Spring boot Can'；t通过自定义注销处理程序注销

Spring boot Can'；t通过自定义注销处理程序注销,spring-boot,spring-security,Spring Boot,Spring Security,在我的spring boot应用程序中，我想添加注销链接在模板welcome.html中： <!DOCTYPE HTML> <html xmlns:th="http://www.thymeleaf.org"> <head> <meta charset="UTF-8"/> <title th:text="${appName}">Template title</title> <body> <h

在我的spring boot应用程序中，我想添加注销链接

在模板welcome.html中：

<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8"/>
    <title th:text="${appName}">Template title</title>
<body>
<h1>Welcome to <span th:text="${appName}">Our App</span></h1>
<h2>Dictionaries:</h2>
<p><a href="/categories">Categories</a></p>
<p><a href="/users">Users</a></p>
<p><a href="/logout">Logout</a></p>
</body>
</html>

我的经纪人：

public class CustomLogoutSuccessHandler extends SimpleUrlLogoutSuccessHandler implements LogoutSuccessHandler {
    private static Logger logger = LogManager.getLogger(CustomLogoutSuccessHandler.class);

    @Override
    public void onLogoutSuccess(
            HttpServletRequest request,
            HttpServletResponse response,
            Authentication authentication)
            throws IOException, ServletException {
        logger.info("onLogoutSuccess:");
        // some custom logic here
        response.sendRedirect(request.getContextPath() + "/login.html");
    }
}

正如您所看到的，它只是转发到登录页面

但是，当我在注销链接上单击welcome.html时，方法

onLogoutSuccess

不会被调用，我会得到错误页面：

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

Sun Jan 26 18:21:53 EET 2020
There was an unexpected error (type=Not Found, status=404).
No message available

将重定向到执行

获取请求的“/logout”
。

除非您在“/logout”
处呈现页面，否则您将收到404
默认情况下，只有当POST
请求“/logout”
时才会触发注销
因为您使用的是Thymeleaf，所以您可以使用类似这样的东西来注销
<form action="#" th:action="@{/logout}" method="post">
    <input type="submit" value="Logout" />
</form>



<form action="#" th:action="@{/logout}" method="post">
    <input type="submit" value="Logout" />
</form>
