本文介绍如何使用Spring的RestTemplate组件来上传文件，并详细展示了设置MediaType.APPLICATION_OCTET_STREAM及配置RestTemplate的相关代码实例。

			HttpHeaders headers = new HttpHeaders();
			headers.setContentType(MediaType.APPLICATION_OCTET_STREAM);

			HttpEntity<byte[]> httpEntity = new HttpEntity<(FileTools.toByteArray(file), headers);
			HttpEntity<String> response = restTemplate.exchange(url, HttpMethod.PUT, httpEntity, String.class);

一定要为resttemplate配置上APPLICATION_OCTET_STREAM对应的转换器

    <bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
	     <property name="requestFactory">
	        <bean class="org.springframework.http.client.HttpComponentsClientHttpRequestFactory" >
	            <constructor-arg ref="httpClient"/>
	            <!--连接时间(毫秒)-->
	            <property name="connectTimeout" value="${http.connect.timeout}"/>
	            <!--读取时间(毫秒)-->
	            <property name="readTimeout" value="${http.read.timeout}"/>
	        </bean>
	    </property>
        <property name="errorHandler">
            <bean class="org.springframework.web.client.DefaultResponseErrorHandler"/>

                        </list>
                    </property>
                </bean>
