Question

Answer 1

System.out.println(customer.getCustNo()+"=="+customer.getCustManagerName()+"===="+customer.getCustSatisfy()); 
这句也打出来了,也是对的,

Answer 2

at com.east.crm.dao.impl.CstCustomerDaoImpl.updateCustomer(CstCustomerDaoImpl.java:98) 
at com.east.crm.biz.CstCustomerBiz.updateCustomer(CstCustomerBiz.java:31) 
at com.east.crm.web.action.CstCustomerAction.updateCustomer(CstCustomerAction.java:148)
首先你注重看一下这里三个提示的地方，再就是可能最重要的问题是：
java.lang.IllegalArgumentException: Cannot invoke com.east.crm.entity.CstCustomer.setCstLinkmans - argument type mismatch提示是调用这个set方法出错类型不匹配，
还有你的两个实体类，是一对多的关系，把那两个类的代码和映射文件都贴出来，看一下

改了一这个,就对了,public boolean updateCustomer(CstCustomer customer)
throws Exception {
Session session = null;
Transaction tran = null;
int result = 0;
try {
session = HibernateUtils.getSession();
tran = session.beginTransaction();
CstCustomer customers = (CstCustomer) session.get(
CstCustomer.class, customer.getCustNo());
//不能用这个来做.
//BeanUtils.populate(customers, BeanUtils.describe(customer));
customers.setCustNo(customer.getCustNo());
customers.setCustName(customer.getCustName());
customers.setCustRegion(customer.getCustRegion());
customers.setCustManagerId(customer.getCustManagerId());
customers.setCustManagerName(customer.getCustManagerName());
customers.setCustLevel(customer.getCustLevel());
customers.setCustLevelLabel(customer.getCustLevelLabel());
customers.setCustSatisfy(customer.getCustSatisfy());
customers.setCustCredit(customer.getCustCredit());
customers.setCustAddr(customer.getCustAddr());
customers.setCustZip(customer.getCustZip());
customers.setCustTel(customer.getCustTel());
customers.setCustFax(customer.getCustFax());
customers.setCustWebsite(customer.getCustWebsite());
customers.setCustLicenceNo(customer.getCustLicenceNo());
customers.setCustChieftain(customer.getCustChieftain());
customers.setCustBankroll(customer.getCustBankroll());
customers.setCustTurnover(customer.getCustTurnover());
customers.setCustBank(customer.getCustBank());
customers.setCustBankAccount(customer.getCustBankAccount());
customers.setCustLocalTaxNo(customer.getCustLocalTaxNo());
customer.setCustNationalTaxNo(customer.getCustNationalTaxNo());
customers.setCustStatus(customer.getCustStatus());
customers.setCstActivities(customer.getCstActivities());
customers.setCstLinkmans(customer.getCstLinkmans());
customers.setCstServices(customer.getCstServices());

session.update(customers);
tran.commit();
result++;
} catch (Exception se) {
se.printStackTrace();
tran.rollback();
throw new SystemException("修改客户信息报异常！");
} finally {
HibernateUtils.closeSession(session);
}
return result > 0 ? true : false;
}
