Objector 0.2.4 Release in github

Thu, 21 May 2020 00:00:00 +0000

Objector

Objector 是一个简单的对象创建器。

主要支持普通的Pojo对象通过@annotation方式进行字节码增强，将对象直接持久化的微型框架。

目前采用阿里云的表格存储实现，详情见 https://www.aliyun.com/product/ots 待此版本稳定后，将提供其他实现方式如MongoDB

安装方式Install for Maven

来自maven中心库，加入以下依赖。

<dependency>
		<groupId>org.chenmin.open</groupId>
		<artifactId>objector-ots</artifactId>
		<version>0.2.4.1</version>
</dependency>

使用方式Useage

阿里云配置Config for Aliyun.com OpenTableStore

请再classpath中加入配置文件根目录objector.properties

objector.properties in classpath

Welcome to Jekyll!

Sat, 04 Jun 2016 13:50:39 +0000

You’ll find this post in your _posts directory. Go ahead and edit it and re-build the site to see your changes. You can rebuild the site in many different ways, but the most common way is to run jekyll serve, which launches a web server and auto-regenerates your site when a file is updated.

To add new posts, simply add a file in the _posts directory that follows the convention YYYY-MM-DD-name-of-post.ext and includes the necessary front matter. Take a look at the source for this post to get an idea about how it works.

Jekyll also offers powerful support for code snippets:

def print_hi(name)
  puts "Hi, #{name}"
end
print_hi('Tom')
#=> prints 'Hi, Tom' to STDOUT.

Check out the Jekyll docs for more info on how to get the most out of Jekyll. File all bugs/feature requests at Jekyll’s GitHub repo. If you have questions, you can ask them on Jekyll’s dedicated Help repository.

Test Page

Thu, 04 Jun 2015 13:50:39 +0000

This is a test blog page where we can explore how to embedd images in the blog.

Image example 1

Here, I will embedd image from local assets which goes into assets directory in project’s root directory. Choose a specific image, related to particular post. I chose to name the image test-page-image-1.jpg, which I will embedd as:

![my alternate text](/assets/test-page-image-1.jpg);

;

Ofcourse, you can load images from web as well. Just point to image direct URL. For ex, here is one placeholder image:

![my alternate text](http://lorempixel.com/400/200);

;

One cool thing about this is the fact that images adapt themselves to the screen size of device. Try to resize your browser window and check for yourself, Have fun.
