本文档主要作为本人的备忘录

    Spring boot的介绍基本上很容易搜到,这地方我就不多说了,直接介绍使用IDEA创建一个可运行的spring boot项目.

1.File -> New -> Project...

注意一点:将Default: https://start.spring.io 修改为: http://start.spring.io,否则有可能会连接不上

2.Next之后,填写自己的Group,Artifact等,选择Maven Project,Next,Next,Next,

3.最终生成此目录结构,FirstApplication.java 为spring boot的启动类.application.properties为配置文件

4.将 application.properties 修改为 application.yml, 添加配置项

server:  port: 8080 #Tomcat端口号  servlet-path: /first #context路径

注意:servlet-path路径前必须带 / 否则会

Caused by: java.lang.IllegalArgumentException: Error page location [first/error] must start with a '/'

5.修改pom.xml,因为这里要创建一个spring web项目,所以需要添加spring-web的依赖

                
     
      org.springframework.boot
                 
     
      spring-boot-starter-web
             
    

6.创建一个 FirstController

package com.aulbrother.first.web;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RestController;/** * @since 2018/1/22 9:50 */@RestControllerpublic class FirstController{    @GetMapping("/text")    public String text(){        return "success";    }}

7.启动项目

2018-01-22 10:40:42.300  INFO 8928 --- [           main] o.s.j.e.a.AnnotationMBeanExporter        : Registering beans for JMX exposure on startup2018-01-22 10:40:42.323  INFO 8928 --- [           main] s.b.c.e.t.TomcatEmbeddedServletContainer : Tomcat started on port(s): 8080 (http)2018-01-22 10:40:42.323  INFO 8928 --- [           main] com.aulbrother.first.FirstApplication    : Started FirstApplication in 1.761 seconds (JVM running for 2.559)

8.访问 http://localhost:8080/first/text,成功!!!!

最后贴上完整的pom.xml
