java乱码

解决乱码的方式：
1. new String("".getBytes("iso-8859-1","utf-8");
2. <form> 表单的提交方式
3. 在服务器中修改编码方式：
<Service name="Tomcat_1">
<Connector port="80" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="gbk"/>
<Engine name="Tomcat_1" defaultHost="localhost">
<Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false">
<Context path="" docBase="F:\2013_ems\WebRoot" debug="0" reloadable="true" />
</Host>
</Engine>
</Service>
