问题描述
我正在GlassFish 3.1.2.2上使用JSF 2.2.4.
I am using JSF 2.2.4 on GlassFish 3.1.2.2.
我有这个后备豆:
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
import java.io.Serializable;
@ManagedBean(name="testMB")
@RequestScoped
public class TestMB implements Serializable {
public long id;
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
}
此视图test.xhtml:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">
<f:metadata>
<f:viewParam name="id" value="#{testMB.id}"/>
</f:metadata>
<h:body>
<h:inputText value="#{testMB.id}" />
</h:body>
</html>
当我打开/test.html?id=123时，ID显示为0而不是123. <f:viewParam>为什么不做它的工作?
When I open /test.html?id=123, then the ID shows up as 0 instead of 123. Why didn't <f:viewParam> do its job?
我安装了GlassFish 4.0.
I installed GlassFish 4.0.
JSF的Maven依赖项:
Maven dependencies for JSF:
<dependency>
<groupId>javax.faces</groupId>
<artifactId>javax.faces-api</artifactId>
<version>2.2</version>
</dependency>
faces-config.xml:
<?xml version='1.0' encoding='UTF-8'?>
<faces-config xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd"
version="2.2">
<!-- JSF and Spring are integrated -->
<application>
<el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
</application>
</faces-config>
和test.xhtml:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://xmlns.jcp.org/jsf/core"
xmlns:h="http://xmlns.jcp.org/jsf/html">
<f:metadata>
<f:viewParam name="id" value="#{testMB.id}"/>
</f:metadata>
<h:body>
<h:inputText value="#{testMB.id}" />
</h:body>
</html>
但是ID显示为0.
要测试的Maven项目: https://www.dropbox.com/s/qbc05vysspvt46l/jsf -spring-mybatis-master.zip
Maven project for test: https://www.dropbox.com/s/qbc05vysspvt46l/jsf-spring-mybatis-master.zip
推荐答案
问题已解决
以* .xhtml命名的页面.
Pages named as *.xhtml.
在web.xml中是:
In web.xml was:
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
右:
<url-pattern>*.xhtml</url-pattern>
