1.新建一個(gè)springboot初始化項(xiàng)目

2.輸入自己的包名，項(xiàng)目名及jdk版本，再點(diǎn)擊Next

3.勾選Spring Web，再點(diǎn)擊Next

4.再點(diǎn)擊Next，再Finish 默認(rèn)的項(xiàng)目結(jié)構(gòu)如下圖

（1）修改pom.xml文件

完整的pom.xml為：

<?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 https://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>2.4.5</version><relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.zou</groupId> <artifactId>springboot_demo</artifactId> <version>0.0.1-SNAPSHOT</version> <name>springboot_demo</name> <description>Demo project for Spring Boot</description> <properties><java.version>1.8</java.version> </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></dependency><dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.13.2</version></dependency><!--引入熱部署依賴--><dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId></dependency><!--引入lombok組件--><dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.16</version></dependency><dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-configuration-processor</artifactId> <optional>true</optional></dependency> </dependencies></project>

（2）新建一個(gè)ControllerDemo類

ControllerDemo的代碼如下

package com.zou.controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;/** * @author: 鄒祥發(fā) * @date: 2021/4/19 17:12 * springBoot啟動(dòng)程序的目錄一定要在controller等目錄的至少上一級(jí)，或者在SpringBootApplication 注解中添加屬性： * @SpringBootApplication(scanBasePackages = {'com.zou.controller'}) */@RestControllerpublic class ControllerDemo { @RequestMapping('/demo') public String demo(){return '小鄒太帥了'; }}

注：springBoot啟動(dòng)程序的目錄一定要在controller等目錄的至少上一級(jí)，或者在SpringBootApplication 注解中添加屬性：

@SpringBootApplication(scanBasePackages = {'com.zou.controller'})

（3）在application.properties中修改端口號(hào)

server.port=8081

（4）測(cè)試

（5）打開(kāi)瀏覽器，訪問(wèn)http://localhost:8081/demo，因?yàn)樵谥暗腃ontrollerDemo里面配置的訪問(wèn)路徑為/demo

（6）到這里第一個(gè)springboot開(kāi)發(fā)web的入門程序就完成了。

到此這篇關(guān)于使用springboot開(kāi)發(fā)的第一個(gè)web入門程序的實(shí)現(xiàn)的文章就介紹到這了,更多相關(guān)springboot web入門 內(nèi)容請(qǐng)搜索好吧啦網(wǎng)以前的文章或繼續(xù)瀏覽下面的相關(guān)文章希望大家以后多多支持好吧啦網(wǎng)！
