问题 I'm new in Spring and this is my first post here, I'm starting to use spring annotations, I was able to cofigure my project using XML configuration and now I'm able to configure it using only annotations and avoiding XML. But my current need is to avoid the use of annotations in my java classes (beans) and use it only in my AppConfig.java class which I use to configure Spring. This is my current working configuration: AppConfig.java @Configuration @ComponentScan(basePackageClasses=

问题 I have constants, that are made of other, smaller constants. For example object MyConstants { final val TABLENAME = "table_name"; final val FIELDNAME = "field_name"; final val INDEXNAME = TABLENAME + "_" + FIELDNAME + "_ix"; // this one does not want to be constant } I want these to be true constants because I use them in annotations. How do I make it work? (on scala 2.11) What I want is interface MyConstants { String TABLENAME = "table_name"; String FIELDNAME = "field_name"; String INDEXNAME

问题 I have an annotation public @interface Field { String value(); } and java class, annotated by it: public class Animal { @Field("name") private String name; } I try to list all field' annotations by the next code: for(field in clazz.declaredFields){ for(annotation in field.annotations){ when(annotation){ is Field -> { //do something } } } } where clazz is Class<T> but field.annotations is empty.

问题 Let's say we have this method with annotation: @Cached(key="search" + id) public static List<String> search(String id) { //... } I want to pass parameter "id" to the @Cached annotation's key.

问题 I have some value from my configuration file, that should be a JSON (which will be loaded as a String). I'd like Spring to validate that this value is indeed a valid JSON before injecting it and throw an error else. I've read about the validation annotations that exist, such as - @NotNull, @Size, @Min, @Max, @Email, @NotEmpty etc. Is there any way to create a custom validator? I want a validator that will attempt to convert the String to JSON, as in the following example: How to convert

问题 I'm trying to dynamically add annotations to my high charts in React. I'm using the addAnnotation function to add a new annotation whenever a hover event is triggered on my app, but the annotation does not render. I dropped a debugger into my code, and when I call chart.annotations I can see there is currently an array of annotations, but they are not rendering. I even have make a call to the addPlotLine in this function and the plotline is rendered on the chart. My config file looks like
