CDI 和 Java EE 集成
The camunda-engine-cdi module provides programming model integration with CDI (Context and Dependency Injection). CDI is the Java EE 6 standard for Dependency Injection. The camunda-engine-cdi integration leverages both the configuration of the Camunda engine and the extensibility of CDI. The most prominent features are:
- A custom El-Resolver for resolving CDI beans (including EJBs) from the process,
- Support for @BusinessProcessScoped beans (CDI beans, the lifecycle of which are bound to a process instance),
- Declarative control over a process instance using annotations,
- The Process Engine is hooked-up to the CDI event bus,
- Works with both Java EE and Java SE,
- Support for unit testing.
Quarkus Engine Extension
Since Quarkus ArC does not aim to fully implement CDI 2.0, you cannot use the full range of features the camunda-engine-cdi module provides.
Read about the limitations in the Quarkus Integration guide.
Maven Dependency
To use the camunda-engine-cdi module inside your application, you must include the following Maven dependency:
Please import the Camunda BOM to ensure correct versions for every Camunda project.
<dependency>
<groupId>org.camunda.bpm</groupId>
<artifactId>camunda-engine-cdi</artifactId>
</dependency>
Replace ‘x’ with your Camunda Platform version.
There is a project template for Maven called camunda-archetype-ejb-war, which gives you a complete running project, including CDI integration.
