mybatisplus trim

MyBatis-Plus is a popular Java persistence framework that extends the functionality of MyBatis. It provides several additional features and simplifies the development process.

To answer your question about the "trim" function in MyBatis-Plus, it is used to remove leading and trailing white spaces from a string before performing a comparison or operation. The "trim" function is often used in SQL queries to improve search accuracy and performance.

In MyBatis-Plus, you can utilize the "trim" function in various ways. For example, you can use it within the "where" tag to remove white spaces from a specific column value before comparing it with another value. Here's an example:

QueryWrapper<User> wrapper = new QueryWrapper<>();
wrapper.eq("name", "John").and(qw -> qw.trim("age").eq(25));

In this example, the "trim" function is used to remove white spaces from the "age" column value before comparing it with 25.

Besides the "trim" function, MyBatis-Plus provides many other useful features and utilities that can make your data access layer implementation more convenient and efficient.
