2.maven重點

< 3.事實
package entity;
/**

*/
public class PersonForExcel {
private String name;
private int age;
private String desc;
public PersonForExcel() {
super();
}
public PersonForExcel(String name, int age) {
this.name = name;
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getDesc() {
return desc;
}
public void setDesc(String desc) {
this.desc = desc;
}
public String toString() {
return "[name=" + name + ",age=" + age + ",desc=" + desc + "]";
}
}
4.配置
<?xml version="1.0" encoding="UTF-8" ?>
<kmodule xmlns="http://www.drools.org/xsd/kmodule">
<!--excel 決策表使用 -->
<kbase name="exceltest" packages="com.drools.excel.table.test1">
<ksession name="exceltest"/>
</kbase>
</kmodule>
5.測試
/**
* 測試點：決策表 先翻譯成drl 後執行
*/
@Test
public void excel1() {
// //把excel翻譯成drl檔案
SpreadsheetCompiler compiler = new SpreadsheetCompiler();
String drl = compiler.compile(ResourceFactory.newClassPathResource("com/drools/excel/table/test1/personAge.xlsx", "UTF-8"), "rule-table");
System.out.println(drl);
Long start = System.currentTimeMillis(); //執行決策表
try {
// load up the knowledge base
//
KieServices ks = KieServices.Factory.get();
KieContainer kContainer = ks.getKieClasspathContainer();
KieSession kSession = kContainer.newKieSession("exceltest");
PersonForExcel person = new PersonForExcel();
person.setName("Tony");
kSession.insert(person);
kSession.fireAllRules();
kSession.dispose();
} catch (Throwable t) {
t.printStackTrace();
}
System.out.println("COST:"+String.valueOf(System.currentTimeMillis()-start));
}
執行結果
package com.drools.excel.table.test1;
//generated from Decision Table
import entity.PersonForExcel;
function void printName(String name,String desc) {
System.out.println("name:"+name+" desc:"+ desc);
}
// rule values at B10, header at B5
rule "ageTest rule-table_10"
salience 1
when
person:PersonForExcel(age<=12)
then
person.setDesc("少年");
retract(person);
printName(person.getName(),person.getDesc());
end
// rule values at B11, header at B5
rule "ageTest rule-table_11"
salience 2
when
person:PersonForExcel(age>12, age<=24)
then
person.setDesc("青年");
retract(person);
printName(person.getName(),person.getDesc());
end
// rule values at B12, header at B5
rule "ageTest rule-table_12"
salience 3
when
person:PersonForExcel(age>24, age<=65)
then
person.setDesc("中年");
retract(person);
printName(person.getName(),person.getDesc());
end
// rule values at B13, header at B5
rule "ageTest rule-table_13"
salience 4
when
person:PersonForExcel(age>65)
then
person.setDesc("老年");
retract(person);
printName(person.getName(),person.getDesc());
end
name:Tony desc:少年

可以看到使用SpreadsheetCompiler可以將決策錶轉化成drl
