描述

Description

Defining an api operation with composite parameter causes a ComposedModel to be generated. The swagger-codegen then does not handle that type in class DefaultCodegen function fromParameter. Resulting in a null pointer exception.

Swagger-codegen version

2.2.2-SNAPSHOT

Swagger declaration file content or url

Use Animal object from the swagger spec as body object in the operation.

Command line used for generation

java -jar swagger-codegen/modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate -l jaxrs-cxf - -i api.json

研究方向
The issue requires implementing support for ComposedModel in the fromParameter method of DefaultCodegen class. The fix should handle composite body parameters correctly to avoid NullPointerException. Suggested approach: check if the parameter's schema is a ComposedModel and handle accordingly. See relevant source files in modules/swagger codegen/src/main/java/io/swagger/codegen/DefaultCodegen.java.
