我无法让 JSF 注释正常工作。我花了一些时间试图弄清楚这一点。我正在使用 Maven + Tomcat7 + JSF2.16 + JDK1.7 + Spring 3 + Hibernate 4。如果我是新手，如果这很简单，请提前原谅我。

这是我的 pom.xml

我的 Faces 配置文件声明为 JSF 2，如下所示

    <?xml version="1.0" encoding="UTF-8"?>
    <faces-config
     xmlns="http://java.sun.com/xml/ns/javaee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee        http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
version="2.0">

我的托管 bean 注释如下

    @ManagedBean
    @ViewScoped
    public class TaskManagedBean implements Serializable {

private static final long serialVersionUID = 1L;
private static final String SUCCESS = "success";
private static final String ERROR   = "error";

//NOTE: Task Service is injected
@ManagedProperty(value="#{TaskService}")
TaskService taskService;

如果我像这样在 faces-config 中声明托管 bean

     <managed-bean>
       <managed-bean-name>taskManagedBean</managed-bean-name>
       <managed-bean-          class>com.uk.todolist.managed.bean.TaskManagedBean</managed-bean-class>
       <managed-bean-scope>session</managed-bean-scope>     
    </managed-bean>

这可行，但我不明白为什么注释不起作用。

任何帮助或方向，我将不胜感激！谢谢！

尝试将此添加到您的 spring 上下文 XML 配置文件中。

<context:component-scan base-package="your.base.package" />

它应该扫描您的课程以查找 bean。

我认为您不能对 bean 使用 JSF 注释。但也许我错了

我使用与您相同的技术，并且不使用 JSF 注释。我确实喜欢这样：

@Component
@Scope(value = "session")
public class TaskManagedBean implements Serializable {

private static final long serialVersionUID = 1L;
private static final String SUCCESS = "success";
private static final String ERROR   = "error";

//NOTE: Task Service is injected
@Autowired
TaskService taskService;

并且不要忘记像 Petter 所说的那样插入。

<context:component-scan base-package="your.base.package" />

您应该知道 Spring 中没有view作用域，您应该自己实现。但不要害怕有很多例子：https ://www.google.fr/search?sugexp=chrome,mod=7&sourceid=chrome&ie=UTF-8&q=spring+custom+viewscope
