Spring Boot Admin是Spring Boot项目的一个社区项目，主要用于管理和监控Spring Boot应用程序。Spring Boot Admin应用分为Server应用和Client应用，其中Server应用用于收集Cient应用的信息并对其进行监控。背后的数据采集是由Actuator端点提供的。数据的采集方式主要有两种：应用程序通过HTTP协议向Spring Boot Admin Server注册信息；或者Sring Boot Admin Server通过使用服务发现（Eureka、Consul）收集Client信息。

Tomcat替换为Jetty的原因
启动后有报错

引入spring-boot-starter-security原因
Spring Boot Admin服务器可以访问应用程序的敏感端点，因此建议为管理员和客户端应用程序添加安全配置，并添加安全配置类
@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 {
// @formatter:off
SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler();
successHandler.setTargetUrlParameter("redirectTo");
successHandler.setDefaultTargetUrl(adminContextPath + "/");
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()
.csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse())
.ignoringAntMatchers(
adminContextPath + "/instances",
adminContextPath + "/actuator/**"
);
// @formatter:on
}
}
这是一个简单的安全配置，但添加后，客户端也需要进行安全设置，否则客户端信息无法注册到服务器，客户端需要增加一下配置，下文client配置将会继续提到
spring.boot.admin.username=admin
spring.boot.admin.password=admin
启动类
启动类增加@EnableAdminServer注解，用于引入Spring Boot Admin Server配置
@SpringBootApplication
@EnableAdminServer
public class AdminServerApplication {
public static void main(String[] args) {
SpringApplication.run(AdminServerApplication.class, args);
}
}
配置文件
server:
port: 8072
spring:
security:
user:
name: admin
password: 123456
测试
到这里Spring Boot Admin Server项目就配置完成了，启动项目可以看到如下页面

启动类
无需任何另外的设置
@SpringBootApplication
public class AdminClientApplication {
public static void main(String[] args) {
SpringApplication.run(AdminClientApplication.class, args);
}
}
配置文件

安全配置类
@Configuration
public class SecurityPermitAllConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity.authorizeRequests().anyRequest().permitAll().and().csrf().disable();
}
}
测试
启动client应用后，可以查看到如下图所示内容
admin-client-application
