Mybatis-plus深入开发（详解${ew.sqlSegment} 与 ${ew.customSqlSegment}）

sqlSegment:

<where> ${ew.sqlSegment} </where>

customSqlSegment:

${ew.customSqlSegment} 则省略 <where></where>

eg: select * from a<where> ${ew.sqlSegment} </where>

select * from a ${ew.customSqlSegment}

注：对应dao方法中 一样要指定@Param(Constants.WRAPPER) Wrapper<User> ew,其中Constants.WRAPPER="ew"可以在源码中看到
