phpBatis组件

用过java开源项目mybatis(ibatis)后，觉得它的思路挺好，于是做了一个风格类似于batis的组件。

将SQL从MVC中的模型中分离出来，一方面便于后期SQL的优化，也让PHP不再夹杂着SQL，让PHPer更专注于业务逻辑。

下面是demo

一、主配置文件config.xml(名字任意)

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

<configuration>
	<!-- 全局别名 -->
	<typeAliases>
		<typeAlias key="DAOPATH" value="application/"/>
	</typeAliases>
	
	<!-- 数据源 -->
    <databases>
    	<database id="sysvotes" default="true">
    		<property name="driver" value="pdo"/>
    		<property name="charset" value="UTF8"/>
    		<property name="dsn" value="mysql:host=localhost;dbname=test"/>
    		<property name="username" value="root"/>
    		<property name="password" value=""/>
    	</database>
    	
    	<database id="syshotels">
    		<property name="driver" value="pdo"/>
    		<property name="dsn" value="mysql:host=192.168.1.251;dbname=syshotels"/>
    		<property name="username" value="root"/>
    		<property name="password" value=""/>
    	</database>
    </databases>
    
    <caches>
	    <cache id="memcache" default="true">
	    	<property name="type" value="memcache"/>
	    	<property name="host" value="localhost"/>
	    	<property name="port" value="11211"/>
	    </cache>
	    
	    <cache id="file">
	    	<property name="type" value="file"/>
	    	<property name="filepath" value="Cache/Temp/"/>
	    </cache>
    </caches>
</configuration>

二、mapper文件log.xml

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

<mapper>
	<sql id="allFields">`TIMESTAMP`, logger, `LEVEL`, message, thread, `FILE`, line</sql>
	
	<!-- 
	id:作为Batis引用的唯一标识
	resultClass:返回数据的封装为Class对象。若没有此参数，将不会对结果封装为对象
	cacheId:缓存配置标签ID。目前支持：file、memcache
	cacheTime:缓存超时时间，单位秒
	cahce:是否缓存,默认false
	prepare:是否使用PDO的prepare,默认true
	 -->
	<select id="SelectAll" resultClass="Log" cacheId="file" cacheTime="3600" cache="true" prepare="true">
		SELECT
		#allFields#
		FROM
		log2
		WHERE
		thread > :number
	</select>
	
	<!--
	对于复杂的搜索条件，phpBatis不支持if-else或trim这样的标签。 
	解决方法：关闭使用PDO的prepare绑定，将搜索条件在PHP中处理好，然后传给phpBatis直接替换。
	 -->
	<select id="getLogs" cache="false" prepare="false">
		SELECT
		#allFields#
		FROM
		log2
		WHERE
		:terms
	</select>

	<insert id="insertlog">
		insert into log2
		(#allFields#)
		values
		(:timestamp, :logger, :level, :message, :thread, :file, :line)
	</insert>

	<update id="Update" parameterClass="Person">
		update log2 set
		logger = :logger,
		message = :message,
		thread = :thread,
		line = :line
		where `timestamp`=:timestamp
	</update>

	<delete id="Delete" parameterClass="int">
		delete from PERSON
		where PER_ID = #value#
	</delete>

</mapper>

三、调用phpBatis的测试文件test.php

<?php
require 'phpBatis.php';

$batis = new PhpBatis('application/config.xml');

/**
 * 事务
 */
$time = time();
$params = array(
	'timestamp'=>$time,
	'logger'=>'Mr.jinyong',
	'level'	=>'WARN',
	'message'=>'test',
	'thread' =>'5501',
	'file'	=> __FILE__,
	'line'	=>50
);
$batis->beginTransaction();
try{
	$batis->setMapper("application/log.xml")->insert("insertlog", $params);
	
	$updateParams = array(
		'timestamp'=>$time,
		'logger'=>'Mr.jinyong',
		'message'=>'update',
		'thread' =>'5501',
		'line'	=>50
	);
	$batis->setMapper("application/log.xml")->update("Update", $updateParams);
	$batis->setMapper("application/log.xml")->insert("insertlog", $params);
	
	$batis->commitTransaction();
}catch(BatisException $e){
	$batis->rollBackTransaction();
}
// /**
// * 插入一条记录
// */
// $params = array(
// 	'timestamp'=>time(),
// 	'logger'=>'Mr.jinyong',
// 	'level'	=>'WARN',
// 	'message'=>'test',
// 	'thread' =>'5501',
// 	'file'	=> __FILE__,
// 	'line'	=>50
// );
// $batis->setMapper("application/log.xml")->insert("insertlog", $params);


// /**
// * 更新一条记录
// */
// $batis->setMapper("application/log.xml")->update("Update", $params);

// /**
// * 查询一条记录,并返回Log对象
// */
// $result = $batis->setMapper("application/log.xml")->queryOne("SelectAll", array(':number'=> 0));
// echo $result->getLogger();

// /**
//  * 复杂的查询条件，关闭prepare
//  */
// $result = $batis->setMapper("application/log.xml")->queryList("getLogs", array(':terms'=> "thread=5400 OR thread<3000"));
// print_r($result);
