Drools7.4.1教程（5）-workbench规则开发与测试

drools,是由JBOSS公司开源的一套基于JAVA的规则引擎系统

规则进行时

假设我们现在要做一个考试评分的规则，60-70分以上为及格，70-90分以上良好，90-100分为优秀

1. 新建数据对象
   由于其实规则项目就是一个maven项目，所以我们先新建一个软件包,再建立一个数据对象

   package com.myteam.demo.entity;
   
   /**
    * This class was automatically generated by the data modeler tool.
    */
   
   @javax.persistence.Entity
   public class ScoreRule implements java.io.Serializable {
   
       static final long serialVersionUID = 1L;
   
       @javax.persistence.GeneratedValue(generator = "SCORERULE_ID_GENERATOR", strategy = javax.persistence.GenerationType.AUTO)
       @javax.persistence.Id
       @javax.persistence.SequenceGenerator(name = "SCORERULE_ID_GENERATOR", sequenceName = "SCORERULE_ID_SEQ")
           private java.lang.Long id;
   
           //分数
           private int score;
   
           //结果
           private String result;
   
           public ScoreRule() {
           }
   
           public ScoreRule(java.lang.Long id) {
               this.id = id;
           }
   
           public java.lang.Long getId() {
               return this.id;
           }
   
           public void setId(java.lang.Long id) {
               this.id = id;
           }
   
           public int getScore() {
               return score;
           }
   
           public void setScore(int score) {
               this.score = score;
           }
   
           public String getResult() {
               return result;
           }
   
           public void setResult(String result) {
               this.result = result;
           }
   }

2. 再建立一个规则，直接贴代码

       package com.myteam.demo.rules;
   
   import com.myteam.demo.entity.ScoreRule;
   
   no-loop
   
   rule "excellent"
       when 
           s:ScoreRule(score>=90&&score<=100)
       then
           System.out.println("excellent");
           modify(s) { setResult("excellent") };
   end
   
   
   rule "good"
       when 
           s:ScoreRule(score>=70&&score<90)
       then
           System.out.println("good");
           modify(s) { setResult("good") };
   end
   
   
   rule "pass"
       when 
           s:ScoreRule(score>=60&&score<70)
       then
           System.out.println("pass");
           modify(s) { setResult("pass") };
   end
   
   rule "nopass"
       when 
           s:ScoreRule(score<60)
       then
           System.out.println("nopass");
           modify(s) { setResult("nopass") };
   end

3. 新建一个测试场景
   
   

如果大家觉得好，哈哈，可以给我点鼓励，谢谢大家。
