spring4集成hibernate3：xml方式

 

model：

package com.lzj.www.model;


public class User {

	private Integer id;
	private String name;
	
	public Integer getId() {
		return id;
	}
	
	public void setId(Integer id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}
	
}

 model.hbm.xml:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
	"-//Hibernate/Hibernate Mapping DTD 3.0//EN"

	</class>
	
</hibernate-mapping>

 service:

package com.lzj.www.service.impl;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.lzj.www.model.User;
import com.lzj.www.service.UserService;


public class UserServiceImpl extends HibernateDaoSupport implements UserService{

	@Override
	public void addUser(User user) {
		this.getHibernateTemplate().save(user);
	}	
	
}

 可能出现的错误：

 

 1、nullpointException
this.getHibernateTemplate()为null，原因是使用Template的对象是直接new出来的，spring并没有
对其进行注入，因此该对象是不具有sessionFactory的，也没有绑定相关的事务
所以要把这个对象配置到ioc容器中

2、java.lang.IllegalArgumentException
 Pointcut is not well-formed: expecting '(' at character position 0
在配置aop的advisor时，配置的是pointcut-ref而不是pointcut，用快捷键的时候小心点就是了
