[英]JSF 2 + Spring 3 can't access bean
我正在尝试将Spring 3与JSF 2一起使用,但是我在执行以下操作时遇到了麻烦:
<h:outputText value="#{sampleController.hello}" />
使用静态值可以很好地工作,但是从Java获取值不会(它不会显示任何内容),例如
<body>
Test <h:outputText value="#{sampleController.hello}" /> <h:outputText value="hello" />
</body>
会显示为
测试你好
SampleController.java:
@Component
@Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS)
public class SampleController {
private String hello = "Hello!";
public String getHello() {
return hello;
}
public void setHello(String hello) {
this.hello = hello;
}
}
我使用了Mkyong的“ JSF 2 + Spring 3 Integration”进行项目配置( http://www.mkyong.com/jsf2/jsf-2-0-spring-integration-example/ )

删除servlet-mapping jsf,这是1.2版本。 没有servlet映射的作品!
