orderDO.setOrderStatusCode(OrderStatusEnum.WAIT_ISSUED.getCode()) if(!orderDO.getOrderStatusCode().equals(OrderStatusEnum.SAVED.getCode()) | !orderDO.getOrderStatusCode().equals(OrderStatusEnum.WAIT_APPOINTMENT.getCode()) | !orderDO.getOrderStatusCode().equals(OrderStatusEnum.WAIT_ISSUED.getCode()) | !orderDO.getOrderStatusCode().equals(OrderStatusEnum.INTERCEPTED.getCode())){ throw new BusinessException("该订单状态无法作废"); }

这段Java代码的意思是,如果订单的状态不是已保存、待预约、待发货或被拦截状态之一,那么就将其状态设置为待发货,并继续执行后续代码。如果订单的状态是上述四个状态之一,那么就会抛出一个自定义的业务异常,提示该订单状态无法作废。其中,OrderStatusEnum是一个枚举类型,它定义了不同的订单状态码。BusinessException是一个自定义的异常类,用于表示业务异常情况。

perl cpan 安装包 Issued certificate has expired.
如果在使用 `cpan` 安装 Perl 模块时出现 "Issued certificate has expired" 错误,可能是因为你的系统中的 CA 证书已过期或需要更新。为了解决这个问题,你可以按照以下步骤操作:
1. 更新 CA 证书
在终端中执行以下命令,更新系统中的 CA 证书:
```
sudo yum update ca-certificates
```
2. 设置 CPAN 配置
在终端中执行以下命令,设置 CPAN 配置:
```
perl -MCPAN -e shell
```
进入 CPAN shell 后,执行以下命令设置 `cpan` 使用的协议:
```
o conf urllist http://www.cpan.org/
```
然后执行以下命令保存配置并退出 CPAN shell:
```
o conf commit
exit
```
3. 重新安装模块
重新执行 `cpan` 安装模块的命令,例如:
```
sudo cpan install Module::Name
```
如果上述步骤仍然无法解决问题,可以尝试手动下载模块源代码并进行安装。
with warnings.catch_warnings():
As an AI language model, I cannot provide complete context without more information about the code. But, in general, the `warnings.catch_warnings()` is a context manager that can be used to temporarily suppress warnings issued by the Python interpreter.
For example, if you have a piece of code that generates a warning, but you know that it is harmless and you don't want to see it every time you run your program, you can use `warnings.catch_warnings()` to temporarily suppress the warning:
```
import warnings
with warnings.catch_warnings():
warnings.simplefilter("ignore")
# code that generates a warning
```
In this example, `warnings.simplefilter("ignore")` is used to set the warning filter to "ignore", which means that all warnings will be suppressed. The code that generates a warning is then executed inside the `with` block, and any warnings that it generates will be ignored. Once the block is exited, the warning filter is restored to its previous state.
