drools规则引擎与kie-wb和kie-server远程执行规则（7.18.0.Final）
最近研究了一下规则引擎drools。
这篇博客带你搭建并运行一个可在线编辑，在线打包，远程执行的规则引擎（drools）
本篇博客同时参考https://blog.csdn.net/chinrui/article/details/79018351 博客内容
1、搭建Workbench （首先保证主机联网，有docker环境）
docker run -p 8080:8080 -p 8001:8001 -d --name drools-wb jboss/drools-workbench-showcase:latest
容器启动完之后就可以访问如下链接（可能docker镜像下载有点慢。可以切换阿里云镜像仓库）
http://IP:8080/business-central/kie-wb.jsp?locale=zh_CN
界面如下：
用户名：admin 密码：admin
登录进去之后
点击创建工程
点击创建Add Asset
创建完对象点击保存
保存之后回到工程界面
继续创建rule,向导性规则
package com.myspace.mytest1; rule "myrule1" dialect "java" when $info : mytestmodel1( sex == 0 ) then $info.setName( "李雷" ); end
创建测试场景
编辑如下测试规则
然后返回点击build
然后点击
2、创建 kie-server
docker run -p 8180:8080 -d --name kie-server --link drools-wb:kie_wb jboss/kie-server-showcase:latest
运行如上docker容器
容器运行起来之后
访问如下链接http://IP:8180/kie-server/services/rest/server/
在访问链接 http://IP:8180/kie-server/services/rest/server/containers
这里发现已经有了我们刚才创建的kie-server服务列表，这是我们需要创建一个运行容器，返回我们的mytest1rule
发布成功之后
然后在访问链接http://IP:8180/kie-server/services/rest/server/containers
接下来上代码开发我们的测试程序
maven项目引用依赖
<properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> <drools.version>7.18.0.Final</drools.version> </properties> <dependencies> <dependency> <groupId>org.drools</groupId> <artifactId>drools-core</artifactId> <version>${drools.version}</version> </dependency> <dependency> <groupId>org.drools</groupId> <artifactId>drools-compiler</artifactId> <version>${drools.version}</version> </dependency> <dependency> <groupId>org.drools</groupId> <artifactId>drools-decisiontables</artifactId> <version>${drools.version}</version> </dependency> <dependency> <groupId>org.drools</groupId> <artifactId>drools-templates</artifactId> <version>${drools.version}</version> </dependency> <dependency> <groupId>org.kie</groupId> <artifactId>kie-api</artifactId> <version>${drools.version}</version> </dependency> <dependency> <groupId>org.kie.server</groupId> <artifactId>kie-server-client</artifactId> <version>${drools.version}</version> </dependency> </dependencies>
实体类
package com.myspace.mytest1; /** * This class was automatically generated by the data modeler tool. */ public class mytestmodel1 implements java.io.Serializable { static final long serialVersionUID = 1L; private java.lang.Integer id; private java.lang.String name; private java.lang.Integer sex; public mytestmodel1() { } public java.lang.Integer getId() { return this.id; } public void setId(java.lang.Integer id) { this.id = id; } public java.lang.String getName() { return this.name; } public void setName(java.lang.String name) { this.name = name; } public java.lang.Integer getSex() { return this.sex; } public void setSex(java.lang.Integer sex) { this.sex = sex; } public mytestmodel1(java.lang.Integer id, java.lang.String name, java.lang.Integer sex) { this.id = id; this.name = name; this.sex = sex; } @Override public String toString() { return "mytestmodel1 [id=" + id + ", name=" + name + ", sex=" + sex + "]"; } }
控制台执行代码
package com.myspace.mytest1; import java.io.IOException; import java.util.LinkedList; import java.util.List; import org.kie.api.KieServices; import org.kie.api.command.Command; import org.kie.api.command.KieCommands; import org.kie.api.runtime.ExecutionResults; import org.kie.server.api.marshalling.MarshallingFormat; import org.kie.server.api.model.ServiceResponse; import org.kie.server.client.KieServicesClient; import org.kie.server.client.KieServicesConfiguration; import org.kie.server.client.KieServicesFactory; import org.kie.server.client.RuleServicesClient; public class droolstest { public static final String SERVER_URL = "http://ip:8180/kie-server/services/rest/server"; public static final String PASSWORD = "kieserver1!"; public static final String USERNAME = "kieserver"; public static final String KIE_CONTAINER_ID = "mytest1_1.0.0-SNAPSHOT"; public static final String KIE_SESSION_ID = "mytest1"; public static void main(String[] args) throws IOException { // KisService 配置信息设置 KieServicesConfiguration kieServicesConfiguration = KieServicesFactory.newRestConfiguration(SERVER_URL, USERNAME, PASSWORD, 10000L); kieServicesConfiguration.setMarshallingFormat(MarshallingFormat.JSON); // 创建规则服务客户端 KieServicesClient kieServicesClient = KieServicesFactory.newKieServicesClient(kieServicesConfiguration); RuleServicesClient ruleServicesClient = kieServicesClient.getServicesClient(RuleServicesClient.class); // 规则输入条件 mytestmodel1 mytest = new mytestmodel1(); mytest.setSex(1); // 命令定义，包含插入数据，执行规则 KieCommands kieCommands = KieServices.Factory.get().getCommands(); List<Command<?>> commands = new LinkedList<>(); commands.add(kieCommands.newInsert(mytest, "mytestmodel1")); commands.add(kieCommands.newFireAllRules()); ServiceResponse<ExecutionResults> results = ruleServicesClient.executeCommandsWithResults(KIE_CONTAINER_ID, kieCommands.newBatchExecution(commands, KIE_SESSION_ID)); // 返回值读取 mytestmodel1 value = (mytestmodel1) results.getResult().getValue("mytestmodel1"); System.out.println(value.toString()); } }
执行结果
当sex为0时有如下输出
当sex等于1的时候
这里就完成了整个流程的跑通
其中注意链接的 KIE_CONTAINER_ID和KIE_SESSION_ID的对应关系
