【问题描述】：

我正在用 Java 开发一个 REST 应用程序，在 WildFly 8 中运行 WebService 时，我总是出现这个错误，我已经尝试搜索互联网但没有成功。

错误：WELD-000071：托管 bean 类 org.apache.cxf.jaxrs.provider.SourceProvider 必须是 @Dependent

【问题讨论】：

您将应用配置为使用 Spring 作为 DI 框架，但 WELD 也在尝试进行依赖注入？
我认为您遇到了与此处相同的问题：stackoverflow.com/a/34418949/424903。也许我的回答（链接在这里）也能解决这个问题。或者，升级到更现代的 Wildfly 版本也可能会使其消失。但您可能仍在使用 Wildfly 8 是有原因的（不在升级预算之内）。

【解决方案1】：

您能否确保您的应用程序中的 beans.xml 文件具有以下内容：

<?xml version="1.0" encoding="UTF-8"?>  
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"  
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
      xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"  
      bean-discovery-mode="annotated">  
</beans>

检查 bean-discovery-mode 属性。其他可能的值为“无”和“全部”。
