#### 需要的依赖包 ####

<dependency>
                <groupId>org.activiti</groupId>
                <artifactId>activiti-image-generator</artifactId>
                <version>7.0.0.GA</version>
            </dependency>
    
            <dependency>
                <groupId>dom4j</groupId>
                <artifactId>dom4j</artifactId>
                <version>1.1</version>
            </dependency>

#### 生成SVG图片 ####

我们可以将工作流的图生成SVG图片，这样当我们整合activiti到项目中的时候就可以方便查看了

@Test
    public void testGenerateSVG() throws IOException {
        
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        RepositoryService repositoryService = processEngine.getRepositoryService();
    
        BpmnModel bpmnModel = repositoryService.getBpmnModel("test:1:2503");
    
        ProcessDiagramGenerator generator = new DefaultProcessDiagramGenerator();
    
        //InputStream inputStream = generator.generateDiagram(bpmnModel, lastTask, Collections.emptyList(), "宋体", "宋体", "宋体", true, "test");
        InputStream inputStream = generator.generateDiagram(bpmnModel, "endEvent", "宋体", "宋体");
    
        String imageName = "image-" + Instant.now().getEpochSecond() + ".svg";
        FileUtils.copyInputStreamToFile(inputStream, new File("processes/" + imageName));
    
    }

生成的流程图如下：我这里是IDEA打开的svg所以比较丑一点。。。。哈哈哈哈，实际上是个透明图的
