这篇文章将为大家详细讲解有关Spring cloud中怎么利用zuul实现单点登录，文章内容质量较高，因此小编分享给大家做个参考，希望大家阅读完这篇文章后对相关知识有一定的了解。
1.参考
先检查有否认证的token，如果没有则抛出错误，再转到getRedirectForAuthorization，这下就转向了redirect的请求处理
1.ExceptionTranslationFilter
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain)
throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) req;
HttpServletResponse response = (HttpServletResponse) res;
try {
chain.doFilter(request, response);
logger.debug("Chain processed normally");
}
catch (IOException ex) {
throw ex;
}
catch (Exception ex) {
// Try to extract a SpringSecurityException from the stacktrace
Throwable[] causeChain = throwableAnalyzer.determineCauseChain(ex);
RuntimeException ase = (AuthenticationException) throwableAnalyzer
.getFirstThrowableOfType(AuthenticationException.class, causeChain);
if (ase == null) {
ase = (AccessDeniedException) throwableAnalyzer.getFirstThrowableOfType(
AccessDeniedException.class, causeChain);
}
if (ase != null) {
handleSpringSecurityException(request, response, chain, ase);
}handleSpringSecurityException这块就将转向login
DelegatingAuthenticationEntryPoint
public void commence(HttpServletRequest request, HttpServletResponse response,
AuthenticationException authException) throws IOException, ServletException {会计算到这个类上,LoginUrlAuthenticationEntryPoint,它将生成redirect
org.springframework.security.oauth3.client.token.grant.code.AuthorizationCodeAccessTokenProvider.obtainAccessToken(AuthorizationCodeAccessTokenProvider.java:205)
见下面的异步堆栈：

预过滤器:
0 = {ServletDetectionFilter@9816} ，确定是否支持Dispatch请求
1 = {Servlet30WrapperFilter@9817} ,进行Servlet30请求包装
2 = {FormBodyWrapperFilter@9818} ,FormBody包装
3 = {DebugFilter@9819}
4 = {PreDecorationFilter@9820}
5 = {AuthenticationHeaderFilter@9821} ,addIgnoredHeaders不知道是啥意思
6 = {OAuth3TokenRelayFilter@9441} ,这个被跳过了,不知道是否可以直接disable算了
ctx.addZuulRequestHeader("authorization", ctx.get(TOKEN_TYPE) + " " + getAccessToken(ctx));
正式过滤器：
0 = {RibbonRoutingFilter@9478}
1 = {SimpleHostRoutingFilter@9669}
2 = {SendForwardFilter@9692}
2.zuul中主要的类
2.1 ZuulController
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {}
2.2 RibbonRoutingFilter
