I'm using Jersey in Java for a simple web server. I'm trying to handle with url query parameters, like
/path?value1=X&value2=Y&value3=Z
I was able to extract the query value by using the @QueryParam annotation like
@GET
@Produces(MediaType.APPLICATION_XML)
@Path("/path")
public String getUpdate(@QueryParam("All") List<String> allParam,
@QueryParam(value = "value1") String value1,
@QueryParam(value = "value2") String value2,
@QueryParam(value = "value3") String value3) {
...
}
Now my problem is I need to validate the input. I'm mainly trying to make sure that value1, value2 and value3 follow a specific format. I also want to make sure that those parameters are not empty.
I checked out the Bean Validation documentation for Jersey, but it seemed hard to follow. This is probably because I'm still somewhat new to Jersey framework.
So how can I set up query parameter validations? Are there easier to follow resources/examples I could be directed to? Thanks
