我有一个只能从特定 IP 地址调用的 Web 应用程序。除此之外，不需要身份验证或授权；如果您来自正确的 IP，您可以看到所有内容。
为此，我搜索了 StackOverflow 和其他地方，发现了一些关于在 Spring Security 中按 IP 地址过滤请求的建议。它们都采用这种形式(使用 java 配置扩展 WebSecurityConfigurerAdapter):
http.authorizeRequests().anyRequest().access("hasIpAddress('127.0.0.1/0')");
但是，这对我没有用；它从不拒绝任何请求，无论我从哪个 IP 地址发出请求。相反，我使用如下自定义过滤器实现了 IP 过滤:
@Configuration
@EnableWebSecurity
@PropertySource("classpath:config.properties")
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
private static final Logger logger = LoggerFactory.getLogger(SecurityConfig.class);
@Autowired
private Environment env;
@Override
protected void configure(HttpSecurity http) throws Exception {
String ipRange = env.getRequiredProperty("trusted_ips");
logger.info("@@@@@ SETTING UP SECURITY CONFIGURATION @@@@@@@@@@@@@");
logger.info("@@ trusted_ips: " + ipRange);
logger.info("@@@@@ SETTING UP SECURITY CONFIGURATION - END @@@@@@@@@@@@@");
http.addFilterBefore(new IPSecurityFilter(ipRange), J2eePreAuthenticatedProcessingFilter.class)
.authorizeRequests().antMatchers("/**").permitAll();
}
}
我的 IPSecurityFilter:
public class IPSecurityFilter extends OncePerRequestFilter {
private static final Logger logger = LoggerFactory.getLogger(IPSecurityFilter.class);
private String[] ipAddresses;
public IPSecurityFilter(String strIPAddresses) {
logger.info("@@@@ Our IP Address whitelist: " + strIPAddresses);
this.ipAddresses = strIPAddresses.split(",");
}
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
logger.info("Checking whether request should be allowed: " + request.getRequestURI());
logger.info("@@@ Request is coming from IP address: " + request.getRemoteAddr());
for (String ipAddress : ipAddresses) {
if (ipAddress.equals(request.getRemoteAddr())) {
logger.info("@@@ Allowing request from ip address: " + request.getRemoteAddr());
return; // We accept requests from this IP address
}
}
// The remote IP address isn't on our white list; throw an exception
throw new AccessDeniedException("Access has been denied for your IP address: " + request.getRemoteAddr());
}
}
这似乎有效，因为如果请求来自不在我的白名单中的 IP 地址，请求将被拒绝。
但是，使用此配置，我的单元(使用 MockMvc)测试失败；它以我从未预料到的方式失败了。单元测试运行时，似乎正确使用了Spring Security配置，请求通过了安全测试(IP白名单包括127.0.0.1，根据测试运行时产生的日志，请求来了来自那个IP)。但是，请求似乎从未路由到我的 Controller 。
这是我的测试:
@RunWith(SpringRunner.class)
@WebMvcTest()
//@WebMvcTest(value = HandlerController.class)
@AutoConfigureMockMvc
@Import(SecurityConfig.class)
public class HandlerControllerTest {
@Autowired
private MockMvc mvc;
@Test
public void getIndex() throws Exception {
mvc.perform(MockMvcRequestBuilders.get("/").accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(content().json("{\"services\":[\"OutboundMessageService\"]}", true));
}
}
最后，这是我的 Controller (请忽略我生成 JSON 返回值的愚蠢方式，它仍处于开发初期):
@RestController
public class HandlerController {
private static final Logger logger = LoggerFactory.getLogger(HandlerController.class);
@RequestMapping("/")
public String index() {
logger.info("### handling a request for / ###");
return "{\"services\":[\"OutboundMessageService\"]}";
}
}
测试结果如下:

从日志消息中可以看出，正在调用 IP 过滤器并允许请求继续。但是，在我的处理程序中发出的调试字符串无处可见，返回正文为空白。谁能告诉我为什么我的安全过滤器会阻止 MockMvc 将其请求成功路由到我的 Controller ？
最后注意:如果我使用 http.authorizeRequests().anyRequest().access("hasIpAddress('127.0.0.1/0')");我首先列出的配置或通过删除我的 SecurityConfig 类完全摆脱 Spring Security，请求成功路由到我的处理程序。
最佳答案
我想出了如何使测试工作。我找不到一篇文章来回答我的问题，但通过从多篇博文中采纳不同的建议，我想出了一个对我有用的文章:
@RunWith(SpringRunner.class)
@WebMvcTest(controllers = HandlerController.class)
public class HandlerControllerTest {
private MockMvc mvc;
@Autowired
private WebApplicationContext webApplicationContext;
@Before
public void setUp() {
// mvc = MockMvcBuilders.standaloneSetup(new HandlerController()).build();
mvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
}
@Test
public void getIndex() throws Exception {
mvc.perform(get("/").accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(content().json("{\"services\":[\"OutboundMessageService\"]}", true));
}
@Test
public void getMessageService() throws Exception {
mvc.perform(get("/OutboundMessageService").accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(content().json("{\"status\": \"SUCCESS\"}", true));
}
}
如您所见，我不再自动连接 MockMvc 对象并允许它自动设置，而是我自己在 setUp() 方法中设置它。 setUp() 方法中的注释行也可以成功测试我的 Controller ，但它不会通过我的 Spring Security IP 地址过滤器路由请求。我将其保留下来，以便不需要测试 Spring Security 的用户可以看到另一种设置 MockMvc 对象的方法。未注释的行设置了一个 MockMvc 对象，以便它通过安全过滤器和我的 Controller 运行请求。
关于java - 在 Spring Security 中使用自定义过滤器时，Spring 单元测试 MockMvc 失败，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/47290024/
