前期準備
package com.example.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @Controller public class TestController { @RequestMapping("/") public String index(){ return "index"; } @RequestMapping("/toLogin") public String toLogin(){ return "views/login"; } @RequestMapping("/level1/{id}") public String level1(@PathVariable("id") int id){ return "views/level1/"+id; } @RequestMapping("/level2/{id}") public String level2(@PathVariable("id") int id){ return "views/level2/"+id; } @RequestMapping("/level3/{id}") public String level3(@PathVariable("id") int id){ return "views/level3/"+id; } }
引入spring-boot-starter-security模塊
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency>
認識SpringSecurity的幾個(gè)重要的類(lèi)
SpringSecurity---授權(認真看代碼和注釋?zhuān)?/p>
//授權 @Override protected void configure(HttpSecurity http) throws Exception { http.authorizeRequests().antMatchers("/").permitAll() //首頁(yè)所有人可以訪(fǎng)問(wèn) .antMatchers("/level1/**").hasRole("vip1") //level1下的頁(yè)面,VIP1可以訪(fǎng)問(wèn) .antMatchers("/level2/**").hasRole("vip2") .antMatchers("/level3/**").hasRole("vip3"); //開(kāi)啟自動(dòng)配置的登錄功能, //即,沒(méi)有登錄的時(shí)候,除了首頁(yè),其他頁(yè)面都訪(fǎng)問(wèn)不了,這時(shí)候,你訪(fǎng)問(wèn)其他頁(yè)面的時(shí)候, //它直接跳轉到它內置的登陸頁(yè)面,讓你登錄 http.formLogin(); http.formLogin().loginPage("/toLogin");//自定義登錄頁(yè),將自定義的登錄頁(yè)替換掉內置的登錄頁(yè) //用來(lái)處理用戶(hù)登錄提交的表單 http.formLogin().usernameParameter("username") .passwordParameter("password") .loginPage("/toLogin") .loginProcessingUrl("/login"); //開(kāi)啟自動(dòng)配置的注銷(xiāo)的功能 // /logout 注銷(xiāo)請求 http.logout(); http.csrf().disable();//關(guān)閉csrf功能:跨站請求偽造,默認只能通過(guò)post方式提交logout請求 http.logout().logoutSuccessUrl("/");//注銷(xiāo)成功就返回首頁(yè) //開(kāi)啟記住我功能 http.rememberMe(); http.rememberMe().rememberMeParameter("remember");//在自定義登錄頁(yè)添加 記住我 }
SpringSecurity---認證(認真看代碼和注釋?zhuān)?/p>
//認證 @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { /* auth.inMemoryAuthentication().withUser("xiaomi").password("123").roles("vip1") 這樣寫(xiě)是不行的,會(huì )出現500錯誤。 原因:密碼沒(méi)有加密 Spring security 5.0中新增了多種加密方式,也改變了密碼的格式。 要想我們的項目還能夠正常登陸,需要修改一下configure中的代碼。我們要將前端傳過(guò)來(lái)的密碼進(jìn)行某種方式加密 spring security 官方推薦的是使用bcrypt加密方式。 這里通過(guò) passwordEncoder(new BCryptPasswordEncoder()) 的方式進(jìn)行加密 */ // 在內存中定義認證的規則 auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder()) .withUser("xiaolong").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1") .and() .withUser("xiaomi").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1","vip2") .and() .withUser("xiaohu").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1","vip2","vip3"); //在jdbc中定義認證的規則 //auth.jdbcAuthentication() }
