项目基础配置 37 | 38 | 创建git仓库，本地配置idea并测试pull和push。 39 | 40 | 创建SpringBoot工程，导入Web，Velocity和Aop的包。 41 | 42 | 生成Maven项目，pom.xml包含上述依赖，应用名称是toutiao,小组id是com.nowcoder。 43 | 44 | ## 基本框架开发 45 | 46 | 创建基本的controller，service和model层。 47 | 48 | controller中使用注解配置，requestmapping，responsebody基本可以解决请求转发以及响应内容的渲染。responsebody自动选择viewresolver进行解析。 49 | 50 | 使用pathvariable和requestparam传递参数。 51 | 52 | 使用velocity编写页面模板，注意其中的语法使用。常用$!{}和${} 53 | 54 | 使用http规范下的httpservletrequest和httpservletresponse来封装请求和相响应，使用封装好的session和cookie对象。 55 | 56 | 使用重定向的redirectview和统一异常处理器exceptionhandler 57 | 58 | AOP和IOC 59 | 60 | IOC解决对象实例化以及依赖传递问题，解耦。 61 | 62 | AOP解决纵向切面问题，主要实现日志和权限控制功能。 63 | 64 | aspect实现切面，并且使用logger来记录日志，用该切面的切面方法来监听controller。 65 | 66 | ## 数据库配置和首页的创建 67 | 68 | 使用mysql创建数据库和表，建议自己写一下sql到mysql命令行跑一下。 69 | 70 | 加入mybatis和mysql的maven仓库，注意，由于现在版本的springboot不再支持velocity进而导致我使用较早版本的springboot，所以这里提供一可以正常运行的版本设置。 71 | 72 | springboot使用1.4.0 73 | 74 | mybatis-spring-boot-starter使用1.2.1 75 | 76 | mysql-connector-java使用5.1.6 77 | 78 | 亲测可用。 79 | 80 | 接下来写controller，dao和service。注意mybatis的注解语法以及xml的配置要求，xml要求放在resource中并且与dao接口在相同的包路径下。 81 | 82 | application.properties增加spring配置数据库链接地址 83 | 84 | 两个小工具： 85 | ViewObject:方便传递任何数据到 86 | VelocityDateTool:velocity自带工具类 87 | 88 | 写好静态文件html css和js。并且注意需要配置 89 | spring.velocity.suffix=.html 保证跳转请求转发到html上 90 | spring.velocity.toolbox-config-location=toolbox.xml 91 | 92 | 至此主页基本完成，具体业务逻辑请参考代码。 93 | 94 | ## 用户注册登录以及使用token 95 | 96 | 完成用户注册和登录的controller,service和dao层代码 97 | 98 | 新建数据表login_ticket用来存储ticket字段。该字段在用户登录成功时被生成并存入数据库，并被设置为cookie， 99 | 下次用户登录时会带上这个ticket，ticket是随机的uuid，有过期时间以及有效状态。 100 | 101 | 使用拦截器interceptor来拦截所有用户请求，判断请求中是否有有有效的ticket，如果有的话则将用户信息写入Threadlocal。 102 | 所有线程的threadlocal都被存在一个叫做hostholder的实例中，根据该实例就可以在全局任意位置获取用户的信息。 103 | 104 | 该ticket的功能类似session，也是通过cookie写回浏览器，浏览器请求时再通过cookie传递，区别是该字段是存在数据库中的，并且可以用于移动端。 105 | 106 | 通过用户访问权限拦截器来拦截用户的越界访问，比如用户没有管理员权限就不能访问管理员页面。 107 | 108 | 配置了用户的webconfiguration来设置启动时的配置，这里可以将上述的两个拦截器加到启动项里。 109 | 110 | 配置了json工具类以及md5工具类，并且使用Java自带的盐生成api将用户密码加密为密文。保证密码安全。 111 | 112 | 数据安全性的保障手段：https使用公钥加密私钥解密，比如支付宝的密码加密，单点登录验证，验证码机制等。 113 | 114 | ajax异步加载数据 json数据传输等。 115 | 116 | 117 | ## 上传图片至云存储，以及新增一条分享内容 118 | 119 | 图片的本地上传，前端请求发送二进制图片文件流，content-type是multipart类型 120 | 121 | 后端Spring也是用multipartFile来接收该对象 122 | 123 | 接收对象后验证文件的格式和后缀是否正确，将文件名统一用uuid来命名，并加上后缀名，这样可以避免文件名重复。 124 | 125 | 可以直接使用IOStreamUitl的copy方法将文件直接拷贝到本地，返回一个本地访问路径即可。 126 | 127 | 但是本地存储大量图片显然不合适，所以可以使用七牛云或者阿里云提供的对象存储服务来存储图片。 