Question

我正在尝试使用Mongo DB建立一个Spring Boot 2项目，但我面临的问题是，即使我已配置为使用外部mongo，它仍在不断旋转嵌入式mongo DB

配置

@EnableReactiveMongoRepositories
public class MongoReactiveApplication  {

    @Value("${spring.data.mongodb.uri}")
    private String mongoUri;

    @Bean
    public MongoClient mongoClient() {
        return MongoClients.create(mongoUri);
    }

}

yaml spring.data.mongodb.uri: mongodb://localhost:27017/mongotest

如何更改配置以使用外部mongo？

Answer 1

添加这些bean有助于我连接到外部mongo

@Value("${spring.data.mongodb.uri}")
private String mongoUri;

@Bean
public MongoClient mongoClient() {
    return MongoClients.create(mongoUri);
}

@Bean
public ReactiveMongoTemplate reactiveMongoTemplate() {
    return new ReactiveMongoTemplate(reactiveMongoDatabaseFactory());
}

@Bean
public ReactiveMongoDatabaseFactory reactiveMongoDatabaseFactory() {
    return new SimpleReactiveMongoDatabaseFactory(mongoClient(), "mongotest");
}

Answer 2

尝试一下

var mongoose = require('mongoose');
var itemSchema = new mongoose.Schema({ name: {type: String, required: true}});
module.exports = mongoose.model('W8DBItem', itemSchema);

Spring Boot 2配置反应式Mongo数据库存储库而无需EmbeddedMongo
