iBatis示例程序

纯粹是为了感受一下JavaEye非常好的代码格式化功能。
这样格式化得太漂亮了。

根据iBatis包中的示例程序修改。
com.mydomain.domain包中
1. Account.java

package com.mydomain.domain;

public class Account {
    private int id;
    private String firstName;
    private String lastName;
    private String emailAddress;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public String getEmailAddress() {
        return emailAddress;
    }

    public void setEmailAddress(String emailAddress) {
        this.emailAddress = emailAddress;
    }

    @Override
    public String toString() {
        return "id: " + this.getId() + "\nfirstName: " + this.getFirstName()
                + "\nlastName: " + this.getLastName() + "\nemailAddress: "
                + this.getEmailAddress() + "\n";
    }
}

com.mydomain.data包中
2. Account.xml

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

</sqlMap>

3. sqlMapConfig.xml

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

6. createDB.sql - MySQL

create table(
	ACC_ID bigint,
	ACC_FIRST_NAME varchar(20),
	ACC_LAST_NAME varchar(20),
	ACC_EMAIL varchar(30)
);

2 楼 leiqing2002 2013-05-02  

create table Account (
acc_id int,
acc_first_name varchar(20),
acc_last_name varchar(20),
acc_email varchar(30)
);
应该添加创建的表名吧

不错,增删改查都有了,麻雀虽小，五脏具全
