我现在注意到github链接.我相信您还需要为测试配置安全过滤器.像

I noticed the github link now. I believe you need to configure security filter also for your tests. Something like

 mockMvc = MockMvcBuilders.webApplicationContextSetup(webApplicationContext)
                .addFilter(springSecurityFilterChain)
                .build();

可能需要一些其他设置，您可以检查 http://www.petrikainulainen.net/programming/spring-framework/integration-testing-of-spring-mvc-applications-security/以获得启发.
