显示数据库中image出错
String sql = "select image from t1 WHERE id=4";
String className = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
String url = "jdbc:sqlserver://localhost:1433;databaseName=test1"; // 数据库名字
String user = "sa";
String pswd = "sa";
Class.forName(className);
Connection conn = DriverManager.getConnection(url, user, pswd);
PreparedStatement ps=conn.prepareStatement(sql);
ResultSet rs=ps.executeQuery();
if(rs.next()) {
[b] InputStream in = rs.getBinaryStream(1); ServletOutputStream op = response.getOutputStream();
int len;
byte[] buf=new byte[1024];
while((len= in.read(buf))!=-1) {
op.write(buf, 0, len);
in.read(buf);
}
op.close();
in.close();
}
在InputStream in = rs.getBinaryStream(1)时候出错？？？？？
[解决办法]
楼主把image以流的方式写到数据库？ 存路径就可以了。何必这么麻烦
