java - 拦截器在 Spring Boot GraphQL 中不起作用

Question

我正在使用 graphql-java-kickstart/graphql-spring-boot，我想创建一个拦截器以在处理请求后添加 HTTP header 。

当我向后端发送 graphql 请求时，拦截器没有被触发。但是有些调用会触发拦截器。例如，当我在浏览器中打开/graphiql 时，我看到拦截器被触发了，但是当我从 graphiql 客户端发送 graphql 请求时却没有。知道为什么吗？有人对此有经验吗？

我的配置是这样的:

@Configuration
public class InterceptorConfig implements WebMvcConfigurer {

    @Autowired
    private TestInterceptor testInterceptor;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(testInterceptor).addPathPatterns("/**");
    }
}

还有我的拦截器:

@Slf4j
@Component
public class TestInterceptor extends HandlerInterceptorAdapter {

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView)
            throws Exception {
        // post processing
        log.info("hello there");
    }

}

Answer 1

我有以下在我的项目中成功运行的拦截器:

1. 我的网络配置:

@Configuration
public class WebConfig implements WebMvcConfigurer {
    
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(requestInterceptor);
    }
    
    @Autowired
    private ControllerExecInterceptor requestInterceptor;
}

其中 ControllerExecInterceptor 定义为:

@Component
public class ControllerExecInterceptor extends HandlerInterceptorAdapter {
    
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws AccessDeniedException, Exception {
        // ...
    }

    @Override
    public boolean postHandle(HttpServletRequest request, HttpServletResponse 
                            response, Object handler) throws {
        // ...
    }
}
