oracle ibatis Spring blob

最近用到blob类型的字段，在网上看了看，大部分都没成功。自己试验些时间，整理个可以运行的，以便将来用的时候不用在到网上搜来搜去的了！

闲话少说，只将关键代码贴出来
1.表

create table TBL_SYS_BULLIT  (
   TPI_ID               VARCHAR2(10)                    not null,    
   TPI_TITLE            VARCHAR2(200)                   not null,
   TPI_CONTENT_URL      BLOB )

2.实体BulletinVo.java

public class BulletinVo {

	private String tpiId;
	private String tpiTitle;
	private byte[] tpiContentUrl;

	public BulletinVo() {

	}

	public String getTpiId() {
		return tpiId;
	}

	public void setTpiId(String tpiId) {
		this.tpiId = tpiId;
	}

	public String getTpiTitle() {
		return tpiTitle;
	}

	public void setTpiTitle(String tpiTitle) {
		this.tpiTitle = tpiTitle;
	}

	public byte[] getTpiContentUrl() {
		return tpiContentUrl;
	}

	public void setTpiContentUrl(byte[] tpiContentUrl) {
		this.tpiContentUrl = tpiContentUrl;
	}

}
