依赖jar包配置
SpringMVC与Spring整合
SpringMVC + Spring整合:
- 拷贝JAR包.
- 修改web.xml文件.
a.配置SpringMVC的核心控制器.
b.配置Web应用启动时自动创建spring容器.
- 增加SpringMVC的配置文件.
- 增加Spring的配置文件,如果配置文件名不是默认的,还需要在web.xml文件指定Spring文件的路径.
----------------------经过上面几步，整合成功-----------------------
接下来的开发很简单:
Controller开发(但Controller不要主动new Service组件,只要有setter)、配置，与不整合Spring基本一样.
Service组件配置在Spring容器中.
注意：Controller中需要依赖的Service对象要与Service类的配置ID必须相同.
修改web.xml文件
<!-- 配置工程的编码过滤器（spring提供） -->
<filter>
<filter-name>charsetEncoding</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>charsetEncoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
