1、配置spring boot的核心启动器;
2、添加starter模块;
首先maven的pom.xml文件内容如下:
<?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>org.example</groupId> <artifactId>spring_boot</artifactId> <version>1.0-SNAPSHOT</version> <properties> <maven.compiler.source>8</maven.compiler.source> <maven.compiler.target>8</maven.compiler.target> </properties> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.4.5</version> <relativePath/> <!-- lookup parent from repository --> </parent> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies> </project>
3、创建应用程序的App类(启动类);
package org.example; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class helloWorldApplication { public static void main(String[] args) { SpringApplication.run(helloWorldApplication.class, args); } }
4、创建一个controller模块,并运行:
package org.example.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.ResponseBody; @Controller public class HelloController { /* http://localhost:8080/hello */ @ResponseBody @RequestMapping("/hello") public String hello() { return "Hello World!____________china"; } //http://localhost:8080/123 @ResponseBody @RequestMapping("/123") public String home123() { return "中国您好"; } //http://localhost:8080/1234 @RequestMapping(value = "/1234",method = RequestMethod.GET) @ResponseBody public String home1234() { return "中国您好_123456"; } }
启动tomcat:
