数据填充器

提示

• 如果觉得内置的id、创建时间和更新时间自动生成规则，不符合业务要求，可通过填充器覆盖

1、自定义填充器，并继承DataFillHandler

public class CustomDataFillHandler implements DataFillHandler {

    @Override
    public void idFill(Object object) {
        RootEntity entity = (RootEntity) object;
        if (ObjectUtil.isNotNull(entity)) {
            if (Objects.isNull(entity.getId())) {
                entity.setId(IdUtils.nextId());
            }
        }
    }

    @Override
    public void insertFill(Object object) {
        RootEntity entity = (RootEntity) object;
        if (ObjectUtil.isNotNull(entity)) {
            entity.setCreateTime(ObjectUtil.isNotNull(entity.getCreateTime()) ? entity.getCreateTime() : new Date());
            entity.setUpdateTime(ObjectUtil.isNotNull(entity.getUpdateTime()) ? entity.getUpdateTime() : new Date());

            PermissionHandler permissionHandler = FlowEngine.permissionHandler();
            String handler = null;
            if (permissionHandler != null) {
                handler = permissionHandler.getHandler();
            }
            entity.setCreateBy(StringUtils.isNotEmpty(handler) ? handler : entity.getCreateBy());
            entity.setUpdateBy(StringUtils.isNotEmpty(handler) ? handler : entity.getUpdateBy());
        }
    }

    @Override
    public void updateFill(Object object) {
        RootEntity entity = (RootEntity) object;
        if (ObjectUtil.isNotNull(entity)) {
            entity.setUpdateTime(ObjectUtil.isNotNull(entity.getUpdateTime()) ? entity.getUpdateTime() : new Date());

            PermissionHandler permissionHandler = FlowEngine.permissionHandler();
            String handler = null;
            if (permissionHandler != null) {
                handler = permissionHandler.getHandler();
            }
            entity.setUpdateBy(StringUtils.isNotEmpty(handler) ? handler : entity.getUpdateBy());
        }
    }
}

2、注入bean

yaml

# warm-flow工作流配置
warm-flow:
  # 填充器，内部有默认实现，如果不满足实际业务，可通过此配置自定义实现
  data-fill-handler-path: com.ruoyi.system.handle.CustomDataFillHandler

@Bean

@Configuration
public class WarmFlowConfig {

    @Bean
    public DataFillHandler dataFillHandler() {
        return new CustomDataFillHandler();
    }
}

@Component

@Component
public class CustomDataFillHandler implements DataFillHandler {

    ...实际代码
}
