业务层代码

package com.wzjpro.service.impl;

import java.util.List;

import javax.annotation.Resource;

import org.hibernate.criterion.DetachedCriteria;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

import com.wzjpro.dao.ICustomerDao;
import com.wzjpro.domain.Customer;
import com.wzjpro.service.ICustomerService;

/**
 * 客户的业务层实现类
 * @author Administrator

 */
@Service("customerService")
@Transactional(readOnly=true,propagation=Propagation.SUPPORTS)
public class CustomerServiceImpl implements ICustomerService {

    @Resource(name="customerDao")
    private ICustomerDao customerDao;

    @Override
    public List<Customer> findAllCustomer(DetachedCriteria dCriteria) {
        return customerDao.findAllCustomer(dCriteria);
    }

    @Override
    @Transactional(readOnly=false,propagation=Propagation.REQUIRED)
    public void saveCustomer(Customer customer) {
        customerDao.save(customer);
    }

}

Answer 1

  @Override
    @Transactional(readOnly=false,propagation=Propagation.REQUIRED)
    public void saveCustomer(Customer customer) {
        customerDao.save(customer);
    }
        这里去掉readOnly=false
        如下：
        @Transactional(propagation=Propagation.REQUIRED)
    public void saveCustomer(Customer customer) {
        customerDao.save(customer);
    }
