缓存更新策略的列举和比较
在现代软件架构中，缓存是提高系统性能和扩展性的关键组件之一。然而，缓存的有效管理，特别是缓存更新策略，对于保持数据一致性和系统可靠性至关重要。 本文将简单探讨和比较几种常见的缓存更新策略，以及它们各自的优缺点。 Note: 启发自 《从程序员到架构师：大数据量 缓存、高并发、微服务 多团队协同等核心场景实战》一书的第四章：读缓存。

JSON serialization and deserialization: Circular References
In recent times, I did a lot practise of micro-service with spring boot. And handled a lot of JSON(Jackson) related serialization and deserialization issues. In this post, I will share some tricky how to “fix” Circular References.
Quick start: swagger, spring-boot and Jersey
在做服务器端API开发的时候，如何保持文档的更新是一个比较头疼的问题。试过写成word文档，缺点很明显： 更新不及时 不便于查阅 也试过用其他的在线API管理工具，太懒了，总是无法保持更新。而且大多数服务还是收费的。
Tip: Upload Multiple Files with Jersey
这篇文章将简单介绍一下如何用Jersey（DropWizard）在一次Request中接受多个文件。其实Google一下，SO上会有很多回答，只是在这边献丑一下。
