今日份代码:

Spring

private static final String UPLOAD_TEMP_FILE_NAME = "测试商品数据.xlsx";

  /**
* 获取临时文件路径
* @return
*/
private String getFilePath(){
String path = 当前类.class.getResource("/").getPath()+UPLOAD_TEMP_FILE_NAME;
return path;
}

Spring Boot:

    //第一种
File path = new File(ResourceUtils.getURL("classpath:").getPath());
if(!path.exists()) path = new File("");
System.out.println(path.getAbsolutePath());
//第二种
System.out.println(System.getProperty("user.dir"));
//第三种
String path1 = ClassUtils.getDefaultClassLoader().getResource("").getPath();
System.out.println(URLDecoder.decode(path1, "utf-8"));
//第四种
String path2 = ResourceUtils.getURL("classpath:").getPath();
System.out.println(path2);
//第五种 spring boot打jar包,建议使用第五种
ApplicationHome h = new ApplicationHome(getClass());
File jarF = h.getSource();
System.out.println(jarF.getParentFile().toString());
//第六种 spring boot打jar包或者不打包,都可以使用的,建议区分系统以完善路径 本种也建议使用
Properties properties = System.getProperties();
System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>系统:" + properties.getProperty("os.name"));
System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>根路径" + properties.getProperty("user.dir")); String path = properties.getProperty("user.dir");
if (properties.getProperty("os.name").toLowerCase().contains("win")) {
path += "\\";
}else {
path += "/";
}

使用第五种示例如下:

private static final String UPLOAD_TEMP_FILE_NAME = "测试商品数据.xlsx";

  /**
* 获取临时文件路径
* @return
*/
private String getFilePath(){
ApplicationHome h = new ApplicationHome(getClass());
File jarF = h.getSource();
String path = jarF.getParentFile().toString();
int i = path.lastIndexOf("/");
if (i > 0) {
path = path.substring(0,i+1);
}
path += UPLOAD_TEMP_FILE_NAME;
return path;
}

使用第六种示例如下:

windows本机未打包运行结果:
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>系统:Windows 10
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>根路径E:\document\ideaProject\p-job Linux打jar包运行结果:
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>系统:Linux
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>根路径/data/web/domains/p-job.com/server8097
private static final String UPLOAD_TEMP_FILE_NAME = "测试商品数据.xlsx";

  /**
* 获取临时文件路径
* @return
*/
private String getFilePath(){
Properties properties = System.getProperties();
System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>系统:" + properties.getProperty("os.name"));
System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>根路径" + properties.getProperty("user.dir")); String path = properties.getProperty("user.dir");
if (properties.getProperty("os.name").toLowerCase().contains("win")) {
path += "\\";
}else {
path += "/";
}
path += UPLOAD_TEMP_FILE_NAME;
return path;
}
