Question

我已将primefaces-3.4RC1.jar添加到WEB-INF/lib目录中。在我的控制器中我自动装配我的模型bean，如

@ManagedBean
@RequestScoped
public class MyController{

@Autowired
Location loc;

//other stuff

}

我的Location课程类似于

public class Location{     
    private Integer countryId;
    //getters setters
}

我的观点看起来像

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:p="http://primefaces.org/ui">
    <div class="contentBox cornerBorder border">

    <p:dialog>
    <table class="DialogTable">                                                     
    <tr>
     <td><label>Country</label></td> 
        <h:selectOneMenu required="true" id="contry" styleClass="text-box" value="#{myController.loc.countryId}">   
    ----------------------------------------------------------------------------------------------^here it gives warning and if i run it crashes 

    </tr>
    </table>
    </p:dialog>

当我点击链接打开对话框时，会抛出错误，找不到属性countryId。如果我删除value="myController.loc.countryId"它运行正常... 任何指导我正确方向的人

P.S：我已在应用程序context.xml

中创建了相应的条目

实际错误

严重：javax.el.PropertyNotFoundException： /WebPages/personal/personalDiv.xhtml @ 230,119 value =“＃{myController.loc.countryId}”：该类 'com.deltasoft.controller.myController'没有该属性 'LOC'。

您可能希望像这样更改代码。

@ManagedBean
@RequestScoped
public class MyController{

@ManagedProperty
private Location loc;   // Getters and Setters.

//other stuff

}

和

@component
public class Location{     
    private Integer countryId;
    //getters setters
}

并在你的spring.xml中你应该做

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:security="http://www.springframework.org/schema/security"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

 <context:component-scan="path to Location class path"/>
</beans>

PrimeFaces 3.4 RC1，对话框无法识别Managed Bean属性
