SpringSecurity自定義Form表單使用方法講解
背景
本系列教程,是作為團隊內部的培訓資料準備的。主要以實驗的方式來體驗SpringSecurity的各項Feature。
新建一個SpringBoot項目,起名springboot-security-form,核心依賴為Web,SpringSecurity與Thymeleaf。

實驗-HttpBasic
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {// There is no PasswordEncoder mapped for the id "null"PasswordEncoder encoder = PasswordEncoderFactories.createDelegatingPasswordEncoder();String yourPassword = "123";System.out.println("Encoded password: " + encoder.encode(yourPassword));// Config account info and permissionsauth.inMemoryAuthentication().withUser("dev").password(encoder.encode(yourPassword)).authorities("p1").and().withUser("test").password(encoder.encode(yourPassword)).authorities("p2");
}
@Override
protected void configure(HttpSecurity http) throws Exception {http.authorizeRequests().antMatchers("/user/add").hasAuthority("p1").antMatchers("/user/query").hasAuthority("p2").antMatchers("/user/**").authenticated().anyRequest().permitAll() // Let other request pass.and().httpBasic();
}

實驗-自定義登錄頁面
登錄頁面配置
@Override
protected void configure(HttpSecurity http) throws Exception {http.authorizeRequests().antMatchers("/user/add").hasAuthority("p1").antMatchers("/user/query").hasAuthority("p2").antMatchers("/user/**").authenticated().anyRequest().permitAll() // Let other request pass.and().csrf().disable() // turn off csrf, or will be 403 forbidden.formLogin() // Support form and HTTPBasic.loginPage("/login");
}
后端登錄頁面接口
@Controller
public class LoginController {@GetMapping("/login")public String login() {return "login";}@GetMapping(value = "/user/add")@ResponseBodypublic String accessResource1() {return " Access Resource 1: Add User";}@GetMapping(value = "/user/query")@ResponseBodypublic String accessResource2() {return " Access Resource 2: Query User";}
}
前端模板
<!DOCTYPE html> <html lang="en"> <head><meta charset="UTF-8"><title>Login</title> </head> <body> <form action="login" method="post"><span>用戶名</span><input type="text" name="username" /> <br><span>密碼</span><input type="password" name="password" /> <br><input type="submit" value="登錄"> </form> </body> </html>
Note:此時,需要先關閉CSRF,.csrf().disable(),否則報403;
實驗-自定義登錄接口
默認登錄頁面接口與登錄數(shù)據(jù)提交接口是同一個:/login,順著.loginPage,進入FormLoginConfigurer,源碼如下:
@Override
public FormLoginConfigurer<H> loginPage(String loginPage) {return super.loginPage(loginPage);
}
繼續(xù)進入父類的loginPage方法,
protected T loginPage(String loginPage) {setLoginPage(loginPage);updateAuthenticationDefaults();this.customLoginPage = true;return getSelf();
}
繼續(xù)跟蹤進入方法updateAuthenticationDefaults();,可以看到,如果沒有配置loginProcessingUrl,那么loginProcessingUrl與loginPage便相同。
protected final void updateAuthenticationDefaults() {if (loginProcessingUrl == null) {loginProcessingUrl(loginPage);}if (failureHandler == null) {failureUrl(loginPage + "?error");}final LogoutConfigurer<B> logoutConfigurer = getBuilder().getConfigurer(LogoutConfigurer.class);if (logoutConfigurer != null && !logoutConfigurer.isCustomLogoutSuccess()) {logoutConfigurer.logoutSuccessUrl(loginPage + "?logout");}
}
下面我們自定義登錄數(shù)據(jù)提交接口為/formLogin,此時相應的前端action也要修改。
@Override
protected void configure(HttpSecurity http) throws Exception {http.authorizeRequests().antMatchers("/user/add").hasAuthority("p1").antMatchers("/user/query").hasAuthority("p2").antMatchers("/user/**").authenticated().anyRequest().permitAll() // Let other request pass.and().csrf().disable() // turn off csrf, or will be 403 forbidden.formLogin() // Support form and HTTPBasic.loginPage("/login").loginProcessingUrl("/formLogin");
}
<form action="formLogin" method="post"><span>用戶名</span><input type="text" name="username" /> <br><span>密碼</span><input type="password" name="password" /> <br><input type="submit" value="登錄"> </form>
實驗-自定義登錄數(shù)據(jù)參數(shù)
前面我們自定義了登錄頁面,在form表單中設置用戶名、密碼分別為username, password,那為什么這樣寫呢,可以改成別的嘛?可以倒是可以,但是不能隨便改;
如果這里我們把username改為name,再次嘗試登錄,后端接口將報錯:org.springframework.security.authentication.BadCredentialsException: Bad credentials。??墒菍嶋H項目中我們的用戶名密碼就是不叫這個名字呢?我們可以進行配置.usernameParameter("name"):
@Override
protected void configure(HttpSecurity http) throws Exception {http.authorizeRequests().antMatchers("/user/add").hasAuthority("p1").antMatchers("/user/query").hasAuthority("p2").antMatchers("/user/**").authenticated().anyRequest().permitAll() // Let other request pass.and().csrf().disable() // turn off csrf, or will be 403 forbidden.formLogin() // Support form and HTTPBasic.loginPage("/login").loginProcessingUrl("/formLogin").usernameParameter("name");
}
<form action="formLogin" method="post"><span>用戶名</span><input type="text" name="name" /> <br><span>密碼</span><input type="password" name="password" /> <br><input type="submit" value="登錄"> </form>
默認的用戶名、密碼分別為username, password,我們看下SpringSecurity的源碼:
public final class FormLoginConfigurer<H extends HttpSecurityBuilder<H>> extends
AbstractAuthenticationFilterConfigurer<H, FormLoginConfigurer<H>, UsernamePasswordAuthenticationFilter> {
/**
* Creates a new instance
* @see HttpSecurity#formLogin()
*/
public FormLoginConfigurer() {
super(new UsernamePasswordAuthenticationFilter(), null);
usernameParameter("username");
passwordParameter("password");
}
}
實驗-自定義登錄失敗、成功處理器
問題:就以上個實驗3中的報錯信息為例,或當用戶名、密碼輸錯后,如何在后臺看到錯誤信息?
@Override
protected void configure(HttpSecurity http) throws Exception {http.authorizeRequests().antMatchers("/user/add").hasAuthority("p1").antMatchers("/user/query").hasAuthority("p2").antMatchers("/user/**").authenticated().anyRequest().permitAll() // Let other request pass.and().csrf().disable() // turn off csrf, or will be 403 forbidden.formLogin() // Support form and HTTPBasic.loginPage("/login").loginProcessingUrl("/formLogin").usernameParameter("name").failureHandler(new AuthenticationFailureHandler(){@Overridepublic void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {exception.printStackTrace();request.getRequestDispatcher(request.getRequestURL().toString()).forward(request, response);}});
}
常見的認證異常,這里可以看到AuthenticationException共有18個子類:

