eclipse中创建springboot demo

1创建一个maven工程

2编辑pom.xml

<?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>  <groupId>com.springboot.test</groupId>  <artifactId>stringbootDemo</artifactId>  <version>0.0.1-SNAPSHOT</version>  <packaging>jar</packaging>  <name>stringbootDemo</name>  <url>http://maven.apache.org</url>  <properties>    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>  </properties>  <!-- Inherit defaults from Spring Boot -->      <parent>          <groupId>org.springframework.boot</groupId>          <artifactId>spring-boot-starter-parent</artifactId>          <version>1.4.0.BUILD-SNAPSHOT</version>      </parent>      <!-- Add typical dependencies for a web application -->      <dependencies>         <dependency>              <groupId>org.springframework.boot</groupId>              <artifactId>spring-boot-starter-web</artifactId>          </dependency>          <dependency>          <groupId>junit</groupId>          <artifactId>junit</artifactId>          <version>3.8.1</version>          <scope>test</scope>        </dependency>    </dependencies>      <!-- Package as an executable jar -->      <build>          <plugins>              <plugin>                  <groupId>org.springframework.boot</groupId>                  <artifactId>spring-boot-maven-plugin</artifactId>              </plugin>          </plugins>      </build>      <!-- Add Spring repositories -->      <!-- (you don't need this if you are using a .RELEASE version) -->      <repositories>          <repository>              <id>spring-snapshots</id>              <url>http://repo.spring.io/snapshot</url>              <snapshots><enabled>true</enabled></snapshots>          </repository>          <repository>              <id>spring-milestones</id>              <url>http://repo.spring.io/milestone</url>          </repository>      </repositories>      <pluginRepositories>          <pluginRepository>              <id>spring-snapshots</id>              <url>http://repo.spring.io/snapshot</url>          </pluginRepository>          <pluginRepository>              <id>spring-milestones</id>              <url>http://repo.spring.io/milestone</url>          </pluginRepository>      </pluginRepositories>  </project>

3 编制Application.java

package com.springboot.test.stringbootDemo;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;//@SpringBootApplication  //该方式在此配置中不好使,需使用下面三个组件@Configuration@ComponentScan@EnableAutoConfigurationpublic class Application {    public static void main(String[] args) {        // TODO Auto-generated method stub        SpringApplication.run(Application.class, args);    }}

4 编制Example.java

package com.springboot.test.stringbootDemo;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;@RestController@EnableAutoConfigurationpublic class Example {    @RequestMapping("/")    String home(){        return "hello world";    }    @RequestMapping("/haha/{myName}")    String index(@PathVariable String myName){        return "hello ... + " + myName+"!!!";    }}

5 选中项目 maven-update

6 选中项目 右键- run as -Java Application—控制台打印springboot启动日志
7 浏览器 输入 localhost:8080 出现
