MalformedByteSequenceException:3 字节的 UTF-8 序列的字节 3 无效。

错误如下：

解决办法：

1.检查xml的头文件和右键属性里面的编码是否一致

2.尝试在pom.xml加入如下配置：

   <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>
