Cause analysis:

analysis: the main reason for this problem is that the code declared in the XML file is inconsistent with the code saved in the XML file itself
for example, your statement is & lt;?xml version=”1.0″ encoding=”UTF-8″?& gt;<However, it is encoded in ANSI format. Although there is no garbled code, the XML parser cannot parse it
the solution is to reset the consistency between the encoding and declaration when saving XML files</ font>

Solution:

Configure in pom.xml file

	<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>
