Spring @ResponseBody Jackson JsonSerializer 与 JodaTime [英] Spring @ResponseBody Jackson JsonSerializer with JodaTime

问题描述

我有以下用于 JodaTime 处理的序列化程序:

I have below Serializer for JodaTime handling:

public class JodaDateTimeJsonSerializer extends JsonSerializer<DateTime> {

    private static final String dateFormat = ("MM/dd/yyyy");

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

        String formattedDate = DateTimeFormat.forPattern(dateFormat).print(date);

        gen.writeString(formattedDate);
    }

}

然后，在每个模型对象上，我这样做:

Then, on each model objects, I do this:

@JsonSerialize(using=JodaDateTimeJsonSerializer.class )
public DateTime getEffectiveDate() {
    return effectiveDate;
}

通过上述设置，@ResponseBody 和 Jackson Mapper 肯定可以工作.但是，我不喜欢我一直在编写 @JsonSerialize 的想法.我需要的是在模型对象上没有 @JsonSerialize 的解决方案.是否可以将这个配置写在 spring xml 中的某处作为一个配置?

With above settings, @ResponseBody and Jackson Mapper sure works. However, I don't like the idea where I keep writing @JsonSerialize. What I need is a solution without the @JsonSerialize on model objects. Is it possible to write this configuration somewhere in spring xml as a one configuration?

感谢您的帮助.

推荐答案

虽然您可以为每个日期字段添加注释，但最好为您的对象映射器进行全局配置.如果您使用 jackson，您可以按如下方式配置您的弹簧:

Although you can put an annotation for each date field, is better to do a global configuration for your object mapper. If you use jackson you can configure your spring as follow:

<bean id="jacksonObjectMapper" class="com.company.CustomObjectMapper" />

<bean id="jacksonSerializationConfig" class="org.codehaus.jackson.map.SerializationConfig"
    factory-bean="jacksonObjectMapper" factory-method="getSerializationConfig" >
</bean>

对于 CustomObjectMapper:

For CustomObjectMapper:

public class CustomObjectMapper extends ObjectMapper {

    public CustomObjectMapper() {
        super();
        configure(Feature.WRITE_DATES_AS_TIMESTAMPS, false);
        setDateFormat(new SimpleDateFormat("EEE MMM dd yyyy HH:mm:ss 'GMT'ZZZ (z)"));
    }
}

当然，SimpleDateFormat 可以使用您需要的任何格式.

Of course, SimpleDateFormat can use any format you need.
