Spring環境搭建和示例工程
/**
* spring官網：https://spring.io/
下載地址http://projects.spring.io/spring-framework/
Spring Framework下的Reference
2.3. Usage scenarios
點選Distribution Zip Files
Distribution Zip Files
真實下載地址 http://repo.spring.io/release/org/springframework/spring
點選一個版本
然後點選最上層的第一個：spring-framework-4.3.3.RELEASE-dist.zip 解壓
* 第一步：新建一個普通java工程new-other-java Project
第二步：建立lib資料夾，引入spring-framework的jar檔案全部拷貝到工程中
javadoc和sources 結尾的不用拷貝
最主要的有：spring-aop、spring-beans、spring-context、spring-core
第三步：新增到buildPath:右鍵點選工程名稱-Properties-Java Build Path-Add JARs…
下載Apache Commons Logging
http://commons.apache.org/proper/commons-
commons-logging-1.2.jar也同上新增進去/
