我有一个spring-boot-thymeleaf应用程序，我在其中进行requestmapping调用
如果你看一下图片load-products.jpg，我得到了正确的列表，但只有在我第一次启动调用时才会出现这种情况http://localhost：8080/services/searchbydepartment？department=制冰机
我有链接如果你向下滚动你会看到链接
全制冷制冰机。。。。。。。

如果我第二次点击任何链接调用这个url
http://localhost：8080/searchbydepartment？department=制冰机
会产生错误请参见附件

因此，如果我回到我的thymeleaf页面并将服务附加到我所有的th:href，比如th:href=“@{services/searchbydepartment}
然后我得到了一个双重服务，在我的呼吁，这是创造另一个错误
这是其他电话正在创建的http://localhost：8080/services/services/searchbydepartment？department=制冷http://localhost：8080/services/services/searchbydepartment？department=食品准备
您可以看到单词services出现了两次，这造成了一个no explicit mapping错误，因为它找不到urlMap
我尝试了一切重定向，删除字服务从控制器添加到thymeleaf和它不工作。。怎么回事。。代码在我看来是这样的
th:href=“@{services/searchbydepartment（department='icemachines'）}
控制器将@requestmapping（value=“/services”）作为注解，或将其添加到方法调用中，如@requestmapping（{“services/searchbydepartment”}）
目录结构对我来说似乎很好，但这段代码不起作用

<div class="prod-list">
        <a th:href="@{services/allList}" th:classappend="${activeAll}? 'active'"
           class="list-group-item">All</a>
        <a class="categories list-group-item ice" th:href="@{services/searchByDepartment(department='iceMachines')}"
           th:classappend="${activeIceMachines} ? 'active'">Ice Machine</a>
        <a class="categories list-group-item refrigeration" th:href="@{services/searchByDepartment(department='refrigeration')}"
           th:classappend="${activeRefrigeration} ? 'active'">Refrigeration</a>
        <a class="categories list-group-item cook" th:href="@{services/searchByDepartment(department='cookingEquipment')}"
           th:classappend="${activeCooking} ? 'active'">Cooking Equipment</a>
        <a class="categories list-group-item cook" th:href="@{services/searchByDepartment(department='foodPreparation')}"
           th:classappend="${activeCooking} ? 'active'">Food Preparation</a>
        <a class="categories list-group-item bar" th:href="@{services/searchByDepartment(department='barEquipment')}"
           th:classappend="${activeBar} ? 'active'">Bar Equipment</a>
    </div>
