Spring 字符编码过滤

在项目下的web.xml文件中配置字符编码过滤

<!-- 配置编码过滤器，保存中文的时候用到 --><filter><filter-name>encodingFilter</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><filter-mapping><filter-name>encodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping>

如上，是对所有的请求进行编码过滤，编码格式为UTF-8。
