Spring+SpringMVC+Mybatis框架搭建

项目建设完成之后的结构：


  

数据库的表结构如下：



环境建设：搭建Maven环境、Tomcat环境、需要MySql 数据库支持，使用的编程工具Eclipse （这些是前期准备）；

开始创建工程：

1.创建一个Maven工程：



选择webapp 



随便填写了：



创建完成之后工程会报错：

接下来怎么解决的？

选中项目点击右键，选择“Properties”  进入下面界面：

选中project facets ，然后将java版本改成 你的jdk版本，或者1.6以上版本。



之后选择 java build path



修改lib里面的java版本：

选中上面的jre System Library 然后选择 edit 

  

保存之后再看看工程。上面的操作主要是让目录结构显示正常。（上面的不一定可以解决问题，工程还是会报错的）

在pom.xml文件中添加依赖：

      <dependency>  

            <groupId>javax</groupId>  

            <artifactId>javaee-api</artifactId>  

            <version>7.0</version>  

        </dependency>  

这个立竿见影；不报错了。

之后再pom文件中添加依赖包，最终pom.xml文件如下：

到这里配置文件基本配置完毕

接下来怎么创建一个简单的实例运行：

可以参考这篇文章 http://blog.csdn.net/cool_easy/article/details/42778239   使用代码生成。生成

这三个包，还有几个文件需要自己创建。

代码结构如下
