Special Character Processing and special symbols in mybatis xml, mybatisxml

The following describes how to process special characters in mybatis xml. The specific content is as follows:

1. CDATA zone:

It is called character data, with "<! [CDATA ["starts with"]> "ends. embed the original data that you do not want to be parsed by the parser between the two. The parser does not parse the content in the CDATA area, instead, the data is handed over to downstream programs for processing.

2, special characters:

In xml, <= less than or equal to,> = greater than or equal to: <! [CDATA []> the & Symbol in xml is required.

<! [CDATA [&]> &

<= Less than or equal to: <! [CDATA [<=]>

>=Greater than or equal to: <! [CDATA [>=]]>

3. Some special characters can also be replaced by the following replacement symbols.
