启动类

添加注解 @EnableAdminServer

import de.codecentric.boot.admin.server.config.EnableAdminServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@EnableAdminServer
@SpringBootApplication
public class AdminServerApplication {

 public static void main(String[] args) {
     SpringApplication.run(AdminServerApplication.class, args);
 }

}

SecuritySecureConfig

新建SecuritySecureConfig配置服务端安全登录。

import de.codecentric.boot.admin.server.config.AdminServerProperties;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler;

/**

 */
@Configuration
public 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()
                .antMatchers( adminContextPath + "/assets/**" ).permitAll()
                .antMatchers( adminContextPath + "/login" ).permitAll()
                .anyRequest().authenticated()
                .and()
                .formLogin().loginPage( adminContextPath + "/login" ).successHandler( successHandler ).and()
                .logout().logoutUrl( adminContextPath + "/logout" ).and()
                .httpBasic().and()
                .csrf().disable();
    }
}

server.port=8000
spring.security.user.name=admin
spring.security.user.password=admin

客户端

客户端使用较为简单引入

 		<dependency>
            <groupId>de.codecentricgroupId>
            <artifactId>spring-boot-admin-starter-clientartifactId>
        dependency>

在application.properties

# 监控
spring.application.name=WebAdmin-Client
spring.boot.admin.client.url=http://localhost:8000
#用户名密码是与服务端一致，否则不能正常监控出现401
spring.boot.admin.client.username=admin
spring.boot.admin.client.password=admin
management.endpoints.web.exposure.include=*  #监控所有端点

运行

同时启动客户端服务端

• http://localhost:8000

打开浏览器输入用户名密码

结束

会出现的异常
java.lang.IllegalStateException: Calling [asyncError()] is not valid for a request with Async state [MUST_DISPATCH]
解决方式就是更换tomcat，使用jetty,或者undertow
