我是Play 2.0的新手.我创建了一个注册表单,现在我尝试创建一个搜索表单.但我被这个抓住了error: " Missing parameter in call definition: String In /home/thangnk/Task/conf/routes at line 17. ".

这是我的代码:

CONTROLLER --- Search.java

package controllers;

import java.util.ArrayList;
import java.util.List;

import models.Task;
import play.*;
import play.data.Form;
import play.db.ebean.Model.Finder;
import play.mvc.*;

import views.html.*;

public class Search extends Controller{
    static Form<Task> myform = form(Task.class);
    public static Result search(){
        return ok(search.render());
    }
    public static Result searchByusername(String username){
        Form<Task> filledForm = myform.bindFromRequest();
        username=filledForm.get().username;
        return ok(result_search.render(username));
    }   
}

MODELS --- Task.java

package models;

import java.util.*;

import javax.persistence.Entity;
import …

有我的配置：

 db.default.driver=com.mysql.jdbc.Driver
 db.default.url="jdbc:mysql:root:play2test" //Cannot connect to database [default] -> play mark this line
 db.default.user=root
 db.default.pass=123456

 db.default.driver="com.mysql.jdbc.Driver"
 db.default.url="jdbc:mysql:root:play2test" 
 db.default.user="root"
 db.default.pass="123456"
