本文整理了Java中javax.enterprise.inject.spi.Interceptor类的一些代码示例，展示了Interceptor类的具体用法。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。Interceptor类的具体详情如下：
包路径：javax.enterprise.inject.spi.Interceptor
类名称：Interceptor

Interceptor介绍

[英]Represents an enabled javax.interceptor.

Since CDI 2.0, an implementation of this interface may implement Prioritized in order to enable the interceptor with given priority value for entire application.
[中]表示已启用的javax。拦截器。
自CDI 2.0以来，此接口的实现可能会实现优先级，以便为整个应用程序启用具有给定优先级值的拦截器。

代码示例

private void addInterceptorInstance(Interceptor<Object> interceptor, BeanManagerImpl beanManager, Map<String, SerializableContextualInstance<Interceptor<Object>, Object>> instances, final CreationalContext<Object> creationalContext) {
  Object instance = beanManager.getReference(interceptor, interceptor.getBeanClass(), creationalContext, true);
  SerializableContextualInstance<Interceptor<Object>, Object> serializableContextualInstance
      = beanManager.getServices().get(ContextualStore.class).<Interceptor<Object>, Object>getSerializableContextualInstance(interceptor, instance, creationalContext);
  instances.put(interceptor.getBeanClass().getName(), serializableContextualInstance);
