創建JAX-WS Web服務時未映射Hibernate對象

Question

我正在使用Eclipse IDE生成Java服務的Web服務，該服務有一個類，其中包含通過Hibernate映射的DAO查詢數據庫的方法。如果我在不使用所有Hibernate類型（作爲傳遞給方法或返回類型的參數）的情況下創建Web服務，那麼它會成功，如果我嘗試使用所有Hibernate bean以使其映射失敗。任何人都面臨過這個問題？

問題是我沒有在Web服務中映射的所有Hibernate對象。當我需要使用服務的客戶端使用它們時，它們當然不會有一些不明確的地方。

任何人都遇到過這個問題？

謝謝，我感謝所有幫助...

Answer 1

問題通過加入@XmlJavaTypeAdapter(TimestampAdapter.class) BUT通過創建具有其返回的java.util.Date代替java.sql.Date

Answer 2

在我的例子中第一種方法「mapVM」之類的下方返回一組「VmStatistics」的使faliure如下：

An internal error occurred during: "Generating JAX-WS Web Services". 
Unable to create JAXBContext 

而如果我關閉Hibernate對象的方法，'wmStatistics'不會在創建ws時映射。和其他對象一樣，所以我在ws中丟失了bean。

休眠邏輯位於jar文件中幷包含6個bean。

這是我的類來生成WS的（包含5種方法）

public class DBHelper { 

    public DBHelper(){} 

      public static Set<VmStatistics> mapVM(Vm vm){ 

     Set< VmStatistics> s = vm.getVmStatisticses(); 
     return s; 
    } 



    /** 
    * Loads all companies 
    * 
    * @return A list of company objects 
    */ 
    public static ArrayList<Company> getCompanyList(){ 
     ArrayList<Company> lCompanies = new ArrayList<Company>(); 

        ... 

        return lCompanies; 
    } 

    /** 
    * Loads all the available countries 
    * 
    * @return 
    * Returns a list of string objects 
    */ 
    public static ArrayList<String> getCountryList(){ 
     ArrayList<String> lCountires = new ArrayList<String>(); 

     ...  

        return lCountires; 
    } 

    /** 
    * Loads the companies of the given country name 
    * 
    * @param pCountry a given country name 
    * 
    * @return A list of company objects 
    */ 
    public static ArrayList<Company> getCompanyListByCountry(String pCountry){ 
     ArrayList<Company> lCompanies = new ArrayList<Company>(); 

        ... 
        return lCompanies; 
    } 

    /** 
    * Loads the latest reading performed in the datacenter 
    * 
    * @param pCountry 
    * A given country name 
    * 
    * @param pCompany 
    * A given company object 
    * 
    * @return The list of server objects which contains the associated VMs and the relative statistics 
    */ 
    public static Collection<Server> getCurrentReading(String pCountry, Company pCompany){ 
       ... 
       return lServer; 
    } 

} 

現在我試圖手動添加豆類的WS的模式文件和WSDL，它接受它，但在部署到Tomcat階段它給出了相同的錯誤，但由於它是一個日誌錯誤，而不是一個月食，我認爲這是更清楚明白：

我試圖通過修改sdl和模式文件，並添加不獲取類型映射......並在部署在Tomcat的臉上，它給出了相同的錯誤...也許這將更清楚sicne它是一個日誌錯誤：
