Java 当ApplicationContext位于另一个上下文中时，Spring@Autowired失败

我正试图整合一个SDK，它通过Spring自己管理的上下文在内部使用Spring。我希望构建的jar是可用的，无论Spring是否在想要使用SDK的应用程序上使用

当它自己运行时，我有一些东西可以工作。但是，如果我尝试在另一个Spring上下文（在我的例子中是基于Spring引导的应用程序）中使用SDK，我会得到一个

org.springframework.beans.factory.NoSuchBeanDefinitionException：没有类型为
的合格bean异常

尽管我尽了最大的努力，但我无法理解如何让它工作，或者我到底做错了什么。下面的类显示了我正在做的事情，org.example.testapp.MySDKTest失败并出现异常，而org.example.test.MySDKTest成功通过。抱歉，代码太多了，但我无法用简化的案例重现这个问题

SDK源代码

package org.example.mysdk;

import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;

import org.example.mysdk.MyService;
import org.example.mysdk.MyServiceConfiguration;

public final class MySDK {

    private static ApplicationContext applicationContext;

    public static <T extends MyService> T getService(Class<? extends MyService> clazz, MyServiceConfiguration configuration) {
        T tmp = (T) getApplicationContext().getBean(clazz);
        tmp.setConfiguration(configuration);
        return tmp;
    }

    private static ApplicationContext getApplicationContext() {
        if (applicationContext == null) {
            applicationContext = new AnnotationConfigApplicationContext(SpringContext.class);
        }
        return applicationContext;
    }
}





测试

第一次测试失败，出现
org.springframework.beans.factory.NoSuchBeanDefinitionException:没有类型为
的合格bean异常

package org.example.testapp;

import static org.junit.Assert.*;

import org.example.mysdk.MyServiceConfiguration;
import org.example.mysdk.MyServiceImpl1;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.support.AnnotationConfigContextLoader;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = App.class, loader = AnnotationConfigContextLoader.class)
public class MySDKTest {

    @Autowired
    MyServiceImpl1 service;

    @Test
    public void test() {

        MyServiceConfiguration conf = service.getConfiguration();

        assertEquals(conf.getValue(), "this is the instance configuration");
    }

}


而且这个试验成功了,

package org.example.test;

import static org.junit.Assert.*;

import org.example.mysdk.MySDK;
import org.example.mysdk.MyServiceConfiguration;
import org.example.mysdk.MyServiceImpl1;
import org.junit.Test;

public class MySDKTest {

    @Test
    public void test() {

        MyServiceConfiguration configuration = new MyServiceConfiguration();
        configuration.setValue("this is the instance configuration");

        MyServiceImpl1 service = MySDK.getService(MyServiceImpl1.class, configuration);

        assertEquals(service.getConfiguration().getValue(), "this is the instance configuration");

    }

}

如果我用了完全错误的方法，我很高兴听到关于如何用不同的方式来做这件事的建议
 您必须修改两个文件

首先
App.java
，它应该扫描
“org.example.mysdk”
包，在抽象类
MyService
中注入
myAutowiredService
，否则必须在
App.java
中创建。而且
MyServiceImpl
1bean的名称必须与
myServiceImpl1
不同，因为它会发生冲突

package org.example.testapp;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.example.mysdk.MySDK;
import org.example.mysdk.MyServiceConfiguration;
import org.example.mysdk.MyServiceImpl1;

@Configuration
@ComponentScan(basePackages = {
    "org.example.testapp", "org.example.mysdk"
})
public class App {

    @Bean
    public MyServiceImpl1 myServiceImpl() {

        MyServiceConfiguration configuration = new MyServiceConfiguration();
        configuration.setValue("this is the instance configuration");

        return MySDK.getService(MyServiceImpl1.class, configuration);
    }
}

其次，在
MySDKTest.java
中，应该插入
myservicecimpl
中创建的
App.java

import static org.junit.Assert.*;

import org.example.mysdk.MyServiceConfiguration;
import org.example.mysdk.MyServiceImpl1;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.support.AnnotationConfigContextLoader;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = App.class, loader = AnnotationConfigContextLoader.class)
public class MySDKTest {

    @Autowired
    MyServiceImpl1 myServiceImpl;

    @Test
    public void createOxiAccountService() {     

        MyServiceConfiguration conf = myServiceImpl.getConfiguration();

        assertEquals(conf.getValue(), "this is the instance configuration");
    }

}

感谢@shazin的回答，我希望有两个完全独立的Spring上下文（基本上我不希望SDK用户知道/关心库在内部使用Spring）。有没有办法在两种情况下保持关注点的分离？
