开发环境:win10专业版20H2+JDK8+Eclipse4.10.0
一、下载安装Maven
1.进入官网:https://maven.apache.org/download.cgi,下载maven最新版本apache-maven-3.8.1-bin.zip(目前是3.8.1)。
2.解压,配置本地资源库。我解压到的路径是:D:\eclipse-jee-2018-12-R-win32-x86_64\apache-maven-3.8.1,在此处新建名为repository的文件夹作为本地资源库。
3.配置系统环境变量:在Path下增加%JAVA_HOME%\bin,增加变量MAVEN_HOME,值为解压路径,我的是D:\eclipse-jee-2018-12-R-win32-x86_64\apache-maven-3.8.1。
二、配置Eclipse
1.打开Eclipse,选择Window->Preferences->Maven->User Settings。
2.修改相关参数,第一二个为Maven解压路径下\conf\settings.xml。第三个为本地资源库路径。
3.修改settings.xml,将JRE版本改为JDK8。在profiles下增加
<profile> <id>jdk-1.8</id> <activation> <activeByDefault>true</activeByDefault> <jdk>1.8</jdk> </activation> <properties> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion> </properties> </profile>
三、第一个Spring Boot应用
1.选择File->New->Other->Maven->Maven Project
2.依次选择,完成项目命名。
3.修改pom.xml配置文档
<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.fkit</groupId> <artifactId>hellotest</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>hellotest</name> <url>http://maven.apache.org</url> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.0.RELEASE</version> <relativePath/> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies> </project>
4.添加测试代码
修改App.java
package org.fkit.hellotest; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class App { public static void main(String[] args) { SpringApplication.run(App.class, args); } }
增加HelloController.java
package org.fkit.hellotest; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; //RestController @Controller + @ResponseBody @RestController public class HelloController { //"/hello" @RequestMapping("/hello") public String hello(){ return "Hello Spring Boot!"; } }
5.运行。打开浏览器,访问http://localhost:8080/hello
