UriMatcher not recognizing pattern

阅读更多关于 UriMatcher not recognizing pattern

问题 I'm having trouble with matching URIs in my ContentProvider . It will match paths with one or two "tags" (not sure what the correct term is), for example it can recognize box/# . But as soon as I add a second tag, for example box/#/item , I throw an InvalidArgumentException and my app crashes.

Anyone know what the problem is? I

sleuth+zipkin自定义采样率

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 问题背景 zipkin原生提供的采样率设置，仅能针对全局进行设置，无法做到精细化设置，比如，有些接口我们觉得比较重要，所以想采样率高一点，有些接口很简单，我们希望不采集或者采集率设置低一点，原生是没办法做到的，需要完成这个功能，需要我们重写他的采样率计算器。配置重写下面的是他原生的配置，由于它是使用了@ConditionalOnMissingBean注解的，也就是容器中不存在这个Bean的时候，才初始化他自己默认的配置，因此我们可以重写他的配置。 @Bean @ConditionalOnMissingBean public Sampler defaultTraceSampler(SamplerProperties config) { return new PercentageBasedSampler(config); } 重写配置如下 @Bean Sampler percentageLocalSampler(SamplerLocalProperties samplerLocalProperties){ return new PercentageLocalSampler(samplerLocalProperties); } 1 2 3 4 5 在Config类上面添加

问题 I'm new to the Dancer framework and web apps in general. I have a Dancer project in which I have a route that accepts multiple parameters. So far, no sweat. However, if one of the parameters has a file path as its value then the route is not found. I have tried encoding the parameter string as follows to eliminate the forward slashes: $paramString =~ s/\//%2F/g; and this does encode the slashes as expected (I print it out in the log to make sure). However, after the parameter string is

问题 I want to remove subdomain names from a URI. Example: I want to return 'baseurl.com' from the Uri "subdomain.sub2.baseurl.com".
