2025-04-10 126 0

介绍

在当今复杂的分布式系统架构中，高效的监控至关重要。Spring Boot Admin、Spring Cloud 与 Nacos 强强联合，可快速为我们项目带来轻量级的可视化监控的理想方案。本文将详细剖析这三者的集成要点与实践细节，助您构建稳固且可控的微服务体系。

Spring cloud Admin Server 配置

1. 创建 `spring-cloud-admin-server` 项目

在 pom.xml 中添加依赖：

<dependencies>
    <!-- Spring Boot Admin Server -->
    <dependency>
        <groupId>de.codecentric</groupId>
        <artifactId>spring-boot-admin-starter-server</artifactId>
        <version>2.3.1</version>
    </dependency>
    <!-- Spring Cloud Starter Alibaba Nacos Discovery -->
    <dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        <version>2.2.6.RELEASE</version>
    </dependency>
    <!-- Spring Cloud Starter -->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter</artifactId>
        <version>2.2.6.RELEASE</version>
    </dependency>
</dependencies>

2. 配置 `application.yml`

server:
  port: 8081

spring:
  application:
    name: spring-boot-admin-server
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
management:
  endpoints:
    web:
      exposure:
        include: "*"
  endpoint:
    health:
      show-details: always

3. 启用 Spring Boot Admin Server

在主应用类上添加 @EnableAdminServer 注解：

package com.hushow.demo;

import de.codecentric.boot.admin.server.config.EnableAdminServer;
import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@Slf4j
@EnableAdminServer
@SpringBootApplication(scanBasePackages = {"com.hushow.demo.**"})
public class AdminUiApplication {
    public static void main(String[] args) {
        SpringApplication.run(AdminUiApplication.class, args);
    }

}

Spring Boot Admin Client 配置

1. 创建 `spring-cloud-admin-client` 项目

在 pom.xml 中添加依赖：

<dependencies>
    <!-- Spring Boot Admin Client -->
    <dependency>
        <groupId>de.codecentric</groupId>
        <artifactId>spring-boot-admin-starter-client</artifactId>
        <version>2.3.1</version>
    </dependency>
    <!-- Spring Cloud Starter Alibaba Nacos Discovery -->
    <dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        <version>2.2.6.RELEASE</version>
    </dependency>
    <!-- Spring Cloud Starter -->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter</artifactId>
        <version>2.2.6.RELEASE</version>
    </dependency>
    <!-- Spring Boot Actuator -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
</dependencies>

2. 配置 `application.yml`

server:
  port: 8082

spring:
  application:
    name: spring-cloud-admin-client
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
management:
  endpoints:
    web:
      exposure:
        include: "*"
  endpoint:
    health:
      show-details: always

#通过nacos发现，不需要指标admin注册中心了
#spring.boot.admin.client.url: http://localhost:8080

3. 创建主应用类

package com.hushow.demo;

import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@Slf4j
@SpringBootApplication(scanBasePackages = {"com.hushow.demo.**"})
public class AdminClientApplication {
    public static void main(String[] args) {
        SpringApplication.run(AdminClientApplication.class, args);
    }

}
