SpringSource Tool Suite 基于 Spring IDE ，提供了其它的一些特性，如 基于Spring dm Server 的osgi 开发，及其它一些 Spring 项目的支持，如Spring Roo， Spring Batch等。
在浏览器输入 https://spring.io/tools 进入网页，根据你的操作系统，选择合适版本。如下图：
笔者电脑为 Win10，因此笔者选择了“WINDOWS 64-BIT”版本，下载地址：https://download.springsource.com/release/STS4/4.7.0.RELEASE/dist/e4.16/spring-tool-suite-4-4.7.0.RELEASE-e4.16.0-win32.win32.x86_64.self-extracting.jar
下载成功你的磁盘将多出“spring-tool-suite-4-4.7.0.RELEASE-e4.16.0-win32.win32.x86_64.self-extracting.jar”文件。我们可以打开 DOS 窗口，输入“java -jar spring-tool-suite-4-4.7.0.RELEASE-e4.16.0-win32.win32.x86_64.self-extracting.jar”对文件进行解压，步骤如下：
下载过程中将会出现一个进度条，如下图：
解压完成后，会出现如下目录。如下图：
双击“SpringToolSuite4.exe”启动软件。如下图：
（1）选择“File”、“New”、“Spring Starter Project”菜单，去打开创建 Spring Boot 项目的弹出框。如下图：
（2）根据自己的实际情况填写项目名称、项目类型（Maven、Gradle）、打包类型、编程语言、Java版本、Maven Group、Maven Artifact等信息。如下：
填写完项目信息后，点击“Next”按钮。
（3）为项目添加依赖，左边为可选依赖，右边为已选择的依赖。如下图：
项目依赖选择完后后，点击“Finish”完成项目创建。
（4）项目创建完成后，项目结构如下图：
（5）运行“Demo1Application”类，运行结果如下图：
