资源服务器就是业务服务 如用户服务，订单服务等 第三方需要到资源服务器调用接口获取资源
ResourceServerConfig
ResourceServerConfig是资源服务器的核心配置 用于验证token 与网关配置相似
其中.antMatchers("/**").access("#oauth2.hasScope('user')") 需要oauth_client_details表的scope配合 意思是访问所有资源 需要客户端有scope需要有user

AuthExceptionEntryPointConfig,CustomAccessDeniedHandlerConfig
用于异常返回前端json

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
@Component public class CustomAccessDeniedHandlerConfig implements AccessDeniedHandler {
@Override public void handle(HttpServletRequest request, HttpServletResponse response, AccessDeniedException accessDeniedException) throws IOException, ServletException { response.setStatus(HttpStatus.OK.value()); response.setHeader( "Content-Type" , "application/json;charset=UTF-8" ); try { Result result = new Result( 403 , "权限不足" ); response.getWriter().write( new ObjectMapper().writeValueAsString(result)); } catch (IOException e) { e.printStackTrace(); } } } |

@Component public class AuthExceptionEntryPointConfig implements AuthenticationEntryPoint{

@Value ( "${security.redirect-url}" ) private String redirectUrl;
@Override public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException) { Throwable cause = authException.getCause(); response.setStatus(HttpStatus.OK.value()); response.setHeader( "Content-Type" , "application/json;charset=UTF-8" ); Result result; try { if (cause instanceof InvalidTokenException) { result = new Result( 402 , "认证失败,无效或过期token" ); response.getWriter().write( new ObjectMapper().writeValueAsString(result)); } else { result = new Result( 401 , "认证失败,没有携带token" ); response.sendRedirect(redirectUrl); }
} catch (IOException e) { e.printStackTrace(); } } } |
TokenConfig
不多说

@Configuration public class TokenConfig{
/** * 使用redis存储 */ @Autowired private RedisConnectionFactory redisConnectionFactory;
@Bean public TokenStore tokenStore() { return new RedisTokenStore(redisConnectionFactory); }
} |
application.yml
那么小伙伴又问了 既然网关验证token的有效性 那么资源服务器是不是就不用验证啦 答案是否 因为不添加配置 会报错 同样需要在application中添加以下配置
其他配置也spirng boot为准 这里不多说
