Workaround: 1. Check the XML header file and the right-click property for the same encoding 2. Try to add the following configuration to the Pom.xml:

<build>  
<resources>  
    <resource>  
        <directory>src/main/resources</directory >  
        <filtering>true</filtering>  
    </resource>  
</resources>  
  
<plugins >  
    <plugin>  
        <groupId>org.apache.maven.plugins</groupId>  
        <artifactId> maven-resources-plugin</artifactid>  
        <configuration>  
            <encoding>utf-8</encoding >  
        </configuration>  
    </plugin>  
             </plugins>  
</build>  

On this basis, add a few considerations, if the configuration to ensure that the following is not a problem, or not, use the same way:

1: Check workspace working directory encoding is not UTF-8

2: Check the code of the project

3: Check if the encoding of the. xml file matches the header encoding of the XML file

The basic configuration of these three items, will not appear above problems.
