springboot教程第一课_服务搭建及接口开发_接口挡板开发

目录

安装开发工具IDEA

新建springboot项目

添加restfull接口

启动项目验证

安装IDEA并下载JDK到本地，在IDEA上配置Project SDK的路径

新建项目选址Spring Initializr, Project SDK选择本地安装的版本；

新建项目时根据提示填好参数；

组件依赖可以选择必要的jpa和redis及辅助插件lombok；

把配置文件改为yml文件

server:
  port: 9999
spring:
  profiles:
    active: dev

添加dev环境的配置文件

server:
  servlet:
    context-path: /demo

去掉数据库的校验（暂时不需要使用数据库）

package org.demo.springboot;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
 
import javax.sql.DataSource;
 
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
public class SpringbootApplication {
 
    public static void main(String[] args) {
        SpringApplication.run(SpringbootApplication.class, args);
    }
 
}

添加restfull接口：

package org.demo.springboot.order;
 
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
 
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;

 */
@RestController
@RequestMapping("/order")
public class OrderController {
 
    @GetMapping("/queryAll")
    public List<HashMap<String,String>> queryAll(){
        List<HashMap<String, String>> res = new ArrayList<>();
        HashMap<String, String> r = new HashMap<>();
        r.put("1","hello");
        res.add(r);
 
        return res;
    }
}

启动项目后在浏览器中验证接口
