Spring - 从另一个项目

Question

在我的“服务项目”中，我有：

• SERV-的applicationContext.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">
      <import resource="classpath:repo-applicationContext.xml" />
      <context:annotation-config />
      <bean id="myAppService" class="com.myapp.services.MyServiceImpl"/>
  </beans>
  

• 在pom.xml中，从RepositoryProject导入依赖项

• 的web.xml

  <context-param>
      <param-name>contextConfigLocation</param-name>
          <param-value>/WEB-INF/spring/serv-applicationContext.xml</param-value>
  </context-param>
  
  <listener>
      <listener-class>
         org.springframework.web.context.ContextLoaderListener
      </listener-class>
  </listener>
  <listener>
      <listener-class>
        org.springframework.web.context.request.RequestContextListener
      </listener-class>
  </listener>
  
  <servlet>
      <servlet-name>RestServlet</servlet-name>
      <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
      </servlet-class>
      <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>/WEB-INF/spring/serv-applicationContext.xml</param-value>
      </init-param>
      <load-on-startup>1</load-on-startup>
  </servlet>
  

在我的“ RepositoryProject ”中：

• repo-applicationContext.xml位于：src / main / webapp / META-INF / spring

• RepositoryProject的web.xml：

  <context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>/META-INF/spring/repo-applicationContext.xml</param-value>
  </context-param>
  
  <listener>
      <listener-class>
        org.springframework.web.context.ContextLoaderListener
      </listener-class>
  </listener>
  <listener>
      <listener-class>
         org.springframework.web.context.request.RequestContextListener
      </listener-class>
   </listener>
  

修改： RepositoryProject是一个库：

<packaging>jar</packaging>

当我启动Tomcat时出现此错误：

  

配置问题：无法从URL导入bean定义   location [classpath：repo-applicationContext.xml]

1. 我启动“ServicesProject”
2. repo-applicationContext.xml位于：target / ServicesProject / WEB-INF / lib / repoproject.jar / repo-applicationContext.xml。 RepositoryProject的pom.xml：

<groupId>com.myapp.repository</groupId>
  <artifactId>RepositoryProject</artifactId>
  <packaging>jar</packaging>
  <version>0.0.1-SNAPSHOT</version>
  <name>RepositoryProject</name>
  <url>http://maven.apache.org</url>

  <properties>
      <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
      <springframework.version>5.0.1.RELEASE</springframework.version>
      <java.version>1.8</java.version>
      <maven.compiler.source>1.8</maven.compiler.source>
      <maven.compiler.target>1.8</maven.compiler.target>
  </properties>
    <dependencies> <!--SPRING, MYSQL, HIBERNATE --> </dependencies>
    <build>
...
        <resource>
              <directory>src/main/resources/spring/</directory>
              <filtering>true</filtering>
          </resource>
          <resource>
              <directory>src/main/resources/hibernate/</directory>
              <filtering>true</filtering>
          </resource>
...
</build>

我试过：a）使用classpath *：repo-applicationContext.xml我有：

  

上下文初始化失败   org.springframework.beans.factory.BeanCreationException：错误   创建名为'myAppService'的bean：查找方法解析   失败;嵌套异常是java.lang.IllegalStateException：失败   从ClassLoader中内省Class [com.myapp.services.MyServiceImpl]   [ParallelWebappClassLoader上下文：ServicesProject委托：false。“   MyServiceImpl使用repo-applicationContext中定义的bean。

b）使用classpath：repo-applicationContext.xml

  

java.io.FileNotFoundException

编辑2： 现在我有这个错误：
