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);     } }
