Wie k\u00f6nnen mit Java PDF Dokumente erzeugt werden?<\/p>\n

Das geht mit ein paar Zeilen Code und iText<\/a>. Die iText Lib l\u00e4\u00dft sich leicht integrieren. Hier mal ein Beispiel um ein paar Daten zu haben, nehmen wir mal einen Lebenskalender. Der ganze Code (nur eine Java Klasse) liegt auf Github<\/a> und kann von dort<\/a> geladen werden. <\/p>\n

Also mal ein neues Mavenprojekt anlegen und in der pom.xml<\/strong> die iText Abh\u00e4ngigkeit einf\u00fcgen:<\/p>\n

\t\r\n<dependency>\r\n  \t<groupId>com.lowagie<\/groupId>\r\n        <artifactId>itext<\/artifactId>\r\n        <version>4.2.0<\/version>\r\n<\/dependency>\r\n<\/pre>\n
Dann mal ein paar Zeilen Javacode f\u00fcr die PDF Erzeugung z.B. so:<\/p>\n
\r\n\r\nprivate static void printPdfDokument(List<String> kalender) throws DocumentException, FileNotFoundException {\r\n\r\n\t\tDocument document = new Document(PageSize.A4);\r\n\t\tPdfWriter.getInstance(document, new FileOutputStream(\"lebenskalender.pdf\"));\r\n\t\tdocument.open();\r\n\r\n\t\tFont f = new Font();\r\n\t\tf.setFamily(\"Courier\");\r\n\t\tf.setSize(10);\r\n\r\n\t\tfor (String woche : kalender) {\r\n\t\t\tdocument.add(new Paragraph(woche, f));\r\n\t\t}\r\n\t\tdocument.close();\r\n\t}\r\n\r\n<\/pre>\n
und schon k\u00f6nnen wir ein PDF Dokument erzeugen. Hier das Ergebnis lebenskalender.pdf<\/a>.<\/p>\n
Hier mal die Ausgabe auf System.out:<\/p>\n
