1、利用mybatis写Dao层
@Select("<script> select count(*) from p_comment where 1=1 "
+"<if test='csid != null'> and csid = #{csid} </if>"
+"<if test='goal != null'> and goal < #{goal} </if>"
+ " limit #{startPosition}, #{maxResult}"
+ "</script>")
public Integer getCount(CommentsCondition cond);2、报错：
2018-09-05 15:59:35,986 [main] ERROR [org.mybatis.spring.mapper.MapperFactoryBean] - Error while adding the mapper 'interface com.eversec.protect.modules.article.dao.CommentsDao' to configuration.

2、查看了接口的所有的字段等，均没有问题；最后发现是因为"<" 得转义，按照mybatis的规则转义；
@Select("<script> select count(*) from p_comment where 1=1 "
+"<if test='csid != null'> and csid = #{csid} </if>"
+"<if test='goal != null'> and goal < #{goal} </if>"
+ " limit #{startPosition}, #{maxResult}"
+ "</script>")
public Integer getCount(CommentsCondition cond);3、正常执行，没有问题；
4、附：mybatis的转义字符：
<< 小于号；
>> 大于号；
& & 和 ；
' ‘’单引号；
" “” 双引号；
