DeltaRelease--Java Web增量发布工具（附源码）

DeltaRelease，Java Web 增量发布工具，又称增量更新打包工具，是指在Java Web应用程序用来发布补丁包的一种工具。因增量发布具有风险小，更新速度快等优势，在企业Java Web应用发布补丁时所广泛使用。本着有福同享的奉献精神，小编将这款好用的工具免费送给大家。

Java Web增量发布工具的源码已经发布到GitHub，有需要的小伙伴们可以猛击这里查看。

1.publish_config.xml配置文件，配置补丁文件的源位置及发布位置

<?xml version="1.0" encoding="UTF-8"?>
<config>
<apps default="favsoft" patchFolder="d:/favsoft/patchFolder">
<app appName="deltaRelease" patchFile="deltaReleaseFile.txt">
<patch_source_dir>
E:\work\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp2\webapps\DeltaRelease
</patch_source_dir>
<patch_dest_dir>
/opt/apache-tomcat-7.0.28/webapps/DeltaRelease
</patch_dest_dir>
</app>
</apps>
</config>

2.PublishService.java，发布服务类，获取编译好的补丁文件，发布到目标位置。

package com.favccxx.favsoft.deltarelease;

import java.io.File;
import java.io.IOException;
import java.util.Iterator;
import java.util.List;

import org.apache.commons.configuration.HierarchicalConfiguration;
import org.apache.commons.io.FileUtils;
import org.apache.commons.lang.StringUtils;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

public class PublishService {

private static Logger logger = LogManager.getLogger(PublishService.class.getName());

public static void getDeltaReleaseFiles(){

String sourceFolder = SystemConfig.getInstance().getString("apps[@default]");
String patchFolder = SystemConfig.getInstance().getString("apps[@patchFolder]");
try {
//清理输出文件目录
File file = new File(patchFolder);
if(file.exists()){
FileUtils.cleanDirectory(new File(patchFolder));
}
FileUtils.forceMkdir(new File(patchFolder));
} catch (IOException e) {
logger.error("Error get File, The wrong file path is:" + patchFolder);
logger.error("Error Message is:" + e.getMessage());
}

//取出最新的class列表
List<HierarchicalConfiguration> appList = SystemConfig.getInstance().configurationsAt("apps.app");
for (Iterator<HierarchicalConfiguration> iterator = appList.iterator(); iterator.hasNext();) {
HierarchicalConfiguration hierarchicalConfiguration = iterator.next();
String appName = hierarchicalConfiguration.getString("[@appName]");
String patchFilePath = hierarchicalConfiguration.getString("[@patchFile]");
String patch_source_dir = hierarchicalConfiguration.getString("patch_source_dir");
String patch_dest_dir = hierarchicalConfiguration.getString("patch_dest_dir");
String destDir = patchFolder + patch_dest_dir;
//执行拷贝补丁文件
copyPatchFile(appName,patch_source_dir,patchFilePath,destDir);
}

}

private static void copyPatchFile(String appName,String sourceDir, String patchFilePath, String destDir){
logger.info("******************************开始拷贝"+ appName +"工程的补丁文件**************************");
try {
//创建生成补丁文件的目录
FileUtils.forceMkdir(new File(destDir));
} catch (IOException e) {
logger.error("Error get destDir,The wrong path is:" + destDir);
logger.error("Error Message is:" + e.getMessage());
}

File patchFile = new File(Thread.currentThread().getContextClassLoader().getResource(PublishConstants.SYSTEM_CONFIG_DIR+patchFilePath).getFile());	//读取补丁文件--deltaReleaseFile.txt
try {
List fileLines = FileUtils.readLines(patchFile);
int count=0;
for (Iterator iterator = fileLines.iterator(); iterator.hasNext();) {
String fileName = (String) iterator.next();
if(StringUtils.isNotEmpty(fileName)){
if(fileName.endsWith("java")){
//java补丁文件,需找到对应的class
fileName = fileName.replaceAll(".java", ".class");
String sourceFilePath = sourceDir + "\\WEB-INF\\classes" + fileName;
File compileFile = new File(sourceFilePath);
if(compileFile.exists()){
String destFilePath = destDir + "\\WEB-INF\\classes" + fileName;
FileUtils.copyFile(compileFile, new File(destFilePath));
logger.info("-------" + ++count +"成功拷贝补丁文件到：" + destFilePath);
}else{
logger.error("未找到该补丁文件，错误的路径：" + sourceFilePath);
}

}else{
//JSP、CSS、JS等格式的文件直接copy到工程的目录
String sourceFilePath = sourceDir + fileName;
String destFilePath = destDir + fileName;
FileUtils.copyFile(new File(sourceFilePath), new File(destFilePath));
logger.info("-------" + ++count +"成功拷贝补丁文件到：" + destFilePath);
}
}
}
logger.info("******************************"+ appName +"工程补丁文件获取成功，共拷贝"+ count +"个补丁文件**************************");
} catch (IOException e) {
logger.error("Error in execute copyPatchFile. The wrong message is:" + e.getMessage());
}

}

}
