mybatis 中test里面 应该为单引号套双引号

正确写法：test里面 应该为单引号套双引号

 

 

1.  
   <select id="findTopicPresetByCompanyIDAndCategory" parameterType="map" resultType="com.seeyon.esn.entity.portal.TopicPreset">
2.  
   select * from topicPreset where companyID = #{companyID}
3.  
   <if test='category=="0" '> and (category is null or category = "0")</if>
4.  
   <if test='category=="1" '> and category = "1"</if>
5.
