Question

基本上我正在尝试使用JavaFX中的某些字段填充表。我能够填充具有String数据类型的字段，但无法用整数数据类型填充字段。任何人都可以抛出为什么整数字段没有填充？下面是我创建的文件的代码。应该对代码进行哪些更改？

FXML文件：

<?import javafx.scene.control.cell.PropertyValueFactory?>

<?import javafx.scene.text.Font?>

数据文件（Beans文件）DataSource

package application;

public class DataSource {

    private final SimpleStringProperty projectName = new SimpleStringProperty("");
    private final SimpleStringProperty environment = new SimpleStringProperty("");

    private final SimpleStringProperty defaultValue = new SimpleStringProperty("");

    public DataSource(){
        this(1,"","","","");
    }

    public DataSource(Integer serial, String projectName,String envName, String serverURL, String defaultValue){
        serial = 0; serial++;
        setSerial(serial);
        setEnvironment(envName);
        setProjectName(projectName);
        setServerURL(serverURL);
        setDefaultValue(defaultValue);
    }

    public int getSerial(){
        return serialNo.get();
    }

    public void setSerial(int serialNum){
        serialNo.set(serialNum);
    }

    public String getProjectName(){
        return projectName.get();
    }

    public void setProjectName(String prjName){
        projectName.set(prjName);
    }

    public String getEnvironment(){
        return environment.get();
    }

    public void setEnvironment(String envName){
        environment.set(envName);
    }

    public String getServerURL(){
        return serverURL.get();
    }

    public void setServerURL(String serverUrl){
        serverURL.set(serverUrl);
    }

    public String getDefaultValue(){
        return defaultValue.get();
    }

    public void setDefaultValue(String defaultInd){
        defaultValue.set(defaultInd);
    }
}

Answer 1

终于得到了解决方案！其实我的吸气剂和放大器序列号的setter方法与我在DataSource.java文件中声明的名称不匹配。刚刚在DataSource.java文件中更改了以下内容：

public int getSerialNo(){
        return serialNo.get();
    }

    public void setSerialNo(int serialNum){
        serialNo.set(serialNum);
    }

对于getter和amp;而言，从串口更改为SerialNo二传法。最后它工作了!!!
