博客主要介绍了MongoDB的相关配置操作，包括进行自定义配置，可加入监听器并修改其他配置，还提到增加集群监听器和server监听器。

1.自定义配置：这里是加入监听器，也可以修改mogodb其他配置

@Configuration
public class MongoConfig extends MongoAutoConfiguration {

    private MongoClientOptions options;

    private final MongoClientFactory factory;

    private MongoClient mongo;
    public MongoConfig(MongoProperties properties, ObjectProvider<MongoClientOptions> options, Environment environment) {
        super(properties, options, environment);
        this.options = options.getIfAvailable();
        this.factory = new MongoClientFactory(properties, environment);
    }

    @Bean
    @ConditionalOnMissingBean
    public MongoClient mongo() {
        this.options = MongoClientOptions.builder().addClusterListener(new LoggingClusterListener()).addServerListener(new CustomServerListener()).build();
        this.mongo = this.factory.createMongoClient(this.options);
        return this.mongo;
    }
}

2.增加集群监听器

@Component
public class LoggingClusterListener implements ClusterListener {


    @Override
    public void clusterOpening(ClusterOpeningEvent event) {
        System.out.println("clusterOpening");
    }

    @Override
    public void clusterClosed(ClusterClosedEvent event) {
        System.out.println("clusterClosed");
    }

    @Override
    public void clusterDescriptionChanged(ClusterDescriptionChangedEvent event) {
        System.out.println("clusterDescriptionChanged");
    }
}

3.增加server监听器：

@Component
public class LoggingClusterListener implements ClusterListener {


    @Override
    public void clusterOpening(ClusterOpeningEvent event) {
        System.out.println("clusterOpening");
    }

    @Override
    public void clusterClosed(ClusterClosedEvent event) {
        System.out.println("clusterClosed");
    }

    @Override
    public void clusterDescriptionChanged(ClusterDescriptionChangedEvent event) {
      /*  event.getPreviousDescription().getClusterSettings();
        System.out.println("clusterDescriptionChanged");*/
    }
}
