    MyBatis Dynamic SQL

    MyBatis Dynamic SQL

    SQL DSL (Domain Specific Language) for Kotlin and Java

    This library is a general-purpose SQL generator. Think of it as a typesafe and expressive SQL DSL (domain-specific language), with support for rendering SQL formatted properly for MyBatis3 and Spring's NamedParameterJDBCTemplate. The library also contains extensions for Kotlin that enable an idiomatic Kotlin DSL for SQL. The library will generate full DELETE, INSERT, SELECT, and UPDATE statements. The DSL implemented by the library is very similar to native SQL but it includes many functions that allow for very dynamic SQL statements.

    MyBatis Spring Adapter

    MyBatis Spring Adapter

    Spring integration for MyBatis 3

    MyBatis-Spring adapter is an easy-to-use Spring Framework bridge for MyBatis sql mapping framework. MyBatis-Spring integrates MyBatis seamlessly with Spring. This library allows MyBatis to participate in Spring transactions, takes care of building MyBatis mappers and SqlSessions and inject them into other beans, translates MyBatis exceptions into Spring DataAccessExceptions, and finally, it lets you build your application code free of dependencies on MyBatis, Spring or MyBatis-Spring. Spring version 2 only supports iBATIS version 2. An attempt was made to add MyBatis 3 support into Spring 3 (see the Spring Jira issue. Unfortunately, Spring 3 development ended before MyBatis 3 was officially released. Because the Spring team did not want to release with code based on a non-released version of MyBatis, official Spring support would have to wait.

    Netty Learning

    Netty Learning

    Web application framework for Java

    Netty Learning is a Chinese-language learning repository focused on explaining the source code and architecture of the Netty Java networking framework. It is aimed at developers who already use Netty or want to understand how high-performance network applications are built. The material examines Netty's design principles, networking concepts, and major internal structures. Articles cover buffers, Channel pipelines, the Reactor pattern, handlers, and asynchronous behavior. A practical section demonstrates building a SOCKS proxy with Netty. The repository also includes source material related to Netty 3.7 and links to additional learning resources. Its purpose is educational source-code analysis rather than providing a new networking framework.

    Netty demos

    Demos of Netty 4.x User Guide

    Netty Demos is a Java example collection that accompanies the Chinese Netty 4.x User Guide and a related practical book. It lets readers compare standard blocking I/O, NIO, AIO, and Netty implementations of similar network programs. The repository includes echo, discard, time, TCP, UDP, HTTP, HTTP/2, and WebSocket examples. Additional samples explain ByteBuffer, ByteBuf usage modes, thread pools, the Reactor pattern, heartbeat handling, and custom codecs. Serialization demonstrations cover Java objects and JSON through Jackson. Security examples include SSL/TLS mutual authentication, while monitoring modules show a lightweight service and interface. The project uses Netty 4.1.52, Jackson 2.10.1, and JUnit 5.5.2.

    NextBus Public Feed Adapter for Java

    A Java adapter for the NextBus Public XML Feed Service

    Restful Web Service adapter for the NextBus prediction and transit network reporting service. This implementation uses XSD Schema, JAXB and a domain object model to decouple the consuming application from the over-the-wire representation of the data. NextBus is currently providing real-time bus data in several major metro transit agencies including, but not limited to MBTA (Boston), Toronto, Seattle, Brooklyn, Staten Island as well as a number of University towns. In additional to the standalone Adapter, an Enterprise Service Bus pump and demonstration subscription client are available for those interested in Asynchronous integration of the transit feed.
