1.先maven install一次聚合工程taotao-manager，在本地maven仓库生成一把taotao-manager下面的4个子工程。
2.先启动taotao-manager-web，可能会报如下错，不过没关系。接着启动taotao-manager

3.常见报错
报错原因是下面这里没有找到TestMapper.xml
解决办法是在taotao-manager-dao下的个pom.xml里加上一个插件配置
配置插件后要重新maven install一次，只重新安装taotao-manager-dao子工程就可以了。
特别注意：如果上面的taotao-manager-dao下的src/main/resources/下有文件的话，加插件配置时，紧跟之前的插件配置，还需要加上如下配置(要拷贝哪些文件加在include里)，不过我们这里src/main/resources/下还没有文件，所以不用加：
另一种解决该报错的办法是，在src/main/resources下再建一个目录com/taotao/mapper/ ，然后把配置文件TestMapper.xml放进新新建的目录。这是因为当没有配置插件时，默认复制的是src/main/resources目录下的文件。
4.测试成功如下
