Today, it can be regarded as just the basic completion of its first commercial project, in the development process, style, however with the accumulation of work experience. Finally beginning to understand the importance of abstract thought in object-oriented programming, this article briefly introduces a little bit of my harvest.First of all, the afinal framework is mostly used in today's projects, and the framework is indeed quite good, saving a lot of effort. In the process of writing activiti

Open the Image Selection window an
