- 引入依赖
<!-- security --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency>
- 配置 SecurityConfigbr/>@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {@Autowired UserDetailServiceImpl userDetailService; @Autowired LoginSuccessHandler loginSuccessHandler; @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { //自定义用户验证和加密方式 auth.userDetailsService(userDetailService).passwordEncoder(new BCryptPasswordEncoder()); } @Override protected void configure(HttpSecurity http) throws Exception { http.formLogin() // 定义当需要用户登录时候,转到的登录页面。 // .loginPage("/login.html") //自定义登录页面 // .loginProcessingUrl("/login") //自定义登录接口地址 .successHandler(loginSuccessHandler) .and() // 定义哪些URL需要被保护、哪些不需要被保护 .authorizeRequests().antMatchers("/login").permitAll() //不需要保护的URL .anyRequest() // 任何请求,登录后可以访问 .authenticated() .and() .logout().logoutSuccessUrl("/login").permitAll() // 登出 .and() .csrf().disable(); } }
3.用户验证处理
@Component
public class UserDetailServiceImpl implements UserDetailsService {
/**
* 用户校验
* @param s
* @return
* @throws UsernameNotFoundException
*/
@Override
public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
Collection<GrantedAuthority> collection = new ArrayList<>();//权限集合
String password = new BCryptPasswordEncoder().encode("123456");
User user = new User(s,password,collection);
return user;
}
}
4.登录成功后处理
@Component
public class LoginSuccessHandler implements AuthenticationSuccessHandler {
@Override
public void onAuthenticationSuccess(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Authentication authentication) throws IOException, ServletException {
httpServletResponse.setContentType("application/json;charset=UTF-8");
httpServletResponse.getWriter().write(authentication.getName());
}
}
HttpSecurity 类还有很可以使用的函数
