配置一道拦截器即可解决乱码
配置方式如下：
在web.xml中：
<!--过滤器处理乱码-->
<filter>
<filter-name>CharacterEncoding</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<!--请求-->
<init-param>
<param-name>encoding</param-name>
<param-value>utf-</param-value>
</init-param>
<!--响应-->
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter> <filter-mapping>
<filter-name>CharacterEncoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
