java - 如果我向 application.properties 添加任何值，Spring Boot 项目会崩溃

问题描述

我只是想将环境变量添加到我的项目中。无论我在application.properties文件中添加什么，程序都会崩溃，并且pom.xml在我的 IDE 中突然变得无效并以红色突出显示。例如：如果我将此添加到我的application.properties文件中：

my.test="hello"

然后该pom.xml文件在我的 IDE 中因错误而突出显示为红色，并且程序无法启动。

这是我的 pom 文件中的错误：

Execution default-resources of goal org.apache.maven.plugins:maven-resources-plugin:3.2.0:resources failed: newPosition < 0: (-1 < 0) (org.apache.maven.plugins:maven-resources-plugin:3.2.0:resources:default-resources:process-resources)

解决方案

我认为你的编码有问题。尝试添加到你的 pom next 属性：

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