MyBatis CDATA Tag: Purpose and Usage

The purpose of the CDATA tag in MyBatis is to escape special characters in SQL statements or XML content.

Special characters such as <, >, & may appear in SQL statements or XML content in MyBatis. To prevent parsing errors or unexpected results, these special characters can be escaped by using the CDATA tag.

The format of using the CDATA tag is as follows:

The content inside the CDATA tag will be treated as text and not parsed. This ensures that special characters will not be recognized by the parser as part of an SQL statement or XML content, but rather be processed as plain text. This helps ensure that SQL statements or XML content can be correctly parsed, avoiding errors or unexpected results.

In MyBatis mapping files, you can use CDATA tags to wrap SQL statements or XML content to ensure that special characters are correctly interpreted. For example:

In the example above, the CDATA tag wraps the SQL statement to ensure that special characters within it do not cause parsing errors.
