原因是引入包出错：

在UserDAOImpl中使用

public void setDataSource(DataSource dataSource){
    		this.jdbcTemplate=new JdbcTemplate(dataSource);
    		this.namedParameterJdbc=new NamedParameterJdbcTemplate(dataSource);
    		this.simpleJdbcTemplate=new SimpleJdbcTemplate(dataSource);
    	}

引入DataSource类出错：

import sun.jdbc.odbc.ee.DataSource;

正确的应该是：  
import javax.sql.DataSource;
