Question

我正在尝试使用Apache的SerializationUtils将生产者的对象发送给使用者。问题是当我反序列化时出现以下错误：

这是设备类

package com.homedcs.models;

import java.io.Serializable;

public class Device implements Serializable {

private static final long serialVersionUID = 1L;

private int id, type, slaveAddress, channel, value, power, config, location;

public Device() {

}

public Device(int id, int type, int slaveAddres, int channel, int value, int power, int config, int location) {

    this.id = id;
    this.type = type;

}

public int getId() {
    return id;
}

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

public int getType() {
    return type;
}

public void setType(int type) {
    this.type = type;
}

}

我在互联网上搜索了一些关于classpath的内容。我仍然不知道如何解决这个问题。

我使用apache thrift来制作跨平台对象。你只需制作一个节俭文件，用你想要的语言生成课程，非常有帮助，非常容易！
