Swagger Codegen use existing class

Question

How can I get the swagger codegen to use an existing class instead of creating a new class? Is this possible? For instance I want to use org.springframework.data.domain.Pa

Answer 1

You could use --import-mappings, as it is explained here:

Sometimes you don't want a model generated. In this case, you can simply specify an import mapping to tell the codegen what not to create. When doing this, every location that references a specific model will refer back to your classes.

You call this on swagger-codegen-cli generate, with the example you included it would be

--import-mappings Page=org.springframework.data.domain.Page

Although importMappings hasn't been included in the general configuration parameters here if you look at the code here you can see it's a List. I haven't used it with the maven plugin but looking at the doc and the code I'm guessing this should work:

    io.swagger
    swagger-codegen-maven-plugin
    2.2.2-SNAPSHOT
    
        
            ...
            
                ...
                
                   Page=org.springframework.data.domain.Page
                
            
        
    
 

But this was recently changed, so it might be different if you're using an older version of the plugin. Before that changed it seems to be like this:

    io.swagger
    swagger-codegen-maven-plugin
    2.2.2-SNAPSHOT
    
        
            ...
            
                ...
                
                   Page=org.springframework.data.domain.Page;Some=org.example.Some
                
            
        
    

According to the comment in that commit the old version should be supported too, but I haven't tried any of this so let me know if it works.
