java - 如何解决shiro的重复提交问题？

Question

在 Spring ，我做了一个 HandlerInterceptor 来解决请求的重复提交，当我尝试在 Spring 中集成 shiro 时，我发现了一个问题，那就是如果我使用匿名过滤器进行重复提交(例如/登录)，代码运行良好，但是如果我使用自定义过滤器来处理请求，则请求始终待处理...

处理程序拦截器:

public class RepeatSubmitHandler implements HandlerInterceptor {

@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
    log.info("preHandler was working....");
  }

@Override
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
    log.info("afterCompletion was working...");
  }
}  

shiro配置:

@Bean("shiroFilter")
public ShiroFilterFactoryBean shirFilter(SecurityManager securityManager) {
    ShiroFilterFactoryBean shiroFilter = new ShiroFilterFactoryBean();
    shiroFilter.setSecurityManager(securityManager);

    Map<String, Filter> filters =  shiroFilter.getFilters();
    filters.put("oauth2", new OAuth2Filter());
    shiroFilter.setFilters(filters);

    Map<String, String> filterMap = new LinkedHashMap<>(); 
    //anon filter, shiro default filter
    filterMap.put("/api/sys/login", "anon"); 
    //custom filter
    filterMap.put("/**", "oauth2"); 
    shiroFilter.setFilterChainDefinitionMap(filterMap);

    return shiroFilter;
}

Controller :

@PostMapping("/login")
public RestResponse login(@RequestBody SysLoginVo loginForm) {
    log.info("login was working...");
}

@GetMapping("/nav")
public RestResponse nav() throws InterruptedException {
    log.info("nav was working...");
}

带有匿名过滤器的控制台来处理重复提交:这是我的目的

    preHandler was working....
    login was working...

    preHandler was working....
    preHandler was working....
    preHandler was working....

    afterCompletion was working...

带有自定义过滤器的控制台来处理重复提交:

    preHandler was working....
    nav was working...
    afterCompletion was working...

    preHandler was working....
    nav was working...
    afterCompletion was working...

好吧，是我的错，原因与shiro无关，仅针对get请求，对于发送get请求，请求将处于pending状态
