springboot jackson自定义序列化和反序列化实例

@JsonComponent   //此注释会自动将 Serialize和Deserializer注册到jackson之中。
public class CustomeJackSon {
    public static class Serialize extends JsonSerializer<Date>{
        @Override
        public void serialize(Date date, JsonGenerator jsonGenerator, SerializerProvider serializerProvider) throws IOException {
            SimpleDateFormat _format = new SimpleDateFormat("yyyy-mm--dd");
            String _dateStr =  _format.format(date);
            jsonGenerator.writeString(_dateStr);
        }
    } 
}

@JsonSerialize(using = CustomeJackSon.Serialize.class)
    private Date date;

User home(User id){
        applicationArguments.getOptionNames();
        User _user = new User();
        _user.setId(1);
        _user.setName("张三丰");
        _user.setDate(new Date());
        return _user;
        //return new Date();
    }

@JsonComponent   //此注释会自动将 Serialize和Deserializer注册到jackson之中。
public class CustomeJackSon {
    public static class Deserializer extends JsonDeserializer<Date>{
 
        @Override
        public Date deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException, JsonProcessingException {
            String _name = jsonParser.getCurrentName();
            long _ss = jsonParser.getLongValue();
            return null;
        }
    }
}

@JsonDeserialize(using = CustomeJackSon.Deserializer.class)
    private Date date;
最后在controller参数要使用@RequestBody
@RequestMapping(value = "getValue")
    public String getValue(@RequestBody User user){
        return  "0000000";
    }

@SpringBootConfiguration
public class WebConfig extends WebMvcConfigurationSupport {
    /**
     * 自定义序列化器
     */
    @Override
    protected void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        final MappingJackson2HttpMessageConverter jackson2HttpMessageConverter = new MappingJackson2HttpMessageConverter();
        // Long->String
        final ToStringSerializer toStringSerializer = new ToStringSerializer(Long.class);
        // date-> pattern format
        final DateSerializer dateSerializer = new DateSerializer(false, new SimpleDateFormat("yyyy-MM-dd hh:mm:ss"));
        SimpleModule simpleModule = new SimpleModule();
        simpleModule.addSerializer(toStringSerializer);
        simpleModule.addSerializer(dateSerializer);
        jackson2HttpMessageConverter.getObjectMapper().registerModule(simpleModule);
        converters.add(jackson2HttpMessageConverter);
        super.configureMessageConverters(converters);
    }
}
