1.1SpringBoot

:maven

创建后

pom.xml

<projectxmlns="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>com.test.lz</groupId>

<artifactId>springboot2.0-firstProgram</artifactId>

<version>0.0.1-SNAPSHOT</version>

<parent>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-parent</artifactId>

<version>2.0.0.RELEASE</version>

</parent>

<dependencies>

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-web</artifactId>

<!-- 这个地方不用谢版本号，原因：在其parent中已经有定义了版本， -->

<build/>

</project>

jar

第三步：编写控制器类

package

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;

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

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

@RestController

@EnableAutoConfiguration

public class MemberController {

@RequestMapping("/memberIndex")

public String memberIndex(){

return "springboot 2.0 helloworld!";

}

public static void main(String[] args) {

SpringApplication.run(MemberController.class, args);

}

}

jre为1.5.

jre1.5 jre1.8

运行成功
