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

<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-feign</artifactId>
</dependency>
<dependency>
<groupId>com.netflix.feign</groupId>
<artifactId>feign-okhttp</artifactId>
<version>8.18.0</version>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-oauth2</artifactId>
</dependency>
</dependencies>

调用端配置

1. 引入maven依赖

<dependency>
<groupId>com.liuzm.paascloud.common</groupId>
<artifactId>paascloud-security-feign</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>

1. @FeignClient加入configuration属性

/**
* The interface Mdc product feign api.
* @author paascloud.net@gmail.com
*/
@FeignClient(value = "paascloud-provider-mdc", configuration = OAuth2FeignAutoConfiguration.class, fallback = MdcProductFeignHystrix.class)
public interface MdcProductFeignApi {
/**
* Update product stock by id int.
*
* @param productDto the product dto
*
* @return the int
*/
@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 com.paascloud.security.core.properties.SecurityProperties;
import org.apache.commons.lang3.ArrayUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.oauth2.config.annotation.builders.InMemoryClientDetailsServiceBuilder;
import org.springframework.security.oauth2.provider.ClientDetails;
import org.springframework.security.oauth2.provider.ClientDetailsService;
import org.springframework.security.oauth2.provider.ClientRegistrationException;
import org.springframework.stereotype.Component;
import javax.annotation.PostConstruct;
/**
* The class Rest client details service.
*
* @author paascloud.net @gmail.com
*/
@Component("restClientDetailsService")
public class RestClientDetailsServiceImpl implements ClientDetailsService {
private ClientDetailsService clientDetailsService;
@Autowired
private SecurityProperties securityProperties;
/**
* Init.
*/
@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();
}
}
/**
* Load client by client id client details.
*
* @param clientId the client id
*
* @return the client details
*
* @throws ClientRegistrationException the client registration exception
*/
@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()));
}
}
