A Spring self-check tests spring mvc and security boundary using the source-kit contracts.
Review before answering
- Spring MVC request validation: reject invalid commands before mutation
- Spring MVC ProblemDetail: stable errors without leaking internals
- Spring API pagination: bounded requests and immutable snapshots
- Spring MVC CORS: a browser-origin policy is not authentication
- Spring Security filter chain: authentication, CSRF and request order
- Spring PasswordEncoder: salted verification rather than reversible storage
- Spring MockMvc tests: HTTP behavior without claiming a real network test
- Spring Security JWT tenant principal: map only a validated claim
- Spring Security scope versus tenant ownership: two separate decisions
- Spring JWT tenant claims: reject missing or malformed ownership before conversion
- Spring JdbcTemplate tenant predicates: put ownership in the SQL query
- Test Spring JWT authorization through filters, service proxy and SQL
- Spring MVC multipart receipt import: validate before storing
- Spring multipart size limits: enforce parser and application budgets
- Spring file uploads: discard the supplied filename before writing
- Spring MockMvc multipart tests: what the fixture proves
- Spring Boot readiness health group: withdraw traffic on a required dependency failure
- Spring Security health probes: expose only the health path

Answer every question, then read the explanations. This browser self-check is not a credential or a server-side code judge.
Common Mistakes
Distinguish a checked local fixture from a production guarantee. Container ownership, database atomicity and request authorization require separate evidence.
