java - Eclipse GWT Java Tomcat - 上传到托管服务器时出现序列化策略问题

Question

我已经使用 Eclipse (4.3.2) 和 GWT 对我的应用程序进行了更改，并在我的本地 Tomcat 上对其进行了测试。但是，当我将它上传到托管服务器时(我进行了完整上传，而不仅仅是我更改的类)，当我尝试使用它(登录)时，我在日志中收到以下错误:

0    [catalina-exec-12] INFO  gwtupload.server.UploadServlet  - UPLOAD-SERVLET init: maxSize=3145728, slowUploads=0, isAppEngine=false, corsRegex=^$
2    [catalina-exec-12] INFO  gwtupload.server.UploadServlet  - UPLOAD-ACTION init: removeSessionFiles=false, removeData=false

我所做的更改是: AccountUpdateView.java 我在其中添加了一个 Label 和一个 TextBox 来显示“Group”(客户端) AccountAndCubs.java 我在其中添加了要在 AccountUpdateView.java(客户端)中显示的新字段(获取和设置) MySQLConnection.java，我在其中将新字段添加到 sql 调用(服务器端)

在我的搜索中，我发现了一些与此相关的信息，建议我添加“static final long serialVersionUID = 1L;”到我更改的类 (AccountUpdateView.java)，但我仍然收到此错误。

我注意到这一行:

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

这表明“ViewData.java”存在问题，我没有更改并且已经存在:

package org.AwardTracker.client;

import java.io.Serializable;

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

非常感谢您对此的帮助。另外，我不是很懂技术，还在学习中，所以请耐心等待我并使用简单的语言。

按要求添加:

查看数据代码:

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 代码(添加了“group”):

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.accountId = accountId;

        this.firstname = firstname;
    }

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

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

}

Answer 1

@IgorKlimer，@ChrisHinshaw 感谢您的帮助。

经过反复试验，我终于可以使用它了。以防万一你想知道(它会在未来帮助你)我:

1. 从主机的服务器删除了 ROOT.war(要上传，我需要压缩 war 并将压缩文件重命名为 ROOT.war，当我将它上传到主机的服务器时，它会自动拾取并安装)并重新启动

2. 重新启动后，我上传了我的工作(在我的服务器上)ROOT.war

3. 重启服务器

4. 重新启动后，我尝试了该应用程序 - 同样的问题

5. 出于某种原因，我在主机服务器上升级到 private-cgi-bin 并发现了另一个 ROOT.war，所以我将其删除

6. 然后我回到 private-cgi-bin/tomcat 并删除了 ROOT.war

7. 然后我重新启动了服务器

8. 重新启动后，我就上传了我的 ROOT.war

9. 上传后我重启了服务器

10. 重新启动后，我进入 Tomcat 管理器并选择重新加载

11. 然后我启动了 Chrome 并清除了缓存

12. 然后我尝试了该应用程序并且它工作了，我检查了我的更改并且它们在那里并且工作，我做了更多的睾丸并检查了系统日志 - 一切正常。

问候，

格林
