一 新建Spring Boot项目
利用Maven新建Spring Boot项目后,生成的项目的根包目录下会有一个artifactId+Application命令规则的入口类。如下图所示:
二 添加测试控制器
为了演示简单,直接将控制器放在主类中。
package com.wisely.ch5_2_2;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@SpringBootApplication //主要目的是开启自动配置
public class Ch522Application {
@RequestMapping("/")
String index() {
return "Hello Spring Boot";
}
//作为项目启动入口
public static void main(String[] args) {
SpringApplication.run(Ch522Application.class, args);
}
}
三 编写pom.xml编写
<?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/4.0.0http://maven.apache.org/xsd/maven-4.0.0.xsd">

四 编写配置文件
#web访问端口
server.port=9090
五 编译和测试
1 编译
方式一:
方式二:
2 测试
访问http://localhost:9090
