Spring custom namespaces with Maven

Question

Hi,

I wrote my own custom namespace for a Spring based project I'm working on. The project is built with maven, and I'd like to put my xsd files in the resources directory. The problem is the spring.schemas directory requires me to define where I put my xsd file. In my dev environment it will be resources/schemas/myschema.xsd. But, when I compile, the contents of the resources get copied to target, not the target directory itself. So in the compiled code, I end up with target/schemas/myschema.xsd. Should my spring.schemas file reference resources/schemas/myschema.xsd? Or just schemas/xsd?

thanks,

Jeff

Answer 1

You can define a linked location in Eclipse. By using a variable to define your workspace root and then creating a linked folder you maintain some measure of portability.

Right-click on the project, select new->Folder

call the folder "schemas", click Advanced>>, select Link to folder in the file system

Select Variables... and pick the WORKSPACE_ROOT variable

Add the relative path to your schemas folder, e.g. [project name]/src/main/resources/schemas

When you finish you'll have a new schemas folder with a little arrow in the corner showing it is linked. You may find you need to force refreshes to get new files to be reflected in the linked location.

When creating a custom namespace for Spring the spring.schemas file should be located in META-INF with an entry like this:

http\://www.springframework.org/schema/context/spring-context-2.5.xsd=org/springframework/context/config/spring-context-2.5.xsd

Your custom schema should be then in src/main/resources/org/springframework/context/config/ to be added in the classpath of the project.

Any good IDE should understand src/main/resources/ as a source code folder and read the schema just well.

NOTE: I pulled this example from the spring-core.jar, just examine it yourself

Hi,

It should only point to schemas/myschema.xsd

target/resources will end up in your classpath so you can safely reference everything there.
