查看版本對應的sts version
http://spring.io/tools3/sts/all
https://download.springsource.com/release/STS/3.9.7.RELEASE/dist/e4.10/spring-tool-suite-3.9.7.RELEASE-e4.10.0-win32-x86_64.zip
下載完成後是spring-tool-suite-3.7.3.RELEASE-e4.5.2-win32-x86_64.zip，類似這種文件，這是內置eclipse的STS IDE。不是我們需要的update
http://download.springsource.com/release/TOOLS/update/3.9.4.RELEASE/e4.8/springsource-tool-suite-3.9.4.RELEASE-e4.8.0-updatesite.zip
這個update版本，纔是我們需要的eclipse插件
Tip:
http://download.springsource.com/release/TOOLS/update/3.7.3.RELEASE/e4.5/springsource-tool-suite-3.7.3.RELEASE-e4.5.2-updatesite.zip
紅色爲sts插件的版本號， 藍色爲eclipse的版本號
