intelij idea创建spring boot聚合工程

本文主要是介绍intelij idea创建spring boot聚合工程，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1、快速创建spring boot工程（父工程）。

（1.1） File -> New - > Project -> Spring Assistant-> 点击Next 。如图选择default,然后点击next。

（1.2）填写项目相关信息，如图：

（1.3）下一步，选择core下devtools（热部署），如图：

（1.4）选择文件位置：

（1.5）创建完之后删除src目录，并修改pom.xml，如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.tianshuhao</groupId><artifactId>tianshuhao-parent</artifactId><version>0.0.1-SNAPSHOT</version><packaging>pom</packaging><name>tianshuhao-parent</name><description>tianshuhao-parent project for Spring Boot</description><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.0.6.RELEASE</version><relativePath/> <!-- lookup parent from repository --></parent><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding><java.version>1.8</java.version><fastjson.version>1.2.51</fastjson.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-dependencies</artifactId><version>2.0.6.RELEASE</version><type>pom</type><scope>import</scope></dependency><!--热部署--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-devtools</artifactId><scope>runtime</scope></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies><build><!-- 产生构件的文件名，默认${artifactId}-${version} --><finalName>tianshuhao-parent</finalName><pluginManagement><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></pluginManagement><plugins><!-- 跳过测试 --><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-surefire-plugin</artifactId><configuration><skip>true</skip></configuration></plugin></plugins></build>
</project>

2、创建核心模块core，entity，dao，service，web。

（2.1）项目上右键单击new-----Module：

（2.2）选择core下的lombok(简化代码，可省略getter/setter/toString等方法)，选择路径，如图：

（2.3）模仿core创建其他模块，entity，dao，service和web（其中web打包方式选择war，最后一步项目依赖添加web），如图：

（2.4）创建完后目录结构如图：

（2.5）删除各个模块包下的无用类，只保留到包即可（web模块除外）。

3、父工程的pom.xml文件添加<modules>标签，如图：

4、子模块添加父工程，entity，dao，service，web模块依赖core模块，dao添加entity模块......最后：

（4.1）core模块的pom.xml:

</project>

5、项目打包，调出maven projects窗口，如图目录运行run maven build：

6、控制台显示build success表示打包成功，如图：

7、修改web模块的application.proterties为application.yml，并添加一下内容：

8、同级目录（resources）下添加文件application-dev.properties，内容为空即可。

9、web子模块的Application启动类:

10、运行main方法，访问地址：http://localhost:8080/tianshuhao-web/test
