Static encoder codegen with Any #145

nedtwigg · 2018-01-12T07:04:25Z

For jsoniter 0.9.19, with this class:

public class EmailSelf {
	public String subject;
	public String body;
	public Any cidMap;
}

jsoniter codegen generates this:

public class EmailSelf implements com.jsoniter.spi.Encoder {
public void encode(java.lang.Object obj, com.jsoniter.output.JsonStream stream) throws java.io.IOException {
if (obj == null) { stream.writeNull(); return; }
stream.writeRaw("{\"subject\":", 11);
encode_((java2ts.EmailSelf)obj, stream);
stream.write((byte)'}');
}
public static void encode_(java2ts.EmailSelf obj, com.jsoniter.output.JsonStream stream) throws java.io.IOException {
if (obj.subject == null) { stream.writeNull(); } else {
stream.writeVal((java.lang.String)obj.subject);
}
stream.writeRaw(",\"body\":", 8);
if (obj.body == null) { stream.writeNull(); } else {
stream.writeVal((java.lang.String)obj.body);
}
stream.writeRaw(",\"cidMap\":", 10);
if (obj.cidMap == null) { stream.writeNull(); } else {
stream.write((byte)'{', (byte)'}');
jsoniter_codegen.cfg9223372036100299902.encoder.com.jsoniter.any.Any.encode_((com.jsoniter.any.Any)obj.cidMap, stream);

}
}

The problem is if (obj.cidMap == null) { stream.writeNull(); } else { stream.write((byte)'{', (byte)'}');. No matter what value is assigned to cid, it shows up as cid: {} in the generated json. This isn't a problem when the same code is used in dynamic mode.

public class DemoCodegenConfig implements StaticCodegenConfig {

    @Override
    public void setup() {
        // register custom decoder or extensions before codegen
        // so that we doing codegen, we know in which case, we need to callback
        Any.registerEncoders();
        JsonIterator.setMode(DecodingMode.STATIC_MODE);
        JsonStream.setMode(EncodingMode.STATIC_MODE);
        JsonStream.setIndentionStep(2);
        JsoniterSpi.registerPropertyDecoder(User.class, "score", new Decoder.IntDecoder() {
            @Override
            public int decodeInt(JsonIterator iter) throws IOException {
                return Integer.valueOf(iter.readString());
            }
        });
    }

added Any.registerEncoders(); to fix this issue
