模型类:Customer.java

-package com.shr.customer.model;

public class Customer {
int custId;
String name;
int age;

public Customer(int custId,String name,int age)
{
    this.custId=custId;
    this.name=name;
    this.age=age;
}

//getter and setter methods

public int getCustId() {
    return custId;
}
public void setCustId(int custId) {
    this.custId = custId;
}
public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public int getAge() {
    return age;
}
public void setAge(int age) {
    this.age = age;
}
}

接口(interface)类:CustomerDao

package com.shr.customer.dao;

import com.shr.customer.model.Customer;



public interface CustomerDAO {

public void insert(Customer customer);
public Customer findByCustomerId(int custId);

}

实现接口(interface)的类

package com.shr.customer.dao.impl;


import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import javax.sql.DataSource;
import com.shr.customer.dao.CustomerDAO;
import com.shr.customer.model.Customer;

public class JdbcCustomerDAO implements CustomerDAO
{
private DataSource dataSource;

public void setDataSource(DataSource dataSource) {
    this.dataSource = dataSource;
}

public void insert(Customer customer){

    String sql = "INSERT INTO CUSTOMER " +
            "(CUST_ID, NAME, AGE) VALUES (?, ?, ?)";
    Connection conn = null;

    try {
        conn = dataSource.getConnection();
        PreparedStatement ps = conn.prepareStatement(sql);
        ps.setInt(1, customer.getCustId());
        ps.setString(2, customer.getName());
        ps.setInt(3, customer.getAge());
        ps.executeUpdate();
        ps.close();

    } catch (SQLException e) {
        throw new RuntimeException(e);

    } finally {
        if (conn != null) {
            try {
                conn.close();
            } catch (SQLException e) {}
        }
    }
}

public Customer findByCustomerId(int custId){

    String sql = "SELECT * FROM CUSTOMER WHERE CUST_ID = ?";

    Connection conn = null;

    try {
        conn = dataSource.getConnection();
        PreparedStatement ps = conn.prepareStatement(sql);
        ps.setInt(1, custId);
        Customer customer = null;
        ResultSet rs = ps.executeQuery();
        if (rs.next()) {
            customer = new Customer(
                rs.getInt("CUST_ID"),
                rs.getString("NAME"), 
                rs.getInt("Age")
            );
        }
        rs.close();
        ps.close();
        return customer;
    } catch (SQLException e) {
        throw new RuntimeException(e);
    } finally {
        if (conn != null) {
            try {
            conn.close();
            } catch (SQLException e) {}
        }
    }
}
 }

最后是主类

package com.shr.common;


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

import com.shr.customer.dao.CustomerDAO;
import com.shr.customer.model.Customer;

public class App {

/**
 * @param args
 */
public static void main(String[] args) {
    // TODO Auto-generated method stub

    ApplicationContext context = 
            new ClassPathXmlApplicationContext("Spring-Module.xml");

        CustomerDAO customerDAO = (CustomerDAO) context.getBean("customerDAO");
        Customer customer = new Customer(1, "mkyong",28);
        customerDAO.insert(customer);

        Customer customer1 = customerDAO.findByCustomerId(1);
        System.out.println(customer1);
}

}

由于上述错误，我无法继续使用代码。请建议我如何解决它。

我用几个版本更改了 sql 的依赖项，但它仍然没有用。请告诉我我需要在 pom.xml 中添加哪些依赖项才能运行面向数据库的程序？

我正在使用 mysql 作为数据库。 我已经粘贴了整个代码，所以请检查是否还有其他错误。

最佳答案

pom 缺少 Spring-JDBC 模块

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-jdbc</artifactId>
        <version>${org.springframework-version}</version>
    </dependency>
