两步实现基于Servlet的反向代理

1.准备依赖包4个（项目中存在则可忽略）如下：

+- org.apache.httpcomponents:httpclient:jar:4.5.2:compile

+- org.apache.httpcomponents:httpcore:jar:4.4.4:compile

| +- commons-logging:commons-logging:jar:1.2:compile

| \- commons-codec:commons-codec:jar:1.9:compile

2.web.xml配置文件添加servlet配置

<servlet-name>poxyHttpRequest</servlet-name>

<servlet-class>org.mitre.dsmiley.httpproxy.ProxyServlet</servlet-class>

<init-param>

<param-name>targetUri</param-name>

<param-value>https://www.baidu.com/s</param-value>

</init-param>

<init-param>

<param-name>log</param-name>

<param-value>true</param-value>

</init-param>

</servlet>

<servlet-mapping>

<servlet-name>poxyHttpRequest</servlet-name>

<url-pattern>/s/*</url-pattern>

</servlet-mapping>

代理多个uri ，配置多个servlet 即可

3.重启项目，验证

两步实现基于Servlet的反向代理

功能正常，至此完毕！
