字符串与blob、clob互转

1、String 转 Blob:


    String a= "Hello World!";


    Blob blob = Hibernate.createBlob(a.getBytes(Charset.forName("utf-8")));


2、Blob 转 String:


    Blob blob;


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