urule决策引擎可简化开发校验、决策类代码，底层由java语言实现，可基于springboot快速配置，因为urule工具目前为非常用工具，网上关于springboot整合urule资料匮乏，一直自己摸索，简单的环境搭建也费了些功夫，遇到些坑，作此记录

本次记录主要记录urule-serve端urule-client端分开部署的模式，这种使用场景也会更多；嵌入式成一个项目的配置和urule-server端一致。

一、urule-server端：

1.1、基于maven的springboot基本环境搭建请参考springboot教程

1.2、引入urule相关依赖，urule-console-pro，开源版本可到

中心搜索，依赖如下：

<dependencies>
  <dependency>
   <groupid>org.springframework.boot</groupid>
   <artifactid>spring-boot-starter-web</artifactid>
  </dependency>
  <dependency>
   <groupid>com.bstek.urule</groupid>
   <artifactid>urule-console-pro</artifactid>
   <version>2.1.0</version>
   <exclusions>
    <exclusion>
     <groupid>org.slf4j</groupid>
     <artifactid>slf4j-jdk14</artifactid>
    </exclusion>
   </exclusions>
  </dependency>
  <dependency>
   <groupid>javax.servlet</groupid>
   <artifactid>servlet-api</artifactid>
   <version>2.5</version>
   <scope>provided</scope>
  </dependency>
  <dependency>
   <groupid>org.mybatis.spring.boot</groupid>
   <artifactid>mybatis-spring-boot-starter</artifactid>
   <version>1.3.1</version>
  </dependency>
  <dependency>
   <groupid>com.alibaba</groupid>
   <artifactid>druid</artifactid>
   <version>1.0.9</version>
  </dependency>
  <dependency>
   <groupid>mysql</groupid>
   <artifactid>mysql-connector-java</artifactid>
  </dependency>
 </dependencies>

1.3、配置文件：两个，appplication.yml , application.properties

appplication.yml，配置数据库信息（我们把urule项目存到数据库中）

server:
 port: 8081
spring:
 application:
 name: uruleserver
 datasource:
 name: datasource
 jdbc-url: jdbc:mysql://127.0.0.1:3306/urule?useunicode=true&characterencoding=utf-8
 username: root
 password: 666666
 # 使用druid数据源
 type: com.alibaba.druid.pool.druiddatasource
 driver-class-name: com.mysql.jdbc.driver
 filters: stat
 maxactive: 20
 initialsize: 1
 maxwait: 60000
 minidle: 1
 timebetweenevictionrunsmillis: 60000
 minevictableidletimemillis: 300000
 validationquery: select 'x'
 testwhileidle: true
 testonborrow: false
 testonreturn: false
 poolpreparedstatements: true
 maxopenpreparedstatements: 20

注意，我这此刻datasource下不jdbc-url而不是url。根据springboot版本自行调整

application.properties,配置项目储存位置

#若为本地环境需配置此路径
#urule.repository.dir=f:/eclipsepractice/03_springcloud/repo4rule
#若为数据库，配置此项，两项均不配则系统指定默认地址
urule.repository.databasetype=mysql
urule.repository.datasourcename=datasource
ignore-unresolvable=true
order=1

1.4、初始化bean

datesource

@configuration
public class configuration {
 @bean
 public propertysourcesplaceholderconfigurer propertysourceloader() {
  propertysourcesplaceholderconfigurer configurer = new propertysourcesplaceholderconfigurer();
  configurer.setignoreunresolvableplaceholders(true);
  configurer.setorder(1);
  return configurer;
 }
 
  @bean
  @configurationproperties(prefix = "spring.datasource")
  public datasource datasource() {
   return datasourcebuilder.create().build();
  }
}

serverlet

@component
public class uruleservletregistration
{
 @bean
 public servletregistrationbean<httpservlet> registeruruleservlet()
 {
 return new servletregistrationbean(new uruleservlet(), new string[] { "/urule/*" });
 }
 }

1.5、启动类：

@springbootapplication
@importresource({"classpath:urule-console-context.xml"})
public class application
{
 public static void main(string[] args)
 {
 springapplication.run(application.class, args);
 }
}

二、客户端调用：

2.1、配置类

application.yml
server:
 port: 8090
spring:
 application:
 name: uruleclient
 datasource:
 name: datasource
 url: jdbc:mysql://127.0.0.1:3306/myland?useunicode=true&characterencoding=utf-8
 username: root
 password: 666666
 # 使用druid数据源
 type: com.alibaba.druid.pool.druiddatasource
 driver-class-name: com.mysql.jdbc.driver
 filters: stat
 maxactive: 20
 initialsize: 1
 maxwait: 60000
 minidle: 1
 timebetweenevictionrunsmillis: 60000
 minevictableidletimemillis: 300000
 validationquery: select 'x'
 testwhileidle: true
 testonborrow: false
 testonreturn: false
 poolpreparedstatements: true
 maxopenpreparedstatements: 20
urule:
 ###服务端发现地址
 resporityserverurl: http://localhost:8081
 ###knowledgeupdatecycle为0时，不是检查缓存，每次都从服务端拉取，为1时，会先查找缓存
 knowledgeupdatecycle: 1

2.2、初始化bean

@configuration
public class ruleconfig {
 @bean
 public propertysourcesplaceholderconfigurer propertysourceloader() {
  propertysourcesplaceholderconfigurer configurer = new propertysourcesplaceholderconfigurer();
  configurer.setignoreunresolvableplaceholders(true);
  configurer.setorder(1);
  return configurer;
 }
}

@component
public class uruleservletregistration {
 //此servlet用于接收urule服务端发布的知识包，使用开源版本时删除或者注释这个bean
 @bean
 public servletregistrationbean registeruruleservlet(){
  return new servletregistrationbean(new knowledgepackagereceiverservlet(),"/knowledgepackagereceiver");
 }
}

2.3、controller:

@restcontroller
public class testcontroller {
@requestmapping("/rule")
 public string getrara(@requestparam string data)throws ioexception{
   knowledgeservice knowledgeservice = (knowledgeservice) utils.getapplicationcontext().getbean(knowledgeservice.bean_id);
//参数，urule项目名/知识包名
   knowledgepackage knowledgepackage = knowledgeservice.getknowledge("letasa/pare");
   knowledgesession session = knowledgesessionfactory.newknowledgesession(knowledgepackage);
   integer integer = integer.valueof(data);
   map<string, object> param = new hashmap();
//参数，var，传入参数，和参数库中定义一致
   param.put("var", integer);
   session.firerules(param);
//result，返回参数，和参数库中定义一致
   integer result = (integer) session.getparameter("result");
   return string.valueof(result);
 }
}

2.4、启动类

@springbootapplication
@importresource({"classpath:urule-core-context.xml"})
public class application {
 public static void main(string[] args) {
  springapplication.run(application.class, args);
 }
}
