使用spring-boot运行java应用程序，并在digitalocean

标签： java eclipse spring gradle digital-ocean

我正在尝试使用eclipse，java，gradle，spring-boot构建一个安静的服务，并将其托管在数字海洋服务器上。我想在特定端口或某物上访问数字海洋网址时获得JSON响应，因此我可以执行123.456.78：90并在浏览器中查看JSON。

当我在eclipse中运行它并访问localhost时，这很好用。访问localhost：port＃给出了所需的输出，但我注意到控制台日志与eclipse之间的差异，以及我在服务器上运行它时。

我的猜测是，出于某种原因，我的数字海洋服务器并不能与Tomcat或其他东西玩得很好。我通过ufw命令打开了端口，检查了iptables，安装了apache2（我甚至不知道我是否必须诚实）并确保配置设置为接受端口的出站和入站请求8080和8000.

我注意到我的请求方法没有被映射，这让我觉得存在一些依赖性问题。这是我的build.gradle以供参考。

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.3.1.RELEASE")

    }
}

apply plugin: 'java'
apply plugin: 'application'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot'

mainClassName = "Keen.KeenAPICallTester"
applicationDefaultJvmArgs = ["--server.port=8000"]

jar {
    baseName = '****-ML'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
}

sourceCompatibility = 1.8
targetCompatibility = 1.8



dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")
    testCompile("junit:junit")
    compile fileTree(dir: 'libs', include: '*.jar')
}

task wrapper(type: Wrapper) {
    gradleVersion = '2.3'
}

task(runSimple, dependsOn: 'classes', type: JavaExec) {
    main = 'Keen.KeenAPICallTester'
    classpath = sourceSets.main.runtimeClasspath
    args '--server.port=8000'
}

我处理这个问题的方式有问题吗？我也有一个runSimple命令，这样我就可以使用JVM端口运行，但它没有任何区别，即使我将它设置为80并直接进入默认的数字海洋IP地址。

我之前在数字海洋上运行应用程序，通常只需通过ufw打开特定端口并在端口上运行应用程序，然后通过互联网访问它。但是，我想了解的内容正在进行中。

1 个答案:

答案 0 :(得分：2)

似乎应用程序被卡住了，因为它可能正在等待public void hover_Product_Category(){ action.moveToElement(product_Category).perform(); } （阻止设备，可能已经干了）。

您可以通过启动应用程序传递JVM-param /dev/random来使用/dev/urandom。

请参阅Avoiding JVM Delays Caused by Random Number Generation

此外，要深入研究这些奇怪的问题，-Djava.security.egd=file:/dev/./urandom或jstack等工具可能会有所帮助。
