Question

PrimeFaces LazyDataModel在将OmniFaces jar添加到pom.xml之前工作。它调用load()的{{1}}方法。

LazyPostDataModel.java

LazyDataModel

我只是将以下依赖项添加到OmniFaces的pom.xml中。它不会调用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 } }方法。

load()

post.xhtml

ManagePostActionBean.java

<h:form id="postTableForm">
    <p:inputText value="#{ManagePostActionBean.postCriteria.name}"/>
    <p:commandButton value="Search" action="#{ManagePostActionBean.search}" update="postTable"/>
    <p:outputPanel id="listPanel">
        <p:dataTable var="post" value="#{ManagePostActionBean.postDataModel}" id="postTable"
            paginator="true" style="width:100%;" lazy="true"
            rows="10"
            paginatorTemplate="{CurrentPageReport}  {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
            rowsPerPageTemplate="10, 20, 30, 40, 50, 100" rowIndexVar="index">
            <p:column headerText="No" style="width:50px;">
                <h:outputText value="#{index + 1}" />
            </p:column>
            <p:column headerText="Name">
                <h:outputText value="#{post.name}" />
            </p:column>
            <p:column headerText="Description">
                <h:outputText value="#{post.description}" />
            </p:column>
        </p:dataTable>
    </p:outputPanel>
</h:form>

我的环境是

@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);
    }
}

的pom.xml

JSF 2.2
Primefaces 5.0
JDK 1.7
apache-tomee-webprofile-1.7.3 (TomEE)

Answer 1

您使用的是TomEE 1.x，它随JSF 2.1（Apache MyFaces）一起提供。

OmniFaces 2.2 requires JSF 2.2。

您有两个选择：

降级为OmniFaces 2.1。即使OmniFaces 2.x正式要求JSF 2.2，OmniFaces版本2.0和2.1也没有部署时间JSF 2.2依赖项。 OmniFaces 2.2版带有<o:viewAction>标记在部署期间需要JSF 2.2的第一个版本。
升级到TomEE 7.x，这是实现Java EE 7的第一个版本，因此也就是JSF 2.2。 M1版本目前只有available。预计最终版本将在几个月内发布。

添加OmniFaces后，PrimeFaces LazyDataModel＃load（）方法不再被调用
