使用自定义 UserDetails 实现测试 Spring Security 和 MvcMock

我正在尝试按照这篇文章 [1] 在我的 Spring Mvc 模拟测试中模拟安全性。

我想要测试的 REST 服务如下所示：

@RequestMapping(value = "/something/{id}", method = RequestMethod.DELETE)
public ResponseEntity<Void> deleteXXX(@ActiveUser AppUser user, @PathVariable(value = "id") Long id) {
  ...
}

where @ActiveUser是一个自定义实现/扩展@AuthenticationPrincipal and AppUser是习俗UserDetails执行。

在测试中我这样做：

mockMvc.perform(delete("/something/{i}", "123").with(user(new AppUser(...))));

我还添加了一些TestExecutionLIsteners:

@TestExecutionListeners(listeners = { ServletTestExecutionListener.class, DependencyInjectionTestExecutionListener.class, DirtiesContextTestExecutionListener.class, TransactionalTestExecutionListener.class, WithSecurityContextTestExecutionListener.class })

```

但它失败了：

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [com.corp.AppUser]: No default constructor found; nested exception is java.lang.NoSuchMethodException: com.corp.AppUser.<init>()
at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:973)
at org.springframework.web.servlet.FrameworkServlet.doDelete(FrameworkServlet.java:885)

这是可以的，因为AppUser没有默认的构造函数，但框架实际上不应该创建用户，而是使用我传递到测试中的用户。

为了在运行时解决这个问题，我必须添加AuthenticationPrincipalArgumentResolver as a HandlerMethodArgumentResolver到网络配置，但我如何在测试用例中做到这一点？

有这方面的工作示例吗？

edit:

测试类及其配置如下所示：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { MyControllerTest.DummyAppConfig.class,  MyControllerTest.DummySecurityConfiguration.class })
@TestExecutionListeners(listeners = { ServletTestExecutionListener.class, DependencyInjectionTestExecutionListener.class, DirtiesContextTestExecutionListener.class, TransactionalTestExecutionListener.class, WithSecurityContextTestExecutionListener.class })
@WebAppConfiguration
public class MyControllerTest {


@Test
public void doTest() throws Exception {
    mockMvc.perform(delete("/something/{i}", "123").with(user(new AppUser(...))));
}


@Configuration
public static class DummyAppConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers) {
        argumentResolvers.add(new AuthenticationPrincipalArgumentResolver());
}

    @Bean
    public MyController aController() {
        return new MyController();
    }

}

@Configuration
@EnableWebSecurity
public static class DummySecurityConfiguration extends WebSecurityConfigurerAdapter {
}

```

这是完整的堆栈跟踪：

如果您使用MockMvcBuilders.standaloneSetup()方法，您可以将解析器添加到独立的 MockMvc 中，如下所示：

MockMvcBuilders.standaloneSetup(controller).setCustomArgumentResolvers(new AuthenticationPrincipalArgumentResolver()).build()

我也是，很难让它与MockMvcBuilders.webAppContextSetup()方法，但独立工作无需担心。
