MyBatis Empty String Check Methods

In Mybatis, you can use the

<if test="name != null and name != ''">
    <!--处理name不为空的情况-->
</if>

In the example above, name != null and name != ” means checking that name is not empty. If name is empty, it will not enter the if statement.

In addition, you can also use the isEmpty() method in the tag in Mybatis to check if a string is empty. An example is shown below:

<if test="name.isEmpty()">
    <!--处理name为空的情况-->
</if>

This makes it easy to determine empty strings in Mybatis.
