问题
I'm learning Spring using the Getting Started Guides. Right now I'm trying to complete "Accessing JPA Data with REST" guide but my code didn't work, so I tried the "complete" version, and it doesn't work too. So far everytime I import content using Spring Tool Suite (STS), the "complete" version executes as expected, according to the description in the guides, but it's not happening right now.
The guide instructs me to run the Project as a "Spring Boot App", then to execute a curl command to see the top level service:
Command:
$ curl http://localhost:8080
Expected output:
{
"_links" : {
"people" : {
"href" : "http://localhost:8080/people{?page,size,sort}",
"templated" : true
}
}
}
My output:
{"timestamp":1472183640477,"status":404,"error":"Not Found","message":"No message available","path":"/"}
I'm on machine with Windows 10 Pro x64, Java 1.8.0_102, STS version 3.8.1.RELEASE, build id 201607290850 and using Spring Boot version 1.4.0.RELEASE. I am using Maven to build inside STS.
The code is very simple, only three classes, and I haven't changed anything. You can check the code here on github. The Spring Guide is here.
Here's my console output, I think I may be missing some important message and it would help to identify the problem:

There are only a few URL mappings, and none points to /people, so no wonder you get a 404 error.
I just git-cloned the project, build it and run it with NetBeans under Windows. here is the console output (I skipped a few lines due to StackOverflow 30k characters limit):

You can see there are many mappings (all the Mapped "{[/{repository}/ lines) than what you got.
I get the same result if I build and run the project manually using:
mvn clean package
java -jar target\target\gs-accessing-data-rest-0.1.0.jar
Does STS show the commands it uses?
回答2:
I executed the build from Maven and this time it showed a message that a jar file was corrupted:
[WARNING] error reading C:\Users\Alisson\.m2\repository\org\springframework\data\spring-data-rest-webmvc\2.5.2.RELEASE\spring-data-rest-webmvc-2.5.2.RELEASE.jar; invalid LOC header (bad signature)
I deleted the "spring-data-rest-webmvc" folder and, next time I ran the build, Maven downloaded the correct jar again. Now it works from command line and inside STS too.
STS wasn't showing this error message and I had tried "Update Project... / Force Update of Snapshots/Releases", so I guess the best option is to always use Maven to build instead of "Run as Spring Boot App".
