//长度
<if test="orgCode.length() == 1"></if>
//相等
<if test='taskDefKey.equals("AAA")'></if>
// 字符相等 即最外边用双引号，里边用单引号，此写法会报java.lang.NumberFormatException
<if test="stringParam != null and stringParam != 'a'"></if>
//判断存在
<if test="stringParam.indexOf('aa') != -1"></if>
//判断Integer是否大于0 gt大于,lt小于
<if test="idParam !=null and idParam gt 0"></if>
//like
<if test="title != null">
     AND  title LIKE CONCAT(CONCAT('%',#{title}),'%')
</if>
