java反射之获取所有方法及其注解（包括实现的接口上的注解），获取各种标识符备忘

    /**
     * 获取类或接口上的所有方法及方法上的注解（包括方法实现上的注解以及接口上的注解），最完整的工具类，没有现成的工具类
     * 
     * @param clz
     * @param clzFilter
     *            仅返回具有指定类注解的类或接口中的方法，默认不过滤
     * @param methodFilter
     *            仅返回具有指定方法注解的方法，默认不过滤。 一般使用类或方法即可，没有必要同时两者
     * @param includeObject
     *            是否包括Object上定义的方法，默认false
     * @param println
     *            是否打印，默认不打印
     * @return
