当我尝试部署 Web 项目时，Wildfly 总是返回此错误：

我不知道项目中缺少什么，也不知道该怎么办。在 localhost 我也有一个 keycloak 服务器，但它没有打扰这个，不是吗？

【问题讨论】：

你的 JSF 配置有问题
在 web.xml 中？

标签： html spring maven wildfly web-deployment

【解决方案1】：

如果其他人有这个，但 maven 不是问题，在我的例子中，这个错误是因为我没有 beans.xml（显然，JSF 明确需要一个）。

【讨论】：

【解决方案2】：

添加 beans.xml 可以解决您的问题。

【讨论】：

你能详细说明一下答案吗

【解决方案3】：

终于解决了。我遇到的主要问题是我将其配置为 Maven 项目，而我没有将其编译为 Maven。

【讨论】：

【解决方案4】：

对我来说，它通过在 WEB-INF/ 目录上添加一个“空”beans.xml 来解决。
详情请参阅here。

【解决方案5】：

在 WEB-INF/ 上创建文件 beans.xml 并将此代码添加到其中

<?xml version="1.0"?>
<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_2_0.xsd"
       version="2.0"
       bean-discovery-mode="all">

</beans>
