任何人都可以帮助我理解为什么我的应用程序在运行时抛出这个错误

深入研究我可以看到的代码：

[ERROR] Resource org/jboss/errai/ui/demo/client/local/PasswordRequiredPage.html not found. Is the name specified as Class.getResource() would expect?

但是，html 页面与相应的 PasswordRequiredPage.java 一起存在：

PasswordRequiredPage.java：

@Dependent
@Templated("#passwordrequired")
@Page
public class PasswordRequiredPage extends Composite {
}

PasswordRequiredPage.html：

<div data-field="passwordrequired">
 <!-- Content -->
</div>

我的申请可能出了什么问题？我已经搞定了：

 - mvn clean (SUCCESS)
 - mvn gwt:compile (FAIL)
 - mvn gwt:run (FAILE)

虽然您PasswordRequiredPage.html在同一个文件夹中，PasswordRequiredPage.java但当 gwt 编译器运行时，它应该在类路径中。

您可以通过两种方式修复它：

  1. 复制PasswordRequiredPage.html到java编译器生成的文件夹，PasswordRequiredPage.class完成配置maven-resources-plugin（目标copy-resources）

  2. 将源文件夹添加.html到您的编译类路径中。

我从未使用过 Errai，也不知道它是如何使用 gwt 编译器的，但由于某种原因，它正在将 .java 文件添加到类路径（可能也是 .css 和 .png ）但没有 .html 文件。

也许，您必须将路径添加到@Page注释中；就像它出现在官方指南中一样。

不确定，但据我所知，您应该在 HTML 中使用id属性进行模板化。数据字段用于在相应的 java 代码中注入小部件或构造元素以对其进行处理。

尝试

<div id="passwordrequired">
 <!-- Content -->
</div>

在 java 代码中，“this”将对应于根小部件/复合材料。
