how can we set the properties of management, other properties which are related to hibernate, jpa, transactions, etc dynamically from rest api. I have tried few things here,

import javax.persistence.EntityManager; import org.hibernate.SessionFactory; import org.hibernate.stat.Statistics;

// Your endpoint that toggles the Hibernate statistics public void toggleHibernateStats(boolean enableStats) {     EntityManager entityManager = getEntityManager();     SessionFactory sessionFactory = entityManager.unwrap(SessionFactory.class);     Statistics statistics = sessionFactory.getStatistics();

// Set the Hibernate statistics property to enable or disable statistics     statistics.setStatisticsEnabled(enableStats);

// Return a response indicating whether statistics were successfully turned on or off     if (statistics.isStatisticsEnabled() == enableStats) {         return "Hibernate statistics " + (enableStats ? "enabled" : "disabled") + " successfully";     } else {         return "Failed to " + (enableStats ? "enable" : "disable") + " Hibernate statistics";     } }

@RestController public class ActuatorController {

@Autowired     private Environment environment;

@PostMapping("/actuator/properties")     public void setActuatorProperty(@RequestParam String key, @RequestParam String value) {         ((ConfigurableEnvironment) environment).getPropertySources().addFirst(new MapPropertySource(                 "runtimeProperties", Collections.singletonMap(key, value)));     } }

@RestController public class ActuatorController {

@Autowired     private EndpointProperties endpointProperties;

@PostMapping("/actuator/properties")     public void setActuatorProperty(@RequestParam String key, @RequestParam String value) {         switch (key) {             case "enabledByDefault":                 endpointProperties.setEnabledByDefault(Boolean.parseBoolean(value));                 break;             case "infoEnabled":                 endpointProperties.setInfoEnabled(Boolean.parseBoolean(value));                 break;             default:                 // handle unknown property                 break;         }     } }

And none of these reflected when i was trying to use them.

Spring Boot will generally only read and apply configuration at startup. Spring Cloud has some ability to refresh beans after startup.
