本文整理了Java中java.lang.Package.getAnnotation()方法的一些代码示例，展示了Package.getAnnotation()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Package.getAnnotation()方法的具体详情如下：
包路径：java.lang.Package
类名称：Package
方法名：getAnnotation

Package.getAnnotation介绍

[英]Returns the annotation associated with the specified annotation type and this package, if present.
[中]返回与指定批注类型和此包（如果存在）关联的批注。

代码示例

/**
 * Indicates whether the specified annotation is present.
 *
 * @param annotationType
 *            the annotation type to look for.
 * @return {@code true} if the annotation is present; {@code false}
 *         otherwise.
 * @see java.lang.reflect.AnnotatedElement#isAnnotationPresent(java.lang.Class)
 */
public boolean isAnnotationPresent(Class<? extends Annotation> annotationType) {
  return getAnnotation(annotationType) != null;
