JPA persistence XML in the syntax of the error:

<property name= "Hibernate.connection.url" value= "jdbc:mysql://localhost:3306/test?useunicode=true& Characterencoding=utf-8 "/>

The correct wording:

<property name= "Hibernate.connection.url" value= "jdbc:mysql://localhost:3306/test?useunicode=true&amp; Characterencoding=utf-8 "/>

The following types of characters are escaped in the XML file:

&lt;	<	Less than sign
&gt;	>	Greater than sign
&amp;	&	And
&apos;	‘	Single quotation marks
&quot;
