我正在尝试设置我的spring boot配置以使用我的自定义序列化器和反序列化器。
解串器代码
public class CustomZonedDateTimeDeserializer extends JsonDeserializer<ZonedDateTime> {
@Override
public ZonedDateTime deserialize(JsonParser jsonParser, DeserializationContext context)
throws IOException, JsonProcessingException {
ObjectCodec oc = jsonParser.getCodec();
TextNode node = (TextNode) oc.readTree(jsonParser);
String dateString = node.textValue();
return ZonedDateTime.parse(dateString, CustomZonedDateTimeSerializer.formatter);
}
@Override
public Class<?> handledType() {
return ZonedDateTime.class;
}
}
序列化器代码
public class CustomZonedDateTimeSerializer extends JsonSerializer<ZonedDateTime> {
@Override
public Class<ZonedDateTime> handledType() {
return ZonedDateTime.class;
}
public final static DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ssZ");
@Override
public void serialize(ZonedDateTime date, JsonGenerator generator, SerializerProvider provider)
throws IOException, JsonProcessingException {
final String dateString = date.format(formatter);
generator.writeString(dateString);
}
}
这是我的配置：
@Configuration
public class JacksonConfiguration {
@Autowired
Jackson2ObjectMapperBuilder jacksonBuilder;
@PostConstruct
public void configureJackson() {
final CustomZonedDateTimeSerializer serializer = new CustomZonedDateTimeSerializer();
jacksonBuilder.serializers(serializer);
final CustomZonedDateTimeDeserializer deserializer = new CustomZonedDateTimeDeserializer();
jacksonBuilder.deserializers(deserializer);
}
}
我正在创建一个REST API，所以我在控制器中有这个：
@RequestMapping(value = "date", method = { RequestMethod.GET })
@ApiOperation(value = "", notes = "")
public ResponseWrapper<String> testDATE(
@RequestParam @ApiParam(value = "", required = true) ZonedDateTime date) {
System.out.println(date.toString());
return new ResponseWrapper<String>(date.toString());
}
到目前为止，我已经尝试过：
创建一个自定义模块并将其作为@Bean添加到配置中，将序列化器和反序列化器添加到配置中的jackonBuilder对象中，例如此example中的代码
我是否缺少某些东西或做错了什么？
每次尝试时，都会出现以下错误：
“无法将类型'java.lang.String'的值转换为所需的类型
'java.time.ZonedDateTime';嵌套异常为
org.springframework.core.convert.ConversionFailedException：失败
从类型[java.lang.String]转换为类型
[@ org.springframework.web.bind.annotation.RequestParam
@ io.swagger.annotations.ApiParam java.time.ZonedDateTime]作为值
'2018-07-10T00：00：00 + 0000';嵌套异常为
java.lang.IllegalArgumentException：尝试解析值失败
[2018-07-10T00：00：00 + 0000]“
我每次发送以下值：2018-07-10T00：00：00 + 0000，该值甚至没有到达我有断点的解串器。
最佳答案
将此bean添加到您的配置类中：
@Bean
public Jackson2ObjectMapperBuilder configureObjectMapper() {
Jackson2ObjectMapperBuilder builder = new Jackson2ObjectMapperBuilder();
final CustomZonedDateTimeSerializer serializer = new CustomZonedDateTimeSerializer();
builder.serializers(serializer);
final CustomZonedDateTimeDeserializer deserializer = new CustomZonedDateTimeDeserializer();
builder.deserializers(deserializer);
return builder;
}
