annotations

问题 I am using JAX-RS for my web services. I have common functionality and would like to use inheritance. I am providing simple CRUD operations. I have defined an interface like so: public interface ICRUD { @POST @Consumes("application/json") @Produces("application/json") @Path("create") public String createREST(String transferObject); @GET @Consumes("application/json") @Produces("application/json") @Path("retrieve/{id}") public String retrieveREST(@PathParam("id") String id); @POST @Consumes(

问题 Regarding iPhone Map Kit cluster pinpoints: I have 1000's of marks that I want to show on the map but it's just too many to handle so I want to cluster them. Are there frameworks available or proof of concepts? That this is possible or is already been done? 回答1: You can use REVClusterMap to cluster 回答2: Note: This is a commercial product I'm affiliated with, but it solves this very problem. I solved this problem in few of my apps and decided to extract it into a reusable framework. It's

问题 Seems like the slow Tomcat 7 startup problem can be resolved with "metadata-complete" set to "true" in the web.xml, like so: <?xml version="1.0" encoding="UTF-8"?> <web-app metadata-complete="true" id="WebApp_ID" version="3.0"... The problem is that Tomcat scans for annotations at startup, and this significantly slows it down. My time is cut down from 25 secs to 5 secs. (More info here: Tomcat and Servlet 3.0 Web Configuration) However, I have some annotations in my code, like: @ManagedBean

问题 I am creating entities that are the same for two different tables. In order do table mappings etc. different for the two entities but only have the rest of the code in one place - an abstract superclass. The best thing would be to be able to annotate generic stuff such as column names (since the will be identical) in the super class but that does not work because JPA annotations are not inherited by child classes. Here is an example: public abstract class MyAbstractEntity { @Column(name=

问题 We'd like to use only annotations with MyBatis; we're really trying to avoid xml. We're trying to use an "IN" clause: @Select("SELECT * FROM blog WHERE id IN (#{ids})") List<Blog> selectBlogs(int[] ids); MyBatis doesn't seem able to pick out the array of ints and put those into the resulting query. It seems to "fail softly" and we get no results back. It looks like we could accomplish this using XML mappings, but we'd really like to avoid that. Is there a correct annotation syntax for this?

问题 I have this spring configuration: @Lazy @Configuration public class MyAppConfig { @Foo @Bean public IFooService service1() { return new SpecialFooServiceImpl(); } } How can I get a list of all beans that are annotated with @Foo ? Note: @Foo is a custom annotation defined by me. It's not one of the "official" Spring annotations. [EDIT] Following the suggestions of Avinash T., I wrote this test case: import static org.junit.Assert.*; import java.lang.annotation.ElementType; import java.lang

问题 I am creating google cloud endpoint api, I am trying to use apiKeyRequired = AnnotationBoolean.TRUE as an example on https://github.com/GoogleCloudPlatform/java-docs-samples/blob/master/appengine/endpoints-frameworks-v2/backend/src/main/java/com/example/echo/Echo.java @ApiMethod(name = "echo_api_key", path = "echo_api_key", apiKeyRequired =AnnotationBoolean.TRUE) public Message echoApiKey(Message message, @Named("n") @Nullable Integer n) { return doEcho(message, n); } My code is this.

问题 I have a situation where I need to enable/disable tests(using AnnotationTransformer listener) based on the parameter coming from my suite files(using ISuiteListener listener). However, when I try to read the parameters in my suite file before calling AnnotationTransformer, I am not able to do so. This does not help: <listeners preserve-order="true"> <listener class name="automation.test.SentinelSuiteListener" /> <listener class-name="automation.test.AnnotationTransformer" /> </listeners> Also
