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);	}}
