Spring Security / Spring Boot-如何为用户设置ROLES

创建UserDetails时，您应该自己填写角色的内容：

public class SecurityUser implements UserDetails{    String ROLE_PREFIX = "ROLE_";    String userName;    String password;    String role;    public SecurityUser(String username, String password, String role){        this.userName = username;        this.password = password;        this.role = role;    }    @Override    public Collection<? extends GrantedAuthority> getAuthorities() {        List<GrantedAuthority> list = new ArrayList<GrantedAuthority>();        list.add(new SimpleGrantedAuthority(ROLE_PREFIX + role));        return list;    }

基本上，您需要做的是重写方法：

getAuthorities

GrantedAuthority
