关于4-9节测试shopadmin/shopoperation乱码问题

Question

看起来好像是浏览器问题，在mac的safari和chrome中不可以显示中文，手机的chrome也不行，而在手机自带的浏览器却可以正常显示，为何？

同学好，在eclipse里面右键所有文件，看看属性里面的编码是否utf-8，然后看看数据库是否utf8，因为乱码肯定就是前后端编码不一致导致的。

pom.xml 注意utf8的设置

  老师，你好。我找到了解决方法。由于页面放在webapp根目录下不出现乱码，但是当它放在./webapp/WEB-INF下却出现乱码。从请求访问到资源传送到浏览器涉及多次io操作是引起页面乱码的原因。那么我是在工程的web.xml目录下插入了filter，强制转换，代码如下：
  <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>

  上面忘了mapping了，还要在上面的代码下加上
  <filter-mapping>
  		<filter-name>characterEncodingFilter</filter-name>
  		<url-pattern>/*</url-pattern>
  	</filter-mapping>