上述增加了在認證失敗時的處理:輸出錯誤信息。同理,如果想在登錄成功時直接進行一些處理(eg: 數(shù)據(jù)初始化等),可以使用以下配置:
.successHandler(new AuthenticationSuccessHandler() {@Overridepublic void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response,Authentication authentication) throws IOException, ServletException {System.out.println("Login Successfully~");// do something here: initial work or forward to different url regarding different roles...request.getRequestDispatcher("").forward(request, response);}
})
實驗-自定義登錄成功跳轉頁面
經(jīng)歷千難萬險,終于要登錄成功了。進來之后要跳轉到哪里呢?看你嘍~想跳哪里跳哪里。。
@Override
protected void configure(HttpSecurity http) throws Exception {http.authorizeRequests().antMatchers("/user/add").hasAuthority("p1").antMatchers("/user/query").hasAuthority("p2").antMatchers("/user/**").authenticated().anyRequest().permitAll() // Let other request pass.and().csrf().disable() // turn off csrf, or will be 403 forbidden.formLogin() // Support form and HTTPBasic.loginPage("/login").loginProcessingUrl("/formLogin").usernameParameter("name").failureHandler(new AuthenticationFailureHandler(){@Overridepublic void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {exception.printStackTrace();request.getRequestDispatcher(request.getRequestURL().toString()).forward(request, response);}}).successForwardUrl("/ok"); // custom login success page, a POST request
}
@Controller
public class LoginController {...@PostMapping(value = "/ok")@ResponseBodypublic String ok() {return "ok";}
}
通過.successForwardUrl("/ok")配置了登錄成功之后要跳轉的頁面路徑或接口,同時需要在后端新增/ok接口。
Note:
- 注意這里
successForwardUrl的接口必須為POST接口; - 除了
.successForwardUrl("/ok");,還可以使用.defaultSuccessUrl("/ok");或者.defaultSuccessUrl("/ok", true);第二個參數(shù)true表示不管是從哪個地址進來,登錄后全部跳轉到指定的地址,此時與successForwardUrl效果相同,默認為false - 當然,除了登錄成功后的跳轉,還有登錄失敗后的跳轉:
failureForwardUrl。
實驗-自定義退出接口
默認的退出接口是/logout,可進行配置:
@Override
protected void configure(HttpSecurity http) throws Exception {http.authorizeRequests().antMatchers("/user/add").hasAuthority("p1").antMatchers("/user/query").hasAuthority("p2").antMatchers("/user/**").authenticated().anyRequest().permitAll() // Let other request pass.and().csrf().disable() // turn off csrf, or will be 403 forbidden.formLogin() // Support form and HTTPBasic.loginPage("/login").loginProcessingUrl("/formLogin").usernameParameter("name").failureHandler(new AuthenticationFailureHandler(){@Overridepublic void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {exception.printStackTrace();request.getRequestDispatcher(request.getRequestURL().toString()).forward(request, response);}}).successForwardUrl("/ok") // custom login success page, a POST request.and().logout().logoutUrl("/leave");}
上述配置將退出接口改為/leave。在默認的退出過程中,還做了諸如清除認證信息和使Session失效等工作:
public class SecurityContextLogoutHandler implements LogoutHandler {
protected final Log logger = LogFactory.getLog(this.getClass());
private boolean invalidateHttpSession = true;
private boolean clearAuthentication = true;
// ~ Methods
// ==========================================
/**
* Requires the request to be passed in.
*
* @param request from which to obtain a HTTP session (cannot be null)
* @param response not used (can be <code>null</code>)
* @param authentication not used (can be <code>null</code>)
*/
public void logout(HttpServletRequest request, HttpServletResponse response,
Authentication authentication) {
Assert.notNull(request, "HttpServletRequest required");
if (invalidateHttpSession) {
HttpSession session = request.getSession(false);
if (session != null) {
logger.debug("Invalidating session: " + session.getId());
session.invalidate();
}
}
if (clearAuthentication) {
SecurityContext context = SecurityContextHolder.getContext();
context.setAuthentication(null);
}
SecurityContextHolder.clearContext();
}
