前端發起請求以後返回以下資料
{
“code”: “-1”,
“msg”: “nested exception is org.apache.ibatis.exceptions.TooManyResultsException: Expected one result (or null) to be returned by selectOne(), but found: 6”,
“info”: null,
“error”: null
}
提示資訊顯示期待得到一個或者null的結果集,但是select語句返回了六個結果。很明顯是SQL語句的問題,可以檢視程式碼,找到對應的SQL語句,在navicat等工具下執行一次,看下結果個數
