我没有TimerServiceDispatcher在我的应用程序中创建spring bean名称.但是,JBoss抛出异常因为TimerServiceDispatcher已在此模块中定义.我不知道是什么问题.我错过了什么？我需要做什么？

我的应用程序使用Seam 2.3,Spring 3.0和JPA 2.0.我不用EJB.

在我的例子,Employee有一个OneToOne以关系Department与CascadeType.PERSIST.当我坚持多次Employee,

为什么EntityManager持续Department记录所有Employee记录？

我的期望是,如果我们使用CascadeType.PERSIST,当一个Employee被持久化时,Department将为每个Employee记录重新创建一条记录.

Employee.java

@Entity
public class Employee {
    private String id;
    private String name;
    @OneToOne(cascade = CascadeType.PERSIST)
    @JoinColumn(name = "DEP_ID", referencedColumnName = "ID")
    private Department department;

    -----
}

Department.java

@Entity
public class Department implements Serializable {
    private String id;
    private String name;
}

Test.java

public void insert() {
    em = emf.createEntityManager();
    em.getTransaction().begin();
    Department department = …

我有一个表,其中包含No,Name,Address,Phone,Email列.我想在No列中设置自动编号而不通过我的java类传递参数.是否存在EL或需要解决的问题JasperReport.我使用的是5.1版.

注意:作为简单的表,我没有提供源和模板.

我有以下带有enum集合的实体.我想用enum参数搜索用户.
用户可能拥有多个权限.当我使用参数搜索用户时Permission.APPROVE,可能有一个或多个用户拥有该权限.我怎么写JPQL查询？

User.java

@Entity
....
public class User implements Serializable {

    @ElementCollection(targetClass = Permission.class)
    @Enumerated(EnumType.STRING)
    @CollectionTable(name = "USER_PERMISSION", joinColumns = @JoinColumn(name = "PERMISSION", referencedColumnName = "ID")) 
    private List<Permission> permisssionList;
}

Permission.java

public enum Permission {
    REGISTER, APPROVE, REJECT, CONFIRM;
}

怎么写 ？

public List<User> findUserList(Permission permission) { 
    Query q = em.createQuery(.....);
    result = q.getResultList();
}

如何JSF在eclipse中格式化代码？

我已经尝试如下:

• 在Eclipse中格式化XML代码

我的XML Editor配置设置是:

• 线宽120
• 在像Checked这样的新组件上拆分多个属性
• 对齐多功能使用在线元件标签最终托架 经过
• 清除所有空行检查

如果我这样做Ctrl + Shif + F,eclipse格式化代码如下.

<tr>
    <td><h:outputText value="#{label['MANAGE_USER_TITLE']}"
            styleClass="table-title" /></td>

</tr>

我的期望格式是,之后 Ctrl + Shif + F

<tr>        
    <td>
        <h:outputText value="#{label['MANAGE_USER_TITLE']}" styleClass="table-title" /> 
                ?
                This line may be wrap base on line size.
    </td>
</tr>

我该怎么做？有插件吗？我已经尝试了HTML Tidy,我只能格式化HTML,而不是JSF代码.

在我AuthenticationFilter重定向到登录页面后,我想退出给用户.

这就是为什么,我把identity.logout();我的预渲染方法checkPermission(...)的login.xhtml.

但是,我得到ViewExpiredException了用户再次登录的时间.

我的问题是

1:如果我不这样做identity.logout();,用户再次重新登录,因为旧的用户会话仍然存在. 2:如果我这样做identity.logout();,我会ViewExpiredException在用户再次登录时获得.

AuthenticationFilter.java

public class AuthenticationFilter implements Filter  {
    .....

    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
        HttpServletRequest httpRequest = (HttpServletRequest) servletRequest;
        HttpServletResponse httpResponse = (HttpServletResponse) servletResponse;
        HttpSession session = httpRequest.getSession();
        User user = (User) session.getAttribute(Constants.LOGIN_USER);
        if (user == null) {
            session.setAttribute(Constants.MESSAGE_ID, MessageId.REQUIRED_TO_LOGIN);
            String loginView = httpRequest.getContextPath() + Constants.LOGIN_PAGE;
            httpResponse.sendRedirect(loginView);
        } else if …

想拥有以下数据表结构:

+--------------------------------------------------------------+
|       dynamic      |       dynamic      |      dynamic       |
|--------------------------------------------------------------|
| col1 | col2 | col3 | col1 | col2 | col3 | col1 | col2 | col3 |     
|--------------------------------------------------------------|
| data | data | data | data | data | data | data | data | data |

原因是,我不知道在我请求数据库之前必须显示多少列.col1,col2,col3中的列始终相同.

