OOP编程iBatis 学习笔记之二 单表增删改操作

学习都是从简单到复杂，本例子是简单单表的增删改开始

Note.xml

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

<!DOCTYPE sqlMap PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"

"http://ibatis.apache.org/dtd/sql-map-2.dtd">

<sqlMap>

<typeAlias alias="Note" type="com.it.Note"/>

<select id="selectAllNote" resultClass="Note">

select *

</select>

<select id="selectNoteById"

parameterClass="int" resultClass="Note">

select sid,sname,major,birth from Note where sid=#sid#

</select>

<insert id="insertNote" parameterClass="Note">

insert into Note (

sid,

sname,

major,

birth

)

values(

#sid#,#sname#,#major#,#birth#)

</insert>

<update id ="updateNoteById" parameterClass="Note">

update note

set sname=#sname#,

major=#major#,

birth=#birth#

where sid=#sid#

</update>

<delete id="deleteNoteById" parameterClass="int">

Note.Java

package com.it;
import java.sql.Date;

public class Note {

private int sid=0;

private String sname=null;

private String major=null;

private Date birth=null;

private int book_oid;

public int getBook_oid() {
return book_oid;
}

public void setBook_oid(int bookOid) {
book_oid = bookOid;
}

public int getSid() {
return sid;
}

public void setSid(int sid) {
this.sid = sid;
}

public String getSname() {
return sname;
}

public void setSname(String sname) {
this.sname = sname;
}

public String getMajor() {
return major;
}

public void setMajor(String major) {
this.major = major;
}

public Date getBirth() {
return birth;
}

public void setBirth(Date birth) {
this.birth = birth;
}
}

记得在sqlMapConfig.xml中加如下语句

<sqlMap resource="com/it/Note.xml"/>

执行文件

package com.it;
