HttpClient相关参数的设置方法
为了方便HttpClient相关参数的配置增加了接口ApacheHttpClientBuilder并实现了一个默认配置DefaultApacheHttpClientBuilder.在默认配置中具体的配置参数如下:
private int connectionRequestTimeout = 3000;//从连接池获取链接的超时时间设置,默认3000ms private int connectionTimeout = 5000;//建立链接的超时时间,默认5000ms.(由于使用了连接池,这个参数没有实际意义) private int soTimeout = 5000;//连接池socket超时时间,默认5000ms private int idleConnTimeout = 60000;//空闲链接的超时时间,默认60000ms private int checkWaitTime = 60000;//空闲链接的检测周期,默认60000ms private int maxConnPerHost = 10;//每路最大连接数,默认10 private int maxTotalConn = 50;//连接池最大连接数,默认50 private String userAgent;//HttpClient请求时使用的User Agent(默认为HttpClient的默认值)参考MP_Quick Start或者CP_Quick-Start在API初始化是我们需要设置Wx**ConfigStorage,可以通过方法#setApacheHttpClientBuilder设置ApacheHttpClientBuilder的实现类来配置具体的HttpClient的参数配置.默认没有设置本参数的时候将会使用DefaultApacheHttpClientBuilder中默认的参数配置.下面以DefaultApacheHttpClientBuilder为例给出修改参数的配置方法
Wx**InMemoryConfigStorage config = new Wx**InMemoryConfigStorage(); config.setHttpProxyHost(..);//设置代理地址,没有可以无需设置 config.setHttpProxyPort(..);//设置代理端口,没有可以无需设置 config.setHttpProxyUsername(..);//设置代理用户名,没有可以无需设置 config.setHttpProxyPassword(..);//设置代理密码,没有可以无需设置 DefaultApacheHttpClientBuilder clientBuilder = DefaultApacheHttpClientBuilder.get(); clientBuilder.setConnectionRequestTimeout(..)//从连接池获取链接的超时时间(单位ms) clientBuilder.setConnectionTimeout(..)//建立链接的超时时间(单位ms) clientBuilder.setSoTimeout(..)//连接池socket超时时间(单位ms) clientBuilder.setIdleConnTimeout(..)//空闲链接的超时时间(单位ms) clientBuilder.setCheckWaitTime(..)//空闲链接的检测周期(单位ms) clientBuilder.setMaxConnPerHost(..)//每路最大连接数 clientBuilder.setMaxTotalConn(..)//连接池最大连接数 clientBuilder.setUserAgent(..)//HttpClient请求时使用的User Agent config.setApacheHttpClientBuilder(clientBuilder); //设置自定义的ApacheHttpClientBuilder对于微信支付，可以通过设置 WxPayConfig 中的 apiV3HttpClientBuilderCustomizer 属性，实现 HttpClientBuilderCustomizer 来进行配置，具体配置方法参考 Apache HttpClient 组件中 HttpClientBuilder 的配置：
payConfig.setApiV3HttpClientBuilderCustomizer(clientBuilder -> { clientBuilder.setMaxConnTotal(300); clientBuilder.setMaxConnPerRoute(250); clientBuilder.setConnectionTimeToLive(45, TimeUnit.SECONDS); }); wxPayService.setConfig(payConfig);方法一,可以自己实现ApacheHttpClientBuilder接口然后在Wx**ConfigStorage中设置.推荐此方法
方法二,使用DefaultApacheHttpClientBuilder,考虑到DefaultApacheHttpClientBuilder并不是最优解,所以没有提供public的构造方法,只提供了一个静态方法获取实例.如果一定要使用这个类来实现自定义配置的话我们需要定义一个Spring的FactoryBean,下面给出参考代码.
import org.springframework.beans.factory.FactoryBean; import me.chanjar.weixin.common.util.http.ApacheHttpClientBuilder; import me.chanjar.weixin.common.util.http.DefaultApacheHttpClientBuilder; public class DefaultApacheHttpClientBuilderFactoryBean implements FactoryBean<ApacheHttpClientBuilder> { private int connectionRequestTimeout; private int connectionTimeout; private int soTimeout; private int idleConnTimeout; private int checkWaitTime; private int maxConnPerHost; private int maxTotalConn; private String userAgent; public ApacheHttpClientBuilder getObject() throws Exception { DefaultApacheHttpClientBuilder clientBuilder = DefaultApacheHttpClientBuilder.get(); clientBuilder.setConnectionRequestTimeout(this.connectionRequestTimeout); clientBuilder.setConnectionTimeout(this.connectionTimeout); clientBuilder.setSoTimeout(this.soTimeout); clientBuilder.setIdleConnTimeout(this.idleConnTimeout); clientBuilder.setCheckWaitTime(this.checkWaitTime); clientBuilder.setMaxConnPerHost(this.maxConnPerHost); clientBuilder.setMaxTotalConn(this.maxTotalConn); clientBuilder.setUserAgent(this.userAgent); return clientBuilder; } public Class<?> getObjectType(){ return ApacheHttpClientBuilder.class; } public boolean isSingleton(){ return true; } public void setConnectionRequestTimeout(int connectionRequestTimeout) { this.connectionRequestTimeout = connectionRequestTimeout; } public void setConnectionTimeout(int connectionTimeout) { this.connectionTimeout = connectionTimeout; } public void setSoTimeout(int soTimeout) { this.soTimeout = soTimeout; } public void setIdleConnTimeout(int idleConnTimeout) { this.idleConnTimeout = idleConnTimeout; } public void setCheckWaitTime(int checkWaitTime) { this.checkWaitTime = checkWaitTime; } public void setMaxConnPerHost(int maxConnPerHost) { this.maxConnPerHost = maxConnPerHost; } public void setMaxTotalConn(int maxTotalConn) { this.maxTotalConn = maxTotalConn; } public void setUserAgent(String userAgent) { this.userAgent = userAgent; } }
