Advice deploying war files vs executable jar with embedded container

问题 There seems to be a current trend in java space to move away from deploying java web applications to a java servlet container (or application server) in the form of a war file (or ear file) and instead package the application as an executable jar with an embedded servlet/HTTP server like jetty. And I mean this more so in the way newer frameworks are influencing how new applications are developed and deployed rather than how applications are delivered to end users (because, for example, I get

Can I have multiple configuration files in DropWizard?

I want to have several yaml files for DropWizard. One of them contain sensitive info and one non sensitive. Can you point me to any docs or example how to have multiple configurations in DropWizard? ConfigurationSourceProvider is your answer. bootstrap.setConfigurationSourceProvider(new MyMultipleConfigurationSourceProvider()); The following is how dropwizard does it by default . You can easily change it to your own liking. public class FileConfigurationSourceProvider implements ConfigurationSourceProvider { @Override public InputStream open(String path) throws IOException { final File file =

Dropwizard file upload

I have to upload a file from my site yet cnt seem to get it working with drop wizard. Here is the form from my site. <form enctype="multipart/form-data" method="POST" action="UploadFile"> <input type="file" id="fileUpload" name="file"/> <input type="hidden" id="fileName" name="fileName"/> <input type="submit" value="Upload"/> </form> How would I go about on the backend to receive the file? The solution was @POST @Consumes(MediaType.MULTIPART_FORM_DATA) public Response uploadFile( @FormDataParam("file") final InputStream fileInputStream, @FormDataParam("file") final FormDataContentDisposition

SIGTERM not received by java process using 'docker stop' and the official java image

此生再无相见时 提交于 2019-12-02 18:07:15
I am running a dropwizard Java application in a Docker container using the image java:7u79 based on debian/jessie . My Java application handles the SIGTERM signal to shutdown gracefully. The SIGTERM handling works perfect when I run the application without Docker. When I run it in a Docker container the SIGTERM does not reach the Java application when I issue a docker stop command. It kills the process abruptly after 10 seconds. My Dockerfile : FROM java:7u79 COPY dropwizard-example-1.0.0.jar /opt/dropwizard/ COPY example.keystore /opt/dropwizard/ COPY example.yml /opt/dropwizard/ WORKDIR /opt

Externalize Configuration Dropwizard 有许多配置内置组件(如servlet引擎或数据库数据源)的选项,以及创建可以使用配置文件运行和配置的全新命令的选项。我们还可以为那些希望根据运行环境进行更改的配置类型注入环境变量和系统属性。与SpringBoot一样,我们可以将整个属性类绑定到特定对象。在本例中,让我们将所有helloapp.*properties 绑定到 HolaRestResource 类。使用 SpringBoot,我们可以选择在带有键值元组的属性文件中编写配置文件。我们也可以使用YAML。对于 Dropwizard,我们只有YAML选项。 因此,让我们在根项目中创建一个名为conf/applica-tion.yml的文件(注意,如果不存在conf目录,则需要创建该目录)。我们将配置文件放在conf文件夹中,以帮助我们组织项目的不同配置文件(目录的命名并不重要(也就是说,它对 Dropwizard 没有任何传统意义)。让我们在conf/application.yml文件中添加一些配置: 在本例中,我们将属性设置为特定值。如果我们希望能够基于某些环境条件覆盖它呢?我们可以通过传入类似于Ddw.helloapp.say=guten标记的Java系统变量来重写它。请注意,系统属性名称的dw.*部分是重要的

调用另一个服务 在微服务环境中,每个服务负责向其他协作者提供功能或服务。如果我们希望扩展“HelloWorld”微服务,我们将需要创建一个可以使用Drop向导的REST客户端功能调用的服务。就像我们为SpringBoot微服务所做的那样,我们将从随书附带的源代码中利用后端服务。交互看起来类似于: 如果您查看这本书的源代码,我们将看到一个名为Backend的Maven模块,它包含一个非常简单的HTTPservlet,可以通过GET请求和查询参数调用它。此后端的代码非常简单,并且不使用任何框架(SpringBoot、Swarm或 WildFlySwarm)。 要在端口8080上启动后端服务,在目录并运行以下命令: 该服务在/api/backend 开放,并接受一个查询参数。例如,当我们使用以下路径/API/backend?greeting=Hello时,后端服务将使用如下所示的JSON对象进行响应: $ curl -X GET http://localhost:8080/api/backend?greeting=Hello 在我们开始之前,让我们添加下 dropwizard-client 依赖项到我们的 por.xml 中: <dependency> <groupId>io.dropwizard</groupId> <artifactId>dropwizard-client<

Getting Started Dropwizard 没有任何花哨的项目初始化助手或Maven插件。开始使用Dropwizard 时,遵循与任何普通Java项目类似的模式:使用Maven原型,或者使用当前使用的任何工具将其添加到现有应用程序中。您还可以使用JBoss Forge,这是一个与技术无关的Java项目协调和管理工具,它允许您快速创建项目、添加依赖项、添加类等等。在本节中,我们将使用Maven archetypes。 选择要在其中创建新的 Dropwizard 项目的目录。还要验证是否安装了Maven。您可以从操作系统的命令提示符运行命令,也可以使用以下命令中的下列信息填充您喜欢的IDE的对话框或向导: 导航到Maven原型生成器在 hola-dropwizard 中为我们提供的目录,并运行以下命令来构建我们的项目: 你将会成功地构建! 这使用 Dropwizard 原型 java-Simple 来创建我们的微服务。如果进入hola-dropwizard 目录,应该会看到以下结构: 请注意,Dropwizard 为您创建了一个遵循其约定的包结构: api 定义在REST资源中使用的对象的POJO(有些人将这些对象称为域对象或DTO)。 cli 这就是 Dropwizard 命令的去处(希望添加到应用程序启动过程中的其他命令)。 client Client helper

Logging into different files based on some condition

偶尔善良 提交于 2019-12-02 09:49:58
We have an application. In which we have a condition.Based on the condition, if it is true then we will write some log messages to one file else we will log the messages to another file. And logging should be happened based on the condition and not based on log level. How it is possible in dropwizard using yaml file? This is supported out of the box. Here is my example: server: rootPath: /api/* requestLog: appenders: [] applicationConnectors: - type: http port: 9085 logging: level: INFO loggers: "my-log-1": level: DEBUG additive: false appenders: - type: file currentLogFilename: /home/artur
