春季 mongo 查询设置自定义超时

Question

我想降低我的 spring-mongo java 应用程序中的超时设置（如果数据库不可访问，查询应在 300 毫秒后失败）。

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 选项和构建器都会更改超时：查询仅在 30 000 毫秒后失败。

我

不确定我应该覆盖哪个参数，也不确定正确覆盖它的方法。

感谢您的帮助

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));
}
