有了这个maven依赖，它就可以工作了：

    <dependency>
        <groupId>com.sun.faces</groupId>
        <artifactId>jsf-api</artifactId>
        <version>2.0.4-b09</version>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>com.sun.faces</groupId>
        <artifactId>jsf-impl</artifactId>
        <version>2.0.4-b09</version>
        <scope>compile</scope>
    </dependency>

但是有了这个，它就不起作用了：

    <dependency>
        <groupId>com.sun.faces</groupId>
        <artifactId>jsf-api</artifactId>
        <!--  or even this : <version>2.1.0-b09</version> -->
        <version>2.1.1-b02</version>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>com.sun.faces</groupId>
        <artifactId>jsf-impl</artifactId>
        <!--  or even this : <version>2.1.0-b09</version> -->
        <version>2.1.1-b02</version>
        <scope>compile</scope>
    </dependency>

除了

这是我的简单转换器类：

import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
import javax.faces.convert.FacesConverter;

@FacesConverter("heroConverter")
public class HeroBeanConverter implements Converter {

    public Object getAsObject(FacesContext context, UIComponent ui, String newValue) {
        System.out.println("getting as object");
        HeroBean hero = HeroBean.findHeroBeanByName(newValue);
        System.out.println("found hero : " + hero);
        return hero;
    }

    public String getAsString(FacesContext context, UIComponent component,
            Object value) {
        System.out.println("getting as string for value " + value);
        if (value == null) return "";
        return ((HeroBean) value).getName();
    }
}

这是一个错误，还是我在这里犯了一个错误？ :-D

Answer 1

这是一个错误。它与问题 1937 相关。此错误会导致非 Glassfish 容器上的 JSF 注释未被扫描，因为它们意外地包含了一些特定于 Glassfish 的注释扫描代码。

2.1.1-b02 也是一个开发版本。而是使用稳定的版本。最新的稳定版是 2.0.4-b09。
