idea 创建springboot项目之创建简单Controller

拼搏现实的明天。 2023-05-28 14:26 82阅读 0赞

使用idea创建springboot项目很简单，我再很早之前就会了，但是昨天 创建了一个 新建一个Controller之后居然不行，就很崩溃，故现在做个记录，为了以后方便查看

一。首先新建一个SpringBoot项目

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xpdXlpbmcxODAyMDI4OTE1_size_16_color_FFFFFF_t_70][]

二。填写Group和Artifact

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xpdXlpbmcxODAyMDI4OTE1_size_16_color_FFFFFF_t_70 1][]

三。这里选择Spring-Web

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xpdXlpbmcxODAyMDI4OTE1_size_16_color_FFFFFF_t_70 2][]

四。填写Project Name 和 路径

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xpdXlpbmcxODAyMDI4OTE1_size_16_color_FFFFFF_t_70 3][]

五。然后点击确定，选择合适的Maven 导入包

六。项目结构如下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xpdXlpbmcxODAyMDI4OTE1_size_16_color_FFFFFF_t_70 4][]

七。pom文件如下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xpdXlpbmcxODAyMDI4OTE1_size_16_color_FFFFFF_t_70 5][]

看，我们之前选择了spring-web，现在就有了Spring-Web的依赖

八。先启动一下项目

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xpdXlpbmcxODAyMDI4OTE1_size_16_color_FFFFFF_t_70 6][]

启动完毕

九。访问一下：

localhost:8080

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xpdXlpbmcxODAyMDI4OTE1_size_16_color_FFFFFF_t_70 7][]

说明项目正常启动

十。先建一个Controller

package com.taoj.demo.springbootdemo01.controller;
    
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    public class DemoController {
    
        @GetMapping("hello")
        public String sayHello(){
            return "hello Beijing";
        }
    
    }

十一。重启项目

十二。访问

[http://localhost:8080/hello][http_localhost_8080_hello]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xpdXlpbmcxODAyMDI4OTE1_size_16_color_FFFFFF_t_70 8][]

一切正常

不积跬步，无以至千里

不积小流，无以成江海
