PropertyPlaceholderConfigurer가 ClassPathXmlApplicationContext와 작동하지 않습니다.

Question

PropertyPlaceholderConfigurer를 사용하여 속성 파일에있는 일부 변수를로드하려고하는데 작동하지 않습니다. 인터넷상의 일부 사이트는 spring aop이 classpath에 없을 때 문제가 발생한다고 제안했지만 Aop 프레임 워크가 내 프로젝트에 있음을 확인했습니다. 여기 내 springContext.xml입니다 :

<!-- Register all placeholder locations --> 
<bean 
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" > 
    <property name="order" value="0" /> 
    <property name="ignoreUnresolvablePlaceholders" value="true" /> 
    <property name="locations"> 
     <list> 
      <value>file:/mypath/file.properties</value>    
     </list> 
    </property> 
</bean> 

<!-- Register all placeholder locations --> 
<password-decrypter order="10" id="passwordConfigurer"> 
<decrypter algorithm="PBEWithSHAAnd128BitRC4" key="${Encryption.key}" /> 
    <decryption-entries> 
     <decryption-entry bean-ref="ds" properties="password" /> 
    </decryption-entries> 
</password-decrypter> 

는 그리고 여기에 오류 던지고있다 :

Caused by: org.xml.sax.SAXParseException: cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'password-decrypter'.

이 ClassPathXmlApplicationContext와 PropertyPlaceholderConfigurer와를 사용하는 컨테이너 외부에서 프로그램을 실행할 때 나는 뭔가 다른 일을해야합니까?

Answer 1

대체 방법이 있습니다. 아래에 언급 된대로 시도해 볼 수 있습니다.

applicationContext.xml 대신에 PropertyPlaceholderConfigurer와를 정의,

PropertyPlaceholderConfigurer configurer = new PropertyPlaceholderConfigurer(); 
    ResourceLoader resourceLoader = new DefaultResourceLoader(); 
    Resource resource = resourceLoader.getResource("classpath:localDB.properties"); 

    configurer.setLocation(resource); 
    configurer.postProcessBeanFactory(beanFactory); 

ServletContextListener

그것을 정의 아래의 코드를 사용하는 것은 다음의 BeanFactory ClassPathResource가은을 사용하여 만든 은 XmlBeanFactory이다.

속성 파일 localDB.properties이 충당 값을 포함 할 수 있으며이 $ {Encryption.key}로 applicationContext.xml에서 사용할 수 있습니다, 여기에 Encryption.key는 속성

파일에서 키의 하나입니다
