请使用“ MongoMappingContext＃setAutoIndexCreation（boolean）”或覆盖“MongoConfigurationSupport＃autoIndexCreati

在application.properties文件中禁用自动索引创建

spring.data.mongodb.auto-index-creation=false

或application.yml文件

spring:  data:    mongodb:      auto-index-creation: false

创建类MongoConfiguration whit @Configuration批注

Injetc这种依赖

private final MongoTemplate mongoTemplate;private final MongoConverter mongoConverter;

并添加此方法

@EventListener(ApplicationReadyEvent.class)public void initIndicesAfterStartup() {    log.info("Mongo InitIndicesAfterStartup init");    var init = System.currentTimeMillis();    var mappingContext = this.mongoConverter.getMappingContext();    if (mappingContext instanceof MongoMappingContext) {        MongoMappingContext mongoMappingContext = (MongoMappingContext) mappingContext;        for (BasicMongoPersistentEntity<?> persistentEntity : mongoMappingContext.getPersistentEntities()) { var clazz = persistentEntity.getType(); if (clazz.isAnnotationPresent(document.class)) {     var resolver = new MongoPersistentEntityIndexResolver(mongoMappingContext);     var indexOps = mongoTemplate.indexOps(clazz);     resolver.resolveIndexFor(clazz).forEach(indexOps::ensureIndex); }        }    }    log.info("Mongo InitIndicesAfterStartup take: {}", (System.currentTimeMillis() - init));}

记住var仅适用于Java 11+

最后一课，使用龙目岛
