为了在单元测试中使用请求和会话范围，您需要：

• 在应用程序上下文中注册这些范围
• 创建模拟会话并请求
• 通过注册模拟请求 RequestContextHolder

这样的事情（假设您使用Spring TestContext运行测试） abstractSessionTest.xml：

<beans ...>
    <bean class="org.springframework.beans.factory.config.CustomScopeConfigurer">
        <property name="scopes">
            <map>
                <entry key="session">
                    <bean class="org.springframework.web.context.request.SessionScope" />
                </entry>
                <entry key="request">
                    <bean class="org.springframework.web.context.request.RequestScope" />
                </entry>
            </map>
        </property>
    </bean>
</beans>

。

@ContextConfiguration("abstractSessionTest.xml")
public abstract class AbstractSessionTest {
    protected MockHttpSession session;
    protected MockHttpServletRequest request;

    protected void startSession() {
        session = new MockHttpSession();
    }

    protected void endSession() {
        session.clearAttributes();
        session = null;
    }

    protected void startRequest() {
        request = new MockHttpServletRequest();
        request.setSession(session);
        RequestContextHolder.setRequestAttributes(new ServletRequestAttributes(request));
    }

    protected void endRequest() {
        ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).requestCompleted();
        RequestContextHolder.resetRequestAttributes();
        request = null;
    }
}

现在，您可以在测试代码中使用以下方法：

startSession();
startRequest();
// inside request
endRequest();
startRequest();
// inside another request of the same session
endRequest();
endSession();
