解决Spring框架的Dao层改用@Repository注解，无法使用JdbcDaoSupport的问题

解决Spring框架的Dao层改用@Repository注解，无法使用JdbcDaoSupport的问题

Alternatively, create an own implementation of JdbcDaoSupport class, and do whatever you want. Dive inside the source code of JdbcDaoSupport, it’s just a simple helper class to create a jdbcTemplate.

我创建了一个自己的类，扩展了JdbcDaoSupport类：

package demo1;

import javax.annotation.PostConstruct;
import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.support.JdbcDaoSupport;

public class JdbcDaoSupportExtend extends JdbcDaoSupport {

	@Autowired
	private DataSource dataSource;

	@PostConstruct
	public void initialize() {
		setDataSource(dataSource);
	}
}

在自己的Dao中继承了这个自己扩展的类：

package demo1;

import org.springframework.stereotype.Repository;

@Repository(value = "userDao")
public class UserDaoImpl extends JdbcDaoSupportExtend implements UserDaoI {

	@Override
	public void outMoney(Integer id, Double money) {
		getJdbcTemplate().update("update user set money = money - ? where id = ?", money, id);
	}

	@Override
	public void inMoney(Integer id, Double money) {
		getJdbcTemplate().update("update user set money = money + ? where id = ?", money, id);
	}
}
