any() @value字段的匹配器 Strict stubbing argument mismatch 错误。
有吗 ArgumentMatcher 是否适合 @Values 字段？也许有人知道为什么“any（）”不起作用？
字段( sampleVersion )，我使用@value注解从application.properties获得，它在测试值中有 null （证明-第一行日志）。甚至日志也显示 null 应该是matcher null .
ps我用这个解决了这个问题：

ReflectionTestUtils.setField(someClass, "serviceUrl", "value");

但我很好奇这有必要吗？为什么这么简单 any() 不起作用。
日志：

sampleVersion has value: null

Strict stubbing argument mismatch. Please check:
 - this invocation of 'postForEntity' method:
    restTemplate.postForEntity(
    null,
    <{key=null},[Content-Type:"application/json"]>,
    class java.lang.String
);
    -> at com.some.package.SomeClass.someMethod(SomeClass.java:126)
 - has following stubbing(s) with different arguments:
    1. restTemplate.postForEntity(null, null, null);
      -> at com.some.package.SomeClassTest.someTest(SomeClassTest.java:59)

方法：

@Value("${sample.version}")
    private String sampleVersion;

    public ResponseEntity someMethod()  {

    System.out.println("sampleVersion has value: " + sampleVersion);

    Map<String, Object> paramMap = new HashMap<>();
    paramMap.put("key", sampleVersion);

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);

    return restTemplate.postForEntity(sampleVersion, new HttpEntity<>(paramMap, headers), String.class);
    }

测试：

@InjectMocks
    SomeClass someClass = new SomeClass();

    @Test
    void someTest() {
    //given
    ResponseEntity response = new ResponseEntity("{ \"text\" : \"hello\"}", HttpStatus.OK);

    //when
    when(restTemplate.postForEntity(any(), any(), eq(String.class))).thenReturn(response);
    ResponseEntity responseEntity = someClass.someMethod();

    assertNotNull(responseEntity);
    }
