测试两个方法是否具有相同的名称，即返回类型，参数计数和参数类型。

/**

 * @file AnnotationUtil.java

 * 

 *       AnnotationUtil is a utility to get all annotations of a class, its

 *       methods,

 *       and the method parameters. Returned annotations include all annotations

 *       of

 *       the classes interfaces and super classes.

 *       Requested classes are cached, so requesting a classes annotations

 *       repeatedly

 *       is fast.

 * 

 *       Example usage:

 * 

 *       AnnotatedClass annotatedClass = AnnotationUtil.get(MyClass.class);

 *       List<AnnotatedMethod> methods = annotatedClass.getMethods();

 *       for (AnnotatedMethod method : methods) {

 *       System.out.println("Method: " + method.getName());

 *       List<Annotation> annotations = method.getAnnotations();

 *       for (Annotation annotation : annotations) {

 *       System.out.println("    Annotation: " + annotation.toString());

 *       }

 *       }

 * 

 * @brief

 *        AnnotationUtil is a utility to retrieve merged annotations from a

 *        class

 *        including all its superclasses and interfaces.
