使用Jackson将POJO序列化为xml时删除xml包装器

Question

我必须接受一个java对象并将其序列化为xml字符串。expect xml必须如下所示：

 <close_trailer_results>  
     <detl_code_load_cond_stat>CLSD</detl_code_load_cond_stat>  
     <detl_code_serv_type>GND</detl_code_serv_type>  
     <detl_code_due_sort>PRE</detl_code_due_sort>   
     <due_dt_gmt>2018-12-12 08:00:00</due_dt_gmt>   
     <org_id_next_sort>441</org_id_next_sort>  
 </close_trailer_results>

实际的xml如下所示：

> <close_trailer_results>
>     <LoadCloseTrailerResponseXml> 
>        <detl_code_load_cond_stat>CLSD</detl_code_load_cond_stat> 
>        <detl_code_serv_type>OVN</detl_code_serv_type> 
>        <detl_code_due_sort>MID</detl_code_due_sort>
>        <due_dt_gmt>2019-03-19 07:59:43</due_dt_gmt> 
>        <org_id_next_sort>61</org_id_next_sort>
>     </LoadCloseTrailerResponseXml> </close_trailer_results

@JsonPropertyOrder({"detl_code_load_cond_stat", "detl_code_serv_type", "detl_code_due_sort", "due_dt_gmt", "org_id_next_sort"})
 public class LoadCloseTrailerResponseXml {

        private String detl_code_load_cond_stat;    
        private String detl_code_serv_type; 
        private String detl_code_due_sort;
        private String due_dt_gmt;
        private Integer org_id_next_sort;
      ...just getters and setters
    }

XmlMapper xmlMapper = new XmlMapper();
        xmlMapper.setSerializationInclusion(Include.NON_NULL);

        LoadCloseTrailerResponseXml responseTrailer = new LoadCloseTrailerResponseXml();
        responseTrailer.setDetl_code_load_cond_stat(trailerResponse.getTrailer().getDetlCodeLoadCondStat());
        responseTrailer.setDetl_code_serv_type(trailerResponse.getTrailer().getDetlCodeServType());
        responseTrailer.setDetl_code_due_sort(trailerResponse.getTrailer().getDetlCodeDueSort());
        responseTrailer.setDue_dt_gmt(trailerResponse.getTrailer().getDueDateGmt());
        responseTrailer.setOrg_id_next_sort(trailerResponse.getTrailer().getOrgIdNextSort());

JacksonXmlModule xmlModule = new JacksonXmlModule();
xmlModule.setDefaultUseWrapper(false);
ObjectMapper xmlMapper = new XmlMapper(xmlModule);

xmlMapper.configure(SerializationFeature.WRAP_ROOT_VALUE, false);

Answer 1

我在网上读到，当从POJO创建xml文件时，Jackson会在xml文件中添加根标记，无论您是否设置根标记。如果不设置，它将是类名。我的解决方案是创建具有这些根标记的xml字符串，并执行一个字符串函数来删除根标记。
