用ssm框架做毕设——————————————上面是我的报错

这个报错困扰了我整整一天半，难受啊马飞~

下面是我的mapper.xml:

    
        
	       
               lkm_name like "%"#{lkm_name}"%"
	       
	       
	        and lkm_gender = #{lkm_gender}
	       
            /*所属客户*/
	       
	        and lkm_cust_id = #{lkm_cust_id}
	       
        
    
	
	
		SELECT
			lkm_id,
            lkm_name,
            lkm_cust_id,
			lkm_gender,
            lkm_phone,
            lkm_mobile,
            lkm_email,
            lkm_qq,
            lkm_position,
            lkm_memo
		FROM
			linkman l
	    /*多条件查询*/
		
        
        

            LIMIT #{start_index},#{rows}
        
	

我知道你肯定不耐烦了，哈哈~~~

这个错误，大部分人肯定是字段用了mysql的关键字导致的。

你可以先把sql语句去数据库执行一下，重点看字段和表名啊，千万别用mysql关键字。

还有就是limit的参数也别用mysql关键字

而我的问题就有丶秀了，因为爱写注释的好习惯，但我把注释写到了标签里面去了，还是/*   */这种形式（用的ctrl+shift+/快捷键）

这会导致什么结果呢：无论你中的条件是否成立，mybatis都会给你拼接一个where

只要去掉注释就OK了，或者改用注释。
