在Spring 3.2上尝试使用RestTemplate POST对象时,平均响应时间为8秒
使用curl
time curl -X POST -H "Content-Type: application/xml" -T request.xml https://x.y.com:20000/rest
平均时间约为4秒。我不明白为什么。
我的配置:
<bean id="jaxb2Marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
<property name="classesToBeBound">
<list>
<value>x.y.z.Request</value>
<value>x.y.z.Response</value>
<value>x.y.z.AnotherRequest</value>
<value>x.y.z.AnotherResponse</value>
</list>
</property>
</bean>
<bean id="restTemplate" class="org.springframework.web.client.RestTemplate"
scope="prototype">
<constructor-arg>
<bean
class="org.springframework.http.client.HttpComponentsClientHttpRequestFactory">
<property name="readTimeout" value="${application.urlReadTimeout}" />
<property name="connectTimeout" value="${application.urlConnectionTimeout}" />
</bean>
</constructor-arg>
<property name="messageConverters">
<list>
<bean
class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter">
<property name="marshaller" ref="jaxb2Marshaller" />
<property name="unmarshaller" ref="jaxb2Marshaller" />
</bean>
<bean class="org.springframework.http.converter.FormHttpMessageConverter" />
<bean
class="org.springframework.http.converter.StringHttpMessageConverter" />
</list>
</property>
</bean>
然后我简单地自动装配它:
@Autowired
RestTemplate restTemplate;
public Response getXml(Request request){
Response response = restTemplate.postForObject(httpUrl,request, Response.class);
}
P.S:作为替代方案,我尝试使用JaxB解析Request / Response对象,并使用org.apache.http.client.HttpClient
发送它,平均时间约为7秒,这远远不够好。
答案 0 :(得分:1)
可能是ipv4 / 6问题。试试
curl -4 -X POST -H "Content-Type: application/xml" -T request.xml https://x.y.com:20000/rest
如果它适合您,请使用param运行您的java cmd
-Djava.net.preferIPv4Stack=true
