annotations

问题 With the following code I am plotting a candlestick graph and also make use of annotations. I have played arround until I found the right positions for the text, but I still don't understand what the figures xytext=(-15, -27) and xytext=(-17, 20) have to do with their current position. It is very strange to me. could somebody please explain it to me? Many thanks in advance! This is what my graph looks like and below is the code: import matplotlib.pyplot as plt import matplotlib.dates as

问题 I am writing a wrapper for a C library in Python. I am trying to properly annotate all of the methods, so my IDE can help me catch errors.

问题 Admittedly, I didn't look too hard for an answer. My question is, when defining swagger annotations using springfox-swagger-ui , how does one define common ApiResponse used for more then one method and potentially more then one class? See the 2 sample methods below the common ApiResponse is error 500. Ideally, I would want to define that once. Any best practices and/or suggestions? Sample code below: @GET @Path("/greeting") @Produces(MediaType.APPLICATION_JSON) @ApiOperation(value = "Returns

问题 I am working on annotating images using xml. I am using xmlstarlet and unix bash commands but I am facing some issues when I try to append a value to an existing xml attribute value. For example, I have <filename>a</filename> and I want to make it <filename>a.jpg</filename> (i.e. concatenate '.jpg' to the existing value). I used the following piece of code but it totally overwrites the value (i.e. <filename>.jpg</filename> . Script: for name in *.xml; do xmlstarlet ed --inplace -u '

问题 I would like add an annotation similar to @RequestParam, though have it pull the values from the request attribute rather than the request param... Is there an example or explanation how to create my own annotation for this and the handler / binder needed as well? Thanks 回答1: The blog entry with the title "Extending Spring MVC's annotation controller" answers your question. Google it to find it since Stackoverflow won't let me create the direct link. Basically you create an @RequestAttribute

问题 I have a web application on Tomcat 7.0.34, Spring 3.2.3, Spring Security 3.2.0.RC1 and Spring Social 1.1. For some reason the Spring context is being loaded twice. The second load is happening immediately after the first load has finished. The log below shows the Context Loader loading the Root WebApplicationContext. Everything progresses normally and all the RequstMappingHandlers are registering correctly. Then immediately the context is refreshed again. I've read several solutions on SO

问题 as far as i know, the only way to make the annotation take effect is reflection. Without reflection, java annotation become useless. Is this right? public class Main{ @SomeAnnotation(name="some",value="annotation") public void method(){ //do something. } public static void main(String...args){ Main main = new Main(); //Just call the method directly, How to make the @SomeAnnotation make sense? main.method(); } } For instance, you first get a java Method object, then check all the annotations
