Question

我想用PrimeFaces，Spring和Hibernate开发我的应用程序，我采用这个例子，但确实有效。我不知道如何配置applicationContext.xml，web.xml，faces-config.xml，我不知道我是否错过了jar。

我有这个错误：

javax.el.PropertyNotFoundException：/index.xhtml @ 14,50 value =“＃{customer.lists}”：在类型上找不到属性“列表” comtic.scrum.managedBean.CustomerBean

我使用tomcat 7和JBoss Dev Studio，primeFaces 3.4.1，spring-3.2.0.RC1，hibernate-release-4.0.1.Final

我的表是客户（customerId，name，address，createdDate）列

Answer 1

是否真的有必要使用Spring / Hibernate / XML代码来演示问题？当只有一个XHTML文件和一个没有Spring / Hibernate / XML噪声的托管bean类时，你会遇到完全相同的问题。学习将问题分为1或2页。你的问题差不多有10页......

无论如何，你得到的例外

javax.el.PropertyNotFoundException：/index.xhtml @ 14,50 value =“＃{customer.lists}”：在comtic.scrum.managedBean.CustomerBean类型中找不到属性'列表'

只是试图告诉您CustomerBean类缺少getter方法getLists()。添加它并确保它返回List<Customer>。

public List<Customer> getLists() {
    return lists;
}

对于具体问题，

无关，属性名称中的复数s很奇怪。它只返回一个列表，对吗？如果我是你，我会用#{customer.list}吸气器将其重命名为getList()。
