struts2: config-browser-plugin 与 convention-plugin 学习

convention-plugin、 config-browser-plugin这二个插件的出现,很大程度改善了这个囧境。 简言之:convention-plugin采用约定大于配置”的思想,只要我们遵守约定,完全可以少写配置甚至不写配置;而config-browser-plugin则用于方便的浏览项目中的所有action及其与 如果跑不起来,检查服务器应用WEB-INFlib下是否有struts2-config-browser-plugin-2.3.16.jar 这个文件二、convention-plugin 使用1 2 org.apache.struts3 struts2-convention-plugin4 2.3.165 pom.xml中加上这个后,可以把struts.xml配置文件给干掉了(或者改个名),部署App,如果启动正常,则表示环境ok。 27 WEB-INFcommonerror.jsp28 29 30 31 33 34 35 36 37 hello-world38 home39 40 41 42 43 44 45 47 48 原因在于convention-plugin

    Struts2框架的基本使用(三)

    二、Convention插件的约定      自Struts2.1以来,引入了Convention插件来实现开发零配置,但是正真做到零配置还是很难的,Convention插件已经在尽力的减少配置操作了。 Struts包下lib中有个jar包,struts2-convention-plugin-2.3.32.jar。这就是Convention插件的jar包,我们将它引入到项目中。 我们可以看到利用Convention插件,几乎零配置,只需要记住几个约定即可。下面看Convention的第三个约定,Action链式约定。 三、Convention插件约定的一些细节      在Convention插件中,提供了大量的配置常量用于配置Convention的一些默认值。? Convention中定义的所有的常量都在Convention的jar包的struts-plugin.xml文件中定义了,我们关注几个重点的,如果日后项目中需要用到一些配置可以返回来查找。

    linux内核启动流程分析 - efi_stub_entry

    这就要说到汇编语言的calling convention了。 那对于x64的linux内核来说,calling convention具体是怎么约定的呢? 或者可以看这个表格,比较不同版本的calling convention(是的,有很多版本):? 看上面介绍calling convention时的第一个截图,当被调用函数要使用rbx时,它必须在返回之前,恢复rbx原来的值,所以rbx一定是不会被修改的。 根据calling convention可知,该地址被放到了rax里。继续看efi_stub_entry。
