springbootsecurity整合thymeleaf

首先创建一个springboot项目

然后加入相关依赖

接着准备一个相应的数据库

创建完成后需要在配置文件中连接相应的数据源

然后再创建service层

@Service
public class MyUserDetailService implements UserDetailsService {@Autowiredprivate UserMapper userMapper;@Autowiredprivate PermissionMapper permissionMapper;@Overridepublic UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {QueryWrapper<User> wrapper = new QueryWrapper<>();wrapper.eq("username",username);User user = userMapper.selectOne(wrapper);if (Objects.nonNull(user)){List<Permission> permissions = permissionMapper.selectByPermission(user.getUserid());List<SimpleGrantedAuthority> collect = permissions.stream().map(item -> new SimpleGrantedAuthority(item.getPercode())).collect(Collectors.toList());return new org.springframework.security.core.userdetails.User(username,user.getUserpwd(),collect);}return null;}
}

注意这里要实现UserDetailsSercvice接口并实现其中的方法

接着就是Security的配置类

@Configuration//表示该类为配置类
public class MySecurity extends WebSecurityConfigurerAdapter {@Autowiredprivate MyUserDetailService userDetailService;@Bean//一定要加Bean注解，public PasswordEncoder passwordEncoder(){PasswordEncoder passwordEncoder = new BCryptPasswordEncoder();return passwordEncoder;}
//下下面自定义的页面@Overrideprotected void configure(HttpSecurity http) throws Exception {http.formLogin().loginPage("/login.html").successForwardUrl("/success").loginProcessingUrl("/login").permitAll();http.csrf().disable();//表示禁用内置的csrfhttp.authorizeRequests().anyRequest().authenticated();//表示除了上方的路径其他都需要登入http.exceptionHandling().accessDeniedPage("/403.html");//权限不足跳转页面}@Overrideprotected void configure(AuthenticationManagerBuilder auth) throws Exception {auth.userDetailsService(userDetailService);}
}
