监控示例
在这个示例中,我们将使用Spring Boot Actuator和Spring Cloud Security来监控应用程序的安全性。我们将创建一个名为SecurityMonitor的类来处理监控事件记录。以下是一个简单的示例:
代码语言:javascript复制@Component
public class SecurityMonitor implements HealthIndicator {
@Autowired
private SecurityMetrics securityMetrics;
@Override
public Health health() {
Map<String, Object> details = new HashMap<>();
details.put("login.count", securityMetrics.loginCounter.count());
details.put("session.time.max", securityMetrics.sessionTimer.max(TimeUnit.MILLISECONDS));
details.put("session.time.mean", securityMetrics.sessionTimer.mean(TimeUnit.MILLISECONDS));
return Health.status("UP")
.withDetails(details)
.build();
}
}
在上面的示例中,我们创建了一个名为SecurityMonitor的类,它实现了HealthIndicator接口。我们注入了名为securityMetrics的SecurityMetrics实例,并使用它来获取度量指标。然后,我们使用这些度量指标来创建健康状态,并将其返回给Actuator。
最后,我们需要在Spring Boot应用程序中启用Actuator和安全性监控。以下是一个简单的示例:
代码语言:javascript复制@SpringBootApplication
@EnableWebSecurity
@EnablePrometheusMetrics
public class Application extends WebSecurityConfigurerAdapter {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Autowired
private SecurityMonitor securityMonitor;
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/public/**").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login")
.permitAll()
.and()
.logout()
.logoutSuccessUrl("/login?logout")
.permitAll()
.and()
.csrf().disable();
}
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth
.inMemoryAuthentication()
.withUser("user").password("{noop}password").roles("USER")
.and()
.withUser("admin").password("{noop}password").roles("USER", "ADMIN");
}
@Bean
public SecurityMetrics securityMetrics() {
return new SecurityMetrics();
}
@Bean
public MetricsConfigurerAdapter metricsConfigurerAdapter() {
return new MetricsConfigurerAdapter() {
@Override
public void configureReporters(MetricRegistry metricRegistry) {
ConsoleReporter.forRegistry(metricRegistry)
.convertRatesTo(TimeUnit.SECONDS)
.convertDurationsTo(TimeUnit.MILLISECONDS)
.build()
.start(10, TimeUnit.SECONDS);
}
};
}
@Bean
public ServletContextInitializer initializer() {
return servletContext -> {
// Register the Metrics Servlet
MetricsServlet metricsServlet = new MetricsServlet();
ServletRegistration.Dynamic servletRegistration = servletContext.addServlet("metrics", metricsServlet);
servletRegistration.addMapping("/metrics/*");
// Register the Metrics Filter
FilterRegistration.Dynamic filterRegistration = servletContext.addFilter("metricsFilter", new InstrumentedFilter());
filterRegistration.addMappingForUrlPatterns(EnumSet.of(DispatcherType.REQUEST), false, "/*");
// Register the Prometheus Exporter
ExporterRegistrationListener exporterRegistrationListener = new ExporterRegistrationListener(securityMetrics());
servletContext.addListener(exporterRegistrationListener);
};
}
@Bean
public PrometheusEndpoint prometheusEndpoint() {
return new PrometheusEndpoint();
}
@Bean
public HealthIndicator securityMonitor() {
return securityMonitor;
}
}
在上面的示例中,我们创建了一个名为securityMonitor的HealthIndicator,它使用SecurityMetrics来获取度量指标并将其转换为健康状态。我们还配置了一个ServletContextInitializer来注册Metrics Servlet、Metrics Filter和Prometheus Exporter。最后,我们使用@Bean注释将这些组件注入Spring容器中。
