这篇文章将为大家详细讲解有关Spring Security OAuth2 token权限隔离的示例分析，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。
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",
"phone": "13918438965",

"authorities": []
}二、如何重写？
principal是OAuth3Authentication实例，OAuth3Authentication主要包括OAuth3Request 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OAuth3Authentication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));
OAuth3Authentication oAuth3Authentication = (OAuth3Authentication) principal;
OAuth3Request storedRequest = oAuth3Authentication.getOAuth3Request();
Authentication userAuthentication = oAuth3Authentication.getUserAuthentication();
// 为了服务端进行token权限隔离 定制OAuth3Authentication
CustomOAuth3Authentication customOAuth3Authentication = new CustomOAuth3Authentication(storedRequest, userAuthentication, storedRequest.getAuthorities());
customOAuth3Authentication.setDetails(oAuth3Authentication.getDetails());
log.info("返回用户信息:{}", JSON.toJSON(customOAuth3Authentication));
return customOAuth3Authentication;
}CustomOAuth3Authentication ：
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.oauth3.provider.OAuth3Request;
import java.util.Collection;
/**
* @author maxianming
* @date 2018/10/29 13:53
*/
public class CustomOAuth3Authentication extends AbstractAuthenticationToken {
private static final long serialVersionUID = -4809832298438307309L;
private final OAuth3Request 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).
* @param userAuthentication The user authentication (possibly null).
*/
public CustomOAuth3Authentication(OAuth3Request storedRequest, Authentication userAuthentication, Collection<? extends GrantedAuthority> authorities) {
/**
* 为了服务端进行token权限隔离 {@link @PreAuthorize("hasAuthority('server')")}，自定义OAuth3Authentication使得支持改变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 OAuth3Request getOAuth3Request() {
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 CustomOAuth3Authentication)) {
return false;
}
if (!super.equals(o)) {
return false;
}
CustomOAuth3Authentication that = (CustomOAuth3Authentication) 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OAuth3Authentication基础上修改了30-35行代码
