LocalDateタイプの書式付きテキストフィールドの使用方法

Question

私はスイングを使用していて、データベースから1つの日付を変換しようとしていますが、マスターディテールを使用してフォームを生成しました！ 私はDate型とそれを使用していた場合、それが正常に動作しますが、私はLOCALDATEで使用しようとすると、それは私がこの例外を取得：

Exception in thread "AWT-EventQueue-0" org.jdesktop.beansbinding.PropertyResolutionException: Exception invoking method public void javax.swing.JFormattedTextField.setValue(java.lang.Object) on javax.swing.JFormattedTextField[,71,210,541x28,layout=javax.swing.plaf.basic.BasicTextUI$UpdateHandler,alignmentX=0.0,alignmentY=0.0,border=javax.swing.plaf.synth.SynthBorder@64d52f45,flags=288,maximumSize=,minimumSize=,preferredSize=,caretColor=,disabledTextColor=DerivedColor(color=142,143,145 parent=nimbusDisabledText offsets=0.0,0.0,0.0,0 pColor=142,143,145,editable=true,margin=javax.swing.plaf.InsetsUIResource[top=0,left=0,bottom=0,right=0],selectedTextColor=DerivedColor(color=255,255,255 parent=nimbusSelectedText offsets=0.0,0.0,0.0,0 pColor=255,255,255,selectionColor=DerivedColor(color=57,105,138 parent=nimbusSelectionBackground offsets=0.0,0.0,0.0,0 pColor=57,105,138,columns=0,columnWidth=0,command=,horizontalAlignment=LEADING] 

は、これが私のフォームです：

パッケージbr.com.imprimindo .conteudo.itext;

package br.com.imprimindo.conteudo.itext; 

import java.awt.Component; 
import java.text.SimpleDateFormat; 
import java.time.LocalDate; 
import java.util.Date; 
import javax.swing.JTable; 
import javax.swing.table.DefaultTableCellRenderer; 


public class DateRender extends DefaultTableCellRenderer { 

    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd"); 

    public Component getTableCellRendererComponent(JTable table, Object value, 
      boolean isSelected, boolean hasFocus, int row, int column) { 

     super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column); 
     if (value instanceof LocalDate) { 
      this.setText(sdf.format((LocalDate) value)); 
     } 
     return this; 
    } 

} 

これは、それが正常に動作マスターブランチで github
でプロジェクトですが、問題は、それが「LOCALDATE」と呼ばれるブランチにあります：

Answer 1

あなたはので、このラインのこのエラーを取得しています

this.setText(sdf.format((LocalDate) value)); 

あなたはLocalDateと直接SimpleDateFormatを使用することはできません。 LocalDateをDateに変換してからSimpleDateFormatを変換したDateオブジェクトに変換する必要があります。ここで

はhere与え@Sotirios答えからコードスニペットです：

LocalDate localDate = ... ; 
Instant instant = localDate.atStartOfDay().atZone(ZoneId.systemDefault()).toInstant(); 
Date res = Date.from(instant); 

詳しい情報はこちらです：ユーザーとして http://blog.progs.be/542/date-to-java-time

Answer 2

user2004685あなたはLocalDateと直接SimpleDateFormatを使用することはできません、と述べました。最も簡単な解決策はjava.sql.Dateを通じてjava.util.DateにLocalDateを変換することです：

java.util.Date date = java.sql.Date.valueOf(localDate); 
this.setText(sdf.format(date));
