SpringSecurity自定义响应异常信息

SpringSecurity自定义响应异常信息

此处的异常信息设置的话,其中还是有坑的,比如你想自定义token过期信息,无效token这些,如果按照SpringSecurity的设置是不会生效的,需要加到资源的配置中。

如果只是SpringSecurity的话,只需要实现AccessDeniedHandler和AuthenticationEntryPoint这2个接口就可以了。他们都是在ExceptionTranslationFilter中生效的。

AuthenticationEntryPoint 用来解决匿名用户访问无权限资源时的异常

ruAccessDeineHandler 用来解决认证过的用户访问无权限资源时的异常

如果你想自定义token过期的话,需要实现AuthenticationEntryPoint这个接口,因为token过期了,访问的话也算是匿名访问。但是SpringSecurity的过滤器链中其实是有顺序的,校验token的OAuth2AuthenticationProcessingFilter在它前面,导致一直没有办法生效,所有需要添加到资源的配置上,demo如下:

/**
 * @author WGR
 * @create 2021/8/23 -- 16:52
 */
@Component
public class SimpleAuthenticationEntryPoint implements AuthenticationEntryPoint {

    @Override
    public void commence(HttpServletRequest request, HttpServletResponse response,
                         AuthenticationException authException) throws ServletException {
        Throwable cause = authException.getCause();
        try {
            if (cause instanceof InvalidTokenException) {
                Map map = new HashMap();
                map.put("error", "无效token");
                map.put("message", authException.getMessage());
                map.put("path", request.getServletPath());
                map.put("timestamp", String.valueOf(new Date().getTime()));
                response.setContentType("application/json");
                response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
                try {
                    ObjectMapper mapper = new ObjectMapper();
                    mapper.writeValue(response.getOutputStream(), map);
                } catch (Exception e) {
                    throw new ServletException();
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

则可以生效,返回信息具体如下:SpringSecurity自定义响应异常信息

如果想设置没有权限的自定义异常信息的话:

/**
 * @author WGR
 * @create 2021/8/23 -- 17:09
 */
@Component
public class SimpleAccessDeniedHandler implements AccessDeniedHandler {
    @Override
    public void handle(HttpServletRequest request, HttpServletResponse response, AccessDeniedException accessDeniedException) throws IOException, ServletException {
        Map map = new HashMap();
        map.put("message", "无权操作");
        map.put("path", request.getServletPath());
        map.put("timestamp", String.valueOf(new Date().getTime()));
        response.setContentType("application/json");
        response.setStatus(HttpServletResponse.SC_FORBIDDEN);
        try {
            ObjectMapper mapper = new ObjectMapper();
            mapper.writeValue(response.getOutputStream(), map);
        } catch (Exception e) {
            throw new ServletException();
        }
    }
}

把它设置到springsecurity中,添加进去就可以了,如果不是想要捕获token过期的话,就直接添加进去也可以
