ibatis的自动生成插件：ibator

搭建iBatis 开发环境：

1 、导入相关的jar 包，ibatis-2.3.0.677.jar 、mysql-connector-java-5.1.6-bin.jar

2 、编写配置文件：Jdbc 连接的属性文件 ;总配置文件， SqlMapConfig.xml 关于每个实体的映射文件（Map 文件）

Demo ：

model层

package com.ccssoft.model;

import java.io.Serializable; import java.util.Date;

@SuppressWarnings("unused") public class User implements Serializable { private Integer userID; private String accountNo; private String password; private String name; private String phone; private String email;

public Integer getUserID() { return userID; } public void setUserID(Integer userID) { this.userID = userID; } public String getAccountNo() { return accountNo; } public void setAccountNo(String accountNo) { this.accountNo = accountNo; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public String getPhone() { return phone; } public void setPhone(String phone) { this.phone = phone; } public String toString(){ return "phone ="+phone+";"; } }

SqlMap.properties ：

jdbc.driver=oracle.jdbc.driver.OracleDriver
jdbc.url=jdbc\:oracle\:thin\:@127.0.0.1\:1521\:dream
jdbc.username=dream
jdbc.password=marconi

User_Map.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="User" type="com.ccssoft.demo.entity.User" /> <resultMap id="userMap" class="User"> <result property="userID" column="USERID"/> <result property="accountNo" column="ACCOUNTNO"/> <result property="password" column="password"/> <result property="name" column="name"/> <result property="email" column="email"/> <result property="phone" column="phone"/> </resultMap>

<insert id="addUser" parameterClass="User"> insert into t_user( USERID,ACCOUNTNO,password, name,email,phone ) values( id_seq.nextval,#accountNo#,#password#, #name#,#email#,#phone# ) </insert>  <delete id="deleteUserById" parameterClass="Integer"> delete from t_user where USERID=#userID# </delete>  <update id="updateUser" parameterClass="User"> update t_user set name=#name#,email=#email#,phone=#phone#,password=#password# where USERID=#userID# </update>

<select id="selectAllUser" parameterClass="HashMap" resultClass="User"> select t.USERID,t.ACCOUNTNO,t.password, t.name,t.email,t.phone from (select t.*,ROWNUM RN from t_user t where 1=1 <isNotEmpty property="accountNo"> and ACCOUNTNO like ‘%$accountNo$%‘ </isNotEmpty> <isNotEmpty property="name"> and name like ‘%$name$%‘ </isNotEmpty> ) t where RN>#start# and RN<=#end#

</select>

<select id="selectUserById" parameterClass="Integer" resultClass="User"> select * from t_user where USERID=#userID# </select>

select t.USERID,t.ACCOUNTNO,t.password, t.name,t.email,t.phone from (select t.*,ROWNUM RN from t_user t) t where t.name like ‘%$name$%‘ and RN>#start# and RN<=#end# </select> <select id="selectUsersByAccountNo" parameterClass="HashMap" resultClass="HashMap"> select t.USERID,t.ACCOUNTNO,t.password, t.name,t.email,t.phone from (select t.*,ROWNUM RN from t_user t) t where RN>#start# and RN<=#end# and t.ACCOUNTNO like ‘%$accountNo$%‘ </select> <select id="selectUsersByName_No" parameterClass="HashMap" resultClass="HashMap"> select t.USERID,t.ACCOUNTNO,t.password, t.name,t.email,t.phone from (select t.*,ROWNUM RN from t_user t) t where RN>#start# and RN<=#end# and (t.name like ‘%$name$%‘ or ACCOUNTNO like ‘%$accountNo$%‘)

</select> <select id="selectUserByNo" parameterClass="String" resultClass="User"> select * from t_user where ACCOUNTNO=#accountNo# </select> <select id="selectPwdByNo" parameterClass="String" resultClass="String"> select password from t_user where ACCOUNTNO=#accountNo# </select>

<select id="selectUserCount" parameterClass="User" resultClass="Integer"> select count(*) from t_user where 1=1 <isNotEmpty property="accountNo"> and ACCOUNTNO like ‘%$accountNo$%‘ </isNotEmpty> <isNotEmpty property="name"> and name like ‘%$name$%‘ </isNotEmpty> </select>

</sqlMap>

说明：

如果xml 中没有ibatis 的提示，则window --> Preference--> XML-->XML Catalog---> 点击add

选择uri URI: 请选择本地文件系统上

iBatisDemo1/WebContent/WEB-INF/lib/sql-map-config-2.dtd 文件；

Key Type: 选择Schema Location；

Key: 需要联网的，不建议使用；

SqlMapConfig.xml ：

<?xmlversion="1.0"encoding="UTF-8"?>
<!DOCTYPE sqlMapConfig PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"
"http://ibatis.apache.org/dtd/sql-map-config-2.dtd">

<transactionManagertype="JDBC">

<propertyname="JDBC.Username"value="${username}"/>
<propertyname="JDBC.Password"value="${password}"/>
</dataSource>
</transactionManager>
<sqlMapresource="com/iflytek/entity/Student.xml"/>
</sqlMapConfig>

StudentDao ：

package com.iflytek.dao;

StudentDaoImpl ：

}

TestIbatis.java ：

package com.iflytek.test;
