spring boot整合spring security（基本功能）

配置验证

@Component
public class CustomUserDetailsService implements UserDetailsService {

    @Autowired
    StaffMapper staffMapper;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        BCryptPasswordEncoder bCryptPasswordEncoder = new BCryptPasswordEncoder();  //加密类，
        Staff staff = staffMapper.findByAccount(username);                          //从数据库中查询
        List list = new ArrayList<>();                            //拥有的权限
        if(staff == null){
            throw new UsernameNotFoundException("用户不存在");
        }else {
            list.add(new SimpleGrantedAuthority(staff.getPower()));
        }
        org.springframework.security.core.userdetails.User security = new org.springframework.security.core.userdetails.User(staff.getStaffAccount(),bCryptPasswordEncoder.encode(staff.getStaffPassword()),list);//因为数据库中存的是名文所以password需要加密
        return security;
    }
}

继承配置类

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)//开启方法级验证
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    CustomUserDetailsService customUserDetailsService;


    @Bean
    public PasswordEncoder passwordEncoder(){
        // 使用BCrypt加密密码
        return new BCryptPasswordEncoder();
    }


    //配置自定义登入页面。如果注释掉将使用默认页面
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.formLogin()
                .loginPage("/pages/login.html")  //登入页面
                .loginProcessingUrl("/login")    //登入url  与登入表单中的action必须相同
                .usernameParameter("username")
                .passwordParameter("password")
                .defaultSuccessUrl("/pages/main.html",true)//默认登入页面  true是当输入一个不存在的页面时，进入登入页面，登入后依然进入main.html
                .failureUrl("/login?error")     //登入失败
                .and()
                .csrf().disable();              //关闭csrf过滤器


        http.logout()
                .logoutUrl("/logout")           //登出url
                .logoutSuccessUrl("/login");    //登出成功url

        http.authorizeHttpRequests()
                .antMatchers("/pages/login.html").permitAll()          //所有人都可以访问
                .antMatchers("/pages/report.html").hasRole("MANAGER")  //必须拥有MANAGER权限才可以访问。给予权限名时必须是ROLE_MANAGER才行
                .anyRequest().authenticated();     //所有的访问都需要权限


        http.headers().frameOptions().disable();   //在iframe中可以展示

    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(customUserDetailsService).passwordEncoder(passwordEncoder());
    }

}
