feat(java): add shared GET /info REST controller to nv-boot-starter-core - #1212
feat(java): add shared GET /info REST controller to nv-boot-starter-core#1212shelleyshen-0 wants to merge 9 commits into
Conversation
Add an auto-configured InfoController serving a flat {service, version, commit}
body on GET /info, mirroring the existing shared HealthController. Reads
git.properties directly for the commit SHA and build version, so it works
consistently across consuming services without depending on Actuator's info
exposure or property-source ordering.
📝 WalkthroughWalkthroughAdds full Git commit metadata propagation and a web-conditional ChangesService info endpoint
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The new /info endpoint may return blank service or version fields when those settings are explicitly configured as empty instead of using the documented fallback values. This is a bounded correctness issue that should receive owner awareness or a small follow-up before or after merge. Sequence Diagram(s)sequenceDiagram

Properties.getProperty(key, default) only falls back when the key is absent, not when it's present but blank. Use StringUtils.defaultIfBlank so /info still reports "unknown" for a blank git.commit.id.full instead of an empty string.
log.warn omitted the IOException as the final SLF4J argument, so the stack trace/cause was never recorded when git.properties failed to load.

You shouldn't need this. BootCoreEnvironmentProcessor already adds nv-boot-git-properties as Spring PropertySource. You should be able to use Spring APIsto get that property source like this:
@Autowired
private Environment environment;
...
var propertySource = environment.getPropertySources().get("nv-boot-git-properties");
var version = propertySource.getProperty("git.what.ever"); // Look in BootCoreEnvironmentProcessor

Comments become stale very quickly. Your code should be self-documenting. This comment does not add any value. Let's remove it. This is a generic comment. Keep only those comments that are useful -- where you are doing something which isn't usual/normal -- so that the at a later time you or anybody else would know why we did what we did.

Add app.git.commit.full to the nv-boot-git-properties source in BootCoreEnvironmentPostProcessor, then have InfoResponseService read spring.application.version and app.git.commit.full from Environment directly instead of re-parsing git.properties in a separate GitBuildInfo class.

Spring Framework Environment getProperty(String key, String defaultValue) Javadoc empty string default value
💡 Result:
The Spring Framework's PropertyResolver interface (which the Environment interface extends) provides the getProperty(String key, String defaultValue) method [1][2][3]. According to the official Spring Framework Javadoc, this method is defined to return the property value associated with the given key if it can be resolved; otherwise, it returns the provided defaultValue [1][4][3]. There is no special logic or exception made for an empty string; if you pass an empty string ("") as the defaultValue, it will be returned exactly as provided when the property key cannot be resolved [1][5][3]. The method does not treat an empty string defaultValue as null or otherwise invalid [1][6]. It functions as a straightforward fallback mechanism where the defaultValue argument is returned if and only if the specified property key is not found in the environment's configured property sources [1][7][6].

Normalize blank environment values before applying the fallback.
org.springframework.core.env.Environment#getProperty(String, String) applies "unknown" only when the property is unresolved. An empty configured value passes through to InfoResponse. Add blank-value handling for both properties and cover it in InfoResponseServiceTest.
