使用JsonFactory. Feature设置在Spring Boot中配置Jackson ObjectMapper

我知道如何在Spring Boot中通过应用程序属性配置JacksonObjectMapperhttps://docs.spring.io/spring-boot/docs/current/reference/html/howto-spring-mvc.html#howto-customize-the-jackson-objectmapper.

如何以这种方式控制JacksonJsonFactory. Feature？

在Spring 4.3.14Jackson2ObjectMapperBuilder中，通过其默认构造函数实例化ObjectMapper，即不传递JsonFactory。这种行为后来显然被改变/修复了：https://github.com/spring-projects/spring-framework/blob/master/spring-web/src/main/java/org/springframework/http/converter/json/Jackson2ObjectMapperBuilder.java#L621

@Bean
public ObjectMapper tolerantObjectMapper() {
    log.info("Creating Object mapper");
    final JsonFactory jsonFactory = new JsonFactory();
    jsonFactory.enable(JsonParser.Feature.ALLOW_UNQUOTED_FIELD_NAMES);
    ObjectMapper objectMapper = new ObjectMapper(jsonFactory);
    return objectMapper;
}
