老师，
我的index page的登录跟退出是同时出现的
图片描述

下面是我build.gradle的dependencies

dependencies {
	compile 'org.springframework.boot:spring-boot-starter-thymeleaf'
	compile 'org.springframework.boot:spring-boot-starter-web'
	compile 'org.springframework.boot:spring-boot-starter-security'
	compile 'org.thymeleaf.extras:thymeleaf-extras-springsecurity4:3.0.2.RELEASE'
	compile 'org.springframework.boot:spring-boot-starter-data-jpa'
	compile 'org.springframework.boot:spring-boot-starter-data-elasticsearch'
	compile 'net.java.dev.jna:jna:4.3.0'
	compile 'mysql:mysql-connector-java:8.0.11'
	runtime('com.h2database:h2:1.4.193')
	testCompile 'org.springframework.boot:spring-boot-starter-test'
}

还有我的index和header.html

<html xmlns:th="http://www.thymeleaf.org"
      xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout"
      xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">
<head th:replace="fragments/header :: header">
</head>
<body>

<!-- Page content -->
<div class="container blog-content-container"> 
	<div sec:authorize="isAuthenticated()">
	    <p>已有用户登录</p>
	    <p>登录的用户为: <span sec:authentication="name"></span></p>
	    <p>用户角色为: <span sec:authentication="principal.authorities"></span></p>
	</div>
	<div sec:authorize="isAnonymous()">
	    <p>未有用户登录</p>
	</div>
</div><!-- /.container -->

<div th:replace="fragments/footer :: footer"></div>
</body>
</html>

        </div>

        <div sec:authorize="isAnonymous()">
            <a href="/login" th:href="@{~/login}" class="btn btn-outline-success my-2 my-sm-0" type="submit">登录</a>
        </div>
    </div>

</div>
</nav>
</body>
</html>

我怀疑我的那个security是不是没配置正确？
