我正在为我的 webapp 使用 Primefaces 数据表，我想在单击<p:commandButton value="Add" actionListener="#{accountBean.testAdd}" update="accountTable" />添加新数据后重新加载不工作后重新加载数据表，我不知道错误是什么，但这是我的 bean：

@Named
@ViewScoped
public class AccountBean implements Serializable {

    private List<AccountModel> accountModels;
    private AccountModel accountModel = new AccountModel();

    @Inject
    transient private AccountServices accountServices;

    @PostConstruct
    public void init() {
        try {
            this.accountModels = accountServices.getAccountTable();
        } catch (JsonProcessingException | EndpointException ex) {
            Logger.getLogger(AccountBean.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
    
    public void testAdd() {
        try {
            System.out.println("SUBMITTED!");
            accountModel.setBalance(BigDecimal.ZERO);
            accountModel.setAccountId("111");
            accountModel.setAllowNegativeBalance(true);
            accountModel.setName("Reload");
            accountModel.setBirthDate(LocalDate.now());
            accountModel.setAddress("Tasik Reload");
            accountServices.registerAccount(accountModel);
            System.out.println("END HERE");
        } catch (JsonProcessingException | EndpointException ex) {
            Logger.getLogger(AccountBean.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

    // Setter Getter 
}

这是我的 index.xhtml

<h:form id="dataTableAccount">
    <div class="card">
        <p:commandButton value="Add" actionListener="#{accountBean.testAdd}" update="accountTable" />
        <p:dataTable id="accountTable" lazy="true" var="accountModel" value="#{lazyAccountView.lazyModel}" paginator="true" rows="10"
                     paginatorTemplate="{RowsPerPageDropdown} {FirstPageLink} {PreviousPageLink} {CurrentPageReport} {NextPageLink} {LastPageLink}"
                     rowsPerPageTemplate="5,10,15">
            <p:column headerText="Account ID" sortBy="#{accountModel.accountId}" filterBy="#{accountModel.accountId}">
                <h:outputText value="#{accountModel.accountId}" />
            </p:column>

            <p:column headerText="Name" sortBy="#{accountModel.name}" filterBy="#{accountModel.name}">
                <h:outputText value="#{accountModel.name}"  />
            </p:column>

            <p:column headerText="Balance">
                <h:outputText value="#{accountModel.balance}" />
            </p:column>

            <p:column headerText="Allow Negative Balance" sortBy="#{accountModel.allowNegativeBalance}" filterBy="#{accountModel.allowNegativeBalance}">
                <h:outputText value="#{accountModel.allowNegativeBalance}" />
            </p:column>
        </p:dataTable>
    </div>
</h:form>

我的帐户模型：

public class AccountModel implements Serializable{
    
    public String accountId;
    public String name;
    public String address;
    @JsonFormat(pattern = Json.JSON_FORMAT_DATE)
    @Temporal(TemporalType.DATE)
    @JsonDeserialize(using = LocalDateDeserializer.class)
    @JsonSerialize(using = LocalDateSerializer.class)
    public LocalDate birthDate;
    public boolean allowNegativeBalance;
    public BigDecimal balance;
    
    // Setter Getter

}

还有我的 AccountServices

@Named
@ApplicationScoped
public class AccountServices {

    @Inject
    private RestMockvaEndpoint restMockvaEndpoint;

    public AccountModel registerAccount(AccountModel accountModel) throws JsonProcessingException, EndpointException {
        AccountModel account = new JsonResponseReader(restMockvaEndpoint.send(new EndpointRequestBuilder()
                .method("POST")
                .content(Json.getWriter().writeValueAsBytes(accountModel), MediaType.APPLICATION_JSON)
                .resource("/account")
                .build())).getContentObject(AccountModel.class);
        return account;
    }
}

任何想法？

已编辑：当我单击按钮时，顺便说一句，我的日志上没有任何错误，但数据表仍未重新加载。

通过调用this.accountModels = accountServices.getAccountTable();解决testAdd()。谢谢大家！我很感激你。
