spring boot單元測試之五:用mybatis+H2數據庫測試sql(spring boot 2.4.3)

一，關於H2數據庫:

   1,H2數據庫的用途:

      H2是一個用Java開發的嵌入式數據庫，可以直接嵌入到應用項目中。
  H2可以用於單元測試。它啟動速度很快，而且可以關閉持久化功能，使每一個用例執行完后就還原到初始狀態。

2,官方網站:

http://www.h2database.com/html/main.html

    private static final long serialVersionUID = 7498483649536881777L;
    //標識代碼，0表示成功，非0表示出錯
    private Integer code;
    //提示信息，通常供報錯時使用
    private String msg;
    //正常返回時返回的數據
    private Object data;

    public RestResult(Integer status, String msg, Object data) {
