java - Birt报表-IReportEngineFactory为空

Question

我在Eclipse上使用BIRT没问题，但是我的新公司使用IntelliJ IDEA。

在Gradle中使用项目

compile files('src/main/resources/lib/flute-1.3.jar') 
compile(group: 'org.eclipse.birt.runtime', name: 'org.eclipse.birt.runtime', version: '4.4.2') { exclude(group: 'org.milyn', module: 'flute') }

通过main方法运行本地时，我没有问题。但是通过编译项目后

shadowJar { 
      classifier = null 
      version = version 
      manifest { 
             attributes 'Main-Class': 'io.vertx.core.Starter'
             attributes 'Main-Verticle': 'other.app.App' 
      } 
      mergeServiceFiles { 
             include 'META-INF/services/io.vertx.core.spi.VerticleFactory' 
      } 
}

我没有

IReportEngineFactory factory = (IReportEngineFactory) Platform .createFactoryObject(IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY);

试图解决这个问题一个星期，我仍然找不到解决方案。有人有什么建议吗？阅读的烦恼。

我的代码就可以了:

 @Override
    public void generateUserInformationPdf(JsonObject payload) {

        try {

            LOGGER.info("Starting render User Information");

            /* begin get parameters */

            CommonRequest request = gson.fromJson(payload, CommonRequest.class);

            UserPdfPrint userInformation = gson.fromJson(request.getData(), UserPdfPrint.class);

            String p_username = userInformation.getUsername();
            String p_customername = userInformation.getCustomerName();
            String p_dob = userInformation.getDob();
            String p_license = userInformation.getLicense();
            String p_licensedate = userInformation.getLicenseDate();
            String p_licenseplace = userInformation.getLicensePlace();
            String p_sex = userInformation.getSex();
            String p_customerphone = userInformation.getCustomerPhone();
            String p_email = userInformation.getEmail();
            int p_licensetype = userInformation.getLicenseType();


            /* end get parameters section */

            /* load report design */
            String reportName = config.getReportUserInformation();
            IReportEngine engine = null;
            IReportRunnable design = null;

            URL url = null;

            engineConfig.setLogConfig(null, Level.FINE);
            engineConfig.setFontConfig(url);

            Platform.startup(engineConfig);

            IReportEngineFactory factory = (IReportEngineFactory) Platform
                    .createFactoryObject(IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY);

            engine = factory.createReportEngine(engineConfig);

            design = engine
                    .openReportDesign(config.getReportTemplatePath()
                            + "/" + reportName); // report

            /* end load report design */

            /* begin render report */
            IRunAndRenderTask task = null;
            PDFRenderOption renderContext = null;
            HashMap contextMap = null;

            task = engine.createRunAndRenderTask(design);
            renderContext = new PDFRenderOption();
            contextMap = new HashMap();
            contextMap.put(EngineConstants.APPCONTEXT_HTML_RENDER_CONTEXT,
                    renderContext);
            contextMap.put("OdaJDBCDriverPassInConnection", config.getDbConnection());
            task.setAppContext(contextMap);

            task.setParameterValue("p_username", p_username);

            task.validateParameters();

            String random = Generator.generateRandomNumber();

            String today = DateTimes.getCurrentDate().toString();

我也遇到过同样的问题。更新构建gradle并添加

"flute-1.3.jar" & "org.eclipse.orbit.mongodb-2.10.1.v20130422-1135.jar"

在 lib 文件夹中。

//Start of birt
    compile(group: 'org.eclipse.birt.runtime', name: 'org.eclipse.birt.runtime', version: '4.4.2') {
        exclude(group: 'org.milyn', module: 'flute')
        exclude(group: 'org.eclipse.birt.runtime', module: 'org.eclipse.orbit.mongodb')
    }
    //End of birt
