java - Convert Image to Base64 using Apache Commons -


i'm using base64encoder of sun micro systems convert image base64 string. problem i'm getting warnings during build don't want

java code..

     public static string encodetostring(bufferedimage image, string type) {     string base64string = null;     bytearrayoutputstream bos = new bytearrayoutputstream();     try {     imageio.write(image, type, bos);     byte[] imagebytes = bos.tobytearray();     base64encoder encoder = new base64encoder();     base64string = encoder.encode(imagebytes);     bos.close();     } catch (ioexception e) {     e.printstacktrace();     }     return base64string;     }

warnings:

  [javac] /users/lucy/dev/workspace/flsv2/src/util/bufferimage.java:53: warning: base64encoder internal proprietary api , may removed in future release    [javac] base64encoder encoder = new base64encoder();    [javac] ^    [javac] /users/lucy/dev/workspace/flsv2/src/util/bufferimage.java:53: warning: base64encoder internal proprietary api , may removed in future release    [javac] base64encoder encoder = new base64encoder();    [javac] ^    [javac] 2 warnings

is there way use apache commons in above method no warnings generated? please help..

please not use internal com.sun.* packages. if on v6 or greater can use datatypeconverter. code below.

string base64string = datatypeconverter.printbase64binary(baos.tobytearray()); byte[] bytearray = datatypeconverter.parsebase64binary(base64string);

or,

you can use: java.util.base64 added in java 1.8

string base64string = new string(base64.getencoder().encode(bytestoencode)); byte[] decordedvalue = base64.getdecoder().decode(base64string);

or, can make method calling procedure in apache commons given below

import org.apache.commons.codec.binary.base64; import org.apache.commons.codec.binary.stringutils;  public string decode(string s) {     return stringutils.newstringutf8(base64.decodebase64(s)); } public string encode(string s) {     return base64.encodebase64string(stringutils.getbytesutf8(s)); }

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
