表單提交controller獲得中文引數後亂碼解決方案

注意： jsp頁面編碼設定為UTF-8

form表單提交方式為必須為post，get方式下面spring編碼過濾器不起效果

1. <%@ page language="java"import="java.util.*"pageEncoding="UTF-8"%>

1. <formaction="${ctx}/user/addUser"name="userForm"method="post">

修改web.xml，增加編碼過濾器，如下（注意，需要設定forceEncoding引數值為true）

1. <
   filter>
2.         <filter-name>characterEncodingFilter</filter-name>
3.         <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
4.         <init-param>
5.             <param-name>encoding</param-name>
6.             <param-value>UTF-8
   </param-value>
7.         </init-param>
8.         <init-param>
9.             <param-name>forceEncoding</param-name>
10.             <param-value>true</param-value>
11.         </init-param>
12.     </filter>
13.     <filter-mapping>
14.         <filter-name>characterEncodingFilter
    </filter-name>
15.         <url-pattern>/*</url-pattern>
16.     </filter-mapping>

資料庫編碼是否支援中文

資料庫表和表字段是否正確

在配置連線資料庫的引數設定修改：

1. <propertyname="url"value="jdbc:mysql://localhost:3306/dbname?useUnicode=true&characterEncoding=UTF-8"></property>
