根据项目的需要写了一个加密的标签，代码如下：
encrypt.tld
<?xml version="1.0" encoding="UTF-8"?><taglib xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee web-jsptaglibrary_2_0.xsd" version="2.0"> <tlib-version>1.0</tlib-version> <short-name>mytaglib</short-name> <uri>/encrypt-tags</uri> <tag> <name>encrypt</name> <tag-class>com.ctitc.analysis.util.Encrypt</tag-class> <attribute> <name>encryptValue</name> <required>true</required> <rtexprvalue>true</rtexprvalue> </attribute> <body-content>empty</body-content> </tag></taglib>
下面是java部分
Encrypt.java
package com.ctitc.analysis.util;import java.io.IOException;import javax.servlet.jsp.JspException;import javax.servlet.jsp.tagext.SimpleTagSupport;@SuppressWarnings("serial")public class Encrypt extends SimpleTagSupport { private String encryptValue; public void doTag() throws JspException { // TODO Auto-generated method stub try { encryptValue = java.net.URLEncoder.encode(encryptValue,"UTF-8"); getJspContext().getOut().write(encryptValue); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } public String getEncryptValue() { return encryptValue; } public void setEncryptValue(String encryptValue) { this.encryptValue = encryptValue; }}
下面是jsp部分

在js中标签无法将"<e:encrypt encryptValue='"+result +"'></e:encrypt>"
这种加密，因为里面有特殊字符。所有用result = encodeURI(result);来加密。
后台解析统一用java.net.URLDecoder.decode(result , "UTF-8");来解密。
这个可以解决传递中文参数乱码问题。
