This article mainly introduces the example analysis of Java SpringBoot rapid integration of SpringBootAdmin console monitoring services, which has a certain reference value. Interested friends can refer to it. I hope you will learn a lot after reading this article.

SpringBootAdmin is a monitoring tool for UI beautification and encapsulation of SpringBoot's Actuator interface. It can browse the basic information, detailed Health information, memory information, JVM information, garbage collection information, various configuration information (such as data source, cache list and hit rate) of all monitored spring-boot projects in the list. It can be divided into server (spring-boot-admin-server) and client (spring-boot-admin-client). Http communication is used to realize data exchange between server and client. Server-side server needs to start a separate service, while client-side client only needs to be integrated into each micro-service.

1. Know SpringBootAdmin for the first time

First of all, we need to understand that the Spring Boot Admin application can provide the following functions for us to use:

Show your health.

Show details

JVM and memory metrics

Micrometer.io index

Data source index

Cache index

Show internal number

Follow and download log files

View JVM system and environment properties

View Spring Boot configuration properties

Publishable / env-&/ refresh-endpoint that supports Spring Cloud

Easy log-level management

Interact with JMX-beans

View thread dump

View http-traces

View audit events

View http endpoints

View scheduled tasks

View and delete active sessions (using spring-session)

View Flyway / Liquibase database migration

Download heapdump

Status change notification (via email, Slack,Hipchat, etc.)

Event log for state changes (non-persistent)

2. Set up the server-add the related dependency org.springframework.boot spring-boot-starter-security org.springframework.boot spring-boot-starter-web de.codecentric spring-boot-admin-starter-server 2.5.13 in the POM file, and modify the server application startup class

Add @ EnableAdminServer annotation to our startup class to enable the SpringBootAdminServer server

@ SpringBootApplication@EnableAdminServerpublic class BootAdminServerApplication {public static void main (String [] args) {SpringApplication.run (BootAdminServerApplication.class, args);}} 4. Configure security security information

Add the following configuration information to the application.properties file.

# Application port server.port=8085# configure an account and password spring.security.user.name=adminspring.security.user.password=admin

Initialize the SecuritySecureConfig configuration (if you do not initialize, you will not see the login page with SpringBootAdmin Logo)

@ Configuration public static class SecuritySecureConfig extends WebSecurityConfigurerAdapter {private final String adminContextPath; public SecuritySecureConfig (AdminServerProperties adminServerProperties) {this.adminContextPath = adminServerProperties.getContextPath ();} @ Override protected void configure (HttpSecurity http) throws Exception {SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler (); successHandler.setTargetUrlParameter ("redirectTo") Http.authorizeRequests () .antMatrices (adminContextPath + "/ assets/**"). PermitAll () .antMatrices (adminContextPath + "/ login"). PermitAll () .anyRequest (). Authenticated () .and () .formLogin (). LoginPage (adminContextPath + "/ login"). SuccessHandler (successHandler) .and () .logout () .logoutUrl (adminContextPath + "/ logout") .and () .httpBasic () .and () .csrf () .disable () }} 5. Start server server

After the service starts, enter the following address in the browser. We can see the corresponding login page, and the corresponding account password is configured in the properties file.

Http://127.0.0.1:8085/login

After logging in, you can see that the number of applications is empty, so we need to start building our Client client.

6. Set up client client

Add the following dependency information to the pom file. (note that the version should be consistent with the server side)

De.codecentric spring-boot-admin-starter-client 2.5.1

Modify the properties file

Spring.boot.admin.client.url= http://127.0.0.1:8085spring.boot.admin.client.username=adminspring.boot.admin.client.password=adminspring.application.name=spring-boot-applicationmanagement.endpoints.web.exposure.include=*

Spring.boot.admin.client.url points to the project interface path of the server above us. Management.endpoints.web.exposure.include says all ports are exposed and can be monitored. Spring.application.name means to change the display name of the project on the spring-boot-admin.

Spring.boot.admin.client.username and password are the usernames and passwords set. It should be noted here that if security is not integrated in admin-server, you can register it without configuring a username and password, which can be monitored on the server. But if admin-server integrates security, you need to ensure that the username and password configured in client are the same as those configured in server.

After starting the client client, it will automatically register with our server server, and we can find the corresponding service through the server server application wall to view the detailed metric information. (aside from the topic: during this period, the blogger encountered that after the client started, the server could not collect the corresponding metric information. The reason is that the corresponding probe interface is not released because the client client is configured with security. If the client is useful to security, you need to release the following two API information in the security configuration. )
