Mongodb自动删除过期的数据——TTL索引

使用spring-data-mongodb 2.0.9中的

Document document =  new Document();
document.append("createTime",1);
IndexOptions indexOptions = new IndexOptions();
indexOptions.expireAfter(300L,TimeUnit.SECONDS);
this.mongoTemplate.getCollection("test").createIndex(document,indexOptions);

createTime是时间字段

 

使用spring-data-mongodb 1.7.0中的

BasicDBObject bson = new BasicDBObject();
            bson.append("createTime",1);
BasicDBObject options = new BasicDBObject();
options.append("expireAfterSeconds",7200);
            this.mongoTemplate.getCollection("test").createIndex(bson,options);
