基于模板的简易代码生成器Python源码，需要写的单元测试太多，框架又是类似的，但类名和变量名却各不相同。索性花几分钟用Python脚本写个简易代码生成器，顺便记录于此，得空优化一下，以备后用。

代码

import os
import datetime

tplFilePath = 'E://template.java'
path = 'E://'

testObjList = ['Deposit',\
'Config',\
'FundsFilter',\
'MobileOpenAuth',\
'MobilePartnerRiskLevel',\
'MobilePhoneChargeOrder',\
'MobileSmspayValicode',\
'MobileSystemParam',\
'MobileVd',\
'Order',\
'OriginalOrder',\
'Package',\
'Plantform',\
'Seq',\
'Service',\
'TipsDelivery',\
'Trustlogin',\
'UpdateConfig',\
'UpdateHint',\
'UserAccount',\
'UserDao',\
'UserStatus'\
]

for testObj in testObjList:

testObjVarName = testObj[0].lower() + testObj[1:]

filename = 'Ibatis' + testObj +'DAOTester.java'
author = 'chenxin'

now = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')

tplFile = open(tplFilePath)
gFile = open(path+filename ,"w")

fileList = tplFile.readlines()

for fileLine in fileList:
line = fileLine.replace('${author}',author)\
.replace('${now}',now)\
.replace('${testObject}',testObj)\
.replace('${testObjVarName}',testObjVarName)
print line
gFile.writelines(line)

tplFile.close()
gFile.close()

模板

/**
* created since ${now}
*/
package com.alipay.mspcore.common.dal.ibatis;

import java.util.Date;

import junit.framework.Assert;

import com.alipay.mspcore.common.dal.daointerface.${testObject}DAO;
import com.alipay.mspcore.common.dal.dataobject.${testObject};
import com.alipay.sofa.runtime.test.AnnotatedAutowireSofaTestCase;
import com.iwallet.biz.common.util.money.Money;

/**
* @author ${author}
* @version $Id: Ibatis${testObject}DAOTester.java, v 0.1 ${now} ${author} Exp $
*/
public class Ibatis${testObject}DAOTester extends AnnotatedAutowireSofaTestCase {

@Override
public String[] getConfigurationLocations() {
return new String[] { "META-INF/spring/common-dal-db.xml",
"META-INF/spring/mobilespcore-common-dal-dao.xml", "META-INF/spring/common-dal.xml" };
}

@Override
public String[] getResourceFilterNames() {
return new String[] { "META-INF/spring/common-dal-db.xml" };
}

@Override
public String[] getWebServiceConfigurationLocations() {
return new String[] {};
}

private ${testObject}DAO get${testObject}DAO() {
${testObject}DAO dao = (${testObject}DAO) this.getBean("${testObjVarName}DAO", ${testObject}DAO.class, null);
return dao;
}

public void test${testObject}DAO() {
${testObject}DAO configDAO = get${testObject}DAO();
Assert.assertNotNull(configDAO);
}

public void test() {
${testObject}DO ${testObjVarName}DO = new ${testObject}DO();
${testObjVarName}DO.setGmtCreate(new Date());
${testObjVarName}DO.setGmtModified(new Date());
${testObjVarName}DO.setId(10000);

${testObject}DAO ${testObjVarName}DAO = get${testObject}DAO();
long result = ${testObjVarName}DAO.insert(${testObjVarName}DO);
Assert.assertTrue(result > 0);
}
}

效果

/**

*/
package com.alipay.mspcore.common.dal.ibatis;

import java.util.Date;

import junit.framework.Assert;
