Java 缺少方法public void的依赖项
我有以下代码:Java 缺少方法public void的依赖项,java,html,http,jersey,jackson,Java,Html,Http,Jersey,Jackson,我有以下代码: @Path("/automation/devices") @Singleton public class DevicesWebService { private AppiumServerManager appiumServerManager; private AdbService adbService; private DevicesService deviceService; public DevicesWebService() {
@Path("/automation/devices")
@Singleton
public class DevicesWebService {
private AppiumServerManager appiumServerManager;
private AdbService adbService;
private DevicesService deviceService;
public DevicesWebService() {
this(new AdbServiceLocal(), new AppiumServerManagerLocal());
}
@VisibleForTesting
public DevicesWebService(AdbService adbService, AppiumServerManagerLocal AppiumServerManager) {
this.adbService = adbService;
this.appiumServerManager = AppiumServerManager;
}
@GET
@Produces(MediaType.TEXT_PLAIN)
public String getMessage() {
return "welocme to devices web-service";
}
@POST
@Consumes({MediaType.APPLICATION_JSON})
@Produces({MediaType.TEXT_PLAIN})
@Path("/acquireDevice/{device}/{port}")
public Response acquireDevice(@PathParam("device") Device device, @PathParam("port") Integer port) throws
Exception {
try {
deviceService.acquireDevice(device, port);
} catch (RuntimeException e) {
return Response.status(Response.Status.NOT_FOUND).build();
}
return Response.status(Response.Status.OK).build();
}
//
public static void main(String[] args) throws IOException {
HttpServer server = HttpServerFactory.create("http://localhost:9998/");
server.start();
System.out.println("Server running");
System.out.println("Visit: http://localhost:9998/automation/devices");
}
}
我的代码在运行时失败,出现以下异常:

如果我注释掉公共响应设备
一切正常
我也尝试删除``但仍有一个错误:

如何解决此问题?正如@peeskillet所说,
@PathParam
不应用于传递对象,因为它更常用于指定一个变量,用于标识您操作的资源/对象(例如,在您的情况下,我可能会使用acquireDevice/{deviceId}/{port}
如果说,id事先有任何意义)
使用它,就像你现在所做的一样,当你在测试或者需要查看日志中发生的事情时,也可以真正地为你模糊的东西——想想JSON卡在中间的条目将如何在你的应用程序访问日志中查看。
如果你想传递对象,你一定要使用请求的主体——还要注意Jackson(我看到你给它加了标签,所以我假设这就是你在Jersey中使用的)也必须知道如何反序列化该对象,否则你也会失败。正如@peeskillet所说,

@PathParam
,它将告诉您使用自定义类型参数的要求。Jersey不知道如何从字符串创建设备。但有一些方法可以让泽西知道如何创造它。请参阅javadoche@PathParam java doc,它只处理参数命名,而不处理从字符串到java对象的转换。我遵循了这个教程,我错过了什么?您没有读过关于静态fromString(String)
或valueOf(String)
方法或接受字符串的构造函数的内容吗?这些是您的设备
类的选项,如果您想将其用作@PathParam
的参数类型。您需要从传递给这三个选项中任意一个的字符串构造设备
,我将用谷歌搜索它。基本上,如果我想使用POST发送“设备”,我只能在消息正文中发送。对吗?如果您想将其作为@PathParam
,这意味着您想将JSON放在URL中。这并不常见,而且是个坏主意。因此,将它放在正文中阅读@PathParam
