前言
本文主要給大家分享了關(guān)于spring cloud的入門教程,主要介紹了config配置的相關(guān)內(nèi)容,下面話不多說了,來一起看看看詳細(xì)的介紹吧。
簡介
Spring cloud config 分為兩部分 server client
config-server
創(chuàng)建config-server
首先創(chuàng)建config-server工程.
文件結(jié)構(gòu):
├── config-server.iml ├── pom.xml └── src ├── main │ ├── java │ │ └── com │ │ └── lkl │ │ └── springcloud │ │ └── config │ │ └── server │ │ └── Application.java │ └── resources │ ├── application.properties │ └── bootstrap.properties └── test └── java
pom.xml內(nèi)容:
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.2.3.RELEASE</version> <relativePath /> <!-- lookup parent from repository --> </parent> <groupId>com.lkl.springcloud</groupId> <artifactId>spring-cloud-config-server</artifactId> <version>1.0-SNAPSHOT</version> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-config</artifactId> <version>1.0.4.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-config</artifactId> </dependency> <!--表示為web工程--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!--暴露各種指標(biāo)--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-config-server</artifactId> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
創(chuàng)建啟動類
Application.Java
package com.lkl.springcloud.config.server; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.cloud.config.server.EnableConfigServer; import org.springframework.context.annotation.Configuration; import org.springframework.web.bind.annotation.RestController; /** * Created by liaokailin on 16/4/28. */ @Configuration @EnableAutoConfiguration @RestController @EnableConfigServer public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } }
其中 @EnableConfigServer為關(guān)鍵注解
在resources文件下創(chuàng)建application.properties
server.port=8888
配置工程監(jiān)聽端口8888,默認(rèn)情況下client通過讀取http://localhost:8888獲取配置信息
創(chuàng)建bootstrap.properties
spring.cloud.config.server.git.uri: https://github.com/liaokailin/config-repo
該配置信息通過fork https://github.com/spring-cloud-samples/config-repo (本地下載)得到
通過spring.cloud.config.server.Git.uri
指定配置信息存儲的git地址
運(yùn)行config-server
spring boot工程很方便啟動,運(yùn)行Application.java即可
獲取git上的資源信息遵循如下規(guī)則:
/{application}/{profile}[/{label}] /{application}-{profile}.yml /{label}/{application}-{profile}.yml /{application}-{profile}.properties /{label}/{application}-{profile}.properties
application:表示應(yīng)用名稱,在client中通過spring.config.name
配置
profile:表示獲取指定環(huán)境下配置,例如開發(fā)環(huán)境、測試環(huán)境、生產(chǎn)環(huán)境 默認(rèn)值default,實(shí)際開發(fā)中可以是 dev、test、demo、
production等
label: git標(biāo)簽,默認(rèn)值master
如果application名稱為foo,則可以采用如下方式訪問:
http://localhost:8888/foo/default
http://localhost:8888/foo/development
只要是按照上面的規(guī)則配置即可訪問.
config-client
創(chuàng)建config-client
目錄結(jié)構(gòu)如下:
├── pom.xml ├── spring-cloud-config-client.iml └── src ├── main │ ├── java │ │ └── com │ │ └── lkl │ │ └── springcloud │ │ └── config │ │ └── client │ │ └── Application.java │ └── resources │ └── bootstrap.yml └── test └── java
pom.xml
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.lkl.springcloud</groupId> <artifactId>spring-cloud-config-client</artifactId> <version>1.0-SNAPSHOT</version> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.2.3.RELEASE</version> <relativePath /> <!-- lookup parent from repository --> </parent> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-parent</artifactId> <version>1.0.1.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-config-client</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <repositories> <repository> <id>spring-milestones</id> <name>Spring Milestones</name> <url>http://repo.spring.io/milestone</url> <snapshots> <enabled>false</enabled> </snapshots> </repository> </repositories> <pluginRepositories> <pluginRepository> <id>spring-milestones</id> <name>Spring Milestones</name> <url>http://repo.spring.io/milestone</url> <snapshots> <enabled>false</enabled> </snapshots> </pluginRepository> </pluginRepositories> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
創(chuàng)建啟動類Application.java
package com.lkl.springcloud.config.client; import org.springframework.beans.factory.annotation.Value; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; /** * Created by liaokailin on 16/4/28. */ @SpringBootApplication @RestController public class Application { @Value("${name:World!}") String bar; @RequestMapping("/") String hello() { return "Hello " + bar + "!"; } public static void main(String[] args) { SpringApplication.run(Application.class, args); } }
創(chuàng)建bootstrap.properties文件,其內(nèi)容如下:
spring.application.name: foo spring.cloud.config.env:default spring.cloud.config.label:master spring.cloud.config.uri:http://localhost:8888
其中 spring.application.name
為應(yīng)用名稱,spring.cloud.config.uri
配置config-server暴露的獲取配置接口,其默認(rèn)值為http://localhost:8888
第二三項(xiàng)配置在前面已經(jīng)提到過,配置的都為默認(rèn)值,因此bootstrap.properties
只需要配置應(yīng)用名即可.
運(yùn)行config-client
訪問 http://localhost 得到 `Hello liaokailin` 獲取到git上的配置信息
訪問 http://localhost/env 得到所有的配置信息,可以發(fā)現(xiàn)獲取配置信息成功.
{ profiles: [ ], configService:https://github.com/liaokailin/config-repo/foo.properties: { name: "liaokailin", foo: "devoxxfr" }, configService:https://github.com/liaokailin/config-repo/application.yml: { info.description: "Spring Cloud Samples--lkl", info.url: "https://github.com/spring-cloud-samples", eureka.client.serviceUrl.defaultZone: "http://localhost:8761/eureka/" }, commandLineArgs: { spring.output.ansi.enabled: "always" }, servletContextInitParams: { }, ...}
ok ~ it's work ! more about is here(本地下載)
