SpringBoot 就相当于不需要配置文件的Spring+SpringMVC。 常用的框架和第三方库都已经配置好了。
maven安装配置
管理项目依赖库的
maven的安装教程网上有很多，这里简单记录一下。
官网下载maven后并解压。
在其目录下添加一个目录repository
然后在conf目录下配置setting.xml文件，主要配置<localRepository></localRepository> <mirror></mirror>这两个标签
在<localRepository></localRepository>里指定刚刚repository的路径;
在<mirror></mirror>里配置获取依赖的镜像资源路径
<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd"> <localRepository>D:\installpath\apache-maven-3.6.1\repository</localRepository> <pluginGroups> </pluginGroups> <proxies> </proxies><servers></servers><mirrors><mirror> <id>nexus-aliyun</id> <name>nexus-aliyun</name> <url>http://maven.aliyun.com/nexus/content/groups/public</url> <mirrorOf>central</mirrorOf> </mirror> </mirrors><profiles><profile><id>jdk-1.8</id><activation><activeByDefault>true</activeByDefault><jdk>1.8</jdk> </activation> <properties> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion> </properties> </profile></profiles>
</settings>
可以在环境变量中配置一下maven的路径。
IDEA关联maven
方式一：使用spring boot 提供的初始化器
使用 spring boot 提供的初始化器。 向导的方式，完成 spring boot 项目的创建： 使用方便。
新建好后，在pom.xml中很多依赖
这是起步依赖
方式二：使用maven向导创建项目
然后手动添加配置文件等
然后再pom.xml中手动添加springboot依赖
<?xml version="1.0" encoding="UTF-8"?>
