SpringBoot 开发 IDEA intellij springboot2+intellij


1、系统要求:

  • Java 8 & 兼容java14 .
  • Maven 3.3+
  • idea 2019.1.2

2、Maven安装目录中找到conf文件夹的settings.xml文件,配置以下内容

<mirrors>
<mirror>
<id>nexus-aliyun</id>
<mirrorOf>central</mirrorOf>
<name>Nexus aliyun</name>
<url>http://maven.aliyun.com/nexus/content/groups/public</url>
</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>

3、参考SpringBoot2官方文档,实现需求:浏览发送/hello请求,响应 Hello,Spring Boot 2 

3.1新建一个Maven项目,在pom.xml中配置:

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.3.4.RELEASE</version>
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>

如下图:

3.2 右侧使用Maven下载依赖资源

 

3.3创建一个主程序类,项目入口

 

 

  3.4 接下来可以写MVC业务逻辑了,首先创建控制类,使用@RestController注解来说明,类中返回的数据是写向浏览器的(该注解包含了@controller和@ResponseBody)

 

3.5 启动SpringBoot:运行主程序代码

 

 

 

 

 如果启动发现控制台报错:端口陪占用,则重新配置端口:
