java中将String类型的数据转成Blob类型

public static Blob getBlogValue(String strValue,String charsetName){
 Blob blobValue = null;
 try {
 byte[] bytes=strValue.getBytes(charsetName);
 System.out.println("byte[]:"+bytes);
 blobValue=Hibernate.createBlob(bytes);
 } catch (UnsupportedEncodingException e) {
 e.printStackTrace();
 }
 return blobValue;
 }
