优化这段代码 if (CbmcDocTypeEnum.CREDIT.getName().equals(docType)) { docType = CbmcDocTypeEnum.CREDIT.getCode(); } else if (CertDocTypeEnum.CREDIT.getName().equals(docType)) { docType = CertDocTypeEnum.CREDIT.getCode(); } else if (CertDocTypeEnum.LABOURER_RIGHTS.getName().equals(docType)) { docType = CertDocTypeEnum.LABOURER_RIGHTS.getCode(); } else { fail += 1; result.append("第").append(i).append("条,产品类型格式有误!"); continue; }

你可以优化这段代码如下：

String code = null;
if (CbmcDocTypeEnum.CREDIT.getName().equals(docType)) {
    code = CbmcDocTypeEnum.CREDIT.getCode();
} else if (CertDocTypeEnum.CREDIT.getName().equals(docType)) {
    code = CertDocTypeEnum.CREDIT.getCode();
} else if (CertDocTypeEnum.LABOURER_RIGHTS.getName().equals(docType)) {
    code = CertDocTypeEnum.LABOURER_RIGHTS.getCode();
} else {
    fail += 1;
    result.append("第").append(i).append("条,产品类型格式有误!");
    continue;
}
docType = code;

在这个优化后的代码中，我将重复的赋值语句提取出来，避免了重复的代码。使用一个局部变量`code`来存储根据`docType`获取到的对应的`code`值。最后再将`code`赋值给`docType`。这样可以使代码更简洁可读。
