我在用Mockito来模仿 Spring Bean 。
当我模拟一个接口时，它工作得很好。
在我们的应用程序中，有几个@Component bean不实现任何接口。
当我尝试模拟这样的组件时，spring上下文会尝试将属性注入到这些组件中。
Mockito不支持不实现任何接口的mocking spring组件吗？
按要求附上示例

public interface EmployeeInterface {
    public Long saveEmployee(Employee employee);
}

@Component
public class EmployeeImpl implements EmployeeInterface {

    @Autowired
    public EmailSender emailSender

    public Long saveEmployee(Employee employee) {
        ...
    }
}

public interface EmailSender {
    public boolean sendEmail(Email email);
}

@Component
public class EmailSenderImpl implements EmailSender {

    @Autowired
    MailServerInfo  MailServerInfo;

    public boolean sendEmail(Email email) {
        ...
    }
}

public interface MailServerInfo {
    public String getMailServerDetails();
}

@Component
public class MailServerInfoImpl {

    public String getMailServerDetails() {
        ...
    }
}

@Profile("Security-test")
@Configuration
public class SecurityTestMockConfiguration {

    @Bean
    @Primary
    public EmailSender emailSender() {
        return Mockito.mock(EmailSender.class);
    }
}

@ActiveProfiles("Security-test")
@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:context-test.xml" })
public class MyTest {

    @Autowired
    EmployeeInterface employeeInterface;

    @Test
    public void testSaveEmployee() {
        employeeInterface.saveEmployee(employee);
    }
}

字符串
在上面的例子中，如果我使用Mockito模拟EmailSender，它工作得非常好。
在下面的场景中，EmailSender是一个不实现任何接口的Spring组件。在下面的例子中，我在自动布线过程中出错。

public interface EmployeeInterface {
    public Long saveEmployee(Employee employee);
}

@Component
public class EmployeeImpl implements EmployeeInterface {

    @Autowired
    public EmailSender emailSender

    public Long saveEmployee(Employee employee) {
        ...
    }
}

@Component
public class EmailSender {

    @Autowired
    MailServerInfo MailServerInfo;

    public boolean sendEmail(Email email) {
        ...
    }
}

public interface MailServerInfo {
    public String getMailServerDetails();
}

@Component
public class MailServerInfoImpl {

    public String getMailServerDetails() {
        ...
    }
}

@Profile("Security-test")
@Configuration
public class SecurityTestMockConfiguration {

    @Bean
    @Primary
    public EmailSender emailSender() {
        return Mockito.mock(EmailSender.class);
    }
}

@ActiveProfiles("Security-test")
@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:context-test.xml" })
public class MyTest {

    @Autowired
    EmployeeInterface employeeInterface;

    @Test
    public void testSaveEmployee() {
        employeeInterface.saveEmployee(employee);
    }
}

型
在第二个方案中，自动装配失败，因为EmailSender找不到MailServerInfo实现。
