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
