As content management applications become more popular, the need for public, standard content warehouse APIs is becoming increasingly apparent. The goal of the Content Repository for Java™technology API (JSR-170) is to provide such an interface. In this article, I will implement the Apache Jackrabbit with open source JSR-170, design a simple backend similar to the Viking Encyclopedia, and study the features

Sina Weibo data mining recently, need to call the Sina Weibo API, which requires the incoming user ID, that is, UID, for the int64 type. source_id False Int64 The UID of the source user. And there is no int64 type in Java, it's natural to start with long, because the range is not enough with Int. Long uid = 2479449007l; or long uid = 2479449007; Invokes the UID as a paramet

Writing these things is essentially a record of work contact Storm after the learning progress, since it is work, of course, to knock code, so this article on the sharing of basic Java-api bar. First look at the diagram below (no excuse to paint), this is the Storm API use of the most basic interface and abstract class relationship. OK, here we can see clearly

Kafka officially provided two scripts to manage the topic, including additions and deletions to topic. Where kafka-topics.sh is responsible for the creation and deletion of topic, kafka-configs.sh script is responsible for topic modification and query, but many users are more inclined to use the program API to operate topic.

Just as a Connection object creates statement and PreparedStatement objects, it also creates CallableStatement objects that will be used to execute calls to the database stored procedures. To create a CallableStatement object:assume that you need to perform the following Oracle stored procedures: CREATE OR REPLACE PROCEDURE getempname (emp_id in number, emp_first out VARCHAR) as BEGIN SELECT P_first from Employees WHERE ID = emp_id;
