java mongodb and_Java中mongodb使用and和or的复合查询

条件类似：a=5 or (a=2 and b>3)

BasicDBList endList = new BasicDBList();

BasicDBObject forceEnd = new BasicDBObject();

forceEnd.put("status", 5);

BasicDBList condList = new BasicDBList();

BasicDBObject autoEnd = new BasicDBObject();

condList.add(new BasicDBObject("status", 2));

condList.add(new BasicDBObject("endTime", new BasicDBObject("$lt", new Date())));

autoEnd.put("$and",condList);

endList.add(forceEnd);

endList.add(autoEnd);

basicDBObject.put("$or",endList);
