Connection con = ...
        int[] data = ...
        PreparedStatement stmt= con.prepareStatement("insert into t_test(array_field) values(?)");
        stmt.setObject(1, data,java.sql.Types.BINARY);
        stmt.execute();

正好项目有,就给你一个读取的代码吧.不能完全相同,你自己改一下吧:
Java code

FileOutputStream out = null;
InputStream in = null;
//SQL语句我就不写了,就是select那个字段

try {
if(rs.next()) {
    out = new FileOutputStream("C:\a.jpg");
    in = rs.getBinaryStream("image1");
    byte b[] = new byte[0x7a120];
    for (int i = in.read(b); i != -1;) {
        out.write(b);
      i = in.read(b);
    }
    }
    } catch (Exception e) {
    System.out.println(e);
    }
