我尝试从服务器反序列化类,但在客户端我得到:
java.lang.ClassNotFoundException: com.server.core.StateFilesStruct
在我的客户端中,具有此包名称的 StateFilesStruct 类在哪里:
com.client.core.StateFilesStruct
这是我的课:
public Object deserialize(byte[] bytes) {
ByteArrayInputStream b = new ByteArrayInputStream(bytes);
ObjectInputStream o = null;
try {
o = new ObjectInputStream(b);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
return o.readObject();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return o;
}
我发送这个的类在服务器中:
package com.server.core;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.Hashtable;
public class StateFilesStruct implements Serializable {
private static final long serialVersionUID = 988633010151085730L;
private Hashtable<String,String> Repository;
public Hashtable<String, String> getRepository() {
return Repository;
}
public void setRepository(Hashtable<String, String> repository) {
Repository = repository;
}
public StateFilesStruct()
{
Repository = new Hashtable<String,String>();
}
}
我在客户端中保留的类与服务器类相同,但包名称不同:
package com.client.core;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.Hashtable;
public class StateFilesStruct implements Serializable {
private static final long serialVersionUID = 988633010151085730L;
private Hashtable<String,String> Repository;
public Hashtable<String, String> getRepository() {
return Repository;
}
public void setRepository(Hashtable<String, String> repository) {
Repository = repository;
}
public StateFilesStruct()
{
Repository = new Hashtable<String,String>();
}
}
我试图解决客户端中的类的方法是:使用 ZeroMQ 从 tcpip 套接字接收
byte[] byteFileStruct = m_pNetworkManager.getSocket().recv(0);
StateFilesStruct stateFilesStruct = (StateFilesStruct)deserialize(byteFileStruct);
得到这个异常,因为你可以看到它从服务器类中寻找:
