现在提起Java,几乎都会带上Spring;
大部分关于java的几乎都涉及到spring;
Spring项目中使用最多的就是SpringBoot;
所以后续的教程都以SpringBoot项目为例;
第一章:Java开发实战之SpringBoot项目搭建:
1、创建父工程:
打开Idea,选file>新建》项目
创建maven父工程,type需要选择pom
生成的pom.xml如下,可以直接使用;
<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.3.12.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<packaging>pom</packaging>
<groupId>com.exp</groupId>

<version>0.0.1-SNAPSHOT</version>
<name>demo</name>
<properties>

</project>
创建子工程:
在父工程点击右键》new>模块》点击下一步
其他操作参考父工程创建步骤;type不需要选择pom,默认既可
创建子工程另一种方式;在模块设置页选择maven
创建的子工程没有src目录,需要自己新建;
模块名》右键》新建目录》输入 src/main/java 》点击确定;
然后选择目录,标记为源码
子工程pom.xml文件。可以直接使用;
<?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">
<parent>
<artifactId>demo</artifactId>
<groupId>com.exp</groupId>
<version>0.0.1-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>demo-child</artifactId>
</project>
新建子工程后,需要在父工程pom文件中添加模块信息;
