第 7 章 DMN 模型执行

您可以使用 Business Central 在 Red Hat Process Automation Manager 项目中创建或导入 DMN 文件，也可以将 DMN 文件打包为项目知识 JAR (KJAR)文件的一部分，而无需 Business Central。在 Red Hat Process Automation Manager 项目中实现 DMN 文件后，您可以通过部署 KIE Server REST API 的 KIE 服务器执行 DMN 决策服务来执行 DMN 决策服务。

有关使用项目打包和部署方法包括外部 DMN 资产的信息，请参阅 打包和部署红帽流程自动化管理器项目。

7.1. 使用 KIE Server REST API 执行 DMN 服务

直接与 KIE 服务器的 REST 端点交互，提供调用代码和决策逻辑定义之间的最大分离。调用代码完全没有直接依赖项，您可以在完全不同的开发平台（如 Node.js 或 .NET ）中实施。本节中的示例演示了 Nix 风格的 curl 命令，但提供相关信息以适应任何 REST 客户端。

当您使用 KIE Server 的 REST 端点时，最佳实践是定义域对象 POJO Java 类，使用标准 KIE Server marshalling 注解进行注解。例如，以下代码使用域对象 Person 类，该类被正确注解：

POJO Java 类示例

@javax.xml.bind.annotation.XmlAccessorType(javax.xml.bind.annotation.XmlAccessType.FIELD)
public class Person implements java.io.Serializable {

    static final long serialVersionUID = 1L;

    private java.lang.String id;
    private java.lang.String name;
    @javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter(org.kie.internal.jaxb.LocalDateXmlAdapter.class)
    private java.time.LocalDate dojoining;

    public Person() {
    }

    public java.lang.String getId() {
        return this.id;
    }

    public void setId(java.lang.String id) {
        this.id = id;
    }

    public java.lang.String getName() {
        return this.name;
    }

    public void setName(java.lang.String name) {
        this.name = name;
    }

    public java.time.LocalDate getDojoining() {
        return this.dojoining;
    }

    public void setDojoining(java.time.LocalDate dojoining) {
        this.dojoining = dojoining;
    }

    public Person(java.lang.String id, java.lang.String name,
            java.time.LocalDate dojoining) {
        this.id = id;
        this.name = name;
        this.dojoining = dojoining;
    }

有关 KIE 服务器 REST API 的更多信息，请参阅使用 KIE API 与 Red Hat Process Automation Manager 进行交互。

先决条件

  • KIE 服务器已安装并配置，包括具有 kie-server 角色的用户的已知用户名和凭证。有关安装选项，请参阅 规划 Red Hat Process Automation Manager 安装。

  • 您已将 DMN 项目构建为 KJAR 工件并将其部署到 KIE Server： 

    mvn clean install

    如需有关项目打包和部署以及可执行模型的更多信息，请参阅 打包和部署 Red Hat Process Automation Manager 项目。

  • 您有包含 DMN 模型的 KIE 容器的 ID。如果存在多个模型，还必须知道相关模型的 model 命名空间和模型名称。

流程

  1. 确定用于访问 KIE Server REST API 端点的基本 URL。这要求了解以下值（使用默认的本地部署值作为示例）：

    • 主机(本地主机)
    • 端口(8080)
    • 根上下文(kie-server)
    • 基础 REST 路径(services/rest/)

    流量违反项目的本地部署中的基本 URL 示例：

    http://localhost:8080/kie-server/services/rest/server/containers/traffic-violation_1.0.0-SNAPSHOT

  2. 确定用户身份验证要求。

    当用户直接在 KIE 服务器配置中定义时，会使用 HTTP 基本身份验证，并需要用户名和密码。成功请求要求用户具有 kie-server 角色。

    以下示例演示了如何在 curl 请求中添加凭证： 

    curl -u username:password <request>
    Copy to Clipboard Toggle word wrap

    如果使用 Red Hat Single Sign-On 配置 KIE 服务器，请求必须包含 bearer 令牌： 

    curl -H "Authorization: bearer $TOKEN" <request>
    Copy to Clipboard Toggle word wrap

  3. 指定请求和响应的格式。REST API 端点可用于 JSON 和 XML 格式，并使用请求标头设置：

    JSON

    curl -H "accept: application/json" -H "content-type: application/json"
    Copy to Clipboard Toggle word wrap

    XML

    curl -H "accept: application/xml" -H "content-type: application/xml"
    Copy to Clipboard Toggle word wrap

  4. 可选：查询容器以获取已部署决策模型的列表：

    [GET] server/containers/{containerId}/dmn

    curl 请求示例： 

    curl -u wbadmin:wbadmin -H "accept: application/xml" -X GET "http://localhost:8080/kie-server/services/rest/server/containers/traffic-violation_1.0.0-SNAPSHOT/dmn"
    Copy to Clipboard Toggle word wrap

    XML 输出示例： 

    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<response type="SUCCESS" msg="Ok models successfully retrieved from container 'traffic-violation_1.0.0-SNAPSHOT'">

  5. 执行模型：

    [POST] server/containers/{containerId}/dmn

    注意

    属性 model-namespace 会自动生成，每个用户都有所不同。确保所用的 model-namespace 和 model-name 属性与部署的模型匹配。
