今天完成的事情：下载Eclipse J2EE版本，配置Maven，使用Eclipse构建Maven的SpringMVC项目

明天计划的事情：完成使用SpringMVC完成REST接口。

遇到的问题：

1.配置Maven报错

（http://www.th7.cn/Program/java/201407/245810.shtml 先装载slf4j-api包，重新启动eclipse后按http://stackoverflow.com/questions/8620127/maven-in-eclipse-step-by-step-installation再次安装Maven，安装成功）

2.配置web.xml报错

“The processing instruction target matching "[xX][mM][lL]" is not allowed.”

（http://bbs.csdn.net/topics/370090557，完全删除<?xml 前面的内容即可解决此问题！）

收获：学习使用Eclipse构建Maven的SpringMVC项目。

明早继续。睡了，晚安！
