Java Blob类型和String类型相互转换

1、String 转 Blob:    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.length()));    } catch(SQLException e) {         e.printStackTrace();    }
