|
||||
Here's the new "Learn Spring" course: <br/>
|
||||

||||
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`
