Previously introduced in the Healthcheck how to add some simple health detection through metrics LIB to the system, now talk about Dropwizard metrics more important parts, record the system's measurement information. Dropwizard offers a variety of metrics: The simplest counter, the complexity of the histogram for calculating the time distribution, the meter for calculating the rate, and the timer with histo

ObjectiveIt is unavoidable to use Dropwizard as the service framework. Continuous learning. The last time you used feign in Dropwizard, using Hystrix, was a basic primer. The next step is optimization based on this. Separate the logic that needs to use the configuration from the application.In the beginning of the demo, because do not know dropwizard how to spre

The recent project uses the Dropwizard framework, the personal feeling is also good, then starts from their official website, then adds own realization step lets everybody preliminary understand this framework. The official website's definition of DW (Dropwizard) spans the boundaries between a library and a frame. His goal is to provide a reliable implementation of all the required performance of a product

not need to use the same programming language, developers can use the language they are most familiar with. This helps developers develop programs with lower costs and fewer errors. The two features of flexibility and low cost also show that these smaller programs can be reused in other projects to make them more efficient.Examples of several Java microservices frameworksHere are a few microservices frameworks that you can use for Java development: Spring Boot: This is probably the bes

simple: Simple, lightweight Good performance Stable, reliable Easy to develop and maintain I would prefer to follow the Java Specification (JSR339) framework, which is lightweight and easy to publish into Docker containers. So I will not choose Spring Boot, Spring MVC, CXF and other relatively heavy frameworks, will not choose pure netty such as too low level, but also to implement the basic functional framework such as routing.Because the pursuit of lightweight, easy

Over the past year, more and more Java frameworks have sprung up. Like JavaScript, everyone thinks they know what a good frame should be. Even my old grandmother now uses a framework that I have never heard of and may never use. Joke to joke, can do almost anything bloated frame market is saturated, but how to judge it? This article is designed to provide the best Java restfulful framework. I'm only introducing lightweight products, skipping over those bloated, overly-designed frameworks. At the

The project needs to package Dropwizard (Java restful service) and Derby (Lightweight database) into jars and then provide them for use in other projects. since Dropwizard did not provide the jar-release version, a Gradle build script was written to package Dropwizard and Derby in the Maven library into a jar package and then add it to the target project. Script

Dropwizardmetrics-basic usage Previously, healthcheck introduced how to use metrics lib to add some simple health checks to the system. Now, let's talk about the more important part of dropwizard metrics and record the measurement information of the system. Dropwizard provides a variety of measurement methods: the simplest count counter, the histogram for calculating the time distribution of complex points,

perspective of technology development, Java 8 is widely used, there is still a long way to go. Most people will continue to struggle with Java 6, so I'm going to list it. Hamcrest and Mockito are two libraries for testing. Hamcrest allows us to write assertions better, while Mockito lets us write Mock objects better. Dropwizard, we can understand a framework for developing REST services, but in fact it does nothing but integrates some existing

necessary to understand the tasks performed by each thread pool and the dependencies between them, so as to avoid deadlock problems as much as possible.SummarizeEven if the thread pool is not used directly in the application, they are most likely to be used indirectly by the application server or framework in the application. The framework for Tomcat, JBoss, Undertow, Dropwizard, and so on, provides the option to tune the thread pool (the thread pool

want to develop the internet of things, the Java language is everywhere.Thousands of developers, hundreds of consulting firms, and most of the world's top 2000 companies, are developing Java and owning a lot of Java assets.Is it the coolest language with the latest features? No, but each Java version brings together the essence of the existing language. I like Scala,go and node. js. But when I wanted to write a program that everyone could read and run on every platform (for example, the ubiquit

to isolate the thread pool used by each service. In this mode, there is still an assigned thread pool that dispatches the task to a different backend request thread pool. The thread pool may be transferred to the thread pools in the slow backend of the request because of a slow backend and no load.In addition, the multithreaded pool mode also needs to avoid deadlock problems. Deadlocks can occur if each thread is blocked on the result of waiting for an unhandled request. Therefore, in multithre
