复制提示
1、new->maven->maven project, 勾选 Create a simple project， 下一个页面中填入group id（项目组织唯一标识, 如org.apache）和artifact id（应用名，本例子中为
SpringApplicationDemo），其他默认
2、配置pom.xml
<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.admin</groupId>
<artifactId>SpringTest</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging> <name>SpringApplicationDemo</name>
<description>Demo project for Spring Boot</description> <parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.3.RELEASE</version>
<relativePath /> <!-- lookup parent from repository -->
</parent> <dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency> <dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency> </dependencies> <build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
3、在src/main/java下新建包com.admin，新建类Application，作为程序入口
@SpringBootApplication
public class Application { public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
在包下新建类Controller类， 这里新建HelloController类
@RestController
public class HelloController { @RequestMapping("/hello")
public String test() {
return "Hello, World!";
}
}
4、在src/main/resources下新建application.properties文件，写上
server.port=8080
5、run as -> java application, 等待启动成功（查看console输出），
6、在浏览器中输入http://localhost:8080/hello
即可在浏览器中看到HelloController类中hello对应的字符串
