PrimeFaces LazyDataModel在添加OmniFaces後，不再調用load（）方法

PrimeFaces LazyDataModel在將OmniFaces jar添加到pom.xml之前工作。它調用load()方法LazyDataModel。PrimeFaces LazyDataModel在添加OmniFaces後，不再調用load（）方法

LazyPostDataModel.java

public class LazyPostDataModel extends LazyDataModel<Post> { 
    private PostService postService; 
    private PostCriteria postCriteria; 

    public LazyPostDataModel(PostService postService, PostCriteria postCriteria) { 
     this.postCriteria = postCriteria; 
     this.postService = postService; 
    } 

    @Override 
    public List<Post> load(int first, int pageSize, String sortField, SortOrder sortOrder, Map<String,Object> filters) { 
     //other process 
    } 
}

我只是添加下面的依賴到的pom.xml的OmniFaces。它不調用load()方法。

      </p:column> 
     </p:dataTable> 
    </p:outputPanel> 
</h:form>

ManagePostActionBean.java

@Named(value = "ManagePostActionBean") 
@ViewScoped 
public class ManagePostActionBean { 
    @Inject 
    private PostService postService; 
    private LazyDataModel<Post> postDataModel; 
    private PostCriteria postCriteria; 

    public void onLoad() { 
     System.out.println("ManagePostActionBean Init...."); 
     postCriteria = new PostCriteria(); 
     postDataModel = new LazyPostDataModel(postService, postCriteria); 
    } 

    public LazyDataModel<Post> getPostDataModel() { 
     return postDataModel; 
    } 

    public PostCriteria getPostCriteria() { 
     return postCriteria; 
    } 

    public void setPostCriteria(PostCriteria postCriteria) { 
     this.postCriteria = postCriteria; 
    } 

    public void search() { 
     resetPagination(); 
     postDataModel = new LazyPostDataModel(postService, postCriteria); 
    } 
}

您是否在TomEE中手動將JSF從2.1升級到2.2？如果是這樣，究竟如何？默認情況下，TomEE 1.x不是JSF 2.2，而是JSF 2.1，然後您應該使用OmniFaces 1.x而不是2.x，或者將服務器遷移到TomEE 7.x. – BalusC

@BalusC我只是手動在pom.xml中添加com.sun.face 2.2。它不行嗎？ – CycDemo

否......'provided'意思是「目標運行時（appserver）已經提供它」。此外，TomEE 1.x提供了Apache MyFaces（org.apache.myfaces），而不是Oracle Mojarra（com.sun.faces）。我只是感到驚訝，你沒有看到部署過程中的例外，因爲這個密切相關的問題：http://stackoverflow.com/q/35226794 – BalusC

您正在使用隨JSF 2.1（Apache MyFaces）提供的TomEE 1.x。

OmniFaces 2.2 requires JSF 2.2。

你有2種選擇：

下調至2.1 OmniFaces。儘管OmniFaces 2.x正式需要JSF 2.2，但OmniFaces 2.0和2.1版本沒有部署時間的JSF 2.2依賴關係。 OmniFaces版本2.2與<o:viewAction>標記第一個版本以在部署期間需要JSF 2.2。
升級到TomEE 7.x，這是第一個實現Java EE 7的版本，因此也是固有的JSF 2.2。目前只有available作爲M1發佈。最終版本預計在幾個月內。
