### spring security oauth2 github 用户权限（GrantedAuthoritiesMapper） ###

**应用：为三方授权用户设置自定义的权限**

**相关类及接口**

**默认权限设置**

**DefaultOAuth2UserService：获取用户信息的默认实现类，同时为三方用户添加权限**

**OAuth2UserAuthority：用户权限类**

            this("ROLE_USER", attributes);
        }  //authority的值默认为ROLE_USER
    
        public OAuth2UserAuthority(String authority, Map<String, Object> attributes) {
            Assert.hasText(authority, "authority cannot be empty");
            Assert.notEmpty(attributes, "attributes cannot be empty");
            this.authority = authority;
            this.attributes = Collections.unmodifiableMap(new LinkedHashMap(attributes));
        }
    
        public String getAuthority() {
        public Map<String, Object> getAttributes() {
    
        public boolean equals(Object obj) {
        public int hashCode() {
    
        public String toString() {
            return this.getAuthority();
        }
    }

**\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\***

**自定义用户权限**

**GrantedAuthoritiesMapper：自定义权限类接口**

public interface GrantedAuthoritiesMapper {
        Collection<? extends GrantedAuthority> mapAuthorities(Collection<? extends GrantedAuthority> var1);
    }

### \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* ###

**示例**

**\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\***

**controller 层**

**HelloController**

@RestController
    public class HelloController {
     
        @RequestMapping("/hello")
        public String hello(Principal principal){
            System.out.println(principal.toString());
     
            return "hello "+principal.getName();
        }
     
        @RequestMapping("/")
        public String redirect(){
            return "redirect";
        }
    }
