Class OTLSpringBootConfig

java.lang.Object

io.opns.otl.spboot.OTLSpringBootConfig

@Configuration
 @ServletComponentScan(basePackages="io.opns.otl.web.filter")
 @Import(value=io.opns.otl.spring.client.SpringWebConfig.class)
public class OTLSpringBootConfig
extends Object

OTL Spring Boot configuration. Although the TracingWebFilter includes the WebFilter annotation, and today most of the web server/application server can recognize this annotation and accordingly load the filter. However, spring boot uses the embedded web server (Apache Tomcat). Due to the fact that embedded containers do not support WebServlet, WebFilter and WebListener annotations, Spring Boot, relying greatly on embedded containers, introduced this new annotation @ServletComponentScan to support some dependent jars that use these 3 annotations. Here we use the ServletComponentScan annotation as a hint to the embedded web container to facilitate the loading of the OTL filter. This annotation will scan the specified package to find and load the OTL filter. It will be initialized with default configuration, which includes the default FilterSpanDecorator and no skip pattern. The url pattern will be set by spring boot, which is [/*], which means this filter will be invoked for all possible urls.
