Tomcat 网站配置和HTTP四种方法测试

一、tomcat的基本结构

1. conf/server.xml结构

<Server>
<Connector />
<Service>
<Engine>
<Realm></Realm>
<Host></Host>
</Engine>
</Service>
</Server>

<connector>用来定义开放的端口

<host> 用来定义网站

2. web.xml结构

<web-app>
<display-name></display-name>
<description></description>
<servlet></servlet>
<servlet></servlet>
</web-app>

网站的基本结构：

WEB-INF/classes----------存储servlet编译代码

WEB-INF/lib-----------------存储三方的库

WEB-INF/web.xml----------网站配置

根目录下---------------------- 存储jsp，html。

二、测试网站配置

阶段一：server.xml 配置

方法一：通过域名来测试

在<Engine>标签下添加主机

<Host name="域名" appBase="目录" unpackWARs="true" autoDeploy="true">

方法二：通过端口来测试

在Server下添加端口：

<Connector port="9000" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />

redirectPort表示如果是SSL链接，重定向到8443端口（SSL端口）

方法三：通过目录来测试

1.在webapps下建立目录 test

2.在Server.xml中的<Host>标签下添加

<Context path="/test" docBase="test" reloadable="true" />

appBase是绝对路径、也可以是相对路径（相对于Tomcat的安装目录）

阶段二：web.xml 配置

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1"
metadata-complete="true">

<display-name>Welcome to Tomcat</display-name>
<description>
Welcome to Tomcat
</description>
<servlet>
<servlet-name>default</servlet-name>
<servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>0</param-value>
</init-param>
<init-param>
<param-name>readonly</param-name>
<param-value>false</param-value>
</init-param>
<init-param>
<param-name>listings</param-name>
<param-value>false</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>

</web-app>

<init-param>

<param-name>readonly</param-name>

<param-value>false</param-value>

</init-param>

表示开放网站的PUT和DELETE方法。

三、测试程序配置
