前后端数据交互乱码

前后端数据交互乱码

独立修改编码方式

String name = new String((request.getParameter("name")).getBytes("iso-8859-1"),"utf-8");

try {
request.setCharacterEncoding("utf-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}

在web.xml中设置编码过滤器，一劳永逸

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