内部调用其他服务抛出的异常处理

try {
            requisition_no = this.testDocumentId(info);// 获取申请单号
        } catch (java.lang.reflect.InvocationTargetException targetE) {
            throw new DWBusinessException("自动生成单号失败："+targetE.getTargetException().getMessage());
        } catch (Exception e){
            throw new DWBusinessException("自动生成单号失败！");
        }
