Mybatis测试中出现错误： 1 字节的 UTF-8 序列的字节 1 无效

在Mybatis测试中遇到的两个错误

一、Error building SqlSession.

Cause: org.apache.ibatis.builder.BuilderException: Error creating document instance. Cause: com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequenceException: 1 字节的 UTF-8 序列的字节 1 无效。

从错误信息中提取到信息---->1 字节的 UTF-8 序列的字节 1 无效。

解决方法

将所有配置信息中的UTF-8改为UTF8

二、还有可能出现以下的错误，value="com.mysql.jdbc.Driver"，将其改为value="com.mysql.cj.jdbc.Driver"就ok了

三、还有一种方法，在pom.xml文件中配置

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