问题描述

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，查询应该在 300 毫秒后失败).

I would like to lower the timeout setting in my spring-mongo java application (the query should fail after 300 ms if the database is not accessible).

我试过这个配置:

@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 选项和构建器都会更改超时:查询仅在 30 000 毫秒后失败.

But the mongoUri options nor the builder change the timeout: the query fails only after 30 000ms.

我不确定应该覆盖哪个参数，也不确定如何正确执行.

I am not sure which parameter I should override nor the way to do it properly.

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

@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));
}
