java-解组时发生意外的元素错误

作者:互联网

我应该将简单的xml解组为belo,但由于出现错误

Exception in thread "main" javax.xml.bind.UnmarshalException: unexpected element (uri:"http://example.com/service/response/v1", local:"WebResponse"). Expected elements are <{http://example.com/service/request/v1}WebResponse>
    at com.sun.xml.bind.v2.runtime.unmarshaller.UnmarshallingContext.handleEvent(UnmarshallingContext.java:603)

I tried the solutions in this site but could not solve pls help.

这是response.xml文件中存在的xml

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?> 
- <WebResponse xmlns="http://example.com/service/response/v1">
- <Status>
  <StatusCode>0</StatusCode> 
  <Description>Transaction was successful</Description> 
  </Status>
  </WebResponse>

下面是我的代码:

WebResponse类:

用于存储检索到的xml的webresponse类

import javax.xml.bind.annotation.*;

@XmlRootElement(name="WebResponse")
public class WebResponse {

    private long statusCode;
    private String description;
    @XmlElement(name= "StatusCode")
    public long getStatusCode() {
        return statusCode;
    }
    public void setStatusCode(long statusCode) {
        this.statusCode = statusCode;
    }
    @XmlElement(name= "Description")
    public String getDescription() {
        return description;
    }
    public void setDescription(String description) {
        this.description = description;
    }

WebResponseMain类:

测试员班

import javax.xml.bind.Unmarshaller;
import javax.xml.bind.JAXBContext;

import java.io.FileReader;
import com.example.WebResponse;


public class WebResponseMain {

    public static void main(String[] args) throws Exception{
        JAXBContext context = JAXBContext.newInstance(WebResponse.class);
        Unmarshaller um = context.createUnmarshaller();
        WebResponse WR = (WebResponse) um.unmarshal(new FileReader("c:/tem/Response.XML"));
        System.out.println("StatusCode: " + WR.getStatusCode() + " Description "
                 +WR.getDescription());

    }

}

package-info.java:

@XmlSchema(namespace = "http://example.com/service/request/v1",elementFormDefault=XmlNsForm.QUALIFIED)



package com.example;

import javax.xml.bind.annotation.*;

我使用了本网站上存在的解决方案,但无法解决,请帮助

解决方法:

第1部分

Exception in thread "main" javax.xml.bind.UnmarshalException: unexpected element (uri:"http://example.com/service/response/v1", local:"WebResponse"). Expected elements are <{http://example.com/service/request/v1}WebResponse>
    at com.sun.xml.bind.v2.runtime.unmarshaller.UnmarshallingContext.handleEvent(UnmarshallingContext.java:603)

问题在于XML中指定的名称空间(response / v1和request / v1).

<WebResponse xmlns="http://example.com/service/response/v1">

和package-info不同

@XmlSchema(namespace = "http://example.com/service/request/v1", elementFormDefault = XmlNsForm.QUALIFIED)
package com.example;

第2部分

您当前的对象模型和映射与XML内容不匹配.解决此问题的一种方法是引入状态类as answered by Ash.

状态

import javax.xml.bind.annotation.XmlElement;

public class Status {

    private long statusCode;
    private String description;

    @XmlElement(name = "StatusCode")
    public long getStatusCode() {
        return statusCode;
    }

    public void setStatusCode(long statusCode) {
        this.statusCode = statusCode;
    }

    @XmlElement(name = "Description")
    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

}

Web响应

import javax.xml.bind.annotation.*;

@XmlRootElement(name = "WebResponse")
public class WebResponse {

    private Status status;

    @XmlElement(name="Status")
    public Status getStatus() {
        return status;
    }

    public void setStatus(Status status) {
        this.status = status;
    }

}
