我写了一个自定义转换器，代码如下：
package tn.talan.testFramework.converter;
import java.util.ArrayList;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
import javax.faces.convert.FacesConverter;
import org.objectweb.salome_tmf.data.User;
import org.objectweb.salome_tmf.ihm.admin.AdministrationFinalOld;
@FacesConverter (value="userConverter")
public class UserConverter implements Converter {
@Override
public Object getAsObject(FacesContext context, UIComponent component, String value) {
User selectedUserfield = null;
ArrayList<User> usersList;
String userLogin;
System.out.println("converter getAsObject ");
AdministrationFinalOld administration=new AdministrationFinalOld();
administration.onInit();
usersList = administration.getAllUsers();
if (usersList!=null){
for(int i=0 ;i<usersList.size();i++)
{ selectedUserfield=usersList.get(i);
userLogin=selectedUserfield.getLoginFromModel();
if (userLogin.equals(value))
return usersList.get(i);
}
}
return null;
}
@Override
public String getAsString(FacesContext context, UIComponent component, Object value) {
System.out.println("converter getAsString "+value);
if (value==null) return "";
return ((User) value).getName();
}
这是我的面孔配置：
<?xml version="1.0"?>
<faces-config
version="2.0"
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">
<converter>
<converter-id>userConverter</converter-id>
<converter-class>tn.talan.testFramework.converter.UserConverter</converter-class>
</converter>
<converter>
<converter-id>projectConverter</converter-id>
<converter-class>tn.talan.testFramework.converter.ProjectConverter</converter-class>
</converter>
<converter>
<converter-id>URLCustomValidator</converter-id>
<converter-class>tn.talan.testFramework.converter.URLCustomValidator</converter-class>
</converter>
但是当我运行时出现此错误：
