Spring 分派传入RPC调用时发生异常-GWT 2.6

我正在使用“GWTRPCSpring”库与Spring一起处理一个GWT（2.6）项目

我正在尝试将POJO从服务器发送到客户端，我得到了一个Springbean的POJO实例，并且运行良好，但当我尝试将其发送到客户端时，出现了以下异常：

[WARN] Exception while dispatching incoming RPC call
com.google.gwt.user.client.rpc.SerializationException: Type 'java.lang.IllegalArgumentException' 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 = java.lang.IllegalArgumentException: Unable to find public method: setName with 0 params.

我的目标是：

import java.io.Serializable;

import com.google.gwt.user.client.rpc.IsSerializable;

public class ApplicationItem implements Serializable, IsSerializable
{
    private static final long serialVersionUID = 1L;

    private long id;
    private String name;    
    private String path;
    private String grant;
    private String icon;

    public ApplicationItem(){}

    public void setId(long id)
    {
        this.id = id;
    }

    public long getId()
    {
        return id;
    }

    public void setName()
    {

    }

    public void setName(String name)
    {
        this.name = name;
    }

    public String getName()
    {
        return this.name;
    }

    public void setPath(String path)
    {
        this.path = path;
    }

    public String getPath()
    {
        return path;
    }

    public void setGrant(String grant)
    {
        this.grant = grant;
    }

    public String getGrant()
    {
        return grant;
    }

    public void setIcon(String icon)
    {
        this.icon = icon;
    }

    public String getIcon()
    {
        return icon;
    }

    @Override
    public String toString()
    {
        return "ApplicationItem: ["+this.id+", "+this.name+", "+this.path+", "+this.grant+", "+this.icon+"]";
    }
}

非常感谢您的帮助。

在删除额外的无参数

setName（）

方法后，您是否尝试过id？是的，事实上，我添加了该方法来尝试，但如果没有它也无法工作。您是否使用内置Jetty server的eclipse？或者您正在使用与eclipse集成的Tomcat服务器？我在eclipse上默认使用Jetty。
