Tomcat default classlLoader is WebappClassLoader, but you need `TomcatInstrumentableClassLoader. There are two solutions: Modify WebappLoader.class Change WebappLoader.java private String loaderClass = “org.apache.catalina.loader.WebappClassLoader”; Replace： private String loaderClass = “org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader”; Compile it and replaced the class file(catalina.jar), then it works. Here is required dependency jars: catalina.jar,tomcat-coyote.jar,tomcat-util.jar(/bin),tomcat-juli.jar Modify context.xml: <?xml version=”1.0″ encoding=”UTF-8″?> <Context> <Loader loaderClass=”org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader”/> </Context>
