1.Controller逻辑

    @GetMapping("/user/delete/{id}")
    public String deleteUser(@PathVariable("id") Long id,
                             @RequestParam(value = "pn",defaultValue = "1") Integer pn,
                             RedirectAttributes ra){
        userService.removeById(id);

        // 重定向添加参数
        ra.addAttribute("pn",pn);
        return "redirect:/dynamic_table";
    }

2.删除按钮

<td><a th:href="@{/user/delete/{id}(id = ${user.id},pn=${page.current})}" class="btn btn-danger" type="button">Delete</a></td>

重定向添加参数

ra.addAttribute("pn",pn);
return "redirect:/dynamic_table";
