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]

我启动“ServicesProject”
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：
