Question

初学spring，在整合hibernate后，出现下面问题：我看了教程，是不是在applicationContext.xml中要配事务？

org.hibernate.QueryException: could not resolve property: serviceNum of: com.acc_charge.orm.AccCharge201010 [from com.acc_charge.orm.AccCharge201010 as model where model.serviceNum= ?]
程序代码：
在SearchFeeAction.java中调用
List list =accCharge2010DAO.findByProperty("serviceNum", teleID);

其中teleID通过表单提交.
serviceNum是AccCharge201010.java中的一个字段。
AccChargeDAO.java下的函数是自动生成的：
public List findByProperty(String propertyName, Object value) {log.debug("finding AccCharge201010 instance with property: "+ propertyName + ", value: " + value);
try {String queryString = "from AccCharge201010 as model where model."
+ propertyName + "= ?";
return getHibernateTemplate().find(queryString, value);
} catch (RuntimeException re) {log.error("find by property name failed", re);
throw re;}}
applicationContext.xml如下：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

Answer 1

一般只让他自动生成映射文件和实体类 DAO 自己写
List list =accCharge2010DAO.findByProperty("serviceNum", teleID);

serviceNum 找不到这个参数 不关事务的事
自动生成的类有时候需要改很多东西

Answer 2

检查在类和mapping文件中的属性名是否和你写的保持一致
另外检查此属性的getter 和setter方法是否是get/set加上“ServiceNum”

Answer 3

你还在这样设值啊？，怎么不用HIBERNATE自带的模板列？集成HIBERNATEDAOSUPPORT 里面有封装了的CRUD的方法，代码量大大减少了额！
