春季启动-使用2个库的junit：IllegalArgumentException：无法解析占位符

Question

如果删除一行代码，我可以使用spring boot @Value。不幸的是，我需要保留这行代码-因为它确实是我尝试在junit测试中使用的其他库的一部分。如果我不需要这个其他库，那就没问题了。

导致此问题的行是这一行。 ApplicationContext applicationContext = new ClassPathXmlApplicationContext（“ mycontext.xml”）;

执行此行似乎会更改已经完全加载的上下文，这样就可以找到@Value项。

如何修复我的junit，以使获取该另一个库的Bean实例不会与现有库冲突？

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.NONE)
@ContextConfiguration(locations = "/myContext.xml") 
@TestPropertySource(locations = {"classpath:test.properties"})
public class MyTest {

    @Autowired
    MyService myService;


    public void myTest() {

        // This is really a call to another library (it's the call that fails from a getInstance from its initialize
        // Within that initialize call, there's a line that tries to load a new XML applicationContext.
        // If I comment this line, I don't have the problem described, but I need to use this class of course.
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("mycontext.xml");

        //If above line is commented, I have the value in the mapped variable which uses @Value("${myProperty}")
        // but if the line is not commented, I get the IllegalArgumentException: 
        // Could not resolve placeholder 'myProperty' in value "${myProperty}"
