idea web项目乱码解决

首先修改web.xml配置文件

<!-- 字符过滤器 -->  
  <filter>  
    <filter-name>encodingFilter</filter-name>  
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>  
    <init-param><!-- 针对request -->
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
    <init-param><!-- 针对response --> 
        <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>

如果是通过ajax传值：

在你的spring-*.xml文件中配置如下属性：

<bean id="stringHttpMessageConverter" class="org.springframework.http.converter.StringHttpMessageConverter">  
     		<property name="defaultCharset" value="UTF-8"/>  
 </bean>

1，找到tomcat路径下的 D:\Appache\apache-tomcat-8.0.47\conf\server.xml，加上URIEncoding="utf-8"
