最近在實(shí)現(xiàn)文件上傳時(shí),windows與linux系統(tǒng)出現(xiàn)的問(wèn)題,兩個(gè)系統(tǒng)中操作文件使用"\","/"導(dǎo)致IOException,本文主要介紹了Java操作文件路徑正反斜杠問(wèn)題解決,感興趣的可以了解一下啊

一. 起因

問(wèn)題來(lái)源:最近在實(shí)現(xiàn)文件上傳時(shí),windows與linux系統(tǒng)出現(xiàn)的問(wèn)題,兩個(gè)系統(tǒng)中操作文件使用"\","/"導(dǎo)致IOException

二. 測(cè)試正反斜桿

2.1 \

@Controller
@RequestMapping("/test")
public class Test {

    @RequestMapping("/file")
    @ResponseBody
    public Object readFile(HttpServletResponse response) throws IOException {
        BufferedImage banner = ImageIO.read(new File("F:\\Img\\ghost_K\\bj3.jpeg"));
        ImageIO.write(banner, "jpeg", response.getOutputStream());
        return "獲取成功";
    }
}

運(yùn)行結(jié)果

2.2 /

@Controller
@RequestMapping("/test")
public class Test {

    @RequestMapping("/file2")
    @ResponseBody
    public Object readFile2(HttpServletResponse response) throws IOException {
        BufferedImage banner = ImageIO.read(new File("F:/Img/ghost_K/bj3.jpeg"));
        ImageIO.write(banner, "jpeg", response.getOutputStream());
        return "獲取成功";
    }
}

運(yùn)行結(jié)果

2.3 混用

@Controller
@RequestMapping("/test")
public class Test {

     @RequestMapping("/file1")
    @ResponseBody
    public Object readFile1(HttpServletResponse response) throws IOException {
        BufferedImage banner = ImageIO.read(new File("F:\\Img/ghost_K\\bj3.jpeg"));
        ImageIO.write(banner, "jpeg", response.getOutputStream());
        return "獲取成功";
    }
}

運(yùn)行結(jié)果
