SpringBoot+SpringCloud+vue+Element开发项目——注册中心（Consul）

一、Consul安装

下载地址：https://www.consul.io/downloads.html

 

 打开CMD，进入consul.exe所在的目录，执行命令启动Consul服务。

# 进入Consul.exe所在的目录
cd C:consul_1.6.2.windows_amd64

# 启动服务，-dev表示开发模式运行，另外还有-server标识服务模式运行
consul agent -dev

启动成功后，访问http://localhost:8500

二、monitor改造

在pom.xml中添加spring cloud和consul注册中心依赖。

<!--consul-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-consul-discovery</artifactId>
        </dependency>

<!--srping cloud-->
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Finchley.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

application.yml

server:
  port: 8000
spring:
  application:
    name: jansens-monitor
  cloud:
    consul:
      host: localhost
      port: 8500
      discovery:
        serviceName: ${spring.application.name}    # 注册到consul的服务名称

修改启动类，添加@EnableDiscoveryClient注解

JansensMonitorApplication.java

@EnableAdminServer
@EnableDiscoveryClient
@SpringBootApplication
public class JansensMonitorApplication {
    public static void main(String[] args) {
        SpringApplication.run(JansensMonitorApplication.class, args);
    }
}

 

三、backup改造

在pom.xml中添加spring cloud和consul注册中心依赖。

<!--consul-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-consul-discovery</artifactId>
        </dependency>

<!--srping cloud-->
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Finchley.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

application.yml

# tomcat
server:
  port: 8002
spring:
  application:
    name: jansens-backup
  boot:
    admin:
      client:
        url: "http://localhost:8000"
  cloud:
    consul:
      host: localhost
      port: 8500
      discovery:
        serviceName: jansens-backup    # 注册到consul的服务名称
# 开放健康检查接口
management:
  endpoints:
    web:
      exposure:
        include: "*"
  endpoint:
    health:
      show-details: ALWAYS
# backup datasource
jansens:
  backup:
    datasource:
      host: localhost
      userName: root
      password: root
      database: jansens

修改启动类，添加@EnableDiscoveryClient注解

四、admin改造

 在pom.xml中添加spring cloud和consul注册中心依赖。

<!--consul-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-consul-discovery</artifactId>
        </dependency>

<!--srping cloud-->
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Finchley.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
