将JAX-RS结果集转换为数组无循环

// 结果集类
@XmlRootElement
public class Result {
    private String[] data;

    public String[] getData() {
        return data;
    }

    public void setData(String[] data) {
        this.data = data;
    }
}

// 实体提供者类
@Provider
@Produces(MediaType.APPLICATION_JSON)
public class ResultArrayProvider implements MessageBodyReader<Result[]> {

    @Override
    public boolean isReadable(Class<?> type, Type genericType, Annotation[] annotations, MediaType mediaType) {
        return type == Result[].class;
    }

    @Override
    public Result[] readFrom(Class<Result[]> type, Type genericType, Annotation[] annotations, MediaType mediaType,
                             MultivaluedMap<String, String> httpHeaders, InputStream entityStream) throws IOException, WebApplicationException {
        // 从entityStream中读取HTTP请求的实体，并将其转换为Result[]数组
        // ...
    }
}

// JAX-RS资源类
@Path("/example")
public class ExampleResource {

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public Result[] getResults() {
        // 获取结果集并转换为Result[]数组
        // ...
        return results;
    }
}
