意外元素的錯誤進行解

Question

我要解組簡單的XML作爲貝洛奧裏藏特，但得到錯誤的

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. 

這是目前在response.xml文件中的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> 

下面是我的代碼：

WebResponse class：

WebResponse類，用於存儲所檢索的XML

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類：

Tester類

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.*; 

我使用了本網站的解決方案，但無法解決請幫助

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) 

問題是在XML中指定的名稱空間（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;

您當前的對象模型和映射不匹配的XML內容。解決此問題的一種方法是引入Status類as answered by Ash。

狀態

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; 
    } 

} 

WebResponse的

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; 
    } 

}

嘗試添加Status類，並將其放在WebResponse和字段之間。

我認爲，由於您的XML元素轉到WebResponse - > Status - > StatusCode/Description，您的WebResponse類應該只有一個字段：Status類型的「狀態」。 Status類應具有StatusCode和Description字段。

編輯：另外，我認爲@XmlElement註解去上的字段，而不是方法，但它已經有一段時間，因爲我已經做到了......
