    <a href="javascript:location.href='downFile?aname='+encodeURIComponent(' ${c.filName}');">${c.filName}</a>  

    JSP页面利用encodeURIComponent进行编码。传到action之后。在对其进行解码。代码如下:

    String filenames = URLDecoder.decode(URLDecoder.decode(ServletActionContext.getRequest().getParameter("aname"),"UTF-8")).trim();(SSH框架)

    后台代码(SSH框架注释):@Action(value = "/downFile", results = {
                @Result(name = SUCCESS , type="stream",location = "manageFile",params={"contentType","application/octet-stream",
                        "inputName","inputStream",
                        "contentDisposition","attachment;filenames=${filenames}",
                        "bufferSize","4096"}),
                @Result(name = ERROR, location = "/no.jsp") })
         public String downFile() throws UnsupportedEncodingException{
            System.out.println("测试进入下载action");
         String     filenames = URLDecoder.decode(URLDecoder.decode(ServletActionContext.getRequest().getParameter("aname"),"UTF-8")).trim();
         System.out.println("ceshi1"+filenames+"测试"); 
         File dir=new File(ServletActionContext.getServletContext().getRealPath("files")); 
          //判断文件是否上传,如果上传的话将会创建该目录 
          if(!dir.exists()){ 
           dir.mkdir(); //创建该目录 
          } 
          inputStream=ServletActionContext.getServletContext().getResourceAsStream("/files/"+filenames);
          if(inputStream!=null){
          System.out.println(inputStream);
          return SUCCESS;}
          else{
              return ERROR;
          }

    问题描述:

    1、将项目部署到服务器之后从页面接收的中文乱码

    2、数据库中原有的数据都能正常显示

    产生原因:没有对Tomcat服务器和MySQL进行配置更改

    解决流程:

    一、 修改Tomcat配置

    更改两个文件的配置

    1.server.xml

    URIEncoding="UTF-8" />

    2.web.xml

    setCharacterEncodingFilter

    org.apache.catalina.filters.SetCharacterEncodingFilter

    encoding

    UTF-8

    true

    默认tomcat7中上面这段代码在注释中,把它注释去掉。

    重启tomcat使配置生效。

    二、 mysql配置

    修改数据库的配置文件my.cnf文件,此文件如果通过rpm安装一般在/etc/目录下,具体修改成的样式如下图所示

    8631c071082a5f48763d5e7dfa5e88a1.png

    修改完成后,我们保存配置的修改,然后执行命令service mysqld restart。重新启动数据库。

    进入mysql,使用status查看数据库信息,执行命令show variables like 'character%'; 查看更改后的编码格式,执行 use 数据库名;然后执行show create database 数据库名; show create table 数据表名;查看对应的数据库和数据表编码

    28847f2f3b6b8ddd5f3c9ab90169c9fa.png

    修改此数据库的编码方式为utf8(默认是latin1)

    mysql> alter database 数据库名 character set utf8;

    SET NAMES 'utf8';

    微信小程序前端传到服务器后端中文乱码问题

    问题描述

    微信小程序通过wx.request接口连接服务器并传送data的json格式时,中文会出现乱码现象

    解决办法

    这里给出我研究出来的解决办法。先将你要传送的数据进行AES加密,在后台进行AES解密即可。虽然办法稍微有点复杂,但是对于处理乱码现象和增强数据的保密性安全性都有很大的帮助

    这里简单说一下AES加解密的步骤:
    1.前端运用到util.js和AES.js两个文件,其中在util.js里面运用AES.js文件设置有密钥和偏移iv
    2.在需要传输数据的demo.js中用util.js文件暴露出来的接口方法encrypt加密
    3.AESOperator.java是后端的工具类,在后端用其进行解密即可

    代码如下

    微信小程序前端代码

    demo.js

    var CryptoJS = require('../../util/util.js')
    
    var name = CryptoJS.Encrypt('xxx');
    wx.request({
          url: 'xxx',
          method: 'POST',
          dataType: 'STRING',
          data: {
    		name:name
          },
          header: {
            'content-type': 'application/json' // 默认值
          },
          success: function (res) {
            console.log(JSON.parse(res.data))
          },
        })
    

    demo.js主要用到了AES.js暴露的方法Encrypt,这里注意要先require AES.js 过来才能使用它暴露的方法

    Util.js

    var CryptoJS = require('AES.js');
    var key = CryptoJS.enc.Utf8.parse("1234123412ABCDEF");
    var iv = CryptoJS.enc.Utf8.parse('ABCDEF1234123412');
    // AES加密
    function Encrypt(word) {
      var srcs = CryptoJS.enc.Utf8.parse(word);
      var encrypted = CryptoJS.AES.encrypt(srcs, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 });
      encrypted =encrypted.ciphertext.toString().toUpperCase();
      return encrypted;
    }
    // AES解密
    function Decrypt(word) {
      var encryptedHexStr = CryptoJS.enc.Hex.parse(word);
      var srcs = CryptoJS.enc.Base64.stringify(encryptedHexStr);
      var decrypt = CryptoJS.AES.decrypt(srcs, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 });
      var decryptedStr = decrypt.toString(CryptoJS.enc.Utf8);
      return decryptedStr.toString();
    }
    module.exports = {
      Encrypt: Encrypt,
      Decrypt: Decrypt,
    }
    

    AES.js

    var CryptoJS = CryptoJS || function(u, p) {
      var d = {},
        l = d.lib = {},
        s = function() {},
        t = l.Base = {
          extend: function(a) {
            s.prototype = this;

            c.init.prototype = c;
            c.$super = this;
            return c
          },
          create: function() {
