在这边文章中,你将要学到的是在项目中配置主从数据库,并且兼容其他数据库哟。。这些都是博主项目中需要并且比较重要的知识哦~
好了,废话不多说,直接进主题。

public abstract class AbstractMongoConfigure {
private String host, database;
private int port;
public MongoDbFactory mongoDbFactory() throws Exception {
return new SimpleMongoDbFactory(new MongoClient(host, port), database);
}
/*
* Factory method to create the MongoTemplate
*/

return host;
}
public void setHost(String host) {
this.host = host;
