java - 必须在 servlet 上以及异步请求处理中涉及的所有过滤器上启用异步支持

标签 java spring jetty servlet-filters spring-websocket

我在 stackoverflow 上阅读了足够多的问题和答案，但没有人帮助我。 我尝试插入

<async-supported> true</async-supported>

到处都是，但这对我没有帮助，我还尝试用 @Async 注释我的自定义过滤器 注释没有任何结果。我正在使用 jetty 9.3.9.v20160517 ， Java servlet 依赖

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>4.0.1</version>
        <scope>provided</scope>
    </dependency>

另外，我连接了 spring websocket 配置，一切正常，但是当我尝试使用 SockJS 和 Stomp 通过前端建立与服务器的连接时，在服务器上我在 Google Chrome 的控制台中收到此错误:

以及这个 Java 异常:

Caused by: org.springframework.web.socket.sockjs.SockJsTransportFailureException: Failed to open session; nested exception is java.lang.IllegalArgumentException: Async support must be enabled on a servlet and for all filters involved in async request processing. This is done in Java code using the Servlet API or by adding "<async-supported>true</async-supported>" to servlet and filter declarations in web.xml. Also you must use a Servlet 3.0+ container

websocket配置

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig  implements WebSocketMessageBrokerConfigurer {
    @Autowired
    private ObjectMapper objectMapper;

    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.enableSimpleBroker("/topic");
        config.setApplicationDestinationPrefixes("/app");
    }

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/gs-guide-websocket").setAllowedOrigins("*").withSockJS();
    }

    @Override
    public void configureWebSocketTransport(WebSocketTransportRegistration webSocketTransportRegistration) {
        webSocketTransportRegistration.setSendTimeLimit(15 * 1000).setSendBufferSizeLimit(512 * 1024);
    }


    @Override
    public void configureClientOutboundChannel(ChannelRegistration channelRegistration) {
        channelRegistration.taskExecutor().corePoolSize(4).maxPoolSize(10);
    }


    @Override
    public boolean configureMessageConverters(List<MessageConverter> list) {
        DefaultContentTypeResolver resolver = new DefaultContentTypeResolver();
        resolver.setDefaultMimeType(MimeTypeUtils.APPLICATION_JSON);
        MappingJackson2MessageConverter converter = new MappingJackson2MessageConverter();
        converter.setObjectMapper(objectMapper);
        converter.setContentTypeResolver(resolver);
        list.add(converter);
        return false;
    }

最佳答案 

    <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>false</param-value>
        </init-param>
    </filter>

该过滤器丢失 <async-supported>true</async-supported> .

看到您对该过滤器的映射是......

    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>ASYNC</dispatcher>
    </filter-mapping>

这意味着 100% 的请求都会通过它，这意味着即使您的某个 servlet 启用了异步支持，它也必须启用异步支持。

关于java - 必须在 servlet 上以及异步请求处理中涉及的所有过滤器上启用异步支持，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/54695516/
