的SAXException根元素在彈簧web服務解組

我有彈簧寧靜web服務，其具有以下映射：的SAXException根元素在彈簧web服務解組

聯繫人類：

public class Contacts implements Serializable {

    public Contacts() {

    public Contacts(List<Contact> contacts) { 
     this.contacts = contacts;

Contact類：

    private static final long serialVersionUID = 1L;

然後，當我試圖通過org.springframework.web.client.RestTemplate獲取Java對象（在客戶端應用程序）我有例外如下：

Exception in thread "main" 
org.springframework.http.converter.HttpMessageNotReadableException: 
Could not read [class com.example.web.Contacts]; nested exception is 
org.springframework.oxm.UnmarshallingFailureException: SAX reader 
exception; nested exception is org.xml.sax.SAXException: The class for 
the root element 'Contacts' could not be found. at 
org.springframework.http.converter.xml.MarshallingHttpMessageConverter.re 
adFromSource(MarshallingHttpMessageConverter.java:134) 
    ...

我相信錯誤的是我的映射文件。正如你可以看到我有三重聯繫人標記甚至在映射文件中我有其他名稱..有誰知道什麼可能是有這種異常/錯誤的XML格式的原因？

這裏有很多問題，但是您所討論的具體問題可能是由於其他控制器不依賴於實體模型而引起的。該錯誤告訴你，顯式地，它找不到聯繫人的類定義 - 它具有映射文件，這就是爲什麼它試圖綁定到聯繫人，但它無法在類路徑中找到Contacts.class。 –

問題是我在客戶端應用程序中有這個類。與WebService中的包相同。我在想，XML輸出應該是： ... 正如你可以看到我有三重這是不明確的，我 - 即使我有這個映射文件.. – Gazeciarz

然後綁定外部端子到一個ContactsHolder或類似的東西，或者在將它傳遞給解組器之前使用某種過濾器對xml進行預處理。添加額外的綁定是我認爲最簡單的。另外，在綁定的bind-xml標籤中可能存在拼寫錯誤 - 不應該是「聯繫」複數？ –

發生什麼事情是，當unmarshaller正在尋找班級時，他正在尋找別名「Contacts」，就像在XML中一樣。他在緩存中的是「聯繫人」映射，它與「聯繫人」不一樣。編組庫不像unmarshaller一樣。可能是在配置中出現錯誤.. 我所做的是將實現更改爲jaxb我將@XMLRootElement和@XMLElement放在模型類上，並完全移除mvc中的messageConverters配置：註釋驅動（也映射xml文件）。在客戶端應用程序上，我將messageConverter更改爲：

<bean id="restTemplate" class="org.springframework.web.client.RestTemplate"> 
     <property name="messageConverters"> 
      <list> 
       <bean 
        class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter"> 
        <property name="marshaller" ref="jaxb2Marshaller" /> 
        <property name="unmarshaller" ref="jaxb2Marshaller" /> 

       </bean> 
      </list> 
     </property> 
    </bean> 
    <bean id="jaxb2Marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller"> 
     <property name="classesToBeBound"> 
      <list> 
       <value>com.example.web.model.Contact</value> 
       <value>com.example.web.Contacts</value> 
      </list> 
     </property> 
    </bean>

而且一切正常。
