连接到Oracle 11g的数据源的bean配置是什么

Question

我的DAO课程如下

EmployeeDAOImpl.java

package com.shiladitya.emp.dao;

import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.RowMapper;
import org.springframework.stereotype.Repository;

import com.shiladitya.emp.bean.Employee;

@Repository(value="empDAO")
public class EmployeeDAOImpl implements EmployeeDAO{

    @Autowired
    private DataSource ds;
    private JdbcTemplate jdbcTemplate;

    public DataSource getDs() {
        return ds;
    }
    public void setDs(DataSource ds) {
        this.ds = ds;
    }
    public JdbcTemplate getJdbcTemplate() {
        return jdbcTemplate;
    }
    public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
        jdbcTemplate = new JdbcTemplate(this.getDs());
    }

    @Override
    public void createEmployeeTable() {
        String sql = "create table Employee (employeeId integer primary key, name varchar2(50), salary number(10,2));";
        jdbcTemplate.execute(sql);
    }

    @Override
    public void createEmployee(Employee employee) {
        String sql = "insert into Employee values(?,?,?)";
        jdbcTemplate.update(sql, new Object[] {employee.getEmployeeId(), employee.getName(), employee.getSalary()});
    }

    @SuppressWarnings({ "unchecked", "rawtypes" })
    @Override
    public List<Employee> selectAllEmployee() {
        String sql = "select * from Employee";
        List<Employee> listOfEmployee = new ArrayList<Employee>();

        listOfEmployee  = jdbcTemplate.query(sql, new RowMapper(){
            public Object mapRow(ResultSet rs, int rowNum) throws SQLException{
                Employee employee = new Employee();
                employee.setEmployeeId(rs.getInt("employeeId"));
                employee.setName(rs.getString("name"));
                employee.setSalary(rs.getDouble("salary"));

                return employee;
            }
        });

        return listOfEmployee;
    }

}

以下是配置文件 的 config.xml中

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <context:component-scan base-package="com.shiladitya.emp" />

    <bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"></bean>

    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"></property>
        <property name="url" value="jdbc:oracle:thin:@localhost:1521:XE"></property>
        <property name="username" value="system"></property>
        <property name="password" value="*******"></property>
    </bean>

</beans>

以下是我们创建bean并使用它们的主要应用程序

UI.java

package com.shiladitya.emp.ui;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.shiladitya.emp.bean.Employee;
import com.shiladitya.emp.dao.EmployeeDAOImpl;

public class UI {

    public static void main(String[] args) {
        @SuppressWarnings("resource")
        ApplicationContext context = new ClassPathXmlApplicationContext("config.xml");

        Employee employee = (Employee) context.getBean("employee");
        EmployeeDAOImpl edao = (EmployeeDAOImpl) context.getBean("empDAO");

        employee.setEmployeeId(1001);
        employee.setName("Shiladitya Kundu");
        employee.setSalary(24000.75);

        edao.createEmployeeTable();
        edao.createEmployee(employee);
    }

}

我得到了一个错误，如关注

请使用bean属性 jdbc瘦驱动程序为我提供如何连接 Oracle 11g Express Edition 数据库的解决方案？

请不要将问题标记为重复，因为我试图搜索所有相关问题，但无法找到任何解决方案。
