通过在Eclipse / STS中使用“Spring Stater Project”,我能够快速启动并运行Vaadin项目.我想通过Vaadin-Addon将图表添加到项目中.我谷歌搜索试图找到如何正确添加和使用Vaadin Chart插件到项目.但我很困惑,因为有很多“指南/教程”,但很多不是春季启动或他们已过时或部分.
所以我正在寻找Vaadin-SpringBoot-VaadinChart-AddOn的完整指南/教程.
这是我到目前为止：
—- Pom文件—-
—- Java代码—-
public class BasicBarChart extends AbstractVaadinChartExample {
@Override
public String getDescription() {
return "Basic bar";
}
@Override
protected Component getChart() {
Chart chart = new Chart(ChartType.BAR);
Configuration conf = chart.getConfiguration();
conf.setTitle("Historic World Population by Region");
conf.setSubTitle("Source: Wikipedia.org");
XAxis x = new XAxis();
x.setCategories("Africa","America","Asia","Europe","Oceania");
x.setTitle((String) null);
conf.addxAxis(x);
YAxis y = new YAxis();
y.setMin(0);
Title title = new Title("Population (millions)");
title.setVerticalAlign(VerticalAlign.HIGH);
y.setTitle(title);
conf.addyAxis(y);
Tooltip tooltip = new Tooltip();
tooltip.setFormatter("this.series.name +': '+ this.y +' millions'");
conf.setTooltip(tooltip);
PlotOptionsBar plot = new PlotOptionsBar();
plot.setDataLabels(new Labels(true));
conf.setPlotOptions(plot);
Legend legend = new Legend();
legend.setLayout(LayoutDirection.VERTICAL);
legend.setHorizontalAlign(HorizontalAlign.RIGHT);
legend.setVerticalAlign(VerticalAlign.TOP);
legend.setX(-100);
legend.setY(100);
legend.setFloating(true);
legend.setBorderWidth(1);
legend.setBackgroundColor("#FFFFFF");
legend.setShadow(true);
conf.setLegend(legend);
conf.disableCredits();
List series = new ArrayList();
series.add(new ListSeries("Year 1800",107,31,635,203,2));
series.add(new ListSeries("Year 1900",133,156,947,408,6));
series.add(new ListSeries("Year 2008",973,914,4054,732,34));
conf.setSeries(series);
chart.drawChart(conf);
return chart;
}
}
@SpringUI
@VaadinServletConfiguration(productionMode = false,ui = MyVaadinUI.class)
public class MyVaadinUI extends UI {
@Override
protected void init(VaadinRequest vaadinRequest) {
setContent(new BasicBarChart());
}
}
我已经创建了30天的AGPL许可证密钥
有些网站说我需要一个gwt.xml文件,或者这可以通过注释完成
有些网站说我需要“重新编译你的widgetset”,这意味着我需要在我的pom文件中添加一些插件.
其他网站说我需要一个web.xml,但只需运行spring-boot-vaadin Vaadin应用程序.
当我运行代码时,我得到：
Widgetset ‘com.vaadin.DefaultWidgetSet’ does not contain implementation for com.vaadin.addon.charts.Chart. Check its component connector’s @Connect mapping,widgetsets GWT module description file and re-compile your widgetset. In case you have downloaded a vaadin add-on package,you might want to refer to add-on instructions.
这些是使用TouchKit附加组件的示例说明,但过程基本相同：
>使用cdn.virit.in的简单选项：
>将插件添加到pom.xml
>将生成的servlet过滤器添加到配置https://github.com/mstahv/vaadin-spring-touchkit/blob/master/src/main/java/org/vaadin/tkspring/Application.java#L20-L25
>标准解决方案：
>添加vaadin-maven-plugn to pom.xml
>将@Widgetset注释添加到UI class