我尝试使用以下数据表:

<h:form id="form">    
        <h:panelGrid columns="3" style="margin:10px 0">
            <p:outputLabel for="template" value="Adid:" style="font-weight:bold"/>
            <p:inputText id="template" value="#{reportingView.adId}" size="50"/>
            <p:commandButton update="kpi_table" actionListener="#{reportingView.updateColumns}" value="Create Data" process="@parent" icon="ui-icon-refresh" oncomplete="PF('carsTable').clearFilters()"/>
        </h:panelGrid>

        <p:dataTable id="reportingTable" var="pi" value="#{reportingView.indicators}" widgetVar="indicatorTable" filteredValue="#{reportingView.filteredValues}"> …

如果我使用如下,我没有错误,没有输出.为什么p:panelGrid不用ui:repeat？

注意:我不想使用c:forEach因为我已经面临很多JSF问题.

<p:panelGrid>
    <ui:repeat value="#{MyBean.dataList}" var="data">
        <p:row>
            <p:column>
                <h:outputText value="#{data.name}"/>
            </p:column>
            <p:column>
                <h:outputText value="#{data.description}"/>
            </p:column>
        </p:row>
    </ui:repeat>
</p:panelGrid>

MyBean.java

public List<Data> getDataList(){
    List<Data> result = new ArrayList<Data>();
    result.add(new Data("Name 1", "Description 1"));
    result.add(new Data("Name 2", "Description 2"));
    result.add(new Data("Name 3", "Description 3"));
    result.add(new Data("Name 4", "Description 4"));
    return result;
}   

带有primefaces的预期输出

我想在jasper报告中使用自定义字体.Myanmar3是缅甸的标准字体.一切都很好,但ReportTitle必须Myanmar Font与Myanmar3. Google也Myanmar3用于缅甸当地.

将报告导出为html文件时.它可以显示报告标题.但是,导出的PDF文件无法正确显示.

在浏览器中.

在PDF中

public void report() throws Exception {
    List<SalesReport> saleReports = salesReportService.findSalesReport(new SalesReportCriteria());
    InputStream inputStream = new FileInputStream("report-template/saleReportTemplate.jrxml");
    String outputFilePdf = "D:/temp/BasicReport.pdf";
    String outputFileHtml = "D:/temp/BasicReport.html";
    Map paramMap = new HashMap();
    paramMap.put("ReportTitle", "\u1005\u101B\u1004\u103A\u1038\u1021\u1004\u103A\u1038\u1019\u103B\u102C\u1038\u1011\u100A\u103A\u101E\u103D\u1004\u103A\u1038\u1001\u103C\u1004\u103A\u1038");
    paramMap.put("TableDataSource", new JRBeanCollectionDataSource(saleReports));
    JasperDesign jasperDesign = JRXmlLoader.load(inputStream);
    JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
    JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, paramMap, new JRBeanCollectionDataSource(saleReports));
    JasperExportManager.exportReportToPdfFile(jasperPrint, outputFilePdf);
    JasperExportManager.exportReportToHtmlFile(jasperPrint, outputFileHtml);
}

saleReportTemplate.jrxml

<?xml version="1.0" encoding="UTF-8"?>
<jasperReport …

我想解决以下condtion字符串.因为我想在我的项目中支持动态条件.

a != 0 && b > 5

我的预期计划是

public boolean resolve() {
    String condition = "a != 0 && b > 5";
    Map<String, Object> paramMap = new HashMap<String, Object>;
    paramMap.put("a", 2);
    paramMap.put("b", 6);
    boolean result = ConditionResolver.resolve(condition, paramMap);
    if(result) {
        //do something
    }
} 

更新:

我不是要解决数学等式,如下所示

((a + b) * y) /x
