我正在尝试运行我的程序,我总是得到这个例外:

Caused by: org.springframework.beans.factory.BeanCreationException: Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath.

我通过gradle导入所有依赖项:

buildscript {
repositories {
    mavenCentral()
}
dependencies {
    classpath("org.springframework.boot:spring-boot-gradle-plugin:1.2.7.RELEASE")
}
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot'

jar {
baseName = 'flatify-backend-service'
version =  '0.1.0'
}

repositories …

我是iText的新手,我正在尝试构建一个表.但由于某些原因table.getDefaultCell().setBorder(PdfPCell.NO_BORDER)没有效果,我的桌子还有边框.

这是我的代码:

PdfPTable table = new PdfPTable(new float[] { 1, 1, 1, 1, 1 });
table.getDefaultCell().setBorder(PdfPCell.NO_BORDER);
Font tfont = new Font(Font.FontFamily.UNDEFINED, 10, Font.BOLD);
table.setWidthPercentage(100);
PdfPCell cell;
cell = new PdfPCell(new Phrase("Menge", tfont));
table.addCell(cell);
cell = new PdfPCell(new Phrase("Beschreibung", tfont));
table.addCell(cell);
cell = new PdfPCell(new Phrase("Einzelpreis", tfont));
table.addCell(cell);
cell = new PdfPCell(new Phrase("Gesamtpreis", tfont));
table.addCell(cell);
cell = new PdfPCell(new Phrase("MwSt", tfont));
table.addCell(cell);
document.add(table);

你知道我做错了什么吗？
