eclipse如何创建spring boot工程：
第一步：首先打开eclipse，找到图中的下图的中“下三角”符号，选中"working sets"(表示将会把eclipse中的工程以working sets方式呈现，而不是单个project列表呈现)
第二步：依然是找出上图的菜单，点击“Select Working Set...”，弹出框：
点击“New...”可以新建新的working set，也可以配置当前工作区域显示哪些，不显示哪些working set。
第三步：通过上边的配置，我们新增一个springboot的working set，选中springboot该working set，然后新建maven工程：
SpringBoot工程创建操作步骤描述：
1）先选中springboot该working set；
2）在eclipse的导航栏中选中file->new->maven project；
3）在“New Maven Project”窗口中，勾选“Create a simple project(skip archetype selection)”
4）新建好的maven工程如下：
备注：
如果此时maven的pom.xml第一行出现错误：org.apache.maven.archiver.MavenArchiver.getManifest(org.apache.maven.project.MavenProject, org.apache.maven.archiver.MavenArchiveConfiguration)
解决方案：
a、Help——>Install New SoftWare
b、http://repo1.maven.org/maven2/.m2e/connectors/m2eclipse-mavenarchiver/0.17.2/N/LATEST/
c、按照安装提示，一直next，重启eclipse之后，执行maven-update project。
5）在pom.xml中添加spring boot 2.0.1的依赖信息：
1 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 2 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 3 <modelVersion>4.0.0</modelVersion> 4 <groupId>com.dx</groupId> 5 <artifactId>springboot-helloword</artifactId> 6 <version>0.0.1-SNAPSHOT</version> 7 <!-- springboot父类依赖 --> 8 <parent> 9 <groupId>org.springframework.boot</groupId> 10 <artifactId>spring-boot-starter-parent</artifactId> 11 <version>2.0.1.RELEASE</version> 12 </parent> 13 14 <dependencies> 15 <!-- springboot web组件依赖 --> 16 <dependency> 17 <groupId>org.springframework.boot</groupId> 18 <artifactId>spring-boot-starter-web</artifactId> 19 </dependency> 20 </dependencies> 21 </project>
6）在src下新建com.dx.controller包，在包下创建HelloWordController.java
package com.dx.controller; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; @EnableAutoConfiguration @Controller public class HelloWordController { @RequestMapping(value = "/index", method = RequestMethod.GET) public String index() { System.out.println("index is running..."); return "welcome"; } }
7）在com.dx.controller包下，创建MyApplication.java
import com.dx.controller.HelloWordController; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class MyApplication { public static void main(String[] args) { SpringApplication.run(HelloWordController.class, args); } }
此时，工程文件结构如下：
8）运行测试，在MyApplication.java编辑窗口中右键，run as -> Spring Boot App
运行后，访问：http://localhost:8080/index
运行窗口打印信息如下：

idea创建springboot工程：
1）新建一个空的工程：
2）新建空工程完成后，打开“Project Structure...”面板，新建maven工程
新建一个Module，把该Module作为一个maven工程来创建：
选中maven工程，来创建一个maven工程：
一步一步完成，把工程名字定义为springboot_helloword：
3）修改maven工程的pom.xml配置为如下：
<?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.dx</groupId> <artifactId>springboot-helloword</artifactId> <version>1.0-SNAPSHOT</version> <description>Demo project for Spring Boot</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.1.RELEASE</version> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <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>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
4）新建完成的maven工程添加类，资源文件
a）新建com.dx.controller.HelloWordController.java、MyApplication.java
1 package com.dx.controller; 2 3 import org.springframework.boot.autoconfigure.EnableAutoConfiguration; 4 import org.springframework.stereotype.Controller; 5 import org.springframework.web.bind.annotation.RequestMapping; 6 import org.springframework.web.bind.annotation.RequestMethod; 7 8 @EnableAutoConfiguration 9 @Controller 10 public class HelloWordController { 11 @RequestMapping(value = "/index", method = RequestMethod.GET) 12 public String index() { 13 System.out.println("index is running..."); 14 return "welcome"; 15 } 16 }
1 import com.dx.controller.HelloWordController; 2 import org.springframework.boot.SpringApplication; 3 import org.springframework.boot.autoconfigure.SpringBootApplication; 4 5 @SpringBootApplication 6 public class MyApplication { 7 public static void main(String[] args) { 8 SpringApplication.run(HelloWordController.class, args); 9 } 10 }
b）在资源文件夹下添加配置文件application.properties
#修改tomcat的默认的端口号，将8080改为8888
server.port=8888
c）添加css配置test.css：
body { padding: 0px; margin: auto; font-family: "黑体", "仿宋", Arial, "Arial Unicode MS", System; background-color: #00F; font-size: 20px; text-align: left; }
d）添加html静态模版文件welcome.html：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <link href="css/test.css" rel="stylesheet"/> <body> <p>welcome page is login.........</p> </body> </html>
5）运行测试：
浏览器中输入：http://127.0.0.1:8888/index
