我想使用JavaFX创建带有类似于Firefox配置面板的图标的选项卡面板:

有没有我可以用来看看如何实现这个的例子？

我想实现这个代码

public void testGetExchangeRate() throws Exception
{
    ECKey key = KeyUtils.createEcKey();

    String clientName = "server 1";
    BitPay bitpay = new BitPay(key, clientName);

    if (!bitpay.clientIsAuthorized(BitPay.FACADE_MERCHANT))
    {
        // Get Merchant facade authorization code
        String pairingCode = bitpay.requestClientAuthorization(
            BitPay.FACADE_MERCHANT);

        // Signal the device operator that this client needs to
        // be paired with a merchant account.
        System.out.print("Info: Pair this client with your merchant account using the pairing Code: " + pairingCode);
        throw new BitPayException("Error:client is not authorized for Merchant facade");
    } …

我想设置电子表格单元格背景颜色和文本大小.我使用这个Java代码将文本设置为单元格,但我找不到如何设置样式的解决方案.

CellData setUserEnteredValue = new CellData()
            .setUserEnteredValue(new ExtendedValue()
                .setStringValue("cell text"));

有什么解决方案吗？

代码重构后，当我尝试编译 Maven 项目时出现此错误：

"C:\Program Files\Java\jdk-14\bin\java.exe" -Dmaven.multiModuleProjectDirectory=C:\Users\plte1219\Desktop\CJM\media_auth -Xmx1024m -XX:MaxPermSize=512m "-Dmaven.home=C:\Program Files\JetBrains\IntelliJ IDEA 2019.3.1\plugins\maven\lib\maven3" "-Dclassworlds.conf=C:\Program Files\JetBrains\IntelliJ IDEA 2019.3.1\plugins\maven\lib\maven3\bin\m2.conf" "-Dmaven.ext.class.path=C:\Program Files\JetBrains\IntelliJ IDEA 2019.3.1\plugins\maven\lib\maven-event-listener.jar" "-javaagent:C:\Program Files\JetBrains\IntelliJ IDEA 2019.3.1\lib\idea_rt.jar=59675:C:\Program Files\JetBrains\IntelliJ IDEA 2019.3.1\bin" -Dfile.encoding=UTF-8 -classpath "C:\Program Files\JetBrains\IntelliJ IDEA 2019.3.1\plugins\maven\lib\maven3\boot\plexus-classworlds-2.6.0.jar;C:\Program Files\JetBrains\IntelliJ IDEA 2019.3.1\plugins\maven\lib\maven3\boot\plexus-classworlds.license" org.codehaus.classworlds.Launcher -Didea.version2020.1.2 clean package

我有一个简单的JSF输入表单到编辑页面和Validator,它检查重复的值:

<td>Name</td>
<td>
    <h:outputText value="#{ud.name}"
                  rendered="#{not DCProfileTabGeneralController.editable}" />
    <h:inputText id="dcname" value="#{ud.name}" rendered="#{DCProfileTabGeneralController.editable}"
                 validator="#{ValidatorDatacenterController.validateDatacenterName}" autocomplete="off">
        <f:ajax event="blur" render="dcnamevalidator" />
    </h:inputText>
    <h:message id="dcnamevalidator" for="dcname" />
</td>

public void validateDatacenterName(FacesContext context, UIComponent component, Object value){
....
}

我感兴趣的是有没有办法发送第二个值用于验证过程？

我有这个未修饰的窗口:

public static void initStartPage(final Stage primaryStage) {

        final Stage startPage = new Stage();
        startPage.initStyle(StageStyle.UNDECORATED);
        //startPage.initOwner(primaryStage);
        //startPage.toFront();
        Scene scene = new Scene(agentsPanel(), 900, 500);
        startPage.setScene(scene);
        startPage.show();

    }

我很感兴趣如何让它拖动可拖动？我希望我将鼠标光标放在它上面以拖动它来改变它的位置.

PS

我测试了这个解决方案,但它不起作用:

private static FlowPane flow;
    private static BorderPane bpi;

    public static void initStartPage(final Stage primaryStage) {

        final Stage startPage = new Stage();
        startPage.initStyle(StageStyle.UNDECORATED);
        startPage.initOwner(primaryStage);
        //startPage.toFront();
        Scene scene = new Scene(agentsPanel(primaryStage), 900, 500);
        startPage.setScene(scene);
        startPage.show();

    }

    private static double xOffset = 0;
    private static double yOffset = 0;

    public static BorderPane agentsPanel(final …

我发现这个SQL查询显示MySQL正常运行时间

SHOW GLOBAL STATUS LIKE 'Uptime';

但我得到的价值2059555

我怎么能在几天内转换它？

我想使用Apache Shiro进行数据库身份验证.但我无法进行数据库设计更改.我想使用我的自定义SQL命令和Java逻辑来验证用户.这可能吗？我在shiro.ini中尝试了这个配置:

saltedJdbcRealm = com.crm.web.authentication.JdbcRealm

和自定义Java类:

public class JdbcRealm extends AuthorizingRealm
{
    @Resource(name = "jdbc/DefaultDB")
    private DataSource dataSource;

    protected static final String DEFAULT_AUTHENTICATION_QUERY = "select passwd from user where username = ?";

    protected static final String DEFAULT_SALTED_AUTHENTICATION_QUERY = "select passwd, passwd_salt from user where username = ?";

    protected static final String DEFAULT_USER_ROLES_QUERY = "select role_name from user_roles where username = ?";

    protected static final String DEFAULT_PERMISSIONS_QUERY = "select permission from roles_permissions where role_name = ?";
    private static final Logger log …

我想配置Wildfly 14以使用加密的JDBC连接.我试过这个:

MariaDB的:

mysql -u root -p
CREATE USER 'wildfly' IDENTIFIED BY 'qwerty';
CREATE DATABASE production_gateway;
GRANT ALL PRIVILEGES ON production_gateway.* TO 'wildfly'@'%' REQUIRE SSL;
FLUSH PRIVILEGES;

创建证书:

mkdir -p /etc/mysql/ssl
cd /etc/mysql/ssl

sudo openssl genrsa 4096 > ca-key.pem
sudo openssl req -new -x509 -nodes -days 36500 -key ca-key.pem -out cacert.pem
sudo openssl req -newkey rsa:4096 -days 36500 -nodes -keyout server-key.pem -out server-req.pem
sudo openssl rsa -in server-key.pem -out server-key.pem
sudo openssl x509 -req -in server-req.pem -days 36500 -CA cacert.pem …

我想配置 Maven 以使用这些依赖项运行 Junit 5 测试：

        <dependency>
            <groupId>org.junit.jupiter</groupId>
            <artifactId>junit-jupiter-api</artifactId>

        </dependency>
        <dependency>

            <version>3.3.3</version>
            <scope>test</scope>
        </dependency>

但我得到了例外：

你知道我该如何解决这个问题吗？
