Spring+JPA整合问题

Question

再做项目之前的将Spring与JPA的整合后，在测试Spring容器是否加载成功时，会报如下错误：严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.context.annotation.internalPersistenceAnnotationProcessor': Initialization of bean failed; nested exception is org.springframework.beans.InvalidPropertyException: Invalid property 'order' of bean class [org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor]: No property 'order' found

请问这是怎么回事啊？会不会是引入的jar包不对的问题？？？谢谢大家的回答~~~~
非常感谢~~~~

Answer 1

Invalid property 'order' of bean class 你去看一下是不是某个 Entity 中的 order 属性没有 get/set 方法？由于框架所采用的是 JavaBeans 规范，JavaBeans 规范是通过 get/set 方法来寻找属性的。

Answer 2

不是的~~~~我现在只是先把框架搭好，项目里面没有任何的类！！！只建立了一个单元测试类
@Test
public void runTest(){
      ApplicationContext cxt = new ClassPathXmlApplicationContext("beans.xml");
}
用junit执行。看是否能成功运行，就包如上错误了beans.xml内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

   <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">

   </bean>

Answer 3

也有可能是你别的项目的错误
建议把tomcat 下的webapps别的无关的部署文件删除

Answer 4

也不是~~~~~还是没用啊！！！大家在帮帮我啊~~~~~有没有可能是jar包？
再次感谢~~~

Answer 5

你加载spring文件的时候 ContextLoaderListener 这个类有没有写错
 org.springframework.beans.InvalidPropertyException: Invalid property 'order' of bean class 
你在spring文件里配置的时候 配置order这个属性的字段类型配置错误 ，它不能转换所以报这个错误了

Answer 6

就没配置任何字段，只是搭个框架就这问题！我也觉得是jar包问题，大家帮我看看有啥问题没？
