Mybatis 实现一个搜索框对多个字段进行模糊查询

 <if test="featureCode != null">
 AND plm_model_option.feature_code= #{featureCode}
 </if>
 <if test="featureName != null">
 AND plm_feature_lib.feature_name= #{featureName}
 </if>
 <if test="optionCode != null">
 AND plm_model_option.option_code= #{optionCode}
 </if>
 <if test="optionName != null">
 AND plm_option_lib.option_name= #{optionName}
 </if>

<if test="searchStr!=null and searchStr!=''">
 AND 
 CONCAT(plm_model_option.feature_code,plm_feature_lib.feature_name,plm_model_option.option_code,plm_option_lib.option_name) LIKE CONCAT ('%', #{searchStr},'%')
</if>

<select id="list" resultType="com.swkj.pojo.Member">
 SELECT *
 FROM tb_member
 WHERE 1=1
 <if test="keyword!='' and keyword!=null">
  <!--bind 标签的两个属性都是必选项， name 为绑定到上下文的变量名,value为OGNL表达式。-->
  <bind name="pattern" value="'%' + keyword + '%'"/>
  and CONCAT(username,id) like #{pattern}
 </if> 
 <if test="sdate!='' and sdate!=null">
  and starttime>=#{sdate}
 </if>
 <if test="edate!='' and edate!=null">
  and starttime&lt;=#{edate}
 </if>
 limit #{m},#{n}
 </select>
