2018-10-07 springmvc配置

一 pom.xml引入依赖包
<dependency>

        <groupId>javax.servlet</groupId>

        <artifactId>javax.servlet-api</artifactId>

        <version>3.1.0</version>

        <scope>provided</scope>

      </dependency>

      <dependency>

        <groupId>org.springframework</groupId>

        <artifactId>spring-webmvc</artifactId>

        <version>5.0.5.RELEASE</version>

      </dependency>   

二  web.xml配置控制器,编码过滤器

<servlet>

       <servlet-name>dispatcher</servlet-name>

       <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

  <!--容器启动加载  -->

      <init-param>

            <param-name>contextConfigLocation</param-name>

            <param-value>classpath:applicationContext-mvc.xml</param-value>

        </init-param>

        <load-on-startup>1</load-on-startup>

        <async-supported>true</async-supported>

  </servlet>

  <servlet-mapping>

       <servlet-name>dispatcher</servlet-name>

       <url-pattern>/</url-pattern> 

  </servlet-mapping>

<!-- Character Encoding filter 解决中文问题 -->

    <filter> 

        <filter-name>encodingFilter</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>encodingFilter</filter-name>

        <url-pattern>/*</url-pattern>

    </filter-mapping>

三 在applicationContext-mvc.xml配置注解驱动,自动扫描包,视图解析器

<!-- 添加自动扫描包 -->

    <context:component-scan base-package="com.ggy.controller"></context:component-scan>

也可以这样写

<context:component-scan base-package="com.wangzhixuan">

        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>

        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/>

        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Repository"/>

    </context:component-scan>

<!--视图解析器  -->

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <property name="prefix" value="/WEB-INF/views/"></property>

        <property name="suffix" value=".jsp"></property>

</bean>

  <!--可简写  <mvc:annotation-driven/>添加注解驱动-->

<mvc:annotation-driven>

        <mvc:message-converters register-defaults="true">

            <!-- 将StringHttpMessageConverter的默认编码设为UTF-8 -->

            <bean class="org.springframework.http.converter.StringHttpMessageConverter">

                <constructor-arg value="UTF-8"/>

            </bean>

        </mvc:message-converters>

    </mvc:annotation-driven>

配置静态资源访问

<!--允许springmvc访问静态资源 -->

<mvc:default-servlet-handler/>
