IDEA 创建单模块之Spring Boot 项目

本文基于IntelliJ IDEA Community Edition 2022.1 版本演示。

第一步:创建Maven项目

 第二步:在pom.xml 文件中，添加SpringBoot 核心依赖jar包

<?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>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.2.RELEASE</version>
    </parent>

    <groupId>com.zzg</groupId>
    <artifactId>SmartMIS</artifactId>
    <version>1.0-SNAPSHOT</version>


    <properties>
        <java.version>1.8</java.version>
        <maven.compiler.source>8</maven.compiler.source>
        <maven.compiler.target>8</maven.compiler.target>
    </properties>

    <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>
            <exclusions>
                <exclusion>
                    <groupId>org.junit.vintage</groupId>
                    <artifactId>junit-vintage-engine</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>RELEASE</version>
            <scope>compile</scope>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>2.6.6</version>
            </plugin>
        </plugins>
    </build>


</project>

 第三步: 添加SpringBoot程序入口、简单测试Controller和application.properties

package com.zzg;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class MISApplicationStart {
    public static void main(String[] args) {
        SpringApplication.run(MISApplicationStart.class, args);
    }
}

package com.zzg.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class FirstController {
    @RequestMapping("/hello")
    public String get() {
        return "Hello MIS 医疗信息系统!";
    }
}

server.port=8081
server.servlet.context-path=/smartMIS

第四步：启动SpringBoot项目，并访问测试服务接口
