这篇文章主要介绍了基于spring security实现登录注销功能过程解析,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
1、引入maven依赖
org.springframework.boot spring-boot-starter-security
2、Security 配置类 说明登录方式、登录页面、哪个url需要认证、注入登录失败/成功过滤器
@Configuration
public class BrowserSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private SecurityProperties securityProperties;
@Autowired
private MyAuthenticationSuccessHandler mySuccessHandler;
@Autowired
private MyAuthenticationFailHandler myFailHandler;
@Bean
public PasswordEncoder passwordEncoder(){
return new BCryptPasswordEncoder();
}
@Override
protected void configure(HttpSecurity http) throws Exception {
//登录成功的页面地址
String redirectUrl = securityProperties.getLoginPage();
//basic 登录方式
// http.httpBasic()
//表单登录 方式
http.formLogin()
.loginPage("/authentication/require")
//登录需要经过的url请求
.loginProcessingUrl("/authentication/form")
.successHandler(mySuccessHandler)
.failureHandler(myFailHandler)
.and()
//请求授权
.authorizeRequests()
//不需要权限认证的url
.antMatchers("/authentication
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
log.info("登录用户名:"+username);
String password = passwordEncoder.encode("123456");
//User三个参数 (用户名+密码+权限)
//根据查找到的用户信息判断用户是否被冻结
log.info("数据库密码:"+password);
return new User(username,password, AuthorityUtils.commaSeparatedStringToAuthorityList("admin"));
}
}
5、登录路径请求类,.loginPage("/authentication/require")
@RestController
@Slf4j
@ResponseStatus(code = HttpStatus.UNAUTHORIZED)
public class BrowerSecurityController {
private RequestCache requestCache = new HttpSessionRequestCache();
private RedirectStrategy redirectStrategy = new DefaultRedirectStrategy();
@Autowired
private SecurityProperties securityProperties;
@RequestMapping("/authentication/require")
public SimpleResponse requireAuthentication(HttpServletRequest request, HttpServletResponse response) throws IOException {
//拿到请求对象
SavedRequest savedRequest = requestCache.getRequest(request, response);
if (savedRequest != null){
//获取 跳转url
String targetUrl = savedRequest.getRedirectUrl();
log.info("引发跳转的请求是:"+targetUrl);
//判断 targetUrl 是不是 .html 结尾, 如果是:跳转到登录页(返回view)
if (StringUtils.endsWithIgnoreCase(targetUrl,".html")){
String redirectUrl = securityProperties.getLoginPage();
redirectStrategy.sendRedirect(request,response,redirectUrl);
}
}
//如果不是,返回一个json 字符串
return new SimpleResponse("访问的服务需要身份认证,请引导用户到登录页");
}
6、postman请求测试
(1)未登录请求
(2)、登录
(3)、再次访问
(4)、注销
