        java.lang.IllegalStateException: The Java Virtual Machine has not been configured to use the desired default character encoding (UTF-8).

它可以固定为:添加环境变量 JAVA_TOOL_OPTION = -Dfile.encoding="UTF-8"但它不起作用。

Environment variable

在 IntelliJ Idea 设置中，所有内容都设置为 UTF-8。

应用程序属性

spring.mandatory-file-encoding=UTF-8

pom.xml

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <file.encoding>UTF-8</file.encoding>
    <java.version>1.8</java.version>
</properties>

使用 Windows 10。

我们可以通过将运行时参数传递给命令来对源编码和输出编码进行编码，如下所示:

mvn -Dproject.build.sourceEncoding=UTF-8 -Dproject.reporting.outputEncoding=UTF-8 clean deploy 

或者在pom.xml中添加一行:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <redis.version>1.3.5.RELEASE</redis.version>
</properties>
