首先POST與GET請求的應用場景:

除了form表單提交和ajax指定post請求可以使post,其他都是get請求,比如瀏覽器直接寫URL或者A標籤

POST請求:

配置編碼過濾器:解決post請求中文亂碼

  <filter>
    <filter-name>characterEncoding</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>
  </filter>

  <filter-mapping>
    <filter-name>characterEncoding</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping
 
>

GET請求:

修改tomcat下server.xml 的埠設定中加URIEncoding=”UTF-8”
