Spring 3.2:@scope（“request”）的单元测试不再有效

Question

@Component
public class MockRequestBeanFactoryPostProcessor implements BeanFactoryPostProcessor {

public void postProcessBeanFactory(
        ConfigurableListableBeanFactory beanFactory) throws BeansException {

    beanFactory.registerScope("request", new RequestScope());
    MockHttpServletRequest request = new MockHttpServletRequest();
    ServletRequestAttributes attributes = new ServletRequestAttributes(request);
    RequestContextHolder.setRequestAttributes(attributes);
}

Answer 1

BeanFactoryPostProcessor有缺陷，它只运行一次，因此只有单个线程才会有（不可重用的）mockHttpServletRequest。

将创建请求并将其存储在RequestContextHolder中的代码移动到@Before批注方法中，并在@After批注方法中清除RequestContextHolder。

@Before
public void init() {
    MockHttpServletRequest request = new MockHttpServletRequest();
    ServletRequestAttributes attributes = new ServletRequestAttributes(request);
    RequestContextHolder.setRequestAttributes(attributes);
}

@After
public void cleanUp() {
    RequestContextHolder.resetRequestAttributes();
}

您仍然需要BeanFactoryPostProcessor来注册RequestScope。
