我在jboss\u home\standalone\deployments中部署了两个spring应用程序jar。当我试图在app2中访问app1的springbean服务时，我得到了nullpointerexception

@Service
public class App1ServiceImpl {
    public void checkApp1Service() {
        System.out.println("Service Called");
    }
}

@Service
public class App2ServiceImpl {
    @Autowired
    private App1ServiceImpl app1ServiceImpl;
    public void checkService() {
        app1ServiceImpl.checkApp1Service();
    }
}

收到的错误如下：

代码结构如下：
我在每个maven项目的src\main\resources\web inf文件夹下都有jboss-spring.xml，如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:jee="http://www.springframework.org/schema/jee"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:task="http://www.springframework.org/schema/task"
    xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.1.xsd">
    <context:component-scan base-package="com.myapp1.service" />
</beans>

和

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

    <context:component-scan base-package="com.myapp2.service" />
</beans>

另外，我在src\main\resources\webinf下有jboss-deployment-structure.xml，如下所示
对于myapp1

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <dependencies>
            <module name="com.spring"/>
        </dependencies>
    </deployment>
</jboss-deployment-structure>

对于myapp2

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <dependencies>
            <module name="com.spring"/>
            <module
                name="deployment.myapp1-0.0.1-SNAPSHOT.jar" annotations="true" services="import" meta-inf="import"/>
        </dependencies>
    </deployment>
</jboss-deployment-structure>
