Spring mvc Spring MockMvc不期望内容

我正在尝试测试一个thymeleaf模板，该模板根据用户的spring安全角色返回内容

我希望检查一些内容是否不存在

@Autowired
private MockMvc mockMvc;

---

这可能吗？

一种解决方案是使用hamcrests CoreMatchers。而不是。。。。方法：

@Test
@WithMockUser(roles = "USER")
public void loginWithRoleUserThenExpectUserSpecificContent() throws Exception {
    mockMvc.perform(get("/index"))
            .andExpect(status().isOk())
            .andExpect(content().string(containsString("This content is only shown to users.")))
            .andExpect(content().string(doesNotContainString("This content is only shown to administrators.")));
}

private Matcher<String> doesNotContainString(String s) {
    return CoreMatchers.not(containsString(s));
}

@Test
@WithMockUser(roles = "USER")
public void loginWithRoleUserThenExpectUserSpecificContent() throws Exception {
    mockMvc.perform(get("/index"))
            .andExpect(status().isOk())
            .andExpect(content().string(containsString("This content is only shown to users.")))
            .andExpect(content().string(doesNotContainString("This content is only shown to administrators.")));
}

private Matcher<String> doesNotContainString(String s) {
    return CoreMatchers.not(containsString(s));
}
