使用不同的jackson ObjectMappers进行分离RequestMapping

Question

我有一个@requestmapping使用自定义MIME类型。该请求使用@configuration中定义的ObjectMapperbean来启用JSONPARSER.feature.allow_backslash_escaping_any_character。

是否有一种方法可以区分用于每个@controller或@requestmapping的ObjectMapper？

对象映射器Bean

@Bean
public ObjectMapper objectMapper() {
    Jackson2ObjectMapperBuilder builder = new Jackson2ObjectMapperBuilder();
    builder.featuresToEnable(
      JsonParser.Feature.ALLOW_BACKSLASH_ESCAPING_ANY_CHARACTER);

    return builder.build();
}

请求映射接口方法

@ApiOperation(value = "Returns the toll cost breakdown for a journey", notes = "", response = TotalCost.class, tags={ "pricing", })
@ApiResponses(value = { 
    @ApiResponse(code = 200, message = "successful operation", response = TotalCost.class) })
@RequestMapping(value = "/pricing/journeyCost",
    produces = { "application/json" }, 
    consumes = { "application/vnd.toll-pricing+json" },
    method = RequestMethod.POST)
ResponseEntity<TotalCost> getTollBreakdownFromEncodedPoly(@ApiParam(value = "Request object representing the journey" ,required=true ) @RequestBody Journey body);

我在另一个用户链接给我的另一个stackoverflow问题中找到了答案--https://stackoverflow.com/a/45157169/2073800

我只需将以下@bean添加到我的@配置中

@Bean
public HttpMessageConverters customConverters() {
    Jackson2ObjectMapperBuilder builder = new Jackson2ObjectMapperBuilder();
    builder.featuresToEnable(
      JsonParser.Feature.ALLOW_BACKSLASH_ESCAPING_ANY_CHARACTER);

    final AbstractJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter(builder.build());
    converter.setSupportedMediaTypes(Collections.singletonList(MediaType.valueOf("application/vnd.toll-pricing+json")));

    return new HttpMessageConverters(converter);
}
