Question

我目前遇到的问题是我的RestEasyClient在关闭响应对象后没有释放连接。在我的本地环境中它可以工作，但是当我部署到CentOS Tomcat 7实例时，连接在一段时间之后才会被释放。

以下是我如何初始化客户端的示例：

ResteasyClient client = new ResteasyClientBuilder().connectionPoolSize(20)
    .connectionTTL(2, TimeUnit.SECONDS)
    .establishConnectionTimeout(500, TimeUnit.MILLISECONDS)
    .maxPooledPerRoute(20)
    .build();

以下是使用客户端/消费响应的示例：

final ResteasyWebTarget target = client.target(url);
Response response = null;
try {
    response = target.request().post(Entity.json(postBody));
    final String jsonMsg = response.readEntity(String.class);
    return mapper.readValue(jsonMsg, new TypeReference<List<String>>() {});
} catch (final Exception e) {
    log.error("error", e);
} finally {
    if (null != response) {
        response.close();
    }
}

这是堆栈跟踪：

javax.ws.rs.ProcessingException: Unable to invoke request
    at org.jboss.resteasy.client.jaxrs.engines.ApacheHttpClient4Engine.invoke(ApacheHttpClient4Engine.java:287)
    at org.jboss.resteasy.client.jaxrs.internal.ClientInvocation.invoke(ClientInvocation.java:407)
    at org.jboss.resteasy.client.jaxrs.internal.ClientInvocationBuilder.post(ClientInvocationBuilder.java:195)

引起：

Caused by: org.apache.http.conn.ConnectionPoolTimeoutException: Timeout waiting for connection
    at org.apache.http.impl.conn.PoolingClientConnectionManager.leaseConnection(PoolingClientConnectionManager.java:232)
    at org.apache.http.impl.conn.PoolingClientConnectionManager$1.getConnection(PoolingClientConnectionManager.java:199)

    at org.jboss.resteasy.client.jaxrs.engines.ApacheHttpClient4Engine.invoke(ApacheHttpClient4Engine.java:283)

任何帮助都会非常感激 - 我已经在这个问题上花了好几天。
