Question

我已根据GWT

创建了组件

组件状态

package com.game.quest.ui.gwt;

import com.vaadin.shared.AbstractComponentState;

import java.util.ArrayList;
import java.util.List;

public class LinePlotState extends AbstractComponentState {

    public List<DataSeries> series = new ArrayList<>();

    public static class DataSeries {
        public String label;
        public String color;
        public List<Float> data;
    }

}

组件连接器

package com.game.quest.ui.gwt;

import ca.nanometrics.gflot.client.DataPoint;
import ca.nanometrics.gflot.client.SeriesHandler;
import ca.nanometrics.gflot.client.SimplePlot;

import com.game.quest.ui.gwt.LinePlotState.DataSeries;
import com.google.gwt.core.client.GWT;
import com.google.gwt.user.client.ui.Widget;
import com.vaadin.client.communication.StateChangeEvent;
import com.vaadin.client.ui.AbstractComponentConnector;
import com.vaadin.shared.ui.Connect;

@Connect(LinePlot.class)
public class LinePlotConnector extends AbstractComponentConnector {

    @Override
    public LinePlotState getState() {
        return (LinePlotState) super.getState();
    }

    @Override
    public SimplePlot getWidget() {
        return (SimplePlot) super.getWidget();
    }

    @Override
    protected Widget createWidget() {
        return GWT.create(SimplePlot.class);
    }

    @Override
    public void onStateChanged(StateChangeEvent stateChangeEvent) {
        super.onStateChanged(stateChangeEvent);

        getWidget().getModel().clear();
        for (DataSeries ds : getState().series) {

            SeriesHandler s = getWidget().getModel().addSeries(ds.label, ds.color);
            for (int i = 0; i < ds.data.size(); i++) {
                s.add(new DataPoint(i, ds.data.get(i)));
            }
        }
        getWidget().redraw();
    }

}

组件

package com.game.quest.ui.gwt;

import com.game.quest.ui.gwt.LinePlotState.DataSeries;
import com.vaadin.ui.AbstractComponent;

import java.util.Arrays;


public class LinePlot extends AbstractComponent {

    public LinePlot() {

    }

    public LinePlotState getState() {
        return (LinePlotState) super.getState();
    }

    public void addSeries(String label, String color, Float[] fs) {
        DataSeries ds = new DataSeries();
        ds.label = label;
        ds.color = color;
        ds.data = Arrays.asList(fs);
        getState().series.add(ds);
    }
}

我创建了widgetset.gwt.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE module PUBLIC "-//Vaadin//DTD Vaadin 7//EN" "https://raw.github.com/vaadin/gwt/master/distro-source/core/src/gwt-module.dtd">
<module>
    <inherits name="com.vaadin.terminal.gwt.DefaultWidgetSet" />
    <inherits name="ca.nanometrics.gflot.GFlot" />
</module>

我将此文件放在项目的resources文件夹中。我使用gradle-vaadin-plugin进行编译

我的build.gradle看起来像这样

apply plugin: 'com.bmuschko.tomcat'
apply plugin: 'java'
apply from: 'http://plugins.jasoft.fi/vaadin-groovy.plugin'

repositories {
    maven { url mavenRepoUrl }
    maven { url vaadinAddonsRepoUrl }
}

buildscript {
    repositories {
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath "com.bmuschko:gradle-tomcat-plugin:${gradleTomcatPlugin}"
    }
}

allprojects {
    group='com.game.quest'
}

dependencies {

    compile "org.springframework:spring-core:${springMvcVersion}"
    compile "org.springframework:spring-web:${springMvcVersion}"
    compile "org.springframework:spring-webmvc:${springMvcVersion}"
    compile "com.vaadin:vaadin-client:${vaadinVersion}"
    compile "com.vaadin:vaadin-themes:${vaadinVersion}"
    compile "com.vaadin:vaadin-server:${vaadinVersion}"
    compile "com.vaadin:vaadin-client-compiled:${vaadinVersion}"
    compile "ru.xpoft.vaadin:spring-vaadin-integration:${vaadinSpringIntegrationAddonVersion}"
    compile "org.hibernate:hibernate-validator:4.2.0.Final"

    def tomcatVersion = '7.0.59'
    tomcat "org.apache.tomcat.embed:tomcat-embed-core:${tomcatVersion}",
           "org.apache.tomcat.embed:tomcat-embed-logging-juli:${tomcatVersion}",
           "org.apache.tomcat.embed:tomcat-embed-jasper:${tomcatVersion}"

   compile "com.googlecode.gflot:gflot:${gFlotVersion}"
}

vaadin {
    version vaadinVersion
    widgetset 'Widgetset'
}

[tomcatRun, tomcatRunWar]*.configure {
    httpPort = 9080
    stopPort = 9081
}

但是当我尝试编译它时，我有这个错误

我使用vaadinVersion=7.5.0。

问题是什么？据我所知，它是GWT的一部分？

Answer 1

我遇到了同样的问题并通过增加gwt版本来解决它。

<dependency>
    <groupId>com.google.gwt</groupId>
    <artifactId>gwt-user</artifactId>
    <version>2.7.0</version>
</dependency>
