我正在FormComponentPanel为Wicket 建立一个定制.这是在自己的Maven项目中完成的.该项目后来作为依赖项添加到我的webapp中.目前,我的自定义面板不包含额外功能.我在同一个包里面有以下文件(在src/main/java/package下).
CustomFormPanel.java:
class CustomFormPanel extends FormComponentPanel<String> {
public CustomFormPanel(final String id) {
super(id);
}
}
CustomFormPanel.html:
<wicket:panel>
</wicket:panel>
我使用这个组件如下:
CustomPage.java:
public class CustomPage extends WebPage {
private final StatelessForm<Void> form;
private FormComponentPanel<String> customPanel;
public CustomPage(final PageParameters params) {
super(params);
customPanel = new CustomFormPanel("customPanel");
form = new StatelessForm<Void>("form") {
@Override
public void onSubmit() {
final String param = customPanel.getModelObject();
}
};
}
@Override
public void onInitialize() {
super.onInitialize();
form.add(customPanel);
add(form);
}
}
CustomPage.html:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:wicket="http://wicket.apache.org">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>
<body>
<form wicket:id="form">
<wicket:container wicket:id="customPanel"></wicket:container>
<input type="submit" value="Job erstellen" />
</form>
</body>
</html>
如果我在浏览器中导航到此站点,则会收到以下错误消息:
Last cause: Failed to find markup file associated. CustomFormPanel: [CustomFormPanel [Component id = customPanel]]
您必须src/main/java在pom.xml中将该文件夹声明为资源文件夹.
<resources>
<resource>
<filtering>false</filtering>
<directory>src/main/resources</directory>
</resource>
<resource>
<filtering>false</filtering>
<directory>src/main/java</directory>
<includes>
<include>**</include>
</includes>
<excludes>
<exclude>**/*.java</exclude>
</excludes>
</resource>
</resources>
因此,位于.java文件旁边的资源将添加到构建中.
