继续此处的较早问题。尝试通过 HTTP 发送此对象 Employee。我没有收到任何错误,但希望在另一端打印出员工详细信息,但没有发生任何事情。我正在打开我的日志文件以查看我的 tomcat 服务器上的打印输出,但除了方法已开始显示 START 打印输出的指示之外,我没有得到 END 打印输出。因此,该部分中的某些内容无法正常工作。
这是测试类Employee:
public class Employee implements java.io.Serializable {
public String name;
public String address;
public transient int SSN;
public int number;
public void mailCheck() {
System.out.println("Mailing a check to " + name + " " + address);
}
}
客户端:
公共类 SerializeAndSend {
public static void main(String args[]){
one.Employee e = new one.Employee();
e.name = "Reyan Ali";
e.address = "Phokka Kuan, Ambehta Peer";
e.SSN = 11122333;
e.number = 101;
sendObject(e);
}
public static Object sendObject(Object obj) {
URLConnection conn = null;
Object reply = null;
try {
// open URL connection
URL url = new URL("///myURL///");
conn = url.openConnection();
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setUseCaches(false);
// send object
ObjectOutputStream objOut = new ObjectOutputStream(conn.getOutputStream());
objOut.writeObject(obj);
objOut.flush();
objOut.close();
} catch (IOException ex) {
ex.printStackTrace();
return null;
}
// recieve reply
try {
ObjectInputStream objIn = new ObjectInputStream(conn.getInputStream());
reply = objIn.readObject();
objIn.close();
} catch (Exception ex) {
// it is ok if we get an exception here
// that means that there is no object being returned
System.out.println("No Object Returned");
if (!(ex instanceof EOFException))
ex.printStackTrace();
System.err.println("*");
}
return reply;
}
}
我认为那是正确的。但我被困在服务器端,我在服务器端也有员工类:
public void doPost(HttpServletRequest req, HttpServletResponse resp) throws IOException {
System.out.println("START");
Object obj;
Employee emp = null;
ObjectInputStream objIn = new ObjectInputStream(req.getInputStream());
try {
obj = objIn.readObject();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
try {
emp = (Employee)objIn.readObject();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
System.out.println("END");
System.out.println(emp.name);
}
任何想法在接收端出了什么问题?
