  • SpringBoot集成Consul服务接入配置中心

    闲话少谈,直奔主题

    一、我的研发环境

    springboot:2.1.8.RELEASE

    spring.cloud:Greenwich.SR5

    二、POM文件展示

    <?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 https://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>2.1.8.RELEASE</version>
            <relativePath/> <!-- lookup parent from repository -->
        </parent>
       ....
       ....
       ....
        <properties>
            <java.version>1.8</java.version>
            <spring.boot.version>2.1.8.RELEASE</spring.boot.version>
            <spring.cloud.version>Greenwich.SR5</spring.cloud.version>
            <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        </properties>
        <dependencyManagement>
            <dependencies>
                <dependency>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-parent</artifactId>
                    <version>${spring.boot.version}</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
                <dependency>
                    <groupId>org.springframework.cloud</groupId>
                    <artifactId>spring-cloud-dependencies</artifactId>
                    <version>${spring.cloud.version}</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
            </dependencies>
        </dependencyManagement>
        <dependencies>
            <!-- 引入 Spring Cloud Consul Discovery 相关依赖,将 Consul 作为注册中心,并实现对其的自动配置 -->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-consul-discovery</artifactId>
            </dependency>
         <!-- 引入 Spring Cloud Consul Config 相关依赖,将 Consul 作为配置中心 -->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-consul-config</artifactId>
            </dependency>
            <!-- 引入 Spring Boot Actuator 组件,因为需要通过它提供健康检查的接口给 Consul -->
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-actuator</artifactId>
            </dependency>
        </dependencies>
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>
    </project>

    三、bootstrap.yaml文件的编写。(经过验证,配置中心默认加载bootstrap.(yml|yaml|properties)配置文件,完成配置中心功能的初始化)

    # consul的配置启动环境
    consul:
      host: 192.168.10.118 # 注册地址( need )
      port: 8501 # Consul 端口( need )
      acl-token: 495af318-0822-b701-ee8d-80dc6d4d863a # 访问token ( need )
    spring:
      #consul配置
      cloud:
        # Spring Cloud Consul 通用配置项,对应 ConsulProperties 类
        consul:
          host: ${consul.host} # 注册地址
          port: ${consul.port} # Consul 端口
          # consul配置中心
          config:
            prefix: config
            enabled: true
            format: YAML
            data-key: common
            acl-token: ${consul.acl-token}
          # Spring Cloud Consul Discovery 配置项,对应 ConsulDiscoveryProperties 类
          discovery:
            enabled: true
            # register: true # 注册自身到consul
            deregister: true # 服务停止时取消注册
            service-name: ${spring.application.name} # 注册到 Consul 的服务名,默认为 `spring.application.name` 配置项
            health-check-path: /actuator/health # 健康检查的接口,默认为 /actuator/health,由 Spring Boot Actuator 提供
            acl-token: ${consul.acl-token}

    四、consul的系统参数配置

    我的测试地址:http://192.168.10.118:8500/ui/rdc/kv/config/app-exchange-api/common/edit

     五、配置完成,系统启动成功读取配置......
