Question

我正在尝试实现JSR注释来处理缓存。经过大量的研究和SO的几个问题，我得到了以下几点。当我尝试运行它但它说

java.lang.RuntimeException: java.lang.ClassCastException: org.apache.tomcat.websocket.server.WsServerContainer cannot be cast to io.undertow.websockets.jsr.ServerWebSocketContainer Caused by: java.lang.RuntimeException: java.lang.ClassCastException: org.apache.tomcat.websocket.server.WsServerContainer cannot be cast to io.undertow.websockets.jsr.ServerWebSocketContainer Caused by: java.lang.ClassCastException: org.apache.tomcat.websocket.server.WsServerContainer cannot be cast to io.undertow.websockets.jsr.ServerWebSocketContainer"}}

我在这里做错了什么？

HelloService.java

@Path("/helloservice")
@EnableCaching
public class HelloService extends CachingSetup{

    @GET
    @Path("/unsecured")
    @Produces({"text/plain"})
    @CacheResult
    public String testUnsecured(){
        return "Unsecured user";
    }
}

CachingSetup.java

import static java.util.concurrent.TimeUnit.SECONDS;
import javax.cache.CacheManager;
import javax.cache.configuration.MutableConfiguration;
import javax.cache.expiry.Duration;
import javax.cache.expiry.TouchedExpiryPolicy;
import org.springframework.boot.autoconfigure.cache.JCacheManagerCustomizer;
import org.springframework.stereotype.Component;

  @Component
  public class CachingSetup implements JCacheManagerCustomizer
  {
    @Override
    public void customize(CacheManager cacheManager)
    {
      cacheManager.createCache("basicCache", new MutableConfiguration<>()  
        .setExpiryPolicyFactory(TouchedExpiryPolicy.factoryOf(new Duration(SECONDS, 10))) 
        .setStoreByValue(false)
        .setStatisticsEnabled(true));
    }
  }

ehcache.xml中

<config
    xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
    xmlns='http://www.ehcache.org/v3'  
    xmlns:jsr107='http://www.ehcache.org/v3/jsr107'>  

  <service>
    <jsr107:defaults>
      <jsr107:cache name="basicCache" template="heap-cache"/> 
    </jsr107:defaults>
  </service>

  <cache-template name="heap-cache">
    <listeners>    
      <listener>

Answer 1

感谢来自@ R.C的链接。上面我发现我需要修改我的pom.xml以删除默认的Spring tomcat实现

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-web</artifactId> 
</dependency>

需要：

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-web</artifactId> 

<exclusions>
    <exclusion>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
    </exclusion>
</exclusions>
</dependency>

我还添加了

<packaging>war</packaging>

位于顶部版本标记的正下方，使其看起来像：

<groupId>com.sentiment360</groupId>
<artifactId>QuteeDemoRest</artifactId>
<version>v1</version>
<packaging>war</packaging>

<name>QuteeDemoRest</name>

如何让Spring使用WildFly而不是Tomcat？
