在Jersey网站上的入门指南之后:

我执行了以下构建命令:

$ mvn archetype:generate -DarchetypeArtifactId=jersey-quickstart-grizzly2 \
-DarchetypeGroupId=org.glassfish.jersey.archetypes -DinteractiveMode=false \
-DgroupId=com.example -DartifactId=simple-service -Dpackage=com.example \
-DarchetypeVersion=2.2

然后我按照教程进行操作

@NameBinding

@CORSBinding
static class CrossDomainFilter implements ContainerResponseFilter {
    @Override

        Logger.getLogger("com.example").log( Level.INFO, "before: {0}", cres.getHeaders());
        cres.getHeaders().add("Access-Control-Allow-Origin", "*");
        cres.getHeaders().add("Access-Control-Allow-Headers", "origin, content-type, accept, authorization");
        cres.getHeaders().add("Access-Control-Allow-Credentials", "true");
        cres.getHeaders().add("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS, HEAD");
        cres.getHeaders().add("Access-Control-Max-Age", "1209600");
        Logger.getLogger("com.example").log( Level.INFO, "after: {0}", cres.getHeaders());
    }
}

@Provider
static class MyResponseFilter implements ContainerResponseFilter {

    @Override
    public …
