path参数文档异常（找不到 urlTemplate）

当 用于记录 URI 路径参数时，如下所示pathParameters

@Test
public void documentGetRouteById() throws Exception {
    this.mockMvc.perform(get("/route/{id}", "FooBar")).andExpect(status().isOk())
            .andDo(document("api-getRouteById",
                    pathParameters(parameterWithName("id").description("die Routen ID"))));
}

我得到以下摘录

java.lang.IllegalArgumentException: urlTemplate not found. Did you use RestDocumentationRequestBuilders to build the request?

我很确定我做了测试设置，就像这里解释的那样。

我可能做错了什么？

（Spring REST docs 版本是 1.0.0.BUILD-SNAPSHOT）
