Spring MVC Jackson DateFormat

于是，可以这样设置：
@JsonSerialize(using=JsonDateSerializer.class)
public Date getDate() {
    return date;
}
其中   JsonDateSerializer是新编写的类，继承了JsonSerializer
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;

import org.codehaus.jackson.JsonGenerator;
import org.codehaus.jackson.JsonProcessingException;
import org.codehaus.jackson.map.JsonSerializer;
import org.codehaus.jackson.map.SerializerProvider;
import org.springframework.stereotype.Component;

public class JsonDateSerializer extends JsonSerializer<Date>{

    private static final SimpleDateFormat dateFormat = new SimpleDateFormat("MM-dd-yyyy");

    @Override
    public void serialize(Date date, JsonGenerator gen, SerializerProvider provider)
            throws IOException, JsonProcessingException {

        String formattedDate = dateFormat.format(date);

        gen.writeString(formattedDate);
    }

}
