Tomcat7下项目切换到Tomcat8后,出现乱码。html
不管Google仍是百度,多数解决方法是server.xml设置URIEncoding="UTF-8"。apache
对于Tomcat7下遇到乱码问题,这样配置是正确的;可是对”Tomcat7正常,切换到Tomcat8”乱码的状况无效。tomcat
Tomcat8的server.xml配置Connector节点添加属性URIEncoding="ISO-8859-1"。less
参考:官方迁移说明编码
https://tomcat.apache.org/tomcat-7.0-doc/config/http.html.net
URIEncoding This specifies the character encoding used to decode the URI bytes, after %xx decoding the URL. If not specified, ISO-8859-1 will be used.code
https://tomcat.apache.org/tomcat-8.0-doc/config/http.htmlserver
URIEncoding This specifies the character encoding used to decode the URI bytes, after %xx decoding the URL. If not specified, UTF-8 will be used unless the org.apache.catalina.STRICT_SERVLET_COMPLIANCE system property is set to true in which case ISO-8859-1 will be used.xml
Tomcat7对URI默认编码是ISO-8859-1htm
Tomcat8对URI默认编码是UTF-8
new String(value.getBytes("ISO-8859-1"), param);
若是server.xml配置上URIEncoding="UTF-8"就不须要了。 进而项目直接迁移到Tomcat8,不修改server.xml,或者再次加上URIEncoding="UTF-8"也是不会有问题。
对于在Tomcat8开发项目,就简单不少,不须要上面的那段不人道的代码。可是从Tomcat7迁移上来的项目,要么,去掉上面的代码,要么server.xml添加URIEncoding="ISO-8859-1",浪费Tomcat8一番美意。
