在Tomcat上部署Spark Java

我想在tomcat上部署SparkJava。在web.xml中，我有

<filter>
        <filter-name>SparkFilter</filter-name>
        <filter-class>spark.servlet.SparkFilter</filter-class>
        <init-param>
            <param-name>RestCheckerService</param-name>
            <param-value>rest.RestCheckerService</param-value>
        </init-param>
    </filter>

    <filter-mapping>
        <filter-name>SparkFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

我的过滤类

public class RestCheckerService implements SparkApplication{
  ...

    @Override
    public void init() {
      ...

        Spark.get("/scheme/:groupName/:schemeName/:version", new Route() {
            @Override
            public Object handle(Request request, Response response) {
                try {
return gson.toJson(clientDB.getScheme(request.params(":groupName"), request.params(":schemeName"), Integer.parseInt(request.params(":version"))));

                } catch (DaoException e) {
                    return RestErrorCodes.ERROR;
                }
            }
        });

    }

可能是因为我使用了Java7而不是Java8

<param-name>RestCheckerService</param-name>

与

替换

<param-name>RestCheckerService</param-name>

与

你能给我们看一下SparkFilter类里面的内容吗？你能给我们看一下SparkFilter类里面的内容吗？

<param-name>applicationClass</param-name>
