Spring boot Security 登陆安全配置

实现的效果

　　访问url时，如果未登录时跳转到Login界面，要求用户登陆，如果登陆过返回请求的数据。

效果图

访问数据时，未登录返回login界面

登陆操作

登陆成功进入登出界面

登陆成功后再次访问数据

POM 文件

加入 Security 配置，数据库使用maybatis。

WebSecurityConfigurerAdapter配置Security信息

1.  authorizeRequests() .antMatchers("/user/*").permitAll()  .anyRequest().authenticated() 意思代表 /user 不需要进行授权认证，其他都需要认证。

2 .formLogin().loginPage("/login.html").loginProcessingUrl("/signin").successHandler(successHandler).failureHandler(failureHandler) 设置的登陆界面，和登陆的url 以及登陆成功的handler和失败的handler。

3 .usernameParameter("username").passwordParameter("password").permitAll()  用户名和密码的传参数 

4 .logout().logoutUrl("/signout").logoutSuccessHandler(logoutSuccessHandler).permitAll();  登出url ，以及handler 

5 .csrf().disable()

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private AjaxAuthSuccessHandler successHandler;

    @Autowired
    private AjaxAuthFailureHandler failureHandler;

    @Autowired
    private AjaxLogoutSuccessHandler logoutSuccessHandler;

    @Autowired
    private UserDetailsServiceImpl userDetailsService;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests().antMatchers("/user/*").permitAll() .anyRequest().authenticated()
                .and()
                .csrf().disable()
                .formLogin().loginPage("/login.html").loginProcessingUrl("/signin").successHandler(successHandler).failureHandler(failureHandler)
                .usernameParameter("username").passwordParameter("password").permitAll()
                .and()
                .logout().logoutUrl("/signout").logoutSuccessHandler(logoutSuccessHandler).permitAll();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService).passwordEncoder(new PasswordEncoder() {
            @Override
            public String encode(CharSequence charSequence) {
                return charSequence.toString();
            }

            @Override
            public boolean matches(CharSequence charSequence, String s) {
                return s.equals(charSequence.toString());
            }
        });
    }
}

SimpleUrlAuthenticationSuccessHandler

登陆成功时

@Component
public class AjaxAuthSuccessHandler extends SimpleUrlAuthenticationSuccessHandler {

    private static final Logger logger = LoggerFactory.getLogger(AjaxAuthSuccessHandler.class);

    @Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
        logger.info("Authentication success, {} login successfully", request.getParameter("username"));
        response.setStatus(HttpServletResponse.SC_OK);
        response.sendRedirect("/home.html");
    }
}

fail

@Component
public class AjaxAuthFailureHandler extends SimpleUrlAuthenticationFailureHandler {

    private static final Logger logger = LoggerFactory.getLogger(AjaxAuthFailureHandler.class);

    @Override
    public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {
        logger.info("Authentication error, {} login failed", request.getParameter("username"));
        response.sendError(HttpServletResponse.SC_UNAUTHORIZED, "Authentiaction Failed");
    }
}

loginout success

@Component
public class AjaxLogoutSuccessHandler implements LogoutSuccessHandler {

    private static final Logger logger = LoggerFactory.getLogger(AjaxLogoutSuccessHandler.class);

    @Override
    public void onLogoutSuccess(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Authentication authentication) throws IOException, ServletException {
        httpServletResponse.setStatus(HttpServletResponse.SC_OK);
        logger.info("Logout successfully, session id: {}", httpServletRequest.getSession().getId());
    }
}

UserDetailsService

@Service
public class UserDetailsServiceImpl implements UserDetailsService {

    private Map<String, String> userRepository = new HashMap<>();

    @PostConstruct
    private void init() {
        userRepository.put("zhangshan", "123456");
        userRepository.put("guo", "123456");
    }

    @Override
    public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
        return new User(s, userRepository.get(s), new ArrayList<>());
    }
}
