概述
</ul>　　乱码问题是大家在日常开发过程中经常会遇到的问题，由于各自环境的不同，解决起来也费时费力，本文主要介绍一般性乱码问题的解决方法与步骤，开发工具采用Eclipse+Tomcat，统一设置项目编码UTF-8为例，供大家参考。

解决方法与步骤

　　步骤一：首先，检查JSP页面声明的编码是否正确，正确示例（注意标红的地方）：

<%@ page language="java" contentType="text/html; charset=UTF-8"
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8" />pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8" /><meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8" /> <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8" /><title>Insert title here</title>
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8" /></head>
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8" /><body>
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8" />
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8" /></body>
</html>

复制代码

　　步骤二：在确认步骤一没有问题后，接下来检查项目属性编码、 JSP 页面属性的编码和 Java 文件的属性编码，项目属性编码和文件属性编码也需要统一设置为 UTF-8 ，正确效果如下图：

　　为了方便起见，可以对需要统一编码的文件格式进行编码关联设置，如下图：

　　步骤三：在确认步骤二没有问题后，接下来就需要检查 Tomcat 的编码，需要把 Tomcat 的编码也设置为 UTF-8，找到 Tomcat 安装目录下的 conf 目录下的 server.xml 文件，如果没有修改过 Tomcat 的端口，则直接搜索8080 ，找到对应的 Connector 标签加上 URIEncoding 属性，值为 UTF-8。

<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8" />

　　使用 Eclipse 做为开发工具，还需修改 Eclipse 中项目对应的 Tomcat 的配置文件，方法同上。

　　至此，常用的解决项目中文乱码的“三码合一”的配置方法都已经配置好了，为了彻底的解决乱码问题，我们还可以通过在 web.xml 中配置 Spring 的编码过滤器来处理乱码问题。
