Payara MicroProfile 5.191 在清理、编译、打包、运行后中断“找不到转换器”

【问题标题】：Payara MicroProfile 5.191 intermitted "converter not found" after clean, compile, package, runPayara MicroProfile 5.191 在清理、编译、打包、运行后中断“找不到转换器”
【发布时间】：2019-10-07 05:13:24
【问题描述】：

我有一个带有使用转换器的 JSF 页面的 Java EE 8 Web 项目（战争）。

当我尝试加载该页面时（在 mvn clean compile package 和 java -jar payara-micro-5.191.jar --deploy rbooking.war 之后）“有时”找不到转换器类。

要解决这个问题，唯一的办法就是重新编译war。

这里有一些细节：

转换器类：

package sartorieinformatiche.it.rbooking.control;

import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
import javax.faces.convert.FacesConverter;
import javax.inject.Inject;

import sartorieinformatiche.it.rbooking.entity.Language;

@FacesConverter(value = "languageConverter", managed = true)
public class LanguageConverter implements Converter<Language> {

  @Inject
  private LanguageService languageService;

  @Override
  public String getAsString(FacesContext context, UIComponent component, Language language) {
    if (language == null) {
      return "";
    }

    return language.getId().toString();
  }

  @Override
  public Language getAsObject(FacesContext context, UIComponent component, String value) {
    if (value == null || value.trim().isEmpty()) {
      return null;
    }

    Long id = Long.parseLong(value);

    return languageService.findById(id);
  }

}

JSF 页面片段：

...<p:selectOneMenu id="language"
                 value="#{bookingBean.booking.language}"
                 converter="languageConverter">
  <f:selectItems value="#{bookingBean.allLanguages}"
                 itemLabel="#{language.description}"
                 itemValue="#{language.id}" />
    <p:column>
      <h:outputText value="#{language.description}" />
    </p:column>
</p:selectOneMenu>...

JSF页面加载时的错误：

为了解决这个问题，我必须重新编译项目并且转换器已正确加载...

有解决问题的办法吗？

PS： 我正在使用 OpenJDK 运行时环境（构建 1.8.0_212-8u212-b03-0ubuntu1.16.04.1-b03）Linux Mint 18.3 Sylvia。

【问题讨论】：

  • JSF 与编译或创建战争无关，您的服务器和 java-ee-8 也不是很广泛。那么你如何实际创建你的战争并编译东西呢？纯命令行行家？当事情失败时，班级真的不在那里吗？
  • 谢谢 Kukeltje，我刚刚再次测试，应用程序现在运行没有错误，我已经停止它，修改了一个插入评论的类，然后我运行干净并从 IDE（NetBeans 11 在 OpenJDK 运行时环境 11.0.1+13-Ubuntu-3ubuntu116.04ppa1) 上运行，LanguageConverter.class 已插入战争但再次运行我收到：javax.faces.FacesException：表达式错误：命名对象：未找到语言转换器， clean / build / run 再次它工作......我不明白会发生什么......（同样的问题：mvn clean compile package）
  • 检查 payara 是否可以/应该在部署之间进行清理，以防止陈旧的东西挥之不去。检查另一个容器是否有同样的问题（如果你创建了minimal reproducible example，应该不难）
  • 问题似乎出在 payara micro 上，如果我尝试停止并运行服务器 20 次，12 次启动良好，8 次启动错误（未找到语言转换器）（根本没有重新编译）
  • 部署期间检查错误...
