Spring Mongo查询设置自定义超时

Question

我想降低spring-mongo java应用程序中的超时设置（如果无法访问数据库，则查询将在300 ms后失败）。

我尝试了这个配置：

@Configuration
public class MongoConfiguration {

private String mongoUri = "mongodb://127.0.0.1:27017/myDb?connectTimeoutMS=300&socketTimeoutMS=300&waitQueueTimeoutMS=300&wtimeoutMS=300";

@Bean
public MongoDbFactory mongoDbFactory() throws Exception {
    Builder options = new MongoClientOptions.Builder().socketTimeout(300).connectTimeout(300).maxWaitTime(300);
    return new SimpleMongoDbFactory(new MongoClientURI(mongoUri, options));
}

@Bean
public MongoTemplate mongoTemplate() throws Exception {
    MongoDbFactory mongoDbFactory = mongoDbFactory();
    MongoTemplate mongoTemplate = new MongoTemplate(mongoDbFactory);
    return mongoTemplate;
}

}

但是mongoUri选项或构建器都更改超时：仅在30 000ms之后查询失败。

我不确定应该覆盖哪个参数，也不确定该如何正确执行。

谢谢你的帮助

我在这里找到了答案：https : //scalegrid.io/blog/understanding-mongodb-client-timeout-

@Bean
public MongoDbFactory mongoDbFactory() throws Exception {
    MongoClientOptions.Builder optionsBuilder = MongoClientOptions.builder();
    optionsBuilder.connectTimeout(300);
    optionsBuilder.socketTimeout(300);
    optionsBuilder.serverSelectionTimeout(300);
    return new SimpleMongoDbFactory(new MongoClientURI(mongoUri, optionsBuilder));
}