128 | 129 | 这里使用阿里云的OSS，首先建立一个bucket，并且获取地址，key和password等信息，添加maven依赖， 130 | 直接使用一个简单的文件上传例子就可以实现上传功能，并且返回一个指向该图片存储地址的url。 131 | 132 | 新增一个分享内容的步骤：选择上传图片，调用图片上传接口并返回url，然后输入内容，将这些数据一并保存到数据库。 133 | 134 | 本次开发中使用到了fiddler工具来实现浏览器的代理，该工具可以先拦截这个请求，再进行转发，所以在工具内可以解析请求和响应内容。 135 | 136 | 通过这个工具可以很清晰地看到http请求的实现细节。通过换行符区分字段，并且在字段长度超过首部长度后，后面的contentlength长度就是请求体的内容了，里面即可以放json，也可以直接放二进制字节流，如图片。其中post方法才带有请求体，get方法是没有请求体的。 137 | 138 | ## 新增评论和站内信功能 139 | 140 | 首先建立表comment和message分别代表评论和站内信。 141 | 142 | 依次开发model，dao，service和controller。 143 | 144 | 评论的逻辑是每一条资讯下面都有评论，显示评论数量，具体内容，评论人等信息。 145 | 146 | 消息的逻辑是，两个用户之间发送一条消息，有一个唯一的会话id，这个会话里可以有多条这两个用户的交互信息。 147 | 通过一个用户id获取该用户的会话列表，再根据会话id再获取具体的会话内的多条消息。 148 | 149 | 逻辑清楚之后，再加上一些附加功能，比如显示未读消息数量，根据时间顺序排列会话和消息。 150 | 151 | 本节内容基本就是业务逻辑的开发，没有新增什么技术点，主要是前后端交互的逻辑比较复杂，前端的开发量也比较大。 152 | 153 | ## 新增点赞和点踩功能，使用Redis实现 154 | 155 | 首先了解一下redis的基础知识，数据结构，jedis使用等。 156 | 157 | 编写list，string，hashmap，set，sortset的测试用例，熟悉jedis api。 158 | 159 | 开发点踩和点赞功能，在此之前根据业务封装好jedis的增删改查操作，放在util包中 160 | 161 | 根据需求确定key字段，格式是 like：实体类型：实体id 和 dislike：实体类型：实体id 这样可以将喜欢一条新闻的人存在一个集合，不喜欢的存在另一个集合。通过统计数量可以获得点赞和点踩数。 162 | 163 | 一般点赞点踩操作是先修改redis的值并获取返回值，然后再异步修改mysql数据库的likecount数值。这样既可以保证点赞操作快速完成，也可保证数据一致性。 164 | 165 | 本次开发过程中遇到了请求超时的问题，经过排查之后是漏写了某个接口的服务，导致前端获取不到后端需要传的数据，而前端代码会不断检测这个数据的值以完成后续操作，导致页面无法完成解析。后来回滚到上一个版本后才发现bug所在并解决了该问题。 166 | 167 | ## 新增异步消息功能 新增邮件发送组件 168 | 169 | 在之前的功能中有一些不需要实时执行的操作或者任务，我们可以把它们改造成异步消息来进行发送。 170 | 171 | 具体操作就是使用redis来实现异步消息队列。代码中我们使用事件event来包装一个事件，事件需要记录事件实体的各种信息。 172 | 173 | 我们在async包里开发异步工具类，事件生产者，事件消费者，并且开发一个eventhandler接口，让各种事件的实现类来实现这个接口。 174 | 175 | 事件生产者一般作为一个服务，由业务代码进行调用产生一个事件。而事件消费者我们在代码里使用了单线程循环获取队列里的事件，并且寻找对应的handler进行处理。 176 | 177 | 如此一来，整个异步事件的框架就开发完成了。后面新加入的登录，点赞等事件都可以这么实现。 178 | 179 | 新增邮件功能，主要是引入mail依赖，并且配置好自己的邮箱信息，以及邮件模板，同时在业务代码中加入发邮件的逻辑即可。 180 | 181 | 182 | 183 | 184 | 185 | 186 | 187 | 188 | 189 | 190 | 191 | -------------------------------------------------------------------------------- /src/main/resources/static/scripts/main/component/popupUpload.js: -------------------------------------------------------------------------------- 1 | /** 2 | var oPopupUpload = new PopupUpload({ 3 | 4 | }); 5 | */ 6 | (function (window) { 7 | var PopupUpload = Base.createClass('main.component.PopupUpload'); 8 | var Popup = Base.getClass('main.component.Popup'); 9 | var Upload = Base.getClass('main.component.Upload'); 10 | var Component = Base.getClass('main.component.Component'); 11 | var Util = Base.getClass('main.base.Util'); 12 | 13 | Base.mix(PopupUpload, Component, { 14 | _tpl: [ 15 | '
