From af0e0a110e7187bf008655f7510199a0c0b25ec4 Mon Sep 17 00:00:00 2001 From: Nymph2333 <498092988@qq.com> Date: 星期一, 10 四月 2023 14:27:40 +0800 Subject: [PATCH] newInstance() 已弃用,使用clazz.getDeclaredConstructor().newInstance() This method propagates any exception thrown by the nullary constructor, including a checked exception. Use of this method effectively bypasses the compile-time exception checking that would otherwise be performed by the compiler. The Constructor.newInstance method avoids this problem by wrapping any exception thrown by the constructor in a (checked) InvocationTargetException. The call clazz.newInstance() can be replaced by clazz.getDeclaredConstructor().newInstance() The latter sequence of calls is inferred to be able to throw the additional exception types InvocationTargetException and NoSuchMethodException. Both of these exception types are subclasses of ReflectiveOperationException. --- ruoyi-common/src/main/java/com/ruoyi/common/utils/file/FileUploadUtils.java | 53 +++++++++++++++++++++++++++-------------------------- 1 files changed, 27 insertions(+), 26 deletions(-) diff --git a/ruoyi-common/src/main/java/com/ruoyi/common/utils/file/FileUploadUtils.java b/ruoyi-common/src/main/java/com/ruoyi/common/utils/file/FileUploadUtils.java index 183f918..4652a29 100644 --- a/ruoyi-common/src/main/java/com/ruoyi/common/utils/file/FileUploadUtils.java +++ b/ruoyi-common/src/main/java/com/ruoyi/common/utils/file/FileUploadUtils.java @@ -2,6 +2,8 @@ import java.io.File; import java.io.IOException; +import java.nio.file.Paths; +import java.util.Objects; import org.apache.commons.io.FilenameUtils; import org.springframework.web.multipart.MultipartFile; import com.ruoyi.common.config.RuoYiConfig; @@ -11,11 +13,11 @@ import com.ruoyi.common.exception.file.InvalidExtensionException; import com.ruoyi.common.utils.DateUtils; import com.ruoyi.common.utils.StringUtils; -import com.ruoyi.common.utils.uuid.IdUtils; +import com.ruoyi.common.utils.uuid.Seq; /** * 文件上传工具类 - * + * * @author ruoyi */ public class FileUploadUtils @@ -89,7 +91,7 @@ * * @param baseDir 相对应用的基目录 * @param file 上传的文件 - * @param extension 上传文件类型 + * @param allowedExtension 上传文件类型 * @return 返回上传成功的文件名 * @throws FileSizeLimitExceededException 如果超出最大大小 * @throws FileNameLengthLimitExceededException 文件名太长 @@ -100,7 +102,7 @@ throws FileSizeLimitExceededException, IOException, FileNameLengthLimitExceededException, InvalidExtensionException { - int fileNamelength = file.getOriginalFilename().length(); + int fileNamelength = Objects.requireNonNull(file.getOriginalFilename()).length(); if (fileNamelength > FileUploadUtils.DEFAULT_FILE_NAME_LENGTH) { throw new FileNameLengthLimitExceededException(FileUploadUtils.DEFAULT_FILE_NAME_LENGTH); @@ -110,10 +112,9 @@ String fileName = extractFilename(file); - File desc = getAbsoluteFile(baseDir, fileName); - file.transferTo(desc); - String pathFileName = getPathFileName(baseDir, fileName); - return pathFileName; + String absPath = getAbsoluteFile(baseDir, fileName).getAbsolutePath(); + file.transferTo(Paths.get(absPath)); + return getPathFileName(baseDir, fileName); } /** @@ -121,33 +122,29 @@ */ public static final String extractFilename(MultipartFile file) { - String fileName = file.getOriginalFilename(); - String extension = getExtension(file); - fileName = DateUtils.datePath() + "/" + IdUtils.fastUUID() + "." + extension; - return fileName; + return StringUtils.format("{}/{}_{}.{}", DateUtils.datePath(), + FilenameUtils.getBaseName(file.getOriginalFilename()), Seq.getId(Seq.uploadSeqType), getExtension(file)); } - private static final File getAbsoluteFile(String uploadDir, String fileName) throws IOException + public static final File getAbsoluteFile(String uploadDir, String fileName) throws IOException { File desc = new File(uploadDir + File.separator + fileName); - if (!desc.getParentFile().exists()) - { - desc.getParentFile().mkdirs(); - } if (!desc.exists()) { - desc.createNewFile(); + if (!desc.getParentFile().exists()) + { + desc.getParentFile().mkdirs(); + } } return desc; } - private static final String getPathFileName(String uploadDir, String fileName) throws IOException + public static final String getPathFileName(String uploadDir, String fileName) throws IOException { int dirLastIndex = RuoYiConfig.getProfile().length() + 1; String currentDir = StringUtils.substring(uploadDir, dirLastIndex); - String pathFileName = Constants.RESOURCE_PREFIX + "/" + currentDir + "/" + fileName; - return pathFileName; + return Constants.RESOURCE_PREFIX + "/" + currentDir + "/" + fileName; } /** @@ -162,7 +159,7 @@ throws FileSizeLimitExceededException, InvalidExtensionException { long size = file.getSize(); - if (DEFAULT_MAX_SIZE != -1 && size > DEFAULT_MAX_SIZE) + if (size > DEFAULT_MAX_SIZE) { throw new FileSizeLimitExceededException(DEFAULT_MAX_SIZE / 1024 / 1024); } @@ -186,12 +183,16 @@ throw new InvalidExtensionException.InvalidMediaExtensionException(allowedExtension, extension, fileName); } + else if (allowedExtension == MimeTypeUtils.VIDEO_EXTENSION) + { + throw new InvalidExtensionException.InvalidVideoExtensionException(allowedExtension, extension, + fileName); + } else { throw new InvalidExtensionException(allowedExtension, extension, fileName); } } - } /** @@ -215,7 +216,7 @@ /** * 获取文件名的后缀 - * + * * @param file 表单文件 * @return 后缀名 */ @@ -224,8 +225,8 @@ String extension = FilenameUtils.getExtension(file.getOriginalFilename()); if (StringUtils.isEmpty(extension)) { - extension = MimeTypeUtils.getExtension(file.getContentType()); + extension = MimeTypeUtils.getExtension(Objects.requireNonNull(file.getContentType())); } return extension; } -} \ No newline at end of file +} -- Gitblit v1.9.2
