inject

问题 This is probably really stupid but I've spent the last 2 hours trying to figure out how to do this with no luck at all. Basically I need my html page to do the following: <div class="circleElement"> ... </div> But I need to add more classes to that div class with ruby, the classes are coming in from a text field in my database. I tried inserting ruby like: <div class="circleElement"+ <%= u.tag %> >...</div> And many different variations of this line with no luck at all :( I should add that u

问题 I'm trying to inject a class called MeasurementService into an AspectJ Annotation class called MeasurementAspect but I received an error of NullPointerException and I checked that the injection of MeasurementService is null in this case. The injected class itself is then triggered in one of the advices . The MeasurementAspect class itself doesn't have constructor as I think there is no need to have it and all advice will be injected to the appropriate methods and executed automatically. Here

问题 I want to inject bean inside my method. I have remote method(Direct Web Remoting) and i need to inject some bean inside this method. I can't use @Inject annotation in field declaration section because it will not work. It is even possible ? 回答1: It could be possible using serious bytecode instrumentation, but that's probably not feasible. Does DWR prevent you from using regular Injection? 回答2: There are lots of ways to do something like this. What container do you run? DWR doesn't seem to

问题 This may looks like a duplicate of this question. But this is different. I was trying to refactor my legacy code by using method injection in spring. I have a bean class which contains many static helper methods. My targeted method as follows: Context.java private static MessageSender messageSender; //... public static MessageSender getMessageSender(){ return messageSender; } Context bean <bean id="context" class="org.abc.Context"> <property name="messageSender"><ref bean="mailMessageSender"/

问题 Hello and thank you in advance for reading this. Im trying to make chrome extension navigate to a website and interact with a form on that website. The way we are doing this right now is we are making the user input into the extension the origin and the destination, then we are trying to open in a new tab the website, inject the input that the user entered in the extension into the form and clicking the submit button. Is there anyway to do this with a chrome extension? again Thank you! 来源：

问题 Based on the proposed solution here, I am trying to use CDI @Produces to be able to access with @Inject multiple properties files: Bundle Interface package com.locale; import java.lang.annotation.ElementType; import java.lang.annotation.Retention; import java.lang.annotation.RetentionPolicy; import java.lang.annotation.Target; import javax.enterprise.util.Nonbinding; import javax.inject.Qualifier; @Qualifier @Target({ElementType.TYPE, ElementType.METHOD, ElementType.FIELD, ElementType

问题 I have two lists that consist of strings, both immmutable: def list1 = [ "A", "B", "C" ] list2 = ["D", "E", F"] List 2 is being returned by a custom function I have made. Is there a way to take these two immutable lists and combine both of their elements with inject? I have tried numerous combinations without success. I have googled extensively for this. I cannot change this to a mutable list. I am aware that it would be much easier to simply combine two lists then make them immutable, but

问题 This is relevant to one asked in Pass Parameter to Instance of @Inject Bean but i need some different approach for my implemenation. For passing parameter while injecting, a custom qualifier can be created like : @Qualifier @Target({ TYPE, METHOD, PARAMETER, FIELD }) @Retention(RUNTIME) @Documented public @interface SendInject{ @Nonbinding int value() default 0; // int value will be store here } The class to be injected need to be annotated with @SendInject as: @SendInject public class

问题 We want to optimize our application. There is some streight linear work going on, that can be executed in multiple threads with smaller working sets. Our typical service is accessed using the @Inject annotation from within our CDI-managed beans. Also such a service could have it's own dependencies injected, i.e.: public class MyService { @Inject private OtherService otherService; @Inject private DataService1 dataService1; ... public void doSomething() { ... } } Because I can not use @Inject

问题 What's the best way - or, indeed, any way - to calculate a running total in Rails? I have a model, Sale. It has a quantity column and a sales_value column. I need to populate a third column, total_quantity, with the sum of the quantity values of the previous records, when the table is sorted by isbn_id, then channel_id, then invoice_date. This sets all sorts of sensible database management alarm bells ringing, so I'm wondering if it's even possible. The reason for needing this cumulative sum
