[tomcat-embed-core-9.0.50.jar:9.0.50] at java.lang.Thread.run(Thread.java:748) [na:1.8.0_291]2、错误场景和条件我的一个controller的方法的权限设置如下PreAuthorize(“hasAuthority(‘org:position:user:count’)”)PreAuthorize(hasAuthority(org:position:user:count)) GetMapping(/getDataList) IFdApiResult getDataList(Long departmentId) { if(departmentId null) { return FdApiResult.fail(Id不能为空); } LambdaQueryWrapperPosition queryWrapper Wrappers.PositionlambdaQuery() .eq(Position::getDepartmentId, departmentId); return FdApiResult.success(baseService.list(queryWrapper)); }检查我的WebSecurityConfigurerAdapter子类SecurityConfigWithoutUserDetailConfiguration EnableWebSecurity EnableGlobalMethodSecurity(prePostEnabled true) //开启方法注入的权限校验 public class SecurityConfigWithoutUserDetail extends WebSecurityConfigurerAdapter { Autowired CustomerAuthenticationProvider authenticationProvider; /** * 登录认证成功的处理方式 */ Autowired MyAuthenticationSuccessHandler myAuthenticationSuccessHandler; /** * 登录认证失败的处理方式 */ Autowired MyAuthenticationFailureHandler myAuthenticationFailureHandler; /** * 未登录认证的处理方式 */ Autowired MyAuthenticationEntryPoint myAuthenticationEntryPoint; /** * 权限不足的处理方式 */ Autowired MyAccessDeniedHandler myAccessDeniedHandler; Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { auth.authenticationProvider(authenticationProvider); } Override protected void configure(HttpSecurity http) throws Exception { http.csrf().disable()//如果不关闭csrf所有访问请求都无法响应。 //配置需要认证的请求 .authorizeRequests() .antMatchers( /api/sysmgr/identity/login).permitAll() .antMatchers(/api/redis/test/**,/api/sysmgr/identity/testRedis,/api/redis/test/setObjectExpireKey).anonymous() .antMatchers(/websocket/**/**/**).permitAll()//放行websocket的请求格式需要和/websocket/{projId}/{platform}/{sid}匹配。 .anyRequest() .authenticated() .and() .exceptionHandling() .authenticationEntryPoint(myAuthenticationEntryPoint)//未登录认证 .accessDeniedHandler(myAccessDeniedHandler) //无权限访问的处理器 ; } Bean Override public AuthenticationManager authenticationManagerBean() throws Exception { return super.authenticationManagerBean(); } }发现我自定义的myAccessDeniedHandler类没有调用。否则应该提示【没有权限访问】信息Component(myAccessDeniedHandler) public class MyAccessDeniedHandler implements AccessDeniedHandler { Override public void handle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, AccessDeniedException e) throws IOException, ServletException { // 跨域处理 httpServletResponse.setHeader(Access-Control-Allow-Origin, *); // 允许的请求方法 httpServletResponse.setHeader(Access-Control-Allow-Methods, GET,POST,OPTIONS,PUT,DELETE); // 允许的请求头 httpServletResponse.setHeader(Access-Control-Allow-Headers, httpServletRequest.getHeader(Access-Control-Request-Headers)); // 设置响应头 httpServletResponse.setContentType(application/json;charsetutf-8); //通过httpServletRepsonse返回给前台 //ObjectMapper类的writeValueString方法是springboot中的jackson提供的将类或其他对象转换成json格式的方法 httpServletResponse.getWriter().write(new ObjectMapper().writeValueAsString(FdApiResult.success().setMsg(没有权限访问))); } }3、错误原因分析原因是PreAuthorize 注解的异常抛出AccessDeniedException异常不会被accessDeniedHandler捕获而是会被全局异常捕获。4、错误解决办法所以修改我项目中的全局异常处理类ExceptionHandlerAdvice添加一个新的方法/*** 捕捉AccessDeniedExceptionspring security抛出的无权限访问的异常信息* param e* return*/ExceptionHandler(AccessDeniedException.class)public IFdApiResult handleAccessDeniedException(AccessDeniedException e) {return FdApiResult.of(HttpStatus.FORBIDDEN.value(), ACCESS_DENIED_MSG);}完成的类效果如下Slf4j RestControllerAdvice public class ExceptionHandlerAdvice { private static final String ERROR_MSG 服务器端错误请联系系统管理员; private static final String ACCESS_DENIED_MSG 无权限访问请联系系统管理员; ExceptionHandler(Throwable.class) public IFdApiResult exception(Throwable throwable) { log.error(ERROR_MSG, throwable); return FdApiResult.of(HttpStatus.INTERNAL_SERVER_ERROR.value(), ERROR_MSG); } ExceptionHandler(BizException.class) public IFdApiResult bizException(BizException throwable) { log.error(throwable.getMessage(), throwable); return FdApiResult.of(throwable.getCode(), throwable.getMessage()); } /** * 捕捉AccessDeniedExceptionspring security抛出的无权限访问的异常信息 * param e * return */ ExceptionHandler(AccessDeniedException.class) public IFdApiResult handleAccessDeniedException(AccessDeniedException e) { return FdApiResult.of(HttpStatus.FORBIDDEN.value(), ACCESS_DENIED_MSG); } }重新测试
