Question

我正在尝试Spring注入org.apache.http.impl.conn.PoolingHttpClientConnectionManager和org.apache.http.config.SocketConfig。我试图设置默认的连接数，最大连接数和soTimeout值。我们使用的是apache版本4.1,1。

在spring初始化时，我收到一个错误，指示soTimeout和tcpNoDelay不是可写属性。从我的所有Google搜索中，我发现这些属性应该是可写的。有人可以帮我理解Apache 4.3.1上的HTTP客户端初始化

的applicationContext.xml

<bean id="dispatcherHttpConnectionManager" class="org.apache.http.impl.conn.PoolingHttpClientConnectionManager">
<!-- property name="params" ref="dispatcherHttpConnectionParams" /-->
<property name="maxTotal" value="1000" />
<property name="defaultMaxPerRoute" value="50" />
<property name="defaultSocketConfig" ref="apacheSocketConfig" />

错误：

身份验证/授权失败，错误为org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dispatcherHttpConnectionManager' defined in class path resource [dispatchClientApplicationContext.xml]: Cannot resolve reference to bean 'apacheSocketConfig' while setting bean property 'defaultSocketConfig'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'apacheSocketConfig' defined in class path resource [dispatchClientApplicationContext.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'soTimeout' of bean class [org.apache.http.config.SocketConfig$Builder]: Bean property 'soTimeout' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

老问题我知道，但是......

您需要使用SocketConfig.Builder（http://javadox.com/org.apache.httpcomponents/httpcore/4.3/org/apache/http/config/SocketConfig.Builder.html）来构造SocketConfig bean：

<bean id="socketConfigBuilder" class="org.apache.http.config.SocketConfig" factory-method="custom">
    <property name="soTimeout" value="1000" /> 
</bean>

<bean id="connectionManager" class="org.apache.http.impl.conn.PoolingHttpClientConnectionManager">
    <property name="defaultSocketConfig"><bean factory-bean="socketConfigBuilder" factory-method="build" /></property>
</bean>

用于版本4.3.1的Apache HTTP客户端Spring应用程序上下文XML
