### Question:
PropertiesModulePluginLoader extends AbstractModulePluginLoader { @Override public void loadModulePlugin() throws DriverNotExistException { try { StopWatch stopWatch = StopWatch.getStopWatch("加载模块驱动插件类", false); stopWatch.start("加载模块插件类properties配置。。。"); loadPropertiesJar(); stopWatch.stop(); stopWatch.start("模块插件jar包进行排序。。。"); Collection<JarURLConnection> sortUrls = sorted(); Map<Object, Integer> driverMap = loadProperties(sortUrls); String[] drivers = sortProperties(driverMap); stopWatch.stop(); stopWatch.start("开始加载模块驱动插件类。。。"); loadModulePlugin(drivers); stopWatch.stop(); } catch (IOException e) { log.error(e.getMessage(), e); } } PropertiesModulePluginLoader();  PropertiesModulePluginLoader(String modulePluginProperties); void setDefaultSorted(boolean defaultSorted); void setModulePluginProperties(String modulePluginProperties); @Override void loadModulePlugin();  }### Answer:
@Test public void testLoadModulePlugin() { new PropertiesModulePluginLoader().loadModulePlugin(); }
