java之xml报文传值问题的解决~~~ xml格式报文请求后端

1.这里本人使用postman来请求java后端，在postman中的设置

<TradeData>
	<BaseInfo>
		<RequestDate>2017-07-06 15:47:30RequestDate>
		<TransNo>00920170627091902001TransNo>
		<UserCode>testUserCode>
		<Password>1234@abcdPassword>
	BaseInfo>
	<ContInfo>
		<AppointMentNo>HXJK0000000000000002AppointMentNo>
		<ContSource>009ContSource>
		<BizType>TBBizType>
		<DocTypeCode>A101DocTypeCode>
		<DocImgOrder>1DocImgOrder>
		<DocImgCount>10DocImgCount>	
	ContInfo>
TradeData>

使用post请求，选中Body中的row将上诉报文放入，设置请求方式为XML(这里注意：因为postman版本的不同，选择的方式也不同，有的postman中只有XML格式，而有的postman格式为XML(application/xml)和XML(test/xml)格式)，我们选用XML（application/xml）格式来请求，具体体现如下图所示：

2. 后端java控制层，这里我是用当下较流行、智能的IDEA来展示后端代码
   先来看实体类的写法。

此处为最外层的封装类

import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlProperty;
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlRootElement;
import com.sinosoft.mid.module.common.pojo.hcsimguploadnotify.request.BaseInfo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@JacksonXmlRootElement(localName = "TradeData")
@NoArgsConstructor
@AllArgsConstructor
public class TradeDataHCSImgUploadNotifyRequest {
     

    @JacksonXmlProperty(localName = "BaseInfo")
    BaseInfo baseInfo;

    @JacksonXmlProperty(localName = "ContInfo")
    ContInfo contInfo;
}

BaseInfo实体类如下：

import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlProperty;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@NoArgsConstructor
@AllArgsConstructor
public class BaseInfo {
     

    @JacksonXmlProperty(localName = "TradeCode")
    private String tradeCode;

    @JacksonXmlProperty(localName = "TransNo")
    private String transNo;

    @JacksonXmlProperty(localName = "RequestDate")
    private String requestDate;

    @JacksonXmlProperty(localName = "ResponseDate")
    private String responseDate;

    @JacksonXmlProperty(localName = "UserCode")
    private String userCode;

    @JacksonXmlProperty(localName = "Password")
    private String password;

}

ContInfo 实体类：

import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlProperty;
import com.sinosoft.mid.module.common.pojo.hcsimguploadnotify.request.DocImgInfos;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@NoArgsConstructor
@AllArgsConstructor
public class ContInfo {
     

    @JacksonXmlProperty(localName = "AppointMentNo")
    private String appointMentNo;
    @JacksonXmlProperty(localName = "ContSource")
    private String contSource;
    @JacksonXmlProperty(localName = "BizType")
    private String bizType;
    @JacksonXmlProperty(localName = "DocTypeCode")
    private String docTypeCode;
    @JacksonXmlProperty(localName = "ReqType")
    private String reqType;
    @JacksonXmlProperty(localName = "DocImgInfos")
    private DocImgInfos docImgInfos;
    @JacksonXmlProperty(localName = "DocImgOrder")
    private String docImgOrder;
    @JacksonXmlProperty(localName = "DocImgCount")
    private String docImgCount;

}

这里拾荒者有比较解释一下

3. ContInfo中的实体类DocImgInfos

import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlElementWrapper;
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlProperty;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

import java.util.List;


@Data
@NoArgsConstructor
@AllArgsConstructor
public class DocImgInfos {
     
    @JacksonXmlProperty(localName = "DocImgInfos")
    private String docImgInfos;
    @JacksonXmlProperty(localName = "DocTypeCount")
    private String docTypeCount;

    @JacksonXmlElementWrapper(useWrapping = false)
    @JacksonXmlProperty(localName = "DocImgInfo")
    private List<DocImgInfo> docImgInfo;

}

4. 关于List集合中的DocImgInfo

@Data
@NoArgsConstructor
@AllArgsConstructor
public class DocImgInfo {
     
    @JacksonXmlProperty(localName = "DocTypeCode")
    private String docTypeCode;
    @JacksonXmlProperty(localName = "DocImgPages")
    private String docImgPages;

    @JacksonXmlElementWrapper(useWrapping = false)
    @JacksonXmlProperty(localName = "DocImgPage")
    private List<DocImgPage> docImgInfo;

}

关于List中的实体类，拾荒者本人就不多解释了 ，想必都知道，就是在某一挤报文下，有多个该实体类型。只是层级不同。

本人有必要解释一下***@JacksonXmlProperty(localName = “DocImgPage”)***的意思。

由于***spring容器***的特性，实体类字段都会转小驼峰，而我们在postman中测试的时候采用的有时候是大写开头的报文。所以此注解是保证与请求一致，防止请求的时候映射器处理不到。而实体类名我们有时候也要处理使用***@JacksonXmlRootElement(localName = “TradeData”)***来控制。

5. 控制层中来设计一个方法来接收这种类型的数据：

 @Autowired
    private ImgUploadService imgUploadService;

    @SneakyThrows
    @PostMapping(value = "/upLoadImg",consumes = MediaType.APPLICATION_XML_VALUE, produces = MediaType.APPLICATION_XML_VALUE,headers ={
     "content-type=application/xml"} )
    @ResponseBody
    private TradeDataHCSImgUploadNotifyResponse upLoadImg(@RequestBody TradeDataHCSImgUploadNotifyRequest tradeData){
     
        System.out.println(tradeData);
        TradeDataHCSImgUploadNotifyResponse response = imgUploadService.upLoadImg(tradeData);
        System.out.println(response);
        return response;
    }

请求的PostMapping注解就不多解释了 本人要解释的是里面的值 特别是**headers ={“content-type=application/xml”}**要添加，防止接收数据失败，
接收到如下结果：

TradeDataHCSImgUploadNotifyRequest(baseInfo=BaseInfo(tradeCode=null, transNo=00920170627091902001, requestDate=2017-07-06 15:47:30, responseDate=null, userCode=test, password=1234@abcd), contInfo=ContInfo(appointMentNo=HXJK0000000000000002, contSource=009, bizType=TB, docTypeCode=A101, reqType=null, docImgInfos=null, docImgOrder=1, docImgCount=10))
TradeDataHCSImgUploadNotifyRequest(baseInfo=BaseInfo(tradeCode=null, transNo=00920170627091902001, requestDate=2017-07-06 15:47:30, responseDate=null, userCode=test, password=1234@abcd), contInfo=ContInfo(appointMentNo=HXJK0000000000000002, contSource=009, bizType=TB, reqType=null, docImgCount=10, docImgInfos=DocImgInfos(docImgInfos=null, docTypeCount=null, docImgInfo=[DocImgInfo(docTypeCode=A101, docImgPages=null, docImgInfo=[DocImgPage(docImgOrder=1, docImgAttachNo=null)])])))

希望对同道有所帮助。
