Java 中 Blob类型和String类型相互转换

1、String 转 Blob:

 import org.hibernate.Hibernate;

    String content = "Hello World!";  

    Blob blob = Hibernate.createBlob(content.getBytes());  

2、Blob 转 String:  

Blob blob;  
  
    try{  
         String content = new String(blob.getBytes((long)1, (int)blob.l 
                ength()));  
    } catch(SQLException e) {  
         e.printStackTrace();  
    }
