Target Unreachable，标识符在JSF 2.2中解析为null [英] Target Unreachable, identifier resolved to null in JSF 2.2

问题描述

我在使用JSF 2.2和CDI时遇到问题，我的managerbean无法解决，并且出现此错误

I have a problem with JSF 2.2 and CDI, my managerbean is not solved and this error appear

"value ="#{userBean.user.name}:无法到达目标，标识符'userBean'解析为null"

"value="#{userBean.user.name}": Target Unreachable, identifier 'userBean' resolved to null"

这是我的经理bean.

This is my manager bean.

@ManagedBean
@RequestScoped
public class UserBean implements Serializable {
    private User user;

    public void setUser(user) {
        this.user = user;
    }
    ...
}

我的看法是:

<h:form id="login-form">
    <h:outputText value="User"/>
    <h:inputText value="#{userBean.user.name}" id="username"/>

    <h:outputText value="Senha"/>
    <h:inputSecret value="#{userBean.user.password}" id="pasword"/>

    <h:commandButton id="button" value="Login" action="#{userBean.login}"/>

    <h:messages />
</h:form>

推荐答案

我解决了这个问题.

我的Java版本是1.6，我发现它使用1.7和CDI，但是之后我将Java版本更改为1.7，并导入了包javax.faces.bean.ManagedBean，一切正常.

I solved this problem.

My Java version was the 1.6 and I found that was using 1.7 with CDI however after that I changed the Java version to 1.7 and import the package javax.faces.bean.ManagedBean and everything worked.
