我是 Spring roo 的新手(我正在为 jquery、bootstrap 和 databale 使用 gvnix spring roo 发行版)。我在 mysql 中创建了 3 个表
CREATE TABLE `categories` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`Category_Name` varchar(50) NOT NULL,
`Description` varchar(50) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;
insert into `categories`(`id`,`Category_Name`,`Description`) values (1,'Facility','facility'),(2,'Ikare','Ikare');
CREATE TABLE `subcategories` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`subcategory_name` varchar(50) NOT NULL,
`category_id` int(11) NOT NULL,
PRIMARY KEY (`id`),
KEY `FK_md1atoxe8wd8bi2fhf9nnw4q0` (`category_id`),
CONSTRAINT `FK_md1atoxe8wd8bi2fhf9nnw4q0` FOREIGN KEY (`category_id`) REFERENCES `categories` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8;
insert into `subcategories`(`id`,`subcategory_name`,`category_id`) values (1,'room service',1),(2,'store',1),(3,'server setup',2),(4,'Travel not working',2);
并使用数据库逆向工程命令创建 bean 文件。
并使用了脚手架、jquery、bootstrap 和 dattable
现在将应用程序部署到 tomcat7 后,我可以创建类别、子类别。
我的问题是在创建新服务台时,该类别显示在下拉列表中,所有子类别都默认显示。但是我希望当我选择特定类别时,它应该显示相应的子类别,但不是所有类别的所有子类别。
而且验证不起作用意味着如果我没有在必填字段中输入任何内容,我就可以保存数据。
下面是我创建新服务的代码。
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<div xmlns:c="http://java.sun.com/jsp/jstl/core" xmlns:field="urn:jsptagdir:/WEB-INF/tags/jquery/form/fields" xmlns:form="urn:jsptagdir:/WEB-INF/tags/datatables" xmlns:jsp="http://java.sun.com/JSP/Page" xmlns:spring="http://www.springframework.org/tags" version="2.0">
<jsp:directive.page contentType="text/html;charset=UTF-8"/>
<jsp:output omit-xml-declaration="yes"/>
<form:create id="fc_com_arat_roo_domain_ServiceDesk" modelAttribute="serviceDesk" path="/servicedesks" render="${empty dependencies}" z="5rY4NJcP8nJ/t0tXbZs8XZLebzs=">
<field:select field="categoryId" id="c_com_arat_roo_domain_ServiceDesk_categoryId" itemValue="id" items="${categorieses}" path="/categorieses" z="eTrZa7tDsB6IOgAA143b/eECzgs="/>
<field:select field="subcategoryId" id="c_com_arat_roo_domain_ServiceDesk_subcategoryId" itemValue="id" items="${subcategorieses}" path="/subcategorieses" z="WLOZ5uG2O8vxZDxYu7Gg1q0Zx9w="/>
<field:input field="comment" id="c_com_arat_roo_domain_ServiceDesk_comment" required="true" z="h/4gHQSwuY162Ci8qehagMY7ZUY="/>
</form:create>
<form:dependency dependencies="${dependencies}" id="d_com_arat_roo_domain_ServiceDesk" render="${not empty dependencies}" z="zpBtjtNE7E7oXm/3C5Dw9BagNsM="/>
</div>
控制器如下:
@RequestMapping(params = "form", produces = "text/html")
public String createForm(Model uiModel) {
populateEditForm(uiModel, new ServiceDesk());
return "servicedesks/create";
}
void populateEditForm(Model uiModel, ServiceDesk serviceDesk) {
uiModel.addAttribute("serviceDesk", serviceDesk);
uiModel.addAttribute("categorieses", Categories.findAllCategorieses());
uiModel.addAttribute("subcategorieses", Subcategories.findAllSubcategorieses());
}
下面是我使用的命令的 log.roo。

你能帮我解决这个问题吗?
