我的 APIAuthorizationFilter 类是
My APIAuthorizationFilter class is
@Component
public class APIAuthorizationFilter implements Filter{
@Value("${hmac.secret.key}")
private String secretKey;
@Autowired
private UnauthorizedExceptionController exceptionController;
@Override
public void doFilter(ServletRequest sr, ServletResponse sr1, FilterChain fc) throws IOException, ServletException {
HttpServletRequest httpServletRequest = (HttpServletRequest) sr;
HttpServletResponse httpServletResponse = (HttpServletResponse) sr1;
try {
MultiReadHttpServletRequest multiReadRequest = new MultiReadHttpServletRequest(httpServletRequest);
String authorizationHeader = HmacUtil.getHeaderValue(httpServletRequest, "Authorization");
String username = HmacUtil.getUsernameFromDecodeBasicAuth(authorizationHeader);
String password = HmacUtil.getPasswordFromDecodeBasicAuth(authorizationHeader);
String passwordSecretKey = secretKey;
if (passwordSecretKey != null && !passwordSecretKey.isEmpty() && passwordSecretKey.length() > 0) {
if (password.equals(passwordSecretKey.split(",")[0])) {
final SignatureBuilder signatureBuilder = new SignatureBuilder()
.algorithm(HmacUtil.getAlgorithm())
.accessUser(username)
.accessPassword(password)
.method(httpServletRequest.getMethod())
.contentType(MediaType.APPLICATION_JSON)
.resource(HmacUtil.getPath(httpServletRequest))
.apiSecret(AESEncryption.decryptText(passwordSecretKey.split(",")[1]).getBytes())
.body(HmacUtil.getRequestBody(multiReadRequest));
String hmac = HmacUtil.getHeaderValue(httpServletRequest, "auth");
Logger.getLogger(SignatureBuilder.class.getName()).log(Level.INFO, "Signature " + hmac);
if (!signatureBuilder.isHashEquals(hmac.getBytes())) {
throw new UnauthorizedException("Cannot access this resource");
}
fc.doFilter(multiReadRequest, sr1);
} else {
throw new UnauthorizedException("Cannot access this resource");
}
} else {
throw new UnauthorizedException("Cannot access this resource");
}
} catch (Exception e) {
Logger.getLogger(APIAuthorizationFilter.class.getName()).log(Level.SEVERE, "Exception:: " + e.getMessage(), e);
httpServletResponse.setStatus(HttpStatus.UNAUTHORIZED.value());
httpServletResponse.setContentType("application/json");
httpServletResponse.getWriter().write(exceptionController.unauthorizedStringRes(new UnauthorizedException("Cannot access this resource")));
}
}
我要注册的 FilterBean 类是
My FilterBean class to register is
@Configuration
public class FilterBean {
@Bean
public FilterRegistrationBean registerFilter(APIAuthorizationFilter aPIAuthorizationFilter) {
FilterRegistrationBean<APIAuthorizationFilter> filterRegistrationBean = new FilterRegistrationBean<>();
filterRegistrationBean.setFilter(aPIAuthorizationFilter);
filterRegistrationBean.addUrlPatterns("/api/*");
return filterRegistrationBean;
}
}
推荐答案
我在 tomcat 8 中部署时遇到同样的错误.尝试在 tomcat 9 中部署.我认为 spring boot 2.2 需要 tomcat 9.
I got same error when deploying in tomcat 8.Try deploying in tomcat 9.I think spring boot 2.2 requires tomcat 9.
Spring boot 2.2.6 的默认嵌入 tomcat 也是 org.apache.tomcat.embed 9.0.33
Also Default embed tomcat of Spring boot 2.2.6 is org.apache.tomcat.embed 9.0.33
