转换--连接字符串和计算器
目录
一、流程
concat fields和计算器是转换里面的，本次以这两个为列讲述转换里面的东西，还是从ktr分析开始。
观察concat fields节点，其实就是将firstName和lastName连接起来，并赋值给name这个字段，
计算器就是定义新字段，选择计算方式，指定需要计算的列，
明白界面怎么配置后，就知道该设置哪些属性，该怎么看ktr文件，该怎么写代码，关于spoon工具的讲解，B站有很多。
我看的就是下面这个，还是很透彻的。2019kettle8.2最新教程_哔哩哔哩_bilibili2019kettle8.2最新教程

二、代码说明
这篇就不分析ktr文件了，之前两篇对ktr里面哪些元素应该知道怎么看了。
在代码后面标注了是从ktr哪个节点知道设置的代码。
定义下面四个获取Meta获取，重点说明ConcatFieldMeta和CalculatorMeta，
/*
1. Excel输入
*/
ExcelInputMeta inputMeta = getInputMeta();
/*
2. concat fields节点
*/
ConcatFieldsMeta concatFieldsMeta = getConcatFieldsMeta();
/*
3. 计算器节点
*/
CalculatorMeta calculatorMeta = getCalculatorMeta();
/*
4. excel输出
*/
ExcelOutputMeta outputMeta = getOutputMeta();ConcatFieldsMeta
最好的解释就是代码注释，
/**

* @return
*/
private ConcatFieldsMeta getConcatFieldsMeta(){
ConcatFieldsMeta concatFieldsMeta = new ConcatFieldsMeta(); //<type>ConcatFields</type>
//设置连接分割符

textFileFields[0] = new TextFileField();
textFileFields[0].setName("firstName");
textFileFields[0].setType(ValueMetaInterface.TYPE_NONE);
textFileFields[0].setLength(-1); // <fields> --> <field> --> <length>-1</length>
/*

</field>
*/
textFileFields[1] = new TextFileField();
textFileFields[1].setName("lastName"); // <name>lastName</name>
textFileFields[1].setType(ValueMetaInterface.TYPE_NONE); // <type>None</type>
textFileFields[1].setLength(-1); // <fields> --> <field> --> <length>-1</length>
concatFieldsMeta.setOutputFields(textFileFields);
//设置目标字段
/*
<ConcatFields>
<targetFieldName>name</targetFieldName>
<targetFieldLength>0</targetFieldLength>
<removeSelectedFields>N</removeSelectedFields>
</ConcatFields>
*/
concatFieldsMeta.setTargetFieldName("name"); // <targetFieldName>name</targetFieldName>
concatFieldsMeta.setTargetFieldLength(0); // <targetFieldLength>0</targetFieldLength>
concatFieldsMeta.setRemoveSelectedFields(false);// <removeSelectedFields>N</removeSelectedFields>
return concatFieldsMeta;
}class ConcatFieldsMeta extends TextFileOutputMetaConcatFieldsMeta继承了TextFileOutputMeta，所以其实是一个文本输出Meta。
CalculatorMeta
这是计算器节点的Meta，仿照计算器的节点配置图片产生的代码如下，下面是选择的三种计算方式，
其中 Quarter of Date A 是用于计算birthday这个时间格式，是属于哪个季度；
Day of week of date A 是此日期A是星期几，周日算第一天；
A * B 就比较明显了 字段A 乘以 字段B 得到一个新值，那么A，B就必须是数字类型才行，否则报错。
/**
* 获取计算器
* @return
*/
private CalculatorMeta getCalculatorMeta(){
CalculatorMeta calculatorMeta = new CalculatorMeta(); // <type>Calculator</type>
CalculatorMetaFunction[] metaFunctions = new CalculatorMetaFunction[3];
metaFunctions[0] = new CalculatorMetaFunction();
metaFunctions[0].setFieldName("quarter"); // <field_name>quarter</field_name>
metaFunctions[0].setCalcType(CalculatorMetaFunction.CALC_QUARTER_OF_DATE);// <calc_type>QUARTER_OF_DATE</calc_type>
metaFunctions[0].setFieldA("birthday"); // <field_a>birthday</field_a>
metaFunctions[0].setValueType(ValueMetaInterface.TYPE_NONE); // <value_type>None</value_type>
metaFunctions[0].setRemovedFromResult(false); // <remove>N</remove>
metaFunctions[1] = new CalculatorMetaFunction();
metaFunctions[1].setFieldName("week_of_day");
metaFunctions[1].setCalcType(CalculatorMetaFunction.CALC_DAY_OF_WEEK);
metaFunctions[1].setFieldA("birthday");
metaFunctions[1].setValueType(ValueMetaInterface.TYPE_NONE);
metaFunctions[1].setRemovedFromResult(false);
metaFunctions[2] = new CalculatorMetaFunction();
metaFunctions[2].setFieldName("account");
metaFunctions[2].setCalcType(CalculatorMetaFunction.CALC_MULTIPLY);
metaFunctions[2].setFieldA("working_life");
metaFunctions[2].setFieldB("yearly_salary");
metaFunctions[2].setValueType(ValueMetaInterface.TYPE_NONE);
metaFunctions[2].setRemovedFromResult(false);
calculatorMeta.setCalculation(metaFunctions);
return calculatorMeta;
}当上述concat fields和计算器节点代码好了以后，那么剩下的就是把节点串联在一起。

}三、问题项
写这个交换案例时，只碰到一个问题，但这个问题真是让人头大，看了好久直到不得已跟踪源码才发现是少设置了一个length属性。
如下图所示，name只有一个连接符，和想象中压根不一样，firstName和lastName压根没有连接在一起。
而ktr文件在spoon中运行后，name的值是firstName和lastName的连接，比如 liu-wei，刘-大壮。
明白下面三个类的作用后，那么看代码自然是看ConcatFields这个类了。
此ConcatFields类的简略如下，包含ConcatFieldsMeta和ConcatFieldsData，其中processRow()方法是主要用来处理交换过程的，每一个交换节点都是如此。
public class ConcatFields extends TextFileOutput implements StepInterface {
private static Class<?> PKG = ConcatFields.class; // for i18n purposes, needed by Translator2!!
public ConcatFieldsMeta meta;
public ConcatFieldsData data;
public ConcatFields( StepMeta stepMeta, StepDataInterface stepDataInterface, int copyNr, TransMeta transMeta,
Trans trans ) {
super( stepMeta, stepDataInterface, copyNr, transMeta, trans ); // allocate TextFileOutput
}
@Override
public synchronized boolean processRow( StepMetaInterface smi, StepDataInterface sdi ) throws KettleException {
meta = (ConcatFieldsMeta) smi;
data = (ConcatFieldsData) sdi;
Object[] r = getRow(); // This also waits for a row to be finished.
return result;
}
}跟踪processRow这个方法，终于在TextFileOutput中找到了真相，在这个类中有一个方法，把String转变为binary，然后这里面有length的判断，在下面代码注释已经说明了原因，
private byte[] convertStringToBinaryString( ValueMetaInterface v, String string ) throws KettleValueException {
int length = v.getLength(); // 由于没有设置length，所以int默认为0
//string.length()为大于0的值，所以进入此分支
if ( length > -1 && length < string.length() ) {
//所以此处 string.substring(0,0)
String tmp = string.substring( 0, length );
}
}所以tmp是一个空字符串，自然也没有后面连接什么事了，“”-“” 这种在Excel中就是一个 - 。
解决方式：
textFileFields[1].setLength(-1); // <fields> --> <field> --> <length>-1</length>四、运行
