Eclipse GWT Java Tomcat-上傳到托管服務器時的序列化策略問題

[英]Eclipse GWT Java Tomcat - Serialisation policy issue when I upload to the hosting server

 原文  2014-11-04 21:58:28  5   2    java/ eclipse/ tomcat/ gwt

問題描述

我已經使用Eclipse（4.3.2）和GWT對應用程序進行了更改，並在可以工作的本地Tomcat上對其進行了測試。 但是，當我將其上傳到托管服務器時（不僅是更改的類，我還進行了完整上傳），當我嘗試使用它（登錄）時，在日志中出現以下錯誤：

我所做的更改是：AccountUpdateView.java，在其中添加了標簽和文本框以顯示“組”（客戶端）AccountAndCubs.java，在其中添加了要在AccountUpdateView.java中顯示的新字段（獲取和設置）（客戶端）MySQLConnection.java，我在其中將新字段添加到了sql調用（服務器端）

在搜索中，我發現了一些與此相關的信息，建議我添加“ static final long serialVersionUID = 1L;”。 到我更改的類（AccountUpdateView.java），但是我仍然收到此錯誤。

我注意到這一行： 

SEVERE: Exception while dispatching incoming RPC call
com.google.gwt.user.client.rpc.SerializationException: Type 'org.AwardTracker.client.ViewData' was not assignable to 'com.google.gwt.user.client.rpc.IsSerializable' and did not have a custom field serializer.For security purposes, this type will not be serialized.: instance = org.AwardTracker.client.ViewData@62066d5c

這表示“ ViewData.java”存在一個問題，該問題我尚未更改，但已經存在： 

package org.AwardTracker.client;

import java.io.Serializable;

public class ViewData implements Serializable {
    private static final long serialVersionUID = 1L;

您的幫助將不勝感激。 另外，我不是很熟練，仍在學習中，所以請耐心並使用簡單的語言。

根據要求添加：

ViewData代碼： 

package org.AwardTracker.client;

import java.io.Serializable;

public class ViewData implements Serializable {
    private static final long serialVersionUID = 1L;

    private String accountId;
    private String accountLevel;
    private String ymId;
    private String awId;
    private String adAwardGroup;
    private String adScoutGroup;

    public ViewData() {
        //just here because GWT wants it.
    }

    public String getaccountId() {
        return accountId;
    }   
    public void setaccountId(String accountId) {
        this.accountId = accountId;
    }

    public String getaccountLevel() {
        return accountLevel;
    }   
    public void setaccountLevel(String accountLevel) {
        this.accountLevel = accountLevel;
    }

    public String getymId() {
        return ymId;
    }   
    public void setymId(String ymId) {
        this.ymId = ymId;
    }

    public String getawId() {
        return awId;
    }   
    public void setawId(String awId) {
        this.awId = awId;
    }

    public String getadAwardGroup() {
        return adAwardGroup;
    }
    public void setadAwardGroup(String adAwardGroup) {
        this.adAwardGroup = adAwardGroup;
    }

    public String getadScoutGroup() {
        return adScoutGroup;
    }
    public void setadScoutGroup(String adScoutGroup) {
        this.adScoutGroup = adScoutGroup;
    }

}

AccountsAndCubs.java代碼（已添加“組”）： 

package org.AwardTracker.client;

import com.google.gwt.user.client.rpc.IsSerializable;
import java.util.Date;

public class AccountAndCubs implements IsSerializable {

    static final long serialVersionUID = 1L;

    @SuppressWarnings("unused")
    private AccountAndCubs() {
        //just here because GWT wants it.
    }
    public AccountAndCubs(String accountId, String emailaddress, String password, String level, String pack,
            Integer enabled, Date archived, String group, String acaId, String cdId, String surname, String firstname) {

        this.firstname = firstname;
    }

    public String getAccountId() {
        return accountId;
    }
    public void setAccountId(String accountId) {

    }

    public String getEmailAddress() {
        return emailaddress;
    }
    public void setEmailAddress(String emailaddress) {
        this.emailaddress = emailaddress;
    }

    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }

    public String getLevel() {
        return level;
    }
    public void setLevel(String level) {
        this.level = level;
    }

    public String getPack() {
        return pack;
    }
    public void setPack(String pack) {
        this.pack = pack;
    }

    public Integer getEnabled() {
        return enabled;
    }
    public void setEnabled(Integer enabled) {
        this.enabled = enabled;
    }

    public Date getArchived() {
        return archived;
    }
    public void setArchived(Date archived) {
        this.archived = archived;
    }

    public String getGroup() {
        return group;
    }
    public void setGroup(String group) {
        this.group = group;
    }

    public String getAcaId() {
        return acaId;
    }
    public void setAcaId(String acaId) {
        this.acaId = acaId;
    }

    public String getCdId() {
        return cdId;
    }
    public void setCdId(String cdId) {
        this.cdId = cdId;
    }

    public String getSurname() {
        return surname;
    }
    public void setSurname(String surname) {
        this.surname = surname;
    }

    public String getFirstName() {
        return firstname;
    }
    public void setFirstName(String firstname) {
        this.firstname = firstname;
    }

}

@ IgorKlimer，@ ChrisHinshaw謝謝您的幫助。

經過一番嘗試和錯誤后，我終於可以解決這個問題了。 萬一您想知道（將來會對您有所幫助），我：

  1. 從主機服務器刪除了ROOT.war（要上傳，我需要壓縮war並將重命名的文件重命名為ROOT.war，當我將其上傳到主機的服務器時，該文件會自動安裝並安裝），然后重新啟動

  2. 重新啟動后，我在服務器上上傳了我的工作文件ROOT.war

  3. 重新啟動服務器

  4. 重新啟動后，我嘗試了該應用程序-同樣的問題

  5. 由於某種原因，我將主機服務器上的某個級別升級到private-cgi-bin並找到了另一個ROOT.war，因此我刪除了它

  6. 然后我回到private-cgi-bin / tomcat並刪除了ROOT.war

  7. 然后我重新啟動服務器

  8. 重新啟動后，我然后上傳了我的ROOT.war

  9. 上傳后，我重新啟動了服務器

  10. 重新啟動后，我進入Tomcat Manager，然后選擇Reload

  11. 然后，我啟動了Chrome並清除了緩存

  12. 然后，我嘗試了該應用程序並使其工作，我檢查了更改，這些更改在那里並可以正常工作，我做了一些測試，並檢查了系統日志-一切正常。

問候，

格林

雖然，我還沒有弄清楚實際的解決方法（不能嘗試使用您的解決方法，因為在測試環境中無法刪除ROOT.war），但是我得到了一些可能對其他人有用的解決方法。

上述問題的主要問題是：

找不到序列化策略文件'/org.AwardTracker.AwardTracker/C7227FD579DD02DA4BB5B3EBAD09AE79.gwt.rpc'； 您是否忘記將其包含在此部署中？

通常，發生這種情況是因為已部署的WAR文件包含應用程序文件夾，並且其中包含rpc文件。 但是，由於tomcat緩存或其他任何問題，它仍在尋找先前部署中使用的舊rpc文件。

因此，解決方法是，備份以前的文件並再次復制到應用程序文件夾。
