最近在找一个spring cloud的监控组件，要求粒度要到每一个接口的，hystrix dashboard显然不适合，也不是这个应用场景。后来发现了spring boot admin这个神器，可以注册到Eureka和spring cloud无缝整合，页面AngularJS写的还算凑合，里面包含有许多功能：

显示 name/id 和版本号
    
    显示在线状态
    
    Logging日志级别管理
    
    JMX beans管理
    
    Threads会话和线程管理
    
    Trace应用请求跟踪
    
    应用运行参数信息，如：
    
    Java 系统属性
    
    Java 环境变量属性
    
    内存信息
    
    Spring 环境属性

好了，不多说，直接上和eureka整合的代码，它可以通过eureka注册表里面的信息来对每一个服务进行监控。

**1、构建service-admin工程，pom如下：**

<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>com.lovnx</groupId>
        <artifactId>micro-service</artifactId>
        <version>0.0.1-SNAPSHOT</version>
      </parent>
      <artifactId>service-admin</artifactId>
      <packaging>jar</packaging>
    
        <properties>
            <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
            <java.version>1.7</java.version>
        </properties>
    
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                 <artifactId>spring-cloud-starter-eureka</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-actuator</artifactId>
            </dependency> 
            <dependency>
                <groupId>de.codecentric</groupId>
                <artifactId>spring-boot-admin-server</artifactId>
                <version>1.4.6</version>
            </dependency>
            <dependency>
                <groupId>de.codecentric</groupId>
                <artifactId>spring-boot-admin-server-ui</artifactId>
                <version>1.4.6</version>
            </dependency>
            <dependency>
                <groupId>org.jolokia</groupId>
                <artifactId>jolokia-core</artifactId>
            </dependency> 
        </dependencies>
    
            <dependencyManagement>
            <dependencies>
                <dependency>
                    <groupId>org.springframework.cloud</groupId>
                    <artifactId>spring-cloud-dependencies</artifactId>
                    <version>Camden.SR5</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
            </dependencies>
        </dependencyManagement>
    
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>
    </project>

**2、启动主类：**

package com.lovnx;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
    import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
    import org.springframework.context.annotation.Configuration;
    
    import de.codecentric.boot.admin.config.EnableAdminServer;
    
    @Configuration
    @EnableAutoConfiguration
    @EnableDiscoveryClient
    @EnableAdminServer
    public class SpringBootAdminApplication {
        public static void main(String[] args) {
            SpringApplication.run(SpringBootAdminApplication.class, args);
        }
    }

**3、配置文件application.properties：**

server.port=7088
    spring.application.name=service-admin
    eureka.client.serviceUrl.defaultZone=http://localhost:7070/eureka/
    management.security.enabled=false
    info.version=@project.version@

**4、logback.xml(实现日志级别修改功能)：**

**5、启动：**  
![这里写图片描述][SouthEast]  
![这里写图片描述][SouthEast 1]  
![这里写图片描述][SouthEast 2]  
![这里写图片描述][SouthEast 3]  
![这里写图片描述][SouthEast 4]

**6、注意：**  
如果要监控注册到eureka的服务，必须要在这个服务里面引入：

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-actuator</artifactId>
            </dependency>

来开启一些管理功能，且须在配置文件加入一句：

management.security.enabled=false

关闭安全验证。
