kettle源码下载
⑴ 如何使用kettle源码更改spoon的东西
1.2. 编译源码
将项目加载到eclipse
将kettle项目拷贝到eclipse的workspace目录下，在eclipse中新建java project，项目名称和你拷贝过来的kettle文件夹名称一致
项目导入到eclipse中会出现一个错误，如下图，将这个文件的源码全部注释掉
编译
打开build.xml, 在右边的。Outline 点击kettle->run as ->ant build
第一次编译的时候需要从网上下载几个文件，放在C:\Documents and Settings\Administrator\.subfloor，网络不好的话下载会比较慢，也可以直接文件放在C:\Documents and Settings\Administrator\下。编译完成后将bin目录下的.bat文件拷贝到Kettle目录下点击Spoon.bat运行，运行成功代表编译已近通过
用源码运行Spoon
Kettle源码工程本身可能是在linux64位机器上调试的，swt配置是linux64的库，所有在运行源码前需要修改成win32的swt，步骤如下：工程à属性àJava Build Pathàlibrariesàadd jars
然后将linux64的SWT库删除
最后打开src-uiàorg.pentaho.di.ui.spoonàSpoon.java， Run As àjava application
二．源码分析
2.1. 修改kettle界面
修改初始化界面
打开package org.pentaho.di.ui.spoon的Spoon.Java，找到main函数，该main函数为Spoon工具的入口，找到如下语句
Splash splash = new Splash(display);
该语句为spoon初始化显示的界面，跳到定义Splash.java，下面函数
canvas.addPaintListener(new PaintListener() {
publicvoid paintControl(PaintEvent e) {
String versionText = BaseMessages.getString(PKG, "SplashDialog.Version") + " " + Const.VERSION; //$NON-NLS-1$ //$NON-NLS-2$
StringBuilder sb = new StringBuilder();
String line = null;
try {
BufferedReader reader = new BufferedReader(newInputStreamReader(Splash.class.getClassLoader().getResourceAsStream("org/pentaho/di/ui/core/dialog/license/license.txt")));//$NON-NLS-1$
while((line = reader.readLine()) != null) {
sb.append(line + System.getProperty("line.separator")); //$NON-NLS-1$
}
} catch (Exception ex) {
sb.append(""); //$NON-NLS-1$
Log.warn(BaseMessages.getString(PKG, "SplashDialog.LicenseTextNotFound")); //$NON-NLS-1$
}
String licenseText = sb.toString();
e.gc.drawImage(kettle_image, 0, 0);
// If this is a Milestone or RC release, warn the user
if (Const.RELEASE.equals(Const.ReleaseType.MILESTONE)) {
versionText = BaseMessages.getString(PKG, "SplashDialog.DeveloperRelease") + " - " + versionText; //$NON-NLS-1$ //$NON-NLS-2$
drawVersionWarning(e);
} elseif (Const.RELEASE.equals(Const.ReleaseType.RELEASE_CANDIDATE)) {
versionText = BaseMessages.getString(PKG, "SplashDialog.ReleaseCandidate") + " - " + versionText; //$NON-NLS-1$//$NON-NLS-2$
}
elseif (Const.RELEASE.equals(Const.ReleaseType.PREVIEW)) {
versionText = BaseMessages.getString(PKG, "SplashDialog.PreviewRelease") + " - " + versionText; //$NON-NLS-1$//$NON-NLS-2$
}
elseif (Const.RELEASE.equals(Const.ReleaseType.GA)) {
versionText = BaseMessages.getString(PKG, "SplashDialog.GA") + " - " + versionText; //$NON-NLS-1$//$NON-NLS-2$
}
Font verFont = new Font(e.display, "Helvetica", 11, SWT.BOLD); //$NON-NLS-1$
e.gc.setFont(verFont);
e.gc.drawText(versionText, 290, 205, true);
// try using the desired font size for the license text
int fontSize = 8;
Font licFont = new Font(e.display, "Helvetica", fontSize, SWT.NORMAL); //$NON-NLS-1$
e.gc.setFont(licFont);
// if the text will not fit the allowed space
while (!willLicenseTextFit(licenseText, e.gc)) {
fontSize--;
licFont = new Font(e.display, "Helvetica", fontSize, SWT.NORMAL); //$NON-NLS-1$
e.gc.setFont(licFont);
}
e.gc.drawText(licenseText, 290, 290, true);
}
});
1. 修改背景图片
找到ui/image/下面的kettle_splash.png，替换该图片
2. 修改版本信息
找到e.gc.drawText(versionText, 290, 205, true); 改为e.gc.drawText("海康威视数据交换平台V1.0", 290, 205, true);
3. 修改下面的描述性文字
找到e.gc.drawText(licenseText, 290, 290, true);改为e.gc.drawText("作者：海康", 290, 290, true);

⑵ kettle源码搭建运行时出现错误
将安装包pdi-ce-5.4.0.1-130\data-integration\ui目录下的所有文件拷贝到源码包pentaho-kettle-5.4.0.1-R\ui目录下，即可解决~~
⑶ 我看到你关于kettle不释放内存的回答，想要一下你改完后org.pentaho.di.core.logging.LoggingRegistr源码
你留个邮箱或者qq吧 网络hi怎么发文件我还不怎么清楚
