我很难启动 Spring 测试——在测试时，占位符似乎没有在主程序中得到解决。例如，有一个 RESTController 方法：

@RequestMapping("${hello_path}")
private String helloWorld() {
    return env.getProperty("hello_content");
}

如您所见，@RequestMapping注释中有一个占位符。

当我手动测试它时它可以工作（即，端点已创建并可访问），但程序测试失败了：

@Test
public void searchReqController_saysHello() throws Exception {
    //given
    final String helloPath = env.getProperty("hello_path");
    final String helloContent = env.getProperty("hello_content");

    //when-then
    this.mockSearchReqController.perform(get(helloPath)).andExpect
                (status().isOk()).andExpect(content().string(helloContent));
}

结果是

Invalid mapping on handler class [ebi.ensembl.ftpsearchapi.SearchRequestController]: private java.lang.String ebi.ensembl.ftpsearchapi.SearchRequestController.helloWorld()
java.lang.IllegalStateException: Invalid mapping on handler class [ebi.ensembl.ftpsearchapi.SearchRequestController]: private java.lang.String ebi.ensembl.ftpsearchapi.SearchRequestController.helloWorld()

添加@EnableWebMvc 以使@RestController 工作。还尝试在测试类中调用控制器时添加 $.hello_path
