createExtension 方法的逻辑稍复杂一下,包含了如下的步骤: 1.通过 getExtensionClasses 获取所有的拓展类 2.通过反射创建拓展对象 3.向拓展对象中注入依赖 4.将拓展对象包裹在相应的 Wrapper 对象中 步骤1是加载拓展类的关键,步骤3,4是dubbo 的 ioc 和 aop的表现 下面我们来重点分析getExtensionClasses 方法的逻辑,...
1. Java SPI的实现 首先定义一个服务接口和两个自定义实现类(一般实现类会由第三方提供): 代码语言:javascript 代码运行次数:0 复制 Cloud Studio代码运行 publicinterfaceSPI{voidsayHello(String s);}publicclassSPIImpl1implementsSPI{@OverridepublicvoidsayHello(String s){System.out.println("Hello, "+s+"!

transfer_one:传输一个spi_transfer,0:传输完成,1:传输进行中,传输完成需要调用spi_finalize_current_transfer函数;这个函数一般由SoC厂家的SPI控制器驱动程序提供; cs_gpio:片选GPIO编号数组,如果一个SPI控制器外接了多个SPI从设备,这里存放的就是每个从设备的片选引脚GPIO编号; ...
The boreholes were drilled by a predator, or possibly a parasite, which selected individuals greater than 2.5 mm long. Crurithyris sp. may have represented an attractive (in terms of energy cost) and easy target for a small-sized predator because of its thin shell and ornament of minute ...
