springmvc参数传递的几种乱码情况

Answer 1

@RequestParam 或者@PathVariable 等从URL或者Form Data 获取参数数据。

当其中有中文的时候，会发生了乱码。
1.方法一：修改Tomcat的server.xml
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />

添加URIEncoding="utf-8"

<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" URIEncoding="utf-8"/>
2.方法二：手动更改
String name = new String(name.getBytes("ISO-8859-1"),"UTF-8");

其次POST方法

方法一：使用Spring的字符过滤器
配置在web.xml中：
<filter>
<filter-name>encoding</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>encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
方法二：手动更改
