Velocity based static website generation under Maven2

For several times I went into the situation where I need to seriously decorate a Maven2 generated website, and a more powerful and scriptable way of writing page content than APT and XDOC is required. CSS can do some decoration work and a customized master velocity layout for maven-site-plugin gives me full control of the template. But still, APT and XDOC are limited as a script language to write content. Velocity content may be ideal.

The idea is rendering Velocity template in a way similar to VelocityLayoutServlet and Apache Turbine, which is merging context with velocity template for content body, then put the body into another layout Velocity template. This work can be done within a maven2 goal easily.

In existing arapaho-maven-plugin project, I created flatsite mojo to do this Velocity based static website generation. It's basically a one class deal so I didn't make it a standalone maven2 plugin. It's not a maven2 report, it's a simplified version of maven-site-plugin replacement.

After flatsite mojo is created, I migrated two existing website subprojects to website project and made them generated by arapaho-maven-plugin:flatsite. These two subprojects are example sites of flatsite.

Spring, Angular and other reasons I like and hate Bazel at the same time

For several weeks I've been trying to put together an Angular application served Java Spring MVC web server in Bazel. I've seen the Java, Angular combination works well in Google, and given the popularity of Java, I want get it to work with open source. How hard can it be to run arguably the best JS framework on a server in probably the most popular server-side language with the mono-repo of planet-scale ? The rest of this post walks through the headaches and nightmares I had to get things to work but if you are just here to look for a working example, github/jiaqi/angular-on-java is all you need. https://github.com/jiaqi/angular-on-java Java web application with Appengine rule Surprisingly there isn't an official way of building Java web application in Bazel, the closest thing is the Appengine rule and Spring MVC seems to work well with it. 3 Java classes, a JSP and an appengine.xml was all I need. At this point, the server starts well but I got "No ...

Customize IdGenerator in JPA, gap between Hibernate and JPA annotations

JPA annotation is like a subset of Hibernate annotation, this means people will find something available in Hibernate missing in JPA. One of the important missing features in JPA is customized ID generator. JPA doesn't provide an approach for developer to plug in their own IdGenerator. For example, if you want the primary key of a table to be BigInteger coming from sequence, JPA will be out of solution. Assume you don't mind the mixture of Hibernate and JPA Annotation and your JPA provider is Hibernate, which is mostly the case, a solution before JPA starts introducing new Annotation is, to replace JPA @SequenceGenerator with Hibernate @GenericGenerator. Now, let the code talk. /** * Ordinary JPA sequence. * If the Long is changed into BigInteger, * there will be runtime error complaining about the type of primary key */ @Id @Column(name = "id", precision = 12) @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "XyzIdGenerator") @SequenceGe...

Project Euler problem 220 - Heighway Dragon

This document goes through a Java solution for Project Euler problem 220 . If you want to achieve the pleasure of solving the unfamiliarity and you don't have a solution yet, PLEASE STOP READING UNTIL YOU FIND A SOLUTION. Problem 220 is to tell the coordinate after a given large number of steps in a Dragon Curve . The first thing came to my mind, is to DFS traverse a 50 level tree by 10^12 steps, during which it keeps track of a direction and a coordinate. Roughly estimate, this solution takes a 50 level recursion, which isn't horrible, and 10^12 switch/case calls. Written by a lazy and irresponsible Java engineer, this solution vaguely looks like: Traveler traveler = new Traveler(new Coordinate(0, 0), Direction.UP); void main() { try { traverse("Fa", 0); } catch (TerminationSignal signal) { print signal; } } void traverse(String plan, int level) { foreach(char c:plan) { switch(c) { case 'F': traveler.stepForward(); break; ca...
