我正在尝试将 Spring 3 与 JSF 2 一起使用，但我已经在执行以下操作时遇到了麻烦：

<h:outputText value="#{sampleController.hello}" />

使用静态值可以正常工作，但从 Java 获取值却不行（它不显示任何内容），例如

<body>
    Test <h:outputText value="#{sampleController.hello}" /> <h:outputText value="hello" />
</body>

会显示为

测试你好

样品控制器.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 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，这是针对 1.2 版本的。没有 servlet-mapping 工作！

<servlet-mapping>
    <servlet-name>facesServlet</servlet-name>
    <url-pattern>*.jsf</url-pattern>
</servlet-mapping>
