在我的JSF应用程序中,有一个Filter用于检查authenticati0n进程.身份验证失败时,筛选器重定向到login.xhtml.

如何FacesMessage从我的登录页面传递Filter？

虽然,我在下面使用,但不行.

FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_ERROR, message, null));

AuthenticationFilter.java

public class AuthenticationFilter implements Filter  {
    private FilterConfig config;
    private ServletContext servletContext;

    public void init(FilterConfig filterConfig) {
        config = filterConfig;
        servletContext = config.getServletContext();
    }

    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) {
            ...
            FacesContext.getCurrentInstance().addMessage(null, new …

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);
}

我想在Primefaces列组中设置货币格式而不获取字符串(带货币格式)值表单JSF Backing Bean.

如果无法在页面中设置货币格式,我将采用货币格式的字符串值,如下所示.

public String getCurrencyFormatString(Double value) {
    DecimalFormat formatter = new DecimalFormat("##,###.00");
    return formatter.format(value);
}


<p:dataTable id="paymentDataTable" var="payment" value="#{PaymentActionBean.paymentList}">
    <!--Other six columns-->

    <p:column headerText="Total">  
        <h:outputText value="#{payment.totalAmount}">
             <f:convertNumber pattern="#{ApplicationSetting.currencyFormat}"/>
        </h:outputText>
    </p:column>  
    <p:columnGroup type="footer">  
        <p:row>  
            <p:column colspan="7" footerText="Total:" style="text-align:right"/>  
            <p:column footerText="#{PaymentActionBean.grandTotalAmount}" style="text-align:right">
                <!--How Can I put number format (##,###.00) for grand total amount? -->
            </p:column>
        </p:row>  
    </p:columnGroup>                                
<p:dataTable>

根据以下信息，kubernetes-dashboard创建。我开始kubectl prox访问仪表板

[root@master ~]# kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/master/aio/deploy/recommended/kubernetes-dashboard.yaml

当我去下面的网址

http://192.168.88.43:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/

我明白了

我在运行以下查询时收到错误消息MSSQL Server 2005.

错误消息是Incorrect syntax near ','.我觉得查询还可以.但我不知道为什么会出错.

INSERT INTO PERSON (ID, EMP_NAME) VALUES ('E001', 'AAA'), ('E002', 'BBB');

SQL Server不支持？

我在网上搜索记录器配置Jboss 7.如何一起使用日期和大小配置记录器.

我用下面的内存设定standalone.con.bat的JBoss 7.1.1 Final.

set "JAVA_OPTS=-Xms1024M -Xmx2048M -XX:MaxPermSize=512M -XX:MaxHeapSize=512M"

我的生产服务器可以超过4G或更高.但是,我无法启动服务器.超过70个用户可以同时访问上传文件.

错误:

 Error occurred during initialization of VM
 Incompatible minimum and maximum heap sizes specified

如何设置大内存？我不确定此设置是否是用户和服务器规范之间的合适解决方案.有人向我建议？

是否有可能通过编程方式知道在JPA中使用哪个数据库服务器？我认为,有一种方法,否则,JPA不能转换JPQL到native query在运行时.我的程序也需要知道DB Server Type.该功能有什么功能吗？

我用eclipseLink&jpa 2.0

我的预期计划是:

EntityManagerFactory emf = Persistence.createEntityManagerFactory("JPA");
String dbPlatform = emf.getDBPlatform();
System.out.println(dbPlatform);

输出:

Oracle
MySql
MSSql
DB2
....

请自由评论我.以下程序出了什么问题.它给出了不同的圆形结果.

public class Test {
    public static String round(double value, int places) {
        BigDecimal bd = new BigDecimal(value);
        bd = bd.setScale(places, RoundingMode.HALF_UP);
        return bd.toPlainString();
    }

    public static void main(String[] args) throws Exception {
        double value1 = 1.1234565;
        System.out.println(round(value1, 6));
        double value2 = 1.1235;
        System.out.println(round(value2, 3));
    }
}

为什么这样出来？

1.123457
1.123   --> Actually, I expect 1.124

在Doc(eclipse)

export enum Type {
    TYPE_1 : "Apple",
    TYPE_2 : "Orange",
    TYPE_3 : "Banana"
}

当我登录时Type.TYPE_1，toString默认调用方法。

console.log(Type.TYPE_1 + " is " + Type.TYPE_1.toString());

Output => Apple is Apple

我的期望是结果就像

Output : TYPE_1 is Apple

如何将密钥记录/获取TYPE_1为字符串？

有没有办法override method像下面那样做？

export enum Type {
    TYPE_1 : "Apple",
    TYPE_2 : "Orange",
    TYPE_3 : "Banana"

    toString() {
        this.key + " is " + this.toString();
        <or>
        this.key + " is " + this.value();
    }
}

我已经在谷歌上搜索了，我还没有确定。

目的是在UI中显示
