-Java and Spring Tutorials
-================
-
-This project is **a collection of small and focused tutorials** - each covering a single and well defined area of development in the Java ecosystem. 
-A strong focus of these is, of course, the Spring Framework - Spring, Spring Boot and Spring Security. 
-In additional to Spring, the modules here are covering a number of aspects in Java. 
-
-
-构建（build）项目
-====================
-如果你希望运行一个完整的构建（build），请运行命令：`mvn clean install`
-
-
-构建（Building）一个单独模块（module） 
-====================
-如果你希望构建一个特定的模块（module）的话，请在模块目录中运行命令：`mvn clean install`
-
-
-运行一个 Spring Boot 模块
-====================
-如果你希望运行一个 Spring Boot 模块（module）请在模块目录中（module directory）运行命令: `mvn spring-boot:run` 
-
-
-与 IDE 协同进行工作
-====================
-本仓库中包含有大量的模块。 
-When you're working with an individual module, there's no need to import all of them (or build all of them) - you can simply import that particular module in either Eclipse or IntelliJ. 
-
-
-运行测试
-=============
-运行 `mvn clean install` 将会在模块中运行单元测试（unit tests）。
-如果你希望运行整合测试（integration tests），请使用命令 `mvn clean install -Pintegration-lite-first`
