本地运行Tibco项目时，运行时引用模块属性还是应用属性？

Great question—this is a super common gotcha when you're working locally with Tibco BW6, so let's break it down clearly based on how you're running your project:

1. Running a single module directly in Tibco Studio #

If you right-click a module and select "Run As > Tibco BusinessWorks 6 Application" (without wrapping it into an application first), the runtime will only reference the module's own Module Properties (the module.properties file under your module's src/main/resources folder). Application-level properties don't come into play here at all—your module runs in isolation, using its own configured values.

2. Running an Application that includes your module #

If you've packaged your module into a Tibco Application (via the Application Project type) and run the entire application locally, the runtime follows a clear priority hierarchy:

• Application-level properties (from the application's application.properties file) take precedence over module-level properties for any keys that are shared between the two.
• For properties that only exist in the module's Module Properties and aren't defined in the application, the module's values will still be used.

Example to clarify #

Suppose your module's module.properties has:

db.connection.url=jdbc:mysql://localhost:3306/module-db
api.timeout=3000

And your application's application.properties has:

db.connection.url=jdbc:mysql://localhost:3306/app-db

When you run the entire application locally, the runtime will use:

• db.connection.url=jdbc:mysql://localhost:3306/app-db (application-level value overrides module)
• api.timeout=3000 (module-level value, since no application override exists)

Quick note on run configurations #

If you want to customize this behavior (e.g., load a custom properties file instead of the default), you can tweak the Run Configuration in Tibco Studio. But the above is the out-of-the-box behavior for most local development workflows.
