javawebDay10-springboot项目搭建

• yml格式配置文件

spring:
  application:
    name: tilas-web-management

  #数据库连接信息
  datasource:
    url: jdbc:mysql://localhost:3306/tlias
    driver-class-name: com.mysql.cj.jdbc.Driver
    username: root
    password: 123456

特点：

1. 数值前面必须以空格作为分隔符
2. 以缩进作为层级的判断
3. "#"的一行作为注释

• restful格式的url
  以请求方式区分url的功能，而非通过请求路径区分
  

---

• result结果集

@Data
public class Result {
    private Integer code;//编码:1成功.0失败
    private String msg;//错误信息
    private Object data;//数据

    public static Result success(){
        Result result = new Result();
        result.code = 1;
        result.msg = "sucess";
        return result;
    }

    public static Result success(Object data){
        Result result = new Result();
        result.code = 1;
        result.msg = "sucess";
        result.data = data;
        return result;
    }

    public static Result error(String msg){
        Result result = new Result();
        result.code = 0;
        result.msg = msg;
        return result;
    }
}
