springmvc基本配置

xml配置

1. 全局环境变量

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations">
        <list>
            <value>classpath:conf.properties</value>
        </list>
    </property>
</bean>

2. bean扫描

<context:component-scan base-package="cn.idea360" />

3. 引入其他xml配置文件

<import resource="classpath*:weixin/spring-mybatis.xml"/>

4. 读取配置文件

<context:property-placeholder location="classpath:conf.properties"/>

5. servlet配置

<servlet>
  <servlet-name>DispatcherServlet</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <init-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:application.xml</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
  <servlet-name>DispatcherServlet</servlet-name>
  <url-pattern>/</url-pattern>
</servlet-mapping>

6. 编码配置

<filter>
  <filter-name>CharacterEncodingFilter</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>
  <init-param>
    <param-name>forceEncoding</param-name>
    <param-value>true</param-value>
  </init-param>
</filter>
<filter-mapping>
  <filter-name>CharacterEncodingFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

7. 注解

<mvc:annotation-driven/>
<context:annotation-config />
