技術標籤：SpringMVC過濾器javaweb.xmlspring

下面展示一些 內聯程式碼片。

在Web.xml中配置如下:

// An highlighted block
<!-- 配置springMVC編碼過濾器 -->
  <filter>
  	<filter-name>CharacterEncodingFilter</filter-name>
  	<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class
 
>
  	<!-- 設定過濾器中的屬性值 -->
  	<init-param>
  		<param-name>encoding</param-name>
  		<param-value>UTF-8</param-value>
  	</init-param>
  	<!-- 啟動過濾器 -->
  	<init-param>
  		<param-name>forceEncoding</param-name>
  		<param-value>true
 
</param-value>
  	</init-param>
  </filter>
  <!-- 過濾所有請求 -->
  <filter-mapping>
  	<filter-name>CharacterEncodingFilter</filter-name>
  	<url-pattern> / * </url-pattern>
  </filter-mapping>
在web.xml配置過濾器以後會將所有請求過濾，但是實際開發中有些靜態資源
不需要過濾，於是便要在springMVC-
 
servlet.xml配置檔案下配置靜態資源不過濾
springMVC-servlet.xml檔案中配置：
<!-- location表示路徑，mapping表示檔案，**表示該目錄下的檔案以及子目錄的檔案 -->
       <mvc:resources location="/css/" mapping="/css/**"/>
       <mvc:resources location="/images/" mapping="/images/**"/>
       <mvc:resources location="/scripts/" mapping="/scripts/**"/>
var foo = 'bar';

Jackson亂碼問題解決:
1.//produces:指定響應體返回型別和編碼
@RequestMapping(value = "/json1",produces = "application/json;charset=utf-8")
2.<mvc:annotation-driven>
   <mvc:message-converters register-defaults="true">
       <bean class="org.springframework.http.converter.StringHttpMessageConverter">
           <constructor-arg value="UTF-8"/>
       </bean>
       <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
           <property name="objectMapper">
               <bean class="org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean">
                   <property name="failOnEmptyBeans" value="false"/>
               </bean>
           </property>
       </bean>
   </mvc:message-converters>
</mvc:annotation-driven>
