了解dlog4j系统的概况。搭配环境运行该系统。

一、Struts 与 Velocity 的集成

把 Velocity JAR 放在类路径中。
修改 web.xml 文件让它识别 Velocity servlet。
把 Velocity toolbox.xml 放在应用程序的 WEB-INF 目录下。
修改 struts-config，把它的视图指向 Velocity 模板而不是 JSP。
为每个需要显示的页面创建 Velocity 模板。

第 1 步：把 Velocity JAR 放在 WEB-INF/lib 下

将需要的JAR放在 WEB-INF\lib 下面即可。

第 2 步：修改 web.xml，识别 Velocity 的 servlet

修改 Struts 的 web.xml 文件，让它识别 Velocity 的 servlet 并把所有以 .vm 结尾的资源请求定向到 DLOG_VelocityServlet，如清单 1 所示。

1. 修改 web.xml，声明 Velocity servlet

<servlet>
2

<servlet-name>DLOG_VelocityServlet</servlet-name>【1】
3

<servlet-class>com.liusoft.dlog4j.servlet.DLOG_VelocityServlet</servlet-class>【2】
4

<init-param>
5

<param-name>org.apache.velocity.toolbox</param-name>
6

<param-value>/WEB-INF/conf/velocity-toolbox.xml</param-value>
7

</init-param>【3】
8

<init-param>
9

<param-name>org.apache.velocity.properties</param-name>
10

<param-value>/WEB-INF/conf/velocity.properties</param-value>
11

</init-param>【4】
12

<init-param>
13

<param-name>encoding</param-name>
14

<param-value>UTF-8</param-value>
15

</init-param>
16

<load-on-startup>4</load-on-startup>【5】
17

</servlet>
18

<servlet-mapping>
19

<servlet-name>DLOG_VelocityServlet</servlet-name>
20

<url-pattern>*.vm</url-pattern>
21

</servlet-mapping>【6】

（1）声明了 Velocity servlet 并给了它一个 velocity 句柄。
（2）声明了 Velocity servlet 的类名。 Velocity servlet 接受“toolbox”参数。toolbox 是声明应用程序的可用工具的位置。
（3）告诉 VelocityServlet 在哪里可以找到 toolbox 的配置。
（4）告诉 VelocityServlet 在哪里可以找到 velocity.properties的配置。
（5）设置了 load-on-startup 标记，确保在正确的时间装入 Velocity servlet。任何大于或等于 0 的值都会迫使容器通过调用 servlet 的 init() 方法来装入它。放在 load-on-startup 标记体中的值决定了不同的 servlet 的 init 方法调用的次序。例如，0 在 1 之前调用，而 1 在 2 之前调用。缺少的标记或负值允许 servlet 容器根据自己的选择装入 servlet。
（5）声明了 servlet 映射，强迫所有用 .vm 结尾的资源请求定向到 Velocity servlet。

注意（5）中的<servlet-name> 必须与（1）中的<servlet-name> 匹配。交错的声明和映射会在日志中生成错误。

第 3 步：把 toolbox.xml 放在 WEB-INF 下
dlog4j系统在WEB-INF\conf\velocity-toolbox.xml是dlog4j自己构建的工具。如下：

<?xml version="1.0" encoding="UTF-8"?>
