javassist:nested exception is javassist.NotFoundException

https://www.cnblogs.com/xuewen1999/articles/14086285.html

javassist可以用于反射获取方法参数名称,项目中用到,测试用例通过,当发布到tomcat时报错javassist.NotFoundException: xxx.xxx.xxxServicejavassist官网对此有如下说明:

The default ClassPool returned by a static method ClassPool.getDefault() searches the same path that the underlying JVM (Java virtual machine) has. If a program is running on a web application server such as JBoss and Tomcat, the ClassPoolobject may not be able to find user classes since such a web application server uses multiple class loaders as well as the system class loader. In that case, an additional class path must be registered to the ClassPool.

解决此异常的方法:解决此异常的方法:1.(推荐)

ClassPool pool = ClassPool.getDefault();
   ClassClassPath classPath = new ClassClassPath(this.getClass());
   pool.insertClassPath(classPath);


ClassPool pool = ClassPool.getDefault();
pool.appendClassPath("E:\\xxx\\xxx\\target\\xxx_war\\WEB-INF\\lib\\xxx_jar-0.0.1-SNAPSHOT.jar");
