Question

我遇到了休息模板交换方法的问题。我用它将请求发送到谷歌的GCM服务器。每次相同的请求，只有收件人不同（JSON中的字段）。当我同时发送超过200个请求时，在207我得到400 Bad Request响应，之后我可以等待一段时间但仍然从我的服务器获得相同的响应。看起来我的代码阻止了对网络资源的访问。当我重新启动服务器时，资源再次可用。 RestTemplate配置：

<bean id="restTemplate"                 class="org.springframework.web.client.RestTemplate">
    <constructor-arg ref="httpRequestFactory"> </constructor-arg>
</bean>

<bean id="httpRequestFactory"           class="org.springframework.http.client.HttpComponentsClientHttpRequestFactory">
    <constructor-arg ref="httpClient"> </constructor-arg>
    <property name="connectTimeout" value="1000" />
</bean>


<bean id="httpConnectionManager"        class="org.apache.http.impl.conn.PoolingClientConnectionManager">
     <property name="defaultMaxPerRoute" value="50" />
        <property name="maxTotal" value="100" />
</bean>


<bean id="httpClient" class="org.apache.http.impl.client.DefaultHttpClient" >
     <constructor-arg ref="httpConnectionManager" />
</bean>

请求：

ResponseEntity<String> response = restTemplate.exchange(
            "myaddress",
            HttpMethod.POST, request, String.class);

Answer 1

实际上我已经找到解决方案了。我想到在Accept标头中有许多条目“application / json”。我在代码中的错误是： restTemplate.getMessageConverters（）。添加（ new MappingJackson2HttpMessageConverter（））;

每次我使用单例restTemplate发送请求时执行

。

RestTemplate Bad请求许多请求
