異常：nested exception is java.sql.SQLException: Column count doesn‘t match value count at row 1

錯誤信息：org.springframework.jdbc.BadSqlGrammarException: StatementCallback; bad SQL grammar [insert into emp values(null,'張三',24,'男')]; nested exception is java.sql.SQLException: Column count doesn't match value count at row 1

原因：數據庫表的字段名數量和你插入數據的成員信息字段數量不匹配

解決辦法：字段有幾個就填幾個，可以爲null的用null填充，不能不寫
