從父模塊向子模塊添加配置文件的Spring模塊war

Question

我有一個從父模塊讀子模塊的配置問題。這個子模塊被用作戰爭項目來部署服務器。情況是這樣的

的applicationContext

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> 

    <import resource="applicationContextOutside.xml"/> 

    <bean id="secondsToRedirect" class="java.lang.Integer"> 
     <constructor-arg ref="beanOutside"></constructor-arg> 
    </bean> 

</beans> 

applicationContextOutside.xml

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> 

    <bean id="beanOutside" class="java.lang.Integer"> 
    <constructor-arg value="5"></constructor-arg> 
    </bean> 

</beans> 

的web.xml

<?xml version="1.0" encoding="ISO-8859-1"?> 
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://www.oracle.com/webfolder/technetwork/jsc/xml/ns/javaee/web-app_3_0.xsd" version="3.0"> 
    <display-name>zetoRA</display-name> 
    <context-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value>classpath:/applicationContext.xml</param-value> 
    </context-param> 
    <listener> 
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
    </listener> 
    <servlet> 
    <servlet-name>dispatcher</servlet-name> 
     <servlet-class> 
      org.springframework.web.servlet.DispatcherServlet 
     </servlet-class> 
     <load-on-startup>1</load-on-startup> 
    </servlet> 

    <servlet-mapping> 
    <servlet-name>dispatcher</servlet-name> 
     <url-pattern>/</url-pattern> 
    </servlet-mapping> 
</web-app> 

的pom.xml（parenModule）

我需要將applicationContextOutside.xml導入WarModule，或者更好地從配置/ applicationContextOutside.xml配置我的Spring bean，並省略applicationContext.xml。問題是子模塊中文件applicationContextOutside.xml的可見性。簡而言之，我需要從外部加載Spring配置。如果有人做了這樣的事情？

Answer 1

1. 創建一個簡單的Maven項目（這將是父級，父級模塊），並在pom.xml中定義war-module和jar-module的通用依賴關係。

2. 創建一個新的maven模塊war-module，並將其定義爲父模塊的war和child。您將在這裏擁有web.xml和一個applicationContext.xml。

3. 創建一個新的maven模塊jar-module，並將其定義爲父模塊的jar和子模塊。你將在這裏有另一個applicationContext.xml。

4. 在來自war-module import jar-module的pom.xml文件中作爲依賴項。

5. 從戰爭模塊導入的applicationContext.xml applicationContext.xml中從罐子模塊像here
