Spring: не может загрузить свойства на JUnit с PropertyPlaceholderConfigurer

Wire test setup Spring: не может загрузить свойства на JUnit с PropertyPlaceholderConfigurer

Примечания: Я добавил проекты, описанные выше, в файловой службе падения для удобного воспроизведения и просмотра ->http://dropcanvas.com/ujzw5

доступно только для 3 дней.

Проблема: У меня есть программа, которая работает, называется SomeBean. Запустив его, я получаю ожидаемые результаты и весеннюю проводку.

Я хотел бы сделать отдельный тестовый проект, который имеет тестовый класс с JUnit: ACME-упаковке2, чтобы проверить мою проводку на акме-упаковке1. Это отлично работает, если SomeBean вводится другими компонентами, но не свойствами PropertyPlaceholderConfigurer.

Мой вопрос: Я хотел бы знать, как сделать SomeBeanWireTest от acme-package2 работы.

Я не хочу, чтобы изменить SomeBean класс ACME-упаковке1, и я хочу продолжать использовать springcontext.xml с пути CLASSPATH место на PropertyPlaceholderConfigurer, если это возможно.
Поскольку мой тест заключается в проверке проводки acme-package1, я не хочу иметь другой springcontext.xml в тестовом проекте, потому что он поражает цель тестирования проводки исходного проекта.
Моя надежда заключается в том, что на SomeBeanWireTest я могу что-то сделать, чтобы протестировать проводку SomeBean без изменения кода SomeBean. Вот код проекта:

SomeBean:

package com.acme.package1; 

import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.context.ConfigurableApplicationContext; 
import org.springframework.context.support.ClassPathXmlApplicationContext; 

public class SomeBean { 
    private final static String CLASSPATH_METAINF_PREFIX = "classpath*:META-INF/"; 
    @Autowired 
    private String injectedString; 

    public void setInjectedString(String injectedString) { 
    this.injectedString = injectedString; 
    } 

    public static void main(String[] args) 
    { 
    ConfigurableApplicationContext springContext = new  ClassPathXmlApplicationContext(CLASSPATH_METAINF_PREFIX + "springcontext.xml"); 
    SomeBean testBean = springContext.getBean(SomeBean.class); 
    testBean.printInjectedString(); 
    springContext.close(); 
} 

private void printInjectedString() { 
    System.out.println("Injected String: " + injectedString); 
} 
}

acme.properties: springcontext.xml

acme.injectedString=I am an injected String

Что случилось с проверкой каталогов из вашего пакета 1? – Palcente

В пакете 1 нет тестовых каталогов. Eclipse скрывает его, когда вы не добавляете никаких тестов. Эти 2 проекта были сделаны специально, чтобы показать проблемы, поэтому на упаковке 1 нет теста1. –

Поскольку springcontext.xml явно устанавливая injectedString свойство, нет никаких причин, чтобы аннотировать поле с @Autowired.Я не уверен, почему он работает в одном контексте, но не в другом. Может быть разница в поведении ClassPathXmlApplicationContext (используется в основном методе) и GenericApplicationContext (используется тестовым классом).

В любом случае, устранение @Autowired устранит проблему. Другим вариантом будет аннотация injectedString с @Value("${acme.injectedString}") и удаление линии <property name="injectedString" value="${acme.injectedString}" /> из springcontext.xml.
