Maven配置文件，使用休眠配置文件进行资源过滤

Question

I am trying to instantiate hibernate configuration file using maven profiles. My config file resides under src/main/resources and in the pom file I marked that folder to be used in resource filtering. Interestingly I can load the same properties from properties file whereas hibernate throws exception while parsing config file. Here is the code samples I am using.

POM - Resource Filtering

<resources>
    <resource>
         <directory>src/main/resources</directory>
         <filtering>true</filtering>
    </resource>
</resources>

File structure

src/main/resources/hibernate.cfg.xml

src/main/resources/hibernate.properties

Maven dev profile

<profile>
    <id>dev</id>
    <properties>
            <hibernate.connection.url>jdbc:mysql://localhost:3306/example_schema?zeroDateTimeBehavior=convertToNull&amp;UseUnicode=true&amp;characterEncoding=utf8</hibernate.connection.url>
    </properties>
</profile>

Hibernate config file sample

<property name="hibernate.connection.url">${hibernate.connection.url}</property>

Properties file sample

hibernate.config.file = ${hibernate.config.file}

When I run my application I see that the properties file is filled with correct values; but hibernate config file throws following parse exceptions.

Caused by: org.dom4j.DocumentException: Error on line 1 of document : Content is not allowed in prolog. Nested exception: Content is not allowed in prolog. at org.dom4j.io.SAXReader.read(SAXReader.java:482) at org.hibernate.cfg.Configuration.doConfigure(Configuration.java:2155)

and from same stack trace

The reference to entity "UseUnicode" must end with the ';' delimiter. Nested exception: The reference to entity "UseUnicode" must end with the ';' delimiter.

But in the pom I already escape & with & . When I remove query params from url it works as I expect, how can I escape ampersand from pom file?
