Objective:
Must learn to springboot basic knowledge
Brief introduction:
Spring Cloud provides developers with tools to quickly build distributed systems, including configuration management, service discovery, circuit breakers, routing, micro-proxies, event busses, global locks, decision-making campaigns, distributed sessions, and more. It runs in a simple environment and can run on a developer's computer.
Tools:
JDK8
apache-maven-3.5.2
In the previous article we described a service how to read a file from the configuration center, configuration Center How to read the configuration file from remote git, when a lot of service instances, all the files from the configuration center, you can consider the configuration center as a micro-service, clustering it to achieve high availability, the frame composition is as follows:
1: Create a new Eureka Server project, named Config-eureka-serve
Brief introductionIn the Distributed file system, because of the large number of services, in order to facilitate the unified management of service profiles, real-time updates, so the need for distributed configuration Center components. In spring cloud, there is a distributed Configuration center component, Spring Cloud Config, which enables configuration services to be placed in the memory of the configuration service (that is, local) and also in a

Any entry in the Config row is also a scope. For example, you write this:
CONFIG + + warn_on
You will get a scope called "warn_on". This will make it easy to modify the configuration in your project without losing all of the customizations that might be require
I developed a Package myself, in which Provider is used to register the service, but the config () method is used to obtain the configuration. The problem is that the config file has not been publish, I don't feel like I have a wrong idea. The code is as follows: {code ...} {code ...} then I run phparti...

Description of the problemIn addition to the normal config file, using ConfigurationManager loading, we may also encounter a situation like this:1.

IntroducedSpring Cloud Config provides server and client support for external configurations in distributed systems. With Config Server, you can manage the external properties of your application in all environments. The conceptual mappings on the client and server are the same as the spring environment and Propertysource abstractions,So they fit well with Spring applications, but can be used with any appli

High Availability of spring cloud config distributed configuration center, springcloud
In the previous article, we implemented the unified management of configuration files, but we can find that we only use one server. If this server fails, the entire configuration center will be unavailable. Next, we will solve the high availability problem of the configuration center.
The following describes how to integrate Eureka to achieve high availability of th

In most programsWeb. configAnd must be changed during deployment. It is tedious and error-prone to manual configuration changes every time. This section will tell you how to update automaticallyWeb. configFile to avoid these problems.2. Web. config Transformations and Web Deploy Parameters
There are two ways to automatically update the settings of the Web. config file: Web.
If you are still confused about the web. config configuration file in Asp.net, please refer toArticleIt will give you a brief understanding of the Asp.net runtime mechanism.

The Web. config file usually includes settings that must be different based on the running environment of the application. For example, when deploying the Web. config file, you may have to change the database connection string or disable debugging. ASP. NET provides some tools for Web application projects to automatically change (convert) The Web. config file whe
Because our development involves the local, test, and production environments, the manager recently asked to write a web. config, you can use a program to determine the current running environment, and then use a custom node to retrieve various variables in the corresponding environment, instead of maintaining them separately like preparing three different configuration files in the past.
Although I have a general idea, I still feel a little confused
The server provides resource-based HTTP for external configuration (name-value pairs or equivalent yaml content). The server can be @EnableConfigServer easily embedded in the spring boot application using annotations. So this application is a configuration server:Configserver.java@SpringBootApplication@EnableConfigServerpublic class ConfigServer { public static void main(String[] args) { SpringApplication.run(ConfigServer.class, args); }}Like all spring boot applications running on the defa
Start the server:$ cd spring-cloud-config-server $.. /MVNW Spring-boot:run The server is a spring boot application, so you can run it from the IDE instead of liking it (the main class is ConfigServerApplication ).
