我无法将一个简单的参数从一个 Facelet 传递到另一个,并设置一个 bean 属性......这是我的代码:
调用页面,main.xhtml(仅相关代码):
<h:link outcome="index" value="disconnect" >
<f:param name="logout" value="true" />
</h:link>
最后一页index.xhtml:
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://xmlns.jcp.org/jsf/core">
<f:metadata>
<f:viewParam name="logout" value="#{indexBean.logout}"/>
<f:event type="preRenderView" listener="#{indexBean.redirect}" />
</f:metadata>
</html>
和IndexBean(仅相关代码):
@Named
@RequestScoped
public class IndexBean {
@Inject
private Logger logger;
private boolean logout;
public IndexBean() {this.logout = false;}
public void setLogout(boolean logout) {
logger.log(Level.DEBUG, "logout changed");
this.logout = logout;
}
public boolean isLogout() {return logout;}
public void redirect() throws IOException {
if(logout) {
//Never get in here
} else {
//Always here
}
}
}
我在链接(http://localhost/index.xhtml?logout=true)上获得了 URL 参数,但该setLogout
方法从未被调用。
我什至尝试将logout
类型更改为 String,正确更改 getter 和 setter,看看会发生什么,但从未调用过 setter...
任何想法?
提前致谢!!
