Question

我遇到了从父模块到子模块的Spring配置问题。此子模块用作war项目以部署服务器。情况就是这样

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>

pom.xml（parenModule）

我需要将applicationContextOutside.xml导入WarModule，或者更需要从配置/ applicationContextOutside.xml配置我的Spring bean并省略applicationContext.xml。问题是子模块中文件applicationContextOutside.xml的可见性。简而言之，我需要从外部加载Spring配置。如果有人这样做过吗？

创建一个简单的Maven项目（这将是父模块，父模块），并在pom.xml中定义war-module和jar-module的公共依赖项。
创建一个新的maven模块war-module，并将其定义为父模块的war和child。您将在这里获得web.xml和一个applicationContext.xml。
创建一个新的maven模块jar模块，并将其定义为父模块的jar和子节点。你将在这里有另一个applicationContext.xml。
在war-module import jar-module的pom.xml文件中作为依赖项。
来自war-module的applicationContext.xml从jar模块导入applicationContext.xml，如here

将Spring的配置文件从父模块添加到子模块war
