SpringBoot Controller 跳转到Controller 实现重定向,并且携带参数

SpringBoot中Controller之间跳转并携带参数,下面是具体步骤

1. 使用Controller注解

@Controller

---

2. 添加thymeleaf依赖

       
            org.springframework.boot
            spring-boot-starter-thymeleaf
        

3. 添加配置

spring:
  thymeleaf:
    prefix: classpath:/templates/
    mode: html5
    encoding: utf-8
    suffix: .html

4. 在resources下的templates页面下放置你要跳转的html即可

下面是请求方法:

 @PostMapping("/user/query")
    public String query(@RequestBody User user, RedirectAttributes attr, HttpServletResponse response) throws IOException {
        if (null == user) {
            response.setCharacterEncoding("UTF-8");
            response.getWriter().write(JsonUtils.toJson("错误"));
            return null;
        }
 
        if (merchantOrderVO.getHtml() == 1) {
             attr.addFlashAttribute("user",user);
             return "redirect:/user/queryHtml";
         }

  
        return "user.html";

    }

    /**
     * 返回网页模板
     *
     * @param
     * @return
     */
    @RequestMapping("/user/queryHtml")
    public String createOrderHtml(@ModelAttribute("user") User user) {

    if (null == user) {
            return "404.html";
        }
         return "user.html";
    }
