Proposals on POJO/Java Bean serializing

[fuweichin]

When serializing POJO/Java Bean, I have some ideas to mention:

1. Follow common convention with common JSON library like Gson,Jackson,Fastjson

• static fields should not be serialized
• fields without public getter should not serialized

such that actual response body will be as same as possible with expected body describe by JSONDoc

2. Customize domain-specific business:

• only fields with public setters should be serialized for request body
• fields without public getters should not be serialized for response body

such that actual request body would not pass read-only fields to server, actual response body would not pass write-only fields to client.
and JSONDoc will be more tight-integrated with back-end services in real application scenarios.
