运行 Junit 测试时，Spring 6 中不会注入可配置 bean 自动装配字段

Question

我在运行 Junit 测试时遇到问题，该测试使用标记为 @Configurable 的类。可配置标记 bean 自动装配字段不会注入并保持为 Null。

我提供了重现该问题的代码示例项目代码：

SomeDependency.class

package com.codeslab;

import org.springframework.stereotype.Service;

@Service
public class SomeDependency {

    public String doSomethingInSomeDependency() {
        return "doSomethingInSomeDependency";
    }
}

SomeService.class

package com.codeslab;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Configurable;

@Configurable
public class SomeService {

    @Autowired
    private SomeDependency mSomeDependency;

    public String doSomething() {
        return mSomeDependency.doSomethingInSomeDependency();
    }
}

测试代码： SomeTest-Context.xml

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <bean class="com.codeslab.SomeDependency"/>
</beans>

SomeTest.class

package com.codeslab;

import org.junit.jupiter.api.*;
import org.junit.jupiter.api.extension.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit.jupiter.SpringExtension;

@ContextConfiguration(locations = { "/SomeTest-Context.xml" })
@ExtendWith(SpringExtension.class)
public class SomeTest {
    final SomeService mMyService = new SomeService();

    @Autowired
    private SomeDependency mSomeDependency;

    @Test
    public void test() {
        Assertions.assertNotNull(mSomeDependency);

        final String something = mMyService.doSomething();
        Assertions.assertEquals("doSomethingInSomeDependency", something);
    }
}

我尝试用上面的示例代码重现该问题。我已经在上下文中使用了 aop:aspectj-autoproxy/ 。我试图遵循 Spring-aop-可配置测试

但我仍然得到 NPE： java.lang.NullPointerException：无法调用“com.codeslab.SomeDependency.doSomethingInSomeDependency()”，因为“this.mSomeDependency”为空

at com.codeslab.SomeService.doSomething(SomeService.java:23)
at com.codeslab.SomeTest.test(SomeTest.java:32)
at java.base/java.lang.reflect.Method.invoke(Method.java:580)
at java.base/java.util.ArrayList.forEach(ArrayList.java:1596)
at java.base/java.util.ArrayList.forEach(ArrayList.java:1596)

aop:aspectj-autoproxy/ 不应该负责将 Somedependency 注入 SomeService 吗？我在这里遗漏或忽略了什么？

编辑：我更喜欢编译时编织。

请在所有位置将变量重命名为 someDependency 或使用 @qualifier 给出您选择的名称。

 @Autowired
 private SomeDependency mSomeDependency;
