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

错误信息：org.springframework.jdbc.BadSqlGrammarException: StatementCallback; bad SQL grammar [insert into emp values(null,'张三',24,'男')]; nested exception is java.sql.SQLException: Column count doesn't match value count at row 1

原因：数据库表的字段名数量和你插入数据的成员信息字段数量不匹配

解决办法：字段有几个就填几个，可以为null的用null填充，不能不写
