mybatis example $ sql注入

MyBatis provides various features to prevent SQL injection attacks. Here are a few examples:

1. Parameterized queries: MyBatis uses parameterized queries, which separate the SQL code from the user input. This approach helps prevent SQL injection by treating user input as parameters rather than concatenating them directly into the SQL statement.

2. Dynamic SQL tags: MyBatis allows the use of dynamic SQL tags, such as `<if>`, `<choose>`, and `<foreach>`, which help in constructing SQL queries dynamically. These tags automatically handle proper escaping and parameterization of user input.

3. Type handlers: MyBatis employs type handlers to convert Java types to and from database types. These handlers ensure that user input is properly escaped or sanitized when passing it to the database, minimizing the risk of SQL injection attacks.

It is important to properly utilize these features and follow best practices when using MyBatis to prevent SQL injection vulnerabilities.
