这篇文章主要介绍了Spring Security OAuth2 token权限隔离实例解析,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
由于项目OAuth2采用了多种模式，授权码模式为第三方系统接入，密码模式用于用户登录，Client模式用于服务间调用，
所有不同的模式下的token需要用 @PreAuthorize("hasAuthority('client')") 进行隔离，遇到问题一直验证不通过。
通过调试发现资源服务从授权服务拿到的authrities字段一直为空， StackOverFlow说低版本（项目中才2.0.15）的OAuth2实现权限隔离需要 重写UserInfoTokenService
但是资源服务太多所以考虑重写授权服务的返回值，如何重写？在哪里重写？是下面要介绍的~
一、哪里重写？
资源服务器向授权服务服务器获取资源时候，返回的user信息重写，加入authorities
@RestController
@Slf4j
public class UserController {
@Autowired
HttpServletRequest request;
@GetMapping("/user")
public Principal user(Principal principal) {
log.info("获取user信息:{}", JSON.toJSON(principal)); return principal; }
返回的具体用户信息：
{
"principal": {
"password": "$2a$10$OjTFAZEzS6qypY4nRZtnM.MzS6F3XsIlkAO/kIFCu30kAk8Yasowa",

},
"authorities": []
}
二、如何重写？
principal是OAuth2Authentication实例，OAuth2Authentication主要包括OAuth2Request storedRequest、Authentication userAuthentication，
重写目的是将storedRequest authorities复制到authoritie中，但问题是authoritie不让修改的，没办法只能重写这个OAuth2Authentication了。
为了改变authoritie重写：
@GetMapping("/user")
public Principal user(Principal principal) {
log.info("获取user信息:{}", JSON.toJSON(principal));
OAuth2Authentication oAuth2Authentication = (OAuth2Authentication) principal;
OAuth2Request storedRequest = oAuth2Authentication.getOAuth2Request();
Authentication userAuthentication = oAuth2Authentication.getUserAuthentication();
// 为了服务端进行token权限隔离 定制OAuth2Authentication
CustomOAuth2Authentication customOAuth2Authentication = new CustomOAuth2Authentication(storedRequest, userAuthentication, storedRequest.getAuthorities());
customOAuth2Authentication.setDetails(oAuth2Authentication.getDetails());
log.info("返回用户信息:{}", JSON.toJSON(customOAuth2Authentication));
return customOAuth2Authentication;
}
CustomOAuth2Authentication ：
package com.brightcns.wuxi.citizencard.auth.domain;
import org.springframework.security.authentication.AbstractAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.CredentialsContainer;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.oauth2.provider.OAuth2Request;
import java.util.Collection;
/**

public class CustomOAuth2Authentication extends AbstractAuthenticationToken {
private static final long serialVersionUID = -4809832298438307309L;
private final OAuth2Request storedRequest;
private final Authentication userAuthentication;
/**
* Construct an OAuth 2 authentication. Since some grant types don't require user authentication, the user
* authentication may be null.
* @param storedRequest The authorization request (must not be null).

*/
public CustomOAuth2Authentication(OAuth2Request storedRequest, Authentication userAuthentication, Collection<? extends GrantedAuthority> authorities) {
/**

*/
super(authorities != null ? authorities : userAuthentication == null ? storedRequest.getAuthorities() : userAuthentication.getAuthorities());
this.storedRequest = storedRequest;
this.userAuthentication = userAuthentication;
}
public Object getCredentials() {
return "";
}
public Object getPrincipal() {
return this.userAuthentication == null ? this.storedRequest.getClientId() : this.userAuthentication
.getPrincipal();
}
/**
* Convenience method to check if there is a user associated with this token, or just a client application.
*
* @return true if this token represents a client app not acting on behalf of a user
*/
public boolean isClientOnly() {
return userAuthentication == null;
}
/**
* The authorization request containing details of the client application.
*
* @return The client authentication.
*/
public OAuth2Request getOAuth2Request() {
return storedRequest;
}
/**
* The user authentication.
*
* @return The user authentication.
*/
public Authentication getUserAuthentication() {
return userAuthentication;
}
@Override
public boolean isAuthenticated() {
return this.storedRequest.isApproved()
&& (this.userAuthentication == null || this.userAuthentication.isAuthenticated());
}
@Override
public void eraseCredentials() {
super.eraseCredentials();
if (this.userAuthentication != null && CredentialsContainer.class.isAssignableFrom(this.userAuthentication.getClass())) {
CredentialsContainer.class.cast(this.userAuthentication).eraseCredentials();
}
}
@Override
public boolean equals(Object o) {
if (this == o) {
return true;
}
if (!(o instanceof CustomOAuth2Authentication)) {
return false;
}
if (!super.equals(o)) {
return false;
}
CustomOAuth2Authentication that = (CustomOAuth2Authentication) o;
if (!storedRequest.equals(that.storedRequest)) {
return false;
}
if (userAuthentication != null ? !userAuthentication.equals(that.userAuthentication)
: that.userAuthentication != null) {
return false;
}
if (getDetails() != null ? !getDetails().equals(that.getDetails()) : that.getDetails() != null) {
// return false;
}
return true;
}
@Override
public int hashCode() {
int result = super.hashCode();
result = 31 * result + storedRequest.hashCode();
result = 31 * result + (userAuthentication != null ? userAuthentication.hashCode() : 0);
return result;
}
}
主要在OAuth2Authentication基础上修改了30-35行代码
