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

Bean介绍

[英]Represents an javax.enterprise.inject. This interface defines everything the container needs to manage instances of the bean.
[中]表示一个javax。企业注射这个接口定义了容器管理bean实例所需的一切。

    T reference = (T) beanManager.getReference(bean, contractOrImpl, ctx);
    int rank = 1;
    if (bean instanceof JerseyBean) {
      rank = ((JerseyBean) bean).getRank();
    }
