此外，信息和健康点在actuator中默认是启用的，您不需要手动公开它们。当您将依赖项添加到pom.xml时，它将被启用，您可以访问url端点而无需公开它们

这个例子使用HealthContributorRegistry来检索HealthIndicator的名称。它还考虑了CompositeHealthContributors。

import org.springframework.boot.actuate.health.CompositeHealthContributor;
import org.springframework.boot.actuate.health.HealthContributor;
import org.springframework.boot.actuate.health.HealthContributorRegistry;
import org.springframework.boot.actuate.health.HealthIndicator;
import org.springframework.boot.actuate.health.NamedContributor;
import org.springframework.stereotype.Service;

@Service
public class CustomHealthService {
    private final HealthContributorRegistry healthContributorRegistry;

    public CustomHealthService(HealthContributorRegistry healthContributorRegistry) {
        this.healthContributorRegistry = healthContributorRegistry;
    }

    public void printHealth() {
        healthContributorRegistry.forEach(this::printHealthIndicatorStatus);
    }

    private void printHealthIndicatorStatus(NamedContributor<HealthContributor> contributor) {
        if (contributor.getContributor() instanceof HealthIndicator) {
            System.out.println("Health indicator '" + contributor.getName() + "' has health: '" + ((HealthIndicator) contributor.getContributor()).health() + "'");
        } else if (contributor.getContributor() instanceof CompositeHealthContributor) {
            ((CompositeHealthContributor) contributor.getContributor()).forEach(this::printHealthIndicatorStatus);
        } else {
            throw new RuntimeException("Unexpected HealthContributor type " + contributor.getClass().getName());
        }
    }
}

也许有更好的方法来获得健康数据，但这对我很有效。

@RestController
public class HealthController {
    @Autowired
    HealthContributor[] healthContributors;
    
    
    @GetMapping("/health")
    public Map<String, String> health() {
        Map<String, String> components = new HashMap<String, String>();
        for(HealthContributor healthContributor : healthContributors) {
            String componentName = healthContributor.getClass().getSimpleName().replace("HealthIndicator", "").replace("HealthCheckIndicator", "");
            String status = ((HealthIndicator)(healthContributor)).health().getStatus().toString();
            //To get details
            //Map<String,Object> details = ((HealthIndicator)(healthContributor)).health().getDetails();
            
            components.put(componentName, status);
            
        }
        return components;
    }
    
}

输出示例：

{
  "Mail":"UP",
  "Ping":"UP",
  "Camel":"UP",
  "DiskSpace":"UP"
}

要模拟HealthContributor []，您可以尝试使用Mockito如下：

@Profile("test")
@Configuration
public class HealthContributorsMockConfig {

    @Primary
    @Bean(name = "healthContributors")
    public HealthContributor[] healthContributors() {
        HealthContributor[] healthContributors = new HealthContributor[2];
        
        HealthContributor healthContributorA = Mockito.mock(HealthIndicator.class, new Answer<Object>() {

            @Override
            public Object answer(InvocationOnMock invocation) throws Throwable {
                // TODO Auto-generated method stub
                Health health = Health.up().build();
                return health;
            }
            
        });
        
        HealthContributor healthContributorB = Mockito.mock(HealthIndicator.class, new Answer<Object>() {

            @Override
            public Object answer(InvocationOnMock invocation) throws Throwable {
                // TODO Auto-generated method stub
                Health health = Health.down().build();
                return health;
            }
            
        });
        
        healthContributors[0] = healthContributorA;
        healthContributors[1] = healthContributorB;
        return healthContributors;
        
    }
}

当然，您可以注入相应的Endpoint。例如，如果您对HealthEndpoint感兴趣，您可以：

@RestController
public class ActuatorController {

    private final HealthEndpoint healthEndpoint;

    public ActuatorController(HealthEndpoint healthEndpoint) {
        this.healthEndpoint = healthEndpoint;
    }

    @GetMapping("health")
    public String health() {
        return healthEndpoint.health().getStatus().getCode();
    }
}
