Java操作文件路径正反斜杠问题解决

@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 "获取成功";
    }
}

@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 "获取成功";
    }
}

@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 "获取成功";
    }
}
