我正在慢慢地嘗試學習Spring Roo,但在爲我的應用程序生成查找程序時,它們已經開始鬆動。當在瀏覽器中呈現生成的菜單顯示取景器(鏈接)的存在,但是點擊鏈接,我立刻得到錯誤Spring Roo中的查找程序無法正常工作
HTTP Status 400 - Required Integer parameter 'population' is not present
type Status report
message Required Integer parameter 'population' is not present
description The request sent by the client was syntactically incorrect.
我有兩個gvNIX 1.4.0.RELEASE - Roo 1.3.1.RELEASE [rev 8cb81a3]
,並用普通Roo 1.3.1.RC1
(無gvnix嘗試加上)。
從數據庫結束我使用postgres 9.3。我的數據庫腳本來重現問題:
CREATE DATABASE world;
CREATE TABLE city
(
id integer NOT NULL,
name text NOT NULL,
countrycode character(3) NOT NULL,
district text NOT NULL,
population integer NOT NULL,
CONSTRAINT city_pkey PRIMARY KEY (id)
);
CREATE TABLE country
(
id integer NOT NULL DEFAULT nextval('hibernate_sequence'::regclass),
code character(3) NOT NULL,
name text NOT NULL,
continent text NOT NULL,
region text NOT NULL,
surfacearea real NOT NULL,
indepyear smallint,
population integer NOT NULL,
lifeexpectancy real,
gnp numeric(10,2),
gnpold numeric(10,2),
localname text NOT NULL,
governmentform text NOT NULL,
headofstate text,
capital integer,
code2 character(2) NOT NULL,
CONSTRAINT country_pkey PRIMARY KEY (id),
CONSTRAINT country_continent_check CHECK (continent = 'Asia'::text OR continent = 'Europe'::text OR continent = 'North America'::text OR continent = 'Africa'::text OR continent = 'Oceania'::text OR continent = 'Antarctica'::text OR continent = 'South America'::text)
);
CREATE TABLE countrylanguage
(
countrycode character(3) NOT NULL,
language text NOT NULL,
isofficial boolean NOT NULL,
percentage real NOT NULL,
CONSTRAINT countrylanguage_pkey PRIMARY KEY (countrycode, language)
);
我的袋鼠腳本如下follws:

後,我啓動應用程序。點擊人口查找城市的鏈接,我得到前面提到的錯誤,任何人都可以協助?我甚至不知道從哪裏開始調試......
您能否提供更多關於如何運行生成的應用程序的信息? Tomcat Maven插件使用'mvn tomcat:run'或'mvn tomcat7:run'? STS的Tomcat服務器? JBoss服務器?他們的哪個版本? – jcgarcia
感謝您的回覆。我使用STS的Tomcat 7服務器。即使我按照[教程] [(ttps://github.com/DISID/gvnix-samples/tree/master/quickstart-app#create-patterns-and-details-using-datatables))字樣,我也會收到此錯誤單詞,這兩個finder鏈接都不起作用,並且數據表中的編輯和刪除功能不起作用(URL變爲'http:// localhost:8080/petclinic/owners /'+ full.id +'?form&' ,而不是作爲參數傳遞的行索引,而是傳遞''+ full.id'' –
好的,我們知道您的問題的解決方案。幾分鐘後,我們將發佈一個答案與提供的解決方案。請,驗證答案,如果它適合你。關心。 – jcgarcia
