因为这个项目license问题无法开源，更多技术支持与服务请加入我的知识星球。

1、项目中途不知道什么原因，就出现下面情况

具体如下：

2024-07-15 15:08:15.767 [main] [34mINFO [0;39m [36mliquibase.changelog:30[0;39m - Reading from `jeecg-test`.FLW_EV_DATABASECHANGELOG

2、3、到上面就停顿了，过上10多分钟再继续下去了，看下面的图片

3、应该是下面这个接口有问题，看来看去就是ProcessModel processModel这个有问题了，其它应该也没有什么了，但没有任何报错，比较奇怪

@ApiOperation(value = "保存钉钉流程设计器内的xml文件和json")
    @PostMapping("/saveDd")
    public Result saveDd(@RequestBody ProcessModel processModel) {
    	return Result.OK("OK");
    	//return flowDefinitionService.saveDdModel(processModel);
    }

4、ProcessModel processModel换掉就正常了，那说明这个类初始化还是有点问题啊，但看着下面的代码也没有什么问题啊

@Data
public class ProcessModel{
    @JsonSerialize(using = ToStringSerializer.class)
    private String id;
    private String code;
    private String name;
    private Node process;
    @JsonSerialize(using = ToStringSerializer.class)
    private String flowJson;
    private String category;
    private String appType;
    private Integer version;
    private Integer sort;
    @JsonSerialize(using = ToStringSerializer.class)
    private String groupId;
    private String remark;

    public BpmnModel toBpmnModel() {
        BpmnModel bpmnModel = new BpmnModel();
        // 命名空间
        bpmnModel.setTargetNamespace(ProcessConstants.NAMASPASE);
        // 创建一个流程
        Process process = new Process();
        // 设置流程的id
        process.setId(this.getCode());
        // 设置流程的name
        process.setName(this.getName());
        // 设置流程的文档
        process.setDocumentation(this.getRemark());
        // 递归构建所有节点
        Node node = this.getProcess();
        List<FlowElement> flowElementList = node.convert();
        for (FlowElement flowElement : flowElementList) {
            process.addFlowElement(flowElement);
        }
        // 设置流程
        bpmnModel.addProcess(process);
        // 自动布局
        new BpmnAutoLayout(bpmnModel).execute();
        return bpmnModel;
    }

}

5、但后来发现跟这个可能跟@ApiOperation之间有冲突了

发现去掉@ApiOperation(value = "保存钉钉流程设计器内的xml文件和json") 后就正常了，晕倒。

6、另外有时候还会出现这样情况，下面这种情况一般重新全编译就可以了。
