标签：ack 连接池 ice 导入项目 前缀 建立 let 连接数 apache
前不久刚学过ssm框架的使用，在此记录下来，如果内容有误欢迎指正！
这篇文章只展示我建立项目的过程，至于各种配置这么写的原因在今后的时间里我会为Spring,Springmvc,mybatis各写一篇文章进行说明！
我使用的是eclipse，相信大多数新手都和我一样吧，新建web项目就不说了，各位应该都如喝水吃饭一样熟练了。
我是在eclipse中建立的maven项目，因此在pom.xml中写导入jar包的配置，maven自行下载jar包，目前只会这一种导入jar包的方式。
<dependencies>
<!-- Spring MVC -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>4.3.9.RELEASE</version>
</dependency>
<!-- Spring JDBC -->

</dependencies>
打开src/main/webapp/WEB-INF文件夹下的web.xml文件，在其中主要是配置DispatcherServlet,在其中添加如下配置：
<servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-*.xml</param-value> <!-- spring配置文件的路径，根据自己需要选择路径 --> </init-param> <load-on-startup>1</load-on-startup> <!-- 初始化优先级为1，使应用启动时就初始化DispatcherServlet --> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <url-pattern>*.yc</url-pattern> <!-- 需要DispatcherServlet拦截的请求的路径 --> </servlet-mapping>
我习惯将spring文件拆分为3个来写，分别是spring-mvc.xml,spring-service.xml,spring-dao.xml。
spring-mvc.xml

经过如上配置，这个应用的基本配置就完成了，然后就可以根据配置的位置去写你的代码了！

新人第一次写博客，回头一看写的很烂，但人都要有第一次嘛，以后会越来越好的，加油！！！
