Wildfly问题或重新渲染复合组件的错误 - NoSuchMethodException io.undertow.servlet.spec.PartImp。<init>（）

标签： jsf wildfly-10 composite-component

我在使用复合组件时遇到问题。当组件需要重新呈现时（因为我有基于用户操作显示/隐藏的面板）我得到了以下错误。 （他希望通过使用默认构造函数创建一个新的实例来恢复一个类，但他无法找到/执行该构造函数，因为它不存在？但我不明白为什么他我想这样做以及它失败的原因......）：

我尝试使用 wlp （websphere liberty profile）运行完全相同的代码，然后工作作为魅力，所以我怀疑在下载时遇到问题！

=＆GT;当我看到implementation of that class时，我找不到类中的默认构造函数（PartImpl代码）所以它的逻辑是他无法创建它，但他为什么要这样做恢复/创建该服务器特定类的实例??

  

** java.lang.InstantiationException：io.undertow.servlet.spec.PartImpl       io.undertow.servlet.spec.PartImpl。（）**

这个类是Wildfly类（我想是Wildfly使用的）

调试时我发现了这段代码：

  • this：StateHolderSaver @ 30209
  • classname：io.undertow.servlet.spec.PartImpl

  • 结果：null（抛出以下异常）

    try {
    toRestoreClass = loadClass(className, this);
}
catch (ClassNotFoundException e) {
    throw new IllegalStateException(e);
}

    if (null != toRestoreClass) { try { result = toRestoreClass.newInstance(); } catch (InstantiationException e) { throw new IllegalStateException(e); }

这是错误：

这是我的组件代码：

<cc:interface componentType="fileComponent">
<cc:attribute name="label" type="java.lang.String"/>
<cc:attribute name="value" type="java.lang.Object"/>
<cc:attribute name="action" method-signature="void listener()"/></cc:interface>

<cc:implementation>
<uc:component id="#{cc.clientId}"
              composite="true">

    <uc:fileUpload id="fileUpload"
                   label="#{cc.attrs.label}"
                   value="#{cc.file}"
                   action="#{cc.uploadFile}"
                   render="#{cc.clientId}"
                   displayed="#{empty cc.fileContainer}"
                   accept="image/png,
                           image/jpeg"/>

    <uc:component id="fileContainer"
                  label="#{cc.attrs.label}"
                  displayed="#{not empty cc.fileContainer}">

            <h:commandLink ajax="true">
                <p:fileDownload value="#{cc.downloadFileContainer}"/>
            </h:commandLink>

        <o:commandScript name="action"
                         actionListener="#{cc.attrs.action}"
                         render=":#{cc.clientId}"
                         execute=":#{cc.clientId}"/>

    </uc:component>

</uc:component>

组件类：

@FacesComponent("fileComponent")
public class FileComponent extends UIInput implements NamingContainer {
@Override
public String getFamily() {
    return UINamingContainer.COMPONENT_FAMILY;
}

@Override
public Object getSubmittedValue() {
    return getFileContainer();
}

public FileContainer createFileContainer() {
    return new FileContainer();
}

public void uploadFile() throws IOException {
    FileContainer fileContainer = createFileContainer(); 



fileContainer.setFileName(FilenameUtils.getName(getFile().getSubmittedFileName()));
    fileContainer.setContent(Utils.toByteArray(getFile().getInputStream()));

    setFileContainer(fileContainer);
}

public void downloadFileContainer() throws IOException {
    Faces.sendFile(getFileContainer().getContent(), getFileContainer().getFileName(), true);
}

public Part getFile() {
    return (Part) getStateHelper().eval("file");
}

public void setFile(Part file) {
    getStateHelper().put("file", file);
}

public FileContainer getFileContainer() {
    return (FileContainer) getStateHelper().eval("filecontainer", getValue());
}

public void setFileContainer(FileContainer fileContainer) {
    getStateHelper().put("filecontainer", fileContainer);
}

}

JSF文件（组件的使用）：

... <mc:fileComponent value="#{bean.fileContainer}" /> ...

支持bean 

@ViewScoped
@Named("bean")
public class Bean implements Serializable {
  private FileContainer fileContainer;
  //getters & setters etc
}

components.taglib.xml：

 ...<tag>
    <tag-name>fileComponent</tag-name>
    <component>
        <resource-id>components/fileComponent.xhtml</resource-id>
    </component>
    <attribute>
        <name>id</name>
    </attribute>
    <attribute>
        <name>label</name>
    </attribute>
    <attribute>
        <name>value</name>
        <required>true</required>
    </attribute>
    <attribute>
        <name>action</name>
    </attribute>
</tag>...
