[心得体会]springmvc在requestbody注解下使用jackson转化日期格式

使用WebMvcConfigurer的方法将converter注入到项目中

@Configuration
public class ConverterConfig implements WebMvcConfigurer {
   
   @Bean
   public ViewResolver viewResolver() {
      InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
      viewResolver.setPrefix("/WEB-INF/pages/");
      viewResolver.setSuffix(".jsp");
      return viewResolver;
   }
   
   @Override
   public void addResourceHandlers(ResourceHandlerRegistry registry) {
      registry.addResourceHandler("/js/**", "/images/**", "/css/**").addResourceLocations("/js/", "/images/", "/css/").resourceChain(true).addResolver(new VersionResourceResolver().addContentVersionStrategy("/**"));
   }
   
   /**
    * jackson的json转化date的converter接口
    *
    * @return
    */
   // @Bean
   public MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter() {
      MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter = new MappingJackson2HttpMessageConverter();
      Jackson2ObjectMapperBuilder jackson2ObjectMapperBuilder = new Jackson2ObjectMapperBuilder();
      ObjectMapper objectMapper = jackson2ObjectMapperBuilder.build();
      objectMapper.enable(SerializationFeature.INDENT_OUTPUT);
      objectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
      DateFormat dateFormat = objectMapper.getDateFormat();
      objectMapper.setDateFormat(new MyDateFormat(dateFormat));
      mappingJackson2HttpMessageConverter.setObjectMapper(objectMapper);
      List<MediaType> list = new ArrayList<>();
      list.add(MediaType.APPLICATION_JSON);
      mappingJackson2HttpMessageConverter.setSupportedMediaTypes(list);
      return mappingJackson2HttpMessageConverter;
   }
   
   /**
    * 增加到我们配置内部
    *
    * @param converters
    */
   @Override
   public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
      converters.add(mappingJackson2HttpMessageConverter());
   }
   
}
