mybatis choose标签的用法

先上代码:

 <choose>
  <when test="BEGINTIME != null and BEGINTIME != '' and ENDTIME != null and ENDTIME != ''">
     AND time BETWEEN #{BEGINTIME, jdbcType=VARCHAR} AND #{ENDTIME, jdbcType=VARCHAR}
  when>
  <when test="BEGINTIME != null and BEGINTIME != ''">
      #{BEGINTIME, jdbcType=TIMESTAMP} ]]>
  when>
  <when test="ENDTIME != null and ENDTIME != ''">

  when>
  <otherwise>otherwise>
 choose>

choose标签与if标签不同,前者之间是或(or)的关系,后者之间是与(and)的关系,choose标签类似于java中的switch语句

choose-switch

when-case

otherwise-default
