我发现了一个相当令人难以置信的 JSF 日期转换库，名为 Pretty Time。我已将 maven 坐标包含在我的 pom.xml 中：

    <dependency>
        <groupId>org.ocpsoft.prettytime</groupId>
        <artifactId>prettytime-integration-jsf</artifactId>
        <version>2.1.3.Final</version>
        <scope>runtime</scope>
    </dependency>

这是我页面的相关部分：

<h:column>
    <f:facet name="header">Last Updated</f:facet>
    <h:outputText value="#{item.lastUpdated}">
        <f:converter converterId="org.ocpsoft.PrettyTimeConverter" />
    </h:outputText>
</h:column>

我正在部署到 TomEE v1.5.1+。我得到了这个例外。我错过了一步吗？我确实注意到该类org.ocpsoft.PrettyTimeConverter没有标有@FacesConverter注释。这会是个问题吗？

编辑：我倾向于 TomEE/MyFaces 错误......或功能。不管你想怎么称呼它：

我的项目的 faces-config 使用 2.1 命名空间：

<faces-config
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_1.xsd"
    version="2.1">

而 prettytime 使用已弃用的：

<faces-config xmlns="http://java.sun.com/xml/ns/javaee"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_1_2.xsd"
   version="1.2">

将转换器添加到我的项目的 faces 配置中会使一切正常工作。

转换器在捆绑的 faces-config.XML 中定义 - https://github.com/ocpsoft/prettytime/blob/master/jsf/src/main/resources/META-INF/faces-config.xml

我会确保您拥有所需的所有依赖项。核心 jar 和 jsf 集成。

您可能在 tomee 中发现了某种错误，但我认为这极不可能。我会试着在几个小时内仔细看看。

您的 JSF 实现抱怨它找不到带有 id 的转换器prettyTimeConverter。但是在您发布的代码中，您正在引用org.ocpsoft.PrettyTimeConverter（这是正确的）。您应该再次检查转换器 ID。我想这只是一个错字。
