我正在寻找在Spring Security 3中制作自定义UserDetails对象的示例。
我希望有人能帮助，谢谢。

请您参考如下方法:

这是我使用的:

public class CustomUserDetails implements UserDetails { 
    private  User user; 
 
    public CustomUserDetails(final User _user) { 
            this.user = _user; 
    } 
 
    public CustomUserDetails() { 
    } 
 
    @Override 
    public Collection<GrantedAuthority> getAuthorities() { 
             final Set<GrantedAuthority> _grntdAuths = new HashSet<GrantedAuthority>(); 
 
     List<UserRole> _roles = null; 
 
     if (user!=null) { 
             _roles = user.getRoles(); 
     } 
 
     if (_roles!=null) { 
             for (UserRole _role : _roles) { 
                     _grntdAuths.add(new GrantedAuthorityImpl(_role.getRole())); 
             } 
     } 
 
     return _grntdAuths; 
    } 
 
    @Override 
    public String getPassword() { 
            return user.getPassword(); 
    } 
 @Override 
    public String getUsername() { 
            if (this.user == null) { 
                    return null; 
            } 
            return this.user.getUser_name(); 
    } 
 
    @Override 
    public boolean isAccountNonExpired() { 
            return this.user.isAccountNonExpired(); 
    } 
 
    @Override 
    public boolean isAccountNonLocked() { 
            return this.user.isAccountNonLocked(); 
    } 
 
    @Override 
    public boolean isCredentialsNonExpired() { 
            return this.user.isCredentialsNonExpired(); 
    } 
 
    @Override 
    public boolean isEnabled() { 
            return this.user.isEnabled(); 
    } 
 
    public User getUser() { 
            return user; 
    } 
 
    @Override 
    public String toString() { 
            return "CustomUserDetails [user=" + user + "]"; 
    } 
}
