项目中新近添加了Spring Security安全组件,前期没怎么用过,加之新版本少有参考,踩坑四天,终完成初步解决方案.其实很简单,Spring Security5相比之前版本少了许多配置,操作起来更轻量
SpringSecurity5在执行登录认证时,需预设加密策略.
坑一:加密策略配置,验密始终不通过,报错401
坑二:本地重写的UserDetailsService实现类在注入的时候找不到,目前图省事直接用了 @Qualifier制定
其它,实体类user实现UserDetails,role实现GrantedAuthority与之前版本并有太大变动,可参考很多,不做赘述
代码如下:
/**
* 项目中重写的 UserDetailsService接口的实现类,需指定
*/
@Qualifier("userService")
@Autowired
private UserDetailsService userDetailsService;
/**
* 初始验证登录 从内存中取密码
* @param auth
* @throws Exception
*/
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService).passwordEncoder(new BCryptPasswordEncoder());
}
Springboot2.0.3处理跨域的时候特别简单,只需要在
@EnableWebSecurity @Configuration @EnableGlobalMethodSecurity(prePostEnabled = true) @Order(-1) 等修饰下的配置类中的HttpSecurity中,加上 cors()即可,完全不需要写过滤器包装HttpServletResponse的操作 登录报错403,权限不足 这里的解决方案很多,因为本文项目不大,直接关闭 csrf (跨站请求伪造)即可 同上,csrf().disable()即可. 最大坑--跨域打开,每次登录返回为匿名用户anonymousUser 问题描述: 跨域已打开,使用Swagger访问都没有问题,前后端分离时,SpringSecurity也正常工作,最终还是登录不成功,返回匿名用户 关闭匿名用户即 anonymous().disable(),直接报错401,用户名或密码错误 遇到这个问题,一直纠结在跨域上,却没有深入去查看前端http请求上给出的信息,原因很简单,登录时重定向的问题 在HttpSecurity中,在选择 formLogin()时,其后会选择各种成功失败的url,然后代码上去实现相关的接口,其实就入坑了. 注意:在前端使用ajax登录时,SpringSecurity只能通过重写相关成功/失败/退出等的处理器handler来完成相关处理逻辑 完整配置类代码:
@EnableWebSecurity
@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
@Order(-1)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
CustomizeAuthenticationSuccessHandler customizeAuthenticationSuccessHandler;
@Autowired
CustomizeAuthenticationFailHandler customizeAuthenticationFailHandler;
@Autowired
CustomizeAuthenticationAccessDenied customizeAuthenticationAccessDenied;
@Autowired
CustomizeAuthenticationLogout customizeAuthenticationLogout;
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable()
.anonymous().disable()
.cors().and().httpBasic()
.and()
// 登录成功页面与登录失败页面
.formLogin()
.successHandler(customizeAuthenticationSuccessHandler).failureHandler(customizeAuthenticationFailHandler).permitAll().and()
// 权限不足,即403时跳转页面
.exceptionHandling().accessDeniedHandler(customizeAuthenticationAccessDenied).authenticationEntryPoint(new UnauthorizedEntryPoint())
.and().logout().logoutSuccessHandler(customizeAuthenticationLogout).permitAll().and()
.authorizeRequests().antMatchers(HttpMethod.OPTIONS).permitAll()
// 无需权限 即可访问
.antMatchers("/logout").permitAll()
// 需要USER角色才可访问
.antMatchers("/person/**").hasRole("PERSON")
// 需要ADMIN角色才可访问
.antMatchers("/user/**").hasRole("ADMIN");
}
/**
* 项目中重写的 UserDetailsService接口的实现类,需指定
*/
@Qualifier("userService")
@Autowired
private UserDetailsService userDetailsService;
/**
* 初始验证登录 从内存中取密码
* @param auth
* @throws Exception
*/
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService).passwordEncoder(new BCryptPasswordEncoder());
}
}
重写的登录成功处理器代码如下:
@Component
public class CustomizeAuthenticationSuccessHandler implements AuthenticationSuccessHandler {
private static final Logger logger = LoggerFactory.getLogger(CustomizeAuthenticationSuccessHandler.class);
@Override
public void onAuthenticationSuccess(HttpServletRequest request,
HttpServletResponse response, Authentication authentication)
throws IOException, ServletException {
logger.info("AT onAuthenticationSuccess(...) function!");
WebAuthenticationDetails details = (WebAuthenticationDetails) SecurityContextHolder.getContext().getAuthentication().getDetails();
logger.info("login--IP:"+details.getRemoteAddress());
SecurityContext context = SecurityContextHolder.getContext();
Authentication authentication1 = context.getAuthentication();
Object principal = authentication1.getPrincipal();
Object principal1 = authentication.getPrincipal();
String name = authentication.getName();
logger.info("login--name:"+name+" principal:"+principal+" principal1:"+principal1);
PrintWriter out = null;
try {
out = response.getWriter();
out.append(JSONObject.toJSONString(ResponseData.ok().putDataValue("user",principal)
.putDataValue("name",name)));
} catch (IOException e){
e.printStackTrace();
}finally {
if (out != null) {
out.close();
}
}
}
}
