spring cloud oauth2 feign 遇到的坑
关于oauth2相关的内容这里不重复描述，在spring cloud中在管理内部api时鉴权相信有很多人会有疑问，这里描述两种比较low的用法，由于公司内部使用的是阿里云edas这里仅仅是记录一下，如果有更好的用法在请赐教，不喜勿喷！
客户端模式
提供三方jar包
这里需要抽一个jar包,需要用到feign的为服务端直接利用maven模式引入feign即可

}调用端配置
引入maven依赖
<dependency>
<groupId>com.liuzm.paascloud.common</groupId>
<artifactId>paascloud-security-feign</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>@FeignClient加入configuration属性
@FeignClient(value = "paascloud-provider-mdc", configuration = OAuth2FeignAutoConfiguration.class, fallback = MdcProductFeignHystrix.class)
public interface MdcProductFeignApi {
@RequestMapping(value = "/api/product/updateProductStockById", method = RequestMethod.POST)
int updateProductStockById(@RequestBody ProductDto productDto);
}认证服务器配置
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients.withClientDetails(restClientDetailsService);
}package com.paascloud.provider.security;
import com.paascloud.security.core.properties.OAuth2ClientProperties;

import org.springframework.security.oauth2.provider.ClientDetails;
import org.springframework.security.oauth2.provider.ClientDetailsService;
import org.springframework.security.oauth2.provider.ClientRegistrationException;

@Component("restClientDetailsService")
public class RestClientDetailsServiceImpl implements ClientDetailsService {
private ClientDetailsService clientDetailsService;
@Autowired
private SecurityProperties securityProperties;
@PostConstruct
public void init() {
InMemoryClientDetailsServiceBuilder builder = new InMemoryClientDetailsServiceBuilder();
if (ArrayUtils.isNotEmpty(securityProperties.getOauth2().getClients())) {
for (OAuth2ClientProperties client : securityProperties.getOauth2().getClients()) {
builder.withClient(client.getClientId())
.secret(client.getClientSecret())
.authorizedGrantTypes("refresh_token", "password", "client_credentials")
.accessTokenValiditySeconds(client.getAccessTokenValidateSeconds())
.refreshTokenValiditySeconds(2592000)
.scopes(client.getScope());
}
}
try {
clientDetailsService = builder.build();
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public ClientDetails loadClientByClientId(String clientId) throws ClientRegistrationException {
return clientDetailsService.loadClientByClientId(clientId);
}
}bootstrap.yml配置
security:
oauth2:
tokenStore: jwt
clients[0]:
clientId: paascloud-client-uac
clientSecret: paascloudClientSecret
accessTokenValidateSeconds: 7200
scope: "*"
clients[1]:
clientId: paascloud-browser
clientSecret: paascloudClientSecret
accessTokenValidateSeconds: 7200
scope: "*"
clients[2]:
clientId: paascloud-client-gateway
clientSecret: paascloudClientSecret
accessTokenValidateSeconds: 7200
scope: "*"
clients[3]:
clientId: paascloud-client-zipkin
clientSecret: paascloudClientSecret
accessTokenValidateSeconds: 7200
scope: "*"
clients[4]:
clientId: paascloud-client-mdc
clientSecret: paascloudClientSecret
accessTokenValidateSeconds: 7200
scope: "*"
clients[5]:
clientId: paascloud-client-omc
clientSecret: paascloudClientSecret
accessTokenValidateSeconds: 7200
scope: "*"
clients[6]:
clientId: paascloud-client-opc
clientSecret: paascloudClientSecret
accessTokenValidateSeconds: 7200
scope: "*"到此客户端模式配置完成!
基于spring security
开放权限,利用url规范来规划客户端的url不通过auth2鉴权,这里唯一的区别是在feign拦截器里处理的逻辑改一下，代码如下
@Autowired
private OAuth2ClientContext context;
@Override
public void apply(RequestTemplate template) {
if(context.getAccessToken() != null && context.getAccessToken().getValue() != null && OAuth2AccessToken.BEARER_TYPE.equalsIgnoreCase(context.getAccessToken().getTokenType()) ){
template.header("Authorization", String.format("%s %s", OAuth2AccessToken.BEARER_TYPE, context.getAccessToken().getValue()));
}
}spring cloud微服务增加oauth2权限后 feign调用报null
在授权服务里，用户通过用户名密码，或者手机和验证码等方式登陆之后，在http头里会有授权的标识，在客户端调用时，需要添加当时有效的token才可以正常访问被授权的页面。
Content-Type:application/json
Authorization:Bearer d79c064c-8675-4047-a119-fac692e447e8而在业务层里，服务与服务之间使用feign来实现调用，而授权的代码我们可以通过拦截器实现，在feign请求之前，把当前服务的token添加到目标服务的请求头就可以了
一般是这样实现的
@Component
public class TokenFeignClientInterceptor implements RequestInterceptor {
@Override
public void apply(RequestTemplate requestTemplate) {
RequestAttributes requestAttributes = RequestContextHolder.currentRequestAttributes();
if (requestAttributes != null) {
HttpServletRequest request = ((ServletRequestAttributes) requestAttributes).getRequest();
requestTemplate.header("Authorization", request.getHeader("Authorization"));
}
}
}上面的拦截器代码没有什么问题，也很好理解，但事实上，当你的feign开启了hystrix功能，如果开启了，需要把hystrix的策略进行修改，默认是THREAD的，这个级别时ThreadLocal是空的，所以你的授权不能传给feign的拦截器.
hystrix:
command:
default:
execution:
isolation:
strategy: SEMAPHORE 以上为个人经验，希望能给大家一个参考，也希望大家多多支持编程网。
