第 50 章 在 IBM WebSphere Application Server 中配置嵌入式进程引擎和决策引擎

流程

1. 在 pom.xml 文件中声明 Red Hat Business Automation BOM：

   <dependencyManagement>
    <dependencies>
     <dependency>
      <groupId>com.redhat.ba</groupId>
      <artifactId>ba-platform-bom</artifactId>
      <version>7.13.5.redhat-00002</version>
      <type>pom</type>
      <scope>import</scope>
     </dependency>
    </dependencies>
   </dependencyManagement>
   <dependencies>
   <!-- Your dependencies -->
   </dependencies>

2. 在 <dependencies> 标签中声明项目 所需的依赖项。将产品 BOM 导入到项目中后，定义了面向用户的依赖项的版本，因此您无需指定这些 < dependency > 元素的 <version > 子元素。但是，您必须使用 & lt;dependency > 元素来声明您要在项目中使用的依赖项。

   • 对于基本的 Red Hat Process Automation Manager 项目，根据您要使用的功能，声明以下依赖项：

     嵌入式进程引擎依赖项

     <!-- Public KIE API -->
     <dependency>
       <groupId>org.kie</groupId>
       <artifactId>kie-api</artifactId>
     </dependency>
     
     <!-- Core dependencies for process engine -->
     <dependency>
       <groupId>org.jbpm</groupId>
       <artifactId>jbpm-flow</artifactId>
     </dependency>
     
     <dependency>
      <groupId>org.jbpm</groupId>
       <artifactId>jbpm-flow-builder</artifactId>
     </dependency>
     
     <dependency>
       <groupId>org.jbpm</groupId>
       <artifactId>jbpm-bpmn2</artifactId>
     </dependency>
     
     <dependency>
       <groupId>org.jbpm</groupId>
       <artifactId>jbpm-runtime-manager</artifactId>
     </dependency>
     
     <dependency>
       <groupId>org.jbpm</groupId>
       <artifactId>jbpm-persistence-jpa</artifactId>
     </dependency>
     
     <dependency>
       <groupId>org.jbpm</groupId>
       <artifactId>jbpm-query-jpa</artifactId>
     </dependency>
     
     <dependency>
       <groupId>org.jbpm</groupId>
       <artifactId>jbpm-audit</artifactId>
     </dependency>
     
     <dependency>
       <groupId>org.jbpm</groupId>
       <artifactId>jbpm-kie-services</artifactId>
     </dependency>
     
     <!-- Dependency needed for default WorkItemHandler implementations. -->
     <dependency>
       <groupId>org.jbpm</groupId>
       <artifactId>jbpm-workitems-core</artifactId>
     </dependency>
     
     <!-- Logging dependency. You can use any logging framework compatible with slf4j. -->
     <dependency>
       <groupId>ch.qos.logback</groupId>
       <artifactId>logback-classic</artifactId>
       <version>${logback.version}</version>
     </dependency>

   • 对于使用 CDI 的 Red Hat Process Automation Manager 项目，您通常会声明以下依赖项：

     启用 CDI 的进程引擎依赖项

     <dependency>
       <groupId>org.kie</groupId>
       <artifactId>kie-api</artifactId>
     </dependency>
     
     <dependency>
       <groupId>org.jbpm</groupId>
       <artifactId>jbpm-kie-services</artifactId>
     </dependency>
     
     <dependency>
       <groupId>org.jbpm</groupId>
       <artifactId>jbpm-services-cdi</artifactId>
     </dependency>

     嵌入式决策引擎依赖项

     <dependency>
       <groupId>org.drools</groupId>
       <artifactId>drools-compiler</artifactId>
     </dependency>
     
     <!-- Dependency for persistence support. -->
     <dependency>
       <groupId>org.drools</groupId>
       <artifactId>drools-persistence-jpa</artifactId>
     </dependency>
     
     <!-- Dependencies for decision tables, templates, and scorecards.
     For other assets, declare org.drools:business-central-models-* dependencies. -->
     <dependency>
       <groupId>org.drools</groupId>
       <artifactId>drools-decisiontables</artifactId>
     </dependency>
     <dependency>
       <groupId>org.drools</groupId>
       <artifactId>drools-templates</artifactId>
     </dependency>
     <dependency>
       <groupId>org.drools</groupId>
       <artifactId>drools-scorecards</artifactId>
     </dependency>
     
     <!-- Dependency for loading KJARs from a Maven repository using KieScanner. -->
     <dependency>
       <groupId>org.kie</groupId>
       <artifactId>kie-ci</artifactId>
     </dependency>

   • 要使用 KIE 服务器，声明以下依赖项：

     客户端应用程序 KIE 服务器依赖项

     <dependency>
       <groupId>org.kie.server</groupId>
       <artifactId>kie-server-client</artifactId>
     </dependency>

   • 要为 Red Hat Process Automation Manager 创建远程客户端，请声明以下依赖项：

     客户端依赖项

     <dependency>
       <groupId>org.uberfire</groupId>
       <artifactId>uberfire-rest-client</artifactId>
     </dependency>

   • 在创建包含资产的 JAR 文件（如规则和进程定义）时，请将 Maven 项目的打包类型指定为 kjar，并使用 org.kie:kie-maven-plugin 来处理位于 < project > 元素下的 kjar 打包类型。在以下示例中，${kie.version} 是列出的 Maven 库版本，在 Red Hat Process Automation Manager 和 Maven 库版本之间有什么映射？

     <packaging>kjar</packaging>
     <build>
      <plugins>
       <plugin>
        <groupId>org.kie</groupId>
        <artifactId>kie-maven-plugin</artifactId>
        <version>${kie.version}</version>
        <extensions>true</extensions>
       </plugin>
      </plugins>
     </build>

3. 如果您在项目中使用具有持久性支持的进程引擎或决策引擎，您必须通过从 Red Hat Business Automation BOM 文件中复制 version.org.hibernate-4ee7 属性，在 pom.xml 文件的 dependencyManagement 部分中声明以下休眠依赖关系：

   Hibernate 依赖项

   <!-- hibernate dependencies -->
   <dependencyManagement>
     <dependencies>
       <dependency>
       <groupId>org.hibernate</groupId>
       <artifactId>hibernate-entitymanager</artifactId>
       <version>${version.org.hibernate-4ee7}</version>
       </dependency>
   
       <dependency>
       <groupId>org.hibernate</groupId>
       <artifactId>hibernate-core</artifactId>
       <version>${version.org.hibernate-4ee7}</version>
       </dependency>
     </dependencies>
   </dependencyManagement>
