使用 jpackage 构建我的 JavaFX 应用程序后数据库错误连接

问题描述

我正在使用 MysqL 数据库 (AWS) 开展 JavaFX 项目。当我从 Intellij 启动我的项目时,它运行良好,但是当我尝试使用 jpackage 和 build.gradle 导出、安装和启动我的应用程序时,我获得了一个包含以下错误的窗口:

com.MysqL.cj.jdbc.exceptions.communicationsexception communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The drive has not received any packets from server.

我不明白问题出在哪里。所有连接都通过 AWS 授权到我的数据库,jpackage 进程运行没有错误,正如我之前所说,当我从 IntelliJ 启动时它运行良好。

这是我的 build.gradle

plugins {
    id 'java'
    id 'application'
    id 'org.openjfx.javafxplugin' version '0.0.9'
    id 'org.beryx.runtime' version '1.11.3'

    mavenCentral()

    version = "15.0.1"
    modules = [ 'javafx.controls','javafx.fxml' ]

    manifest {
        attributes 'Main-Class': 'com.github.studeasy.launcher.appMain'
    }
}

application {
    mainClassName= "com.github.studeasy.launcher.appMain"
    applicationName = 'StudEasy'
}


javadoc {
    source = sourceSets.main.allJava
    classpath = sourceSets.main.runtimeClasspath
}

test {
    useJUnitPlatform()
}

runtime {
    options = ['--strip-debug','--compress','2','--no-header-files','--no-man-pages']
    launcher {
        noConsole = false
    }
    jpackage {
        def currentOs = org.gradle.internal.os.OperatingSystem.current()
        def imgType = currentOs.windows ? 'ico' : currentOs.macOsX ? 'icns' : 'png'
        imageOptions += ['--icon',"src/main/resources/images/logo.$imgType"]
        installerOptions += ['--resource-dir',"src/main/resources"]
        installerOptions += ['--vendor','Stud Easy']
        if(currentOs.windows) {

        }
        else if (currentOs.linux) {
            installerOptions += ['--linux-package-name','StudEasy','--linux-shortcut']
        }
        else if (currentOs.macOsX) {
            installerOptions += ['--mac-package-name','StudEasy']
        }
    }
}
