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

在win下开发，有时编译或运行项目会报3字节的UTF-8序列的字节3无效。
解决该问题的办法

1、将xml头文件改为GBK编码方式
,我这里不OK

1. <?xml version="1.0" encoding="GBK"?>

2、使用Maven修改默认格式
,我这里不OK

    <build>
        <plugins>
            <!-- resource插件 -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-resources-plugin</artifactId>
                <version>2.6</version>
                <configuration>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>
        </plugins>
    </build>

3、以上如果还不可行，那么在pom.xml里加入 ,我这里不OK

1. <properties>
2. <!-- 设置默认编码 -->
3. <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
4. </properties>

4、修改bpmn文件的编码格式为UTF-8，我这里OK

用记事本打开bpmn文件，另存为utf-8编码的文件，XML也是utf-8编码格式

pom.xml文件

<?xml version="1.0" encoding="UTF-8"?>
