一個簡單的控制器,如下程式碼所示 -
package com.yiibai.web.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.servlet.ModelAndView; @Controller public class HelloController { @RequestMapping(value = { "/", "/welcome**" }, method = RequestMethod.GET) public ModelAndView welcomePage() { ModelAndView model = new ModelAndView(); model.addObject("title", "Spring Security Custom Login Form"); model.addObject("message", "This is welcome page!"); model.setViewName("hello"); return model; } @RequestMapping(value = "/admin**", method = RequestMethod.GET) public ModelAndView adminPage() { ModelAndView model = new ModelAndView(); model.addObject("title", "Spring Security Custom Login Form"); model.addObject("message", "This is protected page!"); model.setViewName("admin"); return model; } //Spring Security see this : @RequestMapping(value = "/login", method = RequestMethod.GET) public ModelAndView login( @RequestParam(value = "error", required = false) String error, @RequestParam(value = "logout", required = false) String logout) { ModelAndView model = new ModelAndView(); if (error != null) { model.addObject("error", "Invalid username and password!"); } if (logout != null) { model.addObject("msg", "You've been logged out successfully."); } model.setViewName("login"); return model; } }
5.1. 歡迎頁面 – http://localhost:8080/spsecurity-custom-login-form-xml/welcome ,結果如下圖中所示 -
5.2 嘗試存取:http://localhost:8080/spsecurity-custom-login-form-xml/admin 頁面,Spring Security將擷取請求並重定向到 /login ,並顯示您的自定義登入表單。
5.3. 如果使用者名和密碼不正確,將顯示錯誤資訊,並且Spring將重定向到網址: http://localhost:8080/spsecurity-custom-login-form-xml/login?error.
5.4. 如果使用者名和密碼都正確,Spring將重定向到原請求的URL並顯示該網頁資訊。
5.5. 嘗試登出,它會重定向到 http://localhost:8080/spsecurity-custom-login-form-xml/login?logout 頁面。
