Activiti生成流程图异常解决(java.awt.image.RasterFromatException)
Activiti生成流程图代码：
?
ProcessDefinitionEntity p = (ProcessDefinitionEntity)repositoryService.createProcessDefinitionQuery().processDefinitionId("test:2:13708").singleResult();InputStream in = ProcessDiagramGenerator.generateDiagram(p,"png", Arrays.asList("usertask1"));?
?抛出异常：
? ?java.awt.image.RasterFormatException: (x + width) is outside raster

解决方法： 将RepositoryService 转换为?RepositoryServiceImpl 对象 通过该对象的?getDeployedProcessDefinition方法来获取流程定义
?
?
RepositoryServiceImpl imp = (RepositoryServiceImpl)repositoryService;ProcessDefinitionEntity entity2 = (ProcessDefinitionEntity)imp.getDeployedProcessDefinition("test:2:13708");InputStream in = ProcessDiagramGenerator.generateDiagram(p,"png", Arrays.asList("usertask1"));??
