Tomcat URL乱码

我们在开发REST服务的时候，尤其是做中文项目的时候，会遇到传入参数乱码的问题，这个就比较麻烦了，因为原因真的很复杂，根本不止我所列的两个地方，还得具体问题具体分析了。

如果你用的是Spring MVC，首先要检查一下CharacterEncodingFilter是否配置了编码

<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>

然后再看一下Tomcat的server.xml是否配置了编码

http://tomcat.apache.org/tomcat-6.0-doc/config/ajp.html#Common_Attributes

<!-- A "Connector" represents an endpoint by which requests are received
and responses are returned. Documentation at :
Java HTTP Connector: /docs/config/http.html (blocking & non-blocking)
Java AJP  Connector: /docs/config/ajp.html
APR (HTTP/AJP) Connector: /docs/apr.html
Define a non-SSL HTTP/1.1 Connector on port 8080
-->
<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443" URIEncoding="UTF-8"/>

然后就好用了哦～
