我得到“无法解决变量'indexController'”错误。

我的xhtml文件;

        </p:panel>

    </h:form>


</h:body>

我的控制器;

@Controller("indexController")
@Scope("session")
public class IndexController extends MainController {

private String name;

@Override
public void init() {
    //To change body of implemented methods use File | Settings | File Templates.
}

@Override
public void destroy() {
    //To change body of implemented methods use File | Settings | File Templates.
}

public void sayHello(String name){
    this.name = name;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}
}

我的applicationContext.xhtml文件;

你的问题是JSF通过CDI或ManagedBeans解析bean，而不是Spring管理的bean。

解决方案是为Spring beans配置EL名称解析器：

将它放在faces-config.xml

中

 <application>
   ...
   <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
 </application>

有关详细信息，请参阅Spring SpringBeanFacesELResolver javadocs。
