计模式创建好所有的包或文件夹（domain用于存放javabean对象，config用于存放所有的配置文件），并将SSM框架所需要的所有jar包导入到项目中
3.编写项目的配置文件(配置文件中每部分的含义，有详细的注释说明)
a.spring的配置文件application-context.xml配置文件

配置到这一步之后，会发现，现在需要手动创建javabean实例、dao层的接口以及javabean对应表格的mapper配置文件，因此，这里用到了一个mybatis逆向工程的插件，用于自动生成上述三个部分
4.配置mybatis的逆向工程插件
a.首先需要在myeclipse的安装目录中添加逆向工程
首先找见安装目录中的MyEclipse 10下创建add-plugins\mybatis-generater文件夹，然后将逆向工程压缩包解压之后的两个文件夹放到改目录下
D:\myprogram1\myeclipse10\MyEclipse 10\add-plugins\mybatis-generater
其次在myeclipse的安装目录D:\myprogram1\myeclipse10\MyEclipse 10\dropins下创建mybatis.link文件（后缀为.link），文件内容为：path=D:\\myprogram1\\myeclipse10\\MyEclipse 10\\add-plugins\\mybatis-generater
重启myecplise,将中generatorConfig.xml添加到项目中
