今天在Eclipse配置Spring框架时发现不能在Eclipse的pom.xml->Dependencies->Add...加载spring-webmvc的框架
在此处输入spring-webmvc没有反应，只有本地的包能搜索到。
解决方案：
1.Windows->Preferences
.
在User Settings标题所示的目录下创建setting.xml，里面的内容为：
<?xml version="1.0"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

2.创建完毕后，去勾选
这一个条目
具体位置如下：
3.Apply and Close后，按alt+f5重构项目
把重构的项目勾上就行，然后就需要等待一下，时间后有些长，我大概花了5分钟左右，才完成。
