上传文件 服务端模拟存储

这里可以选用Parcelable来进行序列化，parcelable效率更高，我这里选用的是serializable

服务端和客户端都要有此文件，并且所在的包名要一致

不懂可以参考parcelable(http://www.cnblogs.com/mydomainlistentome/p/4687173.html);

package lyl.sole.util;

import java.io.Serializable;

public class SerializUtil implements Serializable {
	private String title;  
	private byte[] contentData;
	private long contentLength;
	private String ext;
	private String TypeMime;

	
	public String getTitle() {
		return title;
	}
	public void setTitle(String title) {
		this.title = title;
	}
	public byte[] getContentData() {
		return contentData;
	}
	public void setContentData(byte[] contentData) {
		this.contentData = contentData;
	}
	public long getContentLength() {
		return contentLength;
	}
	public void setContentLength(long contentLength) {
		this.contentLength = contentLength;
	}
	public String getExt() {
		return ext;
	}
	public void setExt(String ext) {
		this.ext = ext;
	}
	public String getTypeMime() {
		return TypeMime;
	}
	public void setTypeMime(String typeMime) {
		TypeMime = typeMime;
	}
	
	
}
