模拟 @AuthenticationPrincipal 参数

Question

我有 spring-security-oauth2 应用程序，它是一个资源服务器。我们有一个自定义PrincipalExtractor类来构建自定义主体对象。此自定义主体对象不会扩展Principal或UserDetails

class CustomUser{
//some custom fields
}

class CustomPrincipalExtractor implements PrincipalExtractor{
  @Override 
  public CustomUser extractPrincipal(Map<String, Object> map){
    return new CustomUser(map);
  }
}


class SomeController{
  @GetMapping
  public ResponseEntity(@AuthenticationPrincipal CustomUser user){
     //able to get user object 
  }
}

上面的代码工作正常。现在我想测试控制器，但无法传递 CustomUser 实例。

@SpringBootTest
@AutoConfigureMockMvc
public class SomeControllerTest{
   @Autowired
   private MockMvc mockMvc;

  @Test
  public void test(){
    mockMvc.perform(get(...).principal(CANNOT pass CustomUser as it does not implement Principal))
  }
}

我查看了一些其他要求自定义HandlerMethodArgumentResolver但不确定如何配置自动配置的 MockMvc 的解决方案

Answer 1

我必须实施一些解决方法才能完成这项工作。

创建了一个模拟过滤器，用于在 SecurityContext 中设置 Authentication 对象。以下是代码

public class MockSpringSecurityFilter implements Filter {
  @Override
  public void init(FilterConfig filterConfig) {}

  @Override
  public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
    SecurityContextHolder.getContext()
      .setAuthentication((Authentication) ((HttpServletRequest) req).getUserPrincipal());
    chain.doFilter(req, res);
  }

  @Override
  public void destroy() {
    SecurityContextHolder.clearContext();
  }
}

测试内

@Before
public void setup() {
  mockMvc = MockMvcBuilders.webAppContextSetup(context)
    .apply(springSecurity(new MockSpringSecurityFilter()))
    .build();
}

@Test
  public void test(){
    mockMvc.perform(get(...)
     .principal(new UsernamePasswordAuthenticationToken(new CustomUser(), null))...
  }
