如何将变量传递给以下方法

@Path("/entry-point")
public class EntryPoint
{
    private final Logger logger = Logger.getLogger(EntryPoint.class);

    @GET
    @Path("test")
    public Response test(@PathParam("param") String param)
    {
        logger.info("Received message " + param);
        String output = "Hi : " + param;
        return Response.status(200).entity(output).build();
    }

    @GET
    @Path("/{test2}")
    public String test2(@PathParam("param") String param)
    {
        logger.info("Received message " + param);
        return "yo";
    }
}

以下网址为参数

提供了空输出

http://localhost:8080/entry-point/test/ = hi null http://localhost:8080/entry-point/test/value = 404错误

感谢

您必须路由请求。因此，例如，如果我想要达到测试方法，这就是我需要做的路由

http://localhost:8080/entry-point/test/thisIsTheStringPARAM

网址的'thisIsTheStringPARAM'部分已被检索 '@PathParam（“param”）'并分配给String param。

查看下面的代码我也做了一些更改。

@Path("/entry-point")
public class EntryPoint
{
    private final Logger logger = Logger.getLogger(EntryPoint.class);

    @GET
    @Path("/test/{param}")
    public Response test(@PathParam("param") String param)
    {
        logger.info("Received message " + param);
        String output = "Hi : " + param;
        return Response.status(200).entity(output).build();
    }

    @GET
    @Path("/test2/{param}")
    public String test2(@PathParam("param") String param)
    {
        logger.info("Received message " + param);
        return "yo";
    }
}
