Question

我在RouteConfig包中创建了一个app.config类，如下所示：

public class RouteConfig extends AbstractRouteConfig {
  @Override
  public void init(AppContext appContext) {

  route("/{controller}/{aut_id}/").to(AuthorsController.class).action("findById");
}

我创建了AppControllerConfig类：

package app.config;

import app.controllers.CatchAllFilter;
import app.controllers.api.v2.AuthorsController;
import org.javalite.activeweb.AbstractControllerConfig;
import org.javalite.activeweb.AppContext;
import org.javalite.activeweb.controller_filters.DBConnectionFilter;

public class AppControllerConfig extends AbstractControllerConfig {

    public void init(AppContext context) {
        add(new DBConnectionFilter(), new CatchAllFilter()).to(AuthorsController.class);
    }
}

我还定义了APIController类，如下所示：

package app.controllers;

import org.javalite.activeweb.AppController;

public abstract class APIController extends AppController {
    @Override
    protected String getContentType() {
        return "application/json";
    }

    @Override
    protected String getLayout() {
        return null;
    }

}

AuthorsController在app.controllers.api.v2包中：

import app.controllers.APIController;

import app.models.Author;

public class AuthorsController extends APIController {

    public void findById() {
        if (blank("aut_id")) {
            throw new RuntimeException("aut_id number is mandatory but was empty or null");
        } else {
            Author author = Author.findById(param("aut_id"));
            String jsonResponse = author.toJson(false);
            respond(jsonResponse);
        }
    }
}

尝试访问网址http://localhost:8080/api/v2/authors/9时，出现错误消息：

我做错了什么？我什至不输入AuthorsController ... 似乎它忽略了我的路线定义，并尝试找到以下内容：

"method":"GET","action":"9","error":"java.lang.NoSuchMethodException: app.controllers.api.v2.AuthorsController.9()

在同一控制器中声明index动作时，如下所示：

public void index() {
        final String json = Author.findFirst("AUT_ID = 9").toJson(false);
        respond(json);
    }

然后按http://localhost:8080/api/v2/authors即可。

这刷新了路由系统中的一个错误：https://github.com/javalite/activeweb/issues/397 该错误已修复，新快照已部署到Sonatype版本：2.3-SNAPSHOT。 https://oss.sonatype.org/content/repositories/snapshots/org/javalite/activeweb/2.3-SNAPSHOT/

您现在可以尝试查看是否可行。 BWT，感谢您的详细说明，它有助于建立正确的规格：RouterCustomSpec

最后，我弄清楚了如何使其工作。

我更改了RouteConfig类中的路由声明，如下所示：

route("/{controller}/find-by-id}/{id}").to(AuthorsController.class).action("findById");

我在findById中更改了AuthorsController方法，如下：

public void findById() {
        System.out.println(params());
        if (blank("id")) {
            throw new RuntimeException("autId number is mandatory but was empty or null");
        } else {
            Author author = Author.findById(param("id"));
            String jsonResponse = author.toJson(false);
            respond(jsonResponse);
        }
    }

按照惯例，以数字形式传递给url的参数名称被认为是id，除此之外没有其他内容，对吧？
