【JAVAEE基础学习（12）】--springMVC常用配置篇

一、常用配置文件头信息：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/mvc
        https://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx.xsd">
</beans>

二、解决springmvc中的乱码

  <filter>
    <filter-name>encoding</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>encoding</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

三、springmvc中的时间类型转换器设置

    <mvc:annotation-driven conversion-service="conversionService"/>
    
xml格式--------------
    <bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
        <property name="formatters">
            <set>
                <bean class="org.springframework.format.datetime.DateFormatter">
                    <property name="pattern" value="yyyy-MM-dd"/>
                </bean>
            </set>
        </property>
    </bean>

注解格式----------------------
@DateTimeFormat(pattern="yyyy-MM-dd") 

四、配置视图解析器

    <!-- 视图解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
          id="internalResourceViewResolver">
        <!-- 前缀 -->
        <property name="prefix" value="/WEB-INF/jsp/" />
<!--        <property name="prefix" value="/Hello/" />-->
        <!-- 后缀 -->
        <property name="suffix" value=".jsp" />

    </bean>

 五、使用隐藏域表单方式提交restfull风格请求

  <input type="hidden" name="_method" value="">

  <filter>
    <filter-name>hiddenHttpMethodFilter</filter-name>
    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>hiddenHttpMethodFilter</filter-name>
    <servlet-name>DispatcherServlet</servlet-name>
  </filter-mapping>

六、自定义前后端json数据交互格式

<mvc:message-converters register-defaults="true">
    <bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
        <property name="supportedMediaTypes" value="application/json"/>
        <property name="features">
            <list>
                <value>WriteMapNullValue</value>
                <value>WriteDateUseDateFormat</value>
            </list>
        </property>
    </bean>
</mvc:message-converters>

七：常用web.xml头文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
         http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">

八：配置文件上传插件

<bean id="multipartResolver" 
    class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <property name="maxUploadSize" value="104857600" />
        <property name="maxInMemorySize" value="4096" />
        <property name="defaultEncoding" value="UTF-8"/>
</bean>

不喜勿喷，感谢理解
