Login interceptor (interception of requests, different requests enter different login pages)

Login interceptor: ShiroInterceptorFilter . Inherited from FormAuthenticationFilter

Get the request path before being intercepted:

WebUtils.getSavedRequest(request);

String url = savedRequest.getRequestUrl();

public class ShiroInterceptorFilter extends FormAuthenticationFilter 
{ 
    //Default PC-side login request private String loginUrl;
     //Used to store the request path that needs to be intercepted
     static List<String> interceptorUrlList = new ArrayList<>();
     //Static code block, loading needs to be intercepted [In this example, the request path of the mobile terminal is stored]
    static{
    
        interceptorUrlList.add("/manage/index"); 
        interceptorUrlList.add("/system"); 
         ...... }
 
    //Interceptor The construction method   public ShiroInterceptorFilter() { 
    } 
    public ShiroInterceptorFilter(String loginUrl) { 
        this.loginUrl = loginUrl; 
    } 
    //Get/set method of parameters 
    @Override 
        return loginUrl;
    
   
   
  

 
    public String getLoginUrl() {
    } 

    @Override 
    public void setLoginUrl(String loginUrl) { 
        this.loginUrl = loginUrl; 
    } 


    //Overridden method of jumping to the login page 
    @Override   protected void redirectToLogin(ServletRequest request, ServletResponse response) throws IOException {
    
        //From the request header Get the current request path in 
        HttpServletRequest httpServletRequest = (HttpServletRequest) request; 
        String url = httpServletRequest.getServletPath(); 
        //Identification used to determine whether it needs to be intercepted. It does not need to be intercepted by default. 
        Boolean flag = false; 
        //Determine the current Whether the request is a mobile path 
        for (String mobileUrl : interceptorUrlList) { 
            } 
        }
  
    
            if(url.contains(mobileUrl)){
                flag = true; 
        //According to the intercepted request, jump to different login request paths 
        if(flag){ 
            //Mobile interface, intercept and jump to mobile login 
            WebUtils.issueRedirect(request, response, "/ddLogin"); 
        } else{ 
            //PC side, jump to PC side to log in 
            WebUtils.issueRedirect(request, response, loginUrl); 
        } 
    } }
