convention

从 struts2.1 开始， struts2 不再推荐使用 Codebehind 作为零配置插件，而是改为使用 Convention 插件来支持零配置，和 Codebehind 相比， Convention 插件更彻底，该插件完全抛弃配置信息，不仅不需要是使用 struts.xml 文件进行配置，甚至不需要使用 Annotation 进行配置，而是由 struts2 根据约定自动配置。 如何使用 Convention 1. 将 struts-Convention-plugin-2.1.6.jar 文件复制到 WEB-INF/lib 路径下 2. 对于 Convention 插件而言，它会自动搜索位于 action ， actions ， struts ， struts2 包下的所有 java 类， Convention 插件会把如下两种 java 类当成 Action 处理： 1） 所有实现了 com.opensymphony.xwork2.Action 的 java 类 2） 所有类名以 Action 结尾的 java 类 3. Convention 插件还允许设置如下三个常量： 1） struts.Convention.exclude.packges: 指定不扫描哪些包下的 java 类，位于这些包结构下的 java 类将不会自动映射成 Action ； 2） struts

Here's my database structure: In my app I have a company management of customers, employees and branches. Customers and Employees are associated with one Person, one Individual and one User. Branches are associated with one Person and one Company. So, to

Is there a convention for naming tables when using Doctrine ORM? I like to name tables with the plural but if there's a convention I want to stick to it. So the table 'users' would be related to tables using the fk as the singular ('user_id'). Is there a best practice for this (using singular or plural table names) and if the latter, how does this apply to tables where the plural isn't a simple case of adding an 's'. For example I currently have a table called 'categorys' instead of 'categories' to maintain the convention of adding 's'. Is this a sensible approach? I used to use plural table

No matter which C-compatible library I use, when I look at the header defined constants, they are always defined as hexadecimal values. Here, for instance, in GL/gl.h: #define GL_POINTS 0x0000 #define GL_LINES 0x0001 #define GL_LINE_LOOP 0x0002 #define GL_LINE_STRIP 0x0003 #define GL_TRIANGLES 0x0004 #define GL_TRIANGLE_STRIP 0x0005 #define GL_TRIANGLE_FAN 0x0006 #define GL_QUADS 0x0007 #define GL_QUAD_STRIP 0x0008 #define GL_POLYGON 0x0009 Is there any particular reason for this convention, why not simply use decimal values instead? There are a number of possible reasons: 1) Bit flags are

For example, I've always seen methods referred to as String#split , but never String.split , which seems slightly more logical. Or maybe even String::split , because you could consider #split to be in the namespace of String . I've even seen the method alone, when the class is assumed/implied ( #split ). I understand that this is the way methods are identified in ri. Which came first? Is this to differentiate, for example, methods from fields? I've also heard that this helps differentiates instance methods from class methods. But where did this start? The difference indicates how you access
