如何在使用Spring Boot时模拟静态方法？

import static org.mockito.Mockito.*;

@RunWith(MockitoJUnitRunner.class)
public class MyTest {

    @Test
    public void testStaticMethod() {
        mockStatic(StringUtils.class);
        when(StringUtils.isBlank(anyString())).thenReturn(true);

        // 调用被测试的代码，该代码中调用了StringUtils.isBlank()方法
        // 预期结果为true
    }
}

import org.powermock.api.mockito.PowerMockito;
import static org.powermock.api.mockito.PowerMockito.*;

@RunWith(PowerMockRunner.class)
@PrepareForTest(StringUtils.class)
public class MyTest {

    @Test
    public void testStaticMethod() {
        mockStatic(StringUtils.class);
        when(StringUtils.isBlank(anyString())).thenReturn(true);

        // 调用被测试的代码，该代码中调用了StringUtils.isBlank()方法
        // 预期结果为true
    }
}

public interface MyStaticService {
    boolean isBlank(String str);
}

@Service
public class MyStaticServiceImpl implements MyStaticService {
    @Override
    public boolean isBlank(String str) {
        return StringUtils.isBlank(str);
    }
}

@Service
public class MyService {
    private final MyStaticService staticService;

    public MyService(MyStaticService staticService) {
        this.staticService = staticService;
    }

    public void doSomething(String str) {
        boolean result = staticService.isBlank(str);
        // 其他业务逻辑
    }
}

@RunWith(MockitoJUnitRunner.class)
public class MyTest {

    @InjectMocks
    private MyService myService;

    @Mock
    private MyStaticService staticService;

    @Test
    public void testStaticMethod() {
        when(staticService.isBlank(anyString())).thenReturn(true);

        // 调用被测试的代码，该代码中调用了staticService.isBlank()方法
        // 预期结果为true
    }
}
