Brief description of escape _java with mybatis greater than less

Recently, using MyBatis, and then using less than or equal, directly using <= in XML, the resulting XML file always displays a red error, as follows:

SUM (case when P.pool_year <= ' 2014 ' then P.POOL_RMB else 0) as "one",

The conjecture may have been due to special characters, and the escape character was replaced with the following:

SUM (case when P.pool_year <= ' 2014 ' then P.POOL_RMB else 0) as "one",

Log down to prevent future errors.

Common escape characters in XML:

< < less than number

> > Greater than Number

& & and

• ' Single quotes

• "" Double quotes

The above is small set to introduce the MyBatis more than less than the escape, I hope to help you, if you have any questions please give me a message, small series will promptly reply to everyone. Here also thank you very much for the cloud Habitat Community website support!
