關於SpringSecurity配置403權限訪問頁面的完整代碼
1、未配置之前
2、開始配置
2.1 新建一個unauth.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <h1>沒有訪問的權限</h1> </body> </html>
2.2 在繼承WebSecurityConfigurerAdapter的配置類中設置
關鍵代碼:
//配置沒有權限訪問自定義跳轉的頁面 http.exceptionHandling() .accessDeniedPage("/unauth.html");
配置類完整代碼:
package com.atguigu.springsecuritydemo1.config; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder; import org.springframework.security.config.annotation.web.builders.HttpSecurity; import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter; import org.springframework.security.core.userdetails.UserDetailsService; import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder; import org.springframework.security.crypto.password.PasswordEncoder; @Configuration public class SecurityConfigTest extends WebSecurityConfigurerAdapter { @Autowired private UserDetailsService userDetailsService; @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { auth.userDetailsService(userDetailsService).passwordEncoder(password()); } @Bean PasswordEncoder password(){ return new BCryptPasswordEncoder(); } @Override protected void configure(HttpSecurity http) throws Exception { //退出配置 http.logout().logoutUrl("/logout") .logoutSuccessUrl("/test/hello") .permitAll(); //配置沒有權限訪問自定義跳轉的頁面 http.exceptionHandling().accessDeniedPage("/unauth.html"); http.formLogin() //自定義自己編寫的登陸頁面 .loginPage("/login.html") //登錄頁面設置 .loginProcessingUrl("/user/login") //登錄訪問路徑 .defaultSuccessUrl("/success.html").permitAll() //登錄成功之後,跳轉路徑 .and().authorizeRequests() //設置哪些路徑可以直接訪問,不需要認證 .antMatchers("/","/test/hello","/user/login").permitAll() //當前登錄的用戶,隻有具有admins權限才可以訪問這個路徑 //1、hasAuthority方法 //.antMatchers("/test/index").hasAuthority("admins") //2、hasAnyAuthority方法 // .antMatchers("/test/index").hasAnyAuthority("admins,manager") //3、hasRole方法 ROLE_sale .antMatchers("/test/index").hasRole("sale") //4、hasAnyRole方法 .anyRequest().authenticated() .and().csrf().disable(); //關閉csrf防護 } }
2.3 繼承UserDetailsService接口的實現類
package com.atguigu.springsecuritydemo1.service; import com.atguigu.springsecuritydemo1.entity.Users; import com.atguigu.springsecuritydemo1.mapper.UsersMapper; import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.security.core.GrantedAuthority; import org.springframework.security.core.authority.AuthorityUtils; import org.springframework.security.core.userdetails.User; import org.springframework.security.core.userdetails.UserDetails; import org.springframework.security.core.userdetails.UserDetailsService; import org.springframework.security.core.userdetails.UsernameNotFoundException; import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder; import org.springframework.stereotype.Service; import java.util.List; @Service("userDetailsService") public class MyUserDetailService implements UserDetailsService { @Autowired private UsersMapper usersMapper; @Override public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException { //調用userMapper中的方法,根據用戶名查詢數據庫 QueryWrapper<Users> wrapper=new QueryWrapper<>();//條件構造器 //where username=? wrapper.eq("username",username); Users users= usersMapper.selectOne(wrapper); //判斷 if(users==null){ //數據庫沒有用戶名,認證失敗 throw new UsernameNotFoundException("用戶名不存在!"); } List<GrantedAuthority> auths= AuthorityUtils.commaSeparatedStringToAuthorityList("admins,ROLE_sale"); //從查詢數據庫返回user對象,得到用戶名和密碼,返回 return new User(users.getUsername(),new BCryptPasswordEncoder().encode(users.getPassword()),auths); } }
3、測試
現在我故意將原先的sale改為sale1制造錯誤
啟動項目並訪問http://localhost:8111/test/index
輸入lucy 123
成功實現
