FacesConverter不能與mojarra 2.1.0-b09，2.1.1-b02一起使用？

Question

有了這個Maven的依賴，它的工作原理：

<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>

但與此，它不工作：

<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> 

與

異常

這是我的簡單轉換器類：

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(); 
    } 
} 

它是一個錯誤，或者在這裏一個錯誤的IM？ :-D

Answer 1

這是一個錯誤。這與issue 1937有關。此錯誤導致JSF註釋未在非Glassfish容器上掃描，因爲它們意外地包含了一些Glassfish特定的註釋掃描代碼。

2.1.1-b02也是一個開發版本。而是使用穩定的版本。最新的穩定版是2.0.4-b09。
