使用c3p0与Dbutils开发用户注册功能：
用户在register.jsp表单成功后，页面跳转到login.html，数据库中会存放用户注册的信息

数据库表hibernatest.user
【项目结构】
注册表单页面register.jsp
<form action="UserRegServlet" method="post"> <div class="register-box"> <label for="username" class="username_label"> 用 户 名 <input maxlength="20" name="userName" type="text" placeholder="您的用户名和登录名" /> </label> <div class="tips"> </div> </div> <div class="register-box"> <label for="username" class="other_label"> 设 置 密 码 <input maxlength="20" type="password" name="pwd" placeholder="建议至少使用两种字符组合" /> </label> <div class="tips"> </div> </div> <div class="register-box"> <label for="username" class="other_label"> 确 认 密 码 <input maxlength="20" type="password" placeholder="请再次输入密码" /> </label> <div class="tips"> </div> </div> <div class="register-box"> <label for="username" class="username_label"> 邮箱 <input maxlength="20" name="userName" type="text" placeholder="您的邮箱" /> </label> <div class="tips"> </div> </div> <div class="register-box"> <label for="username" class="username_label"> 真是姓名 <input maxlength="20" name="userName" type="text" placeholder="您的真是姓名" /> </label> <div class="tips"> </div> </div> <div class="register-box"> <label for="username" class="username_label"> 手机号 <input maxlength="20" name="telephone" type="text" placeholder="您的手机号" /> </label> <div class="tips"> </div> </div> <div class="arguement"> <input type="checkbox" id="xieyi" /> 阅读并同意 <a href="javascript:void(0)">《错题用户注册协议》</a> <a href="login.html">已有账号,立即登录</a> <div class="tips"> </div> </div> <div class="submit_btn"> <button type="submit" id="submit_btn"> 立 即 注 册 </button> </div> </form>
用户实体层
private String id; private String username; private String password; private String name; private String email; private String telephone;
用户提交表单，发送请求UserAction_register到Web层userService.java
public String register() throws Exception { //自动封装User //没有的手动封装 user.setId(UUID.randomUUID().toString()); //传递数据 UserService userService = new UserService(); userService.addUser(user); System.out.println("123"); return "toLogin"; }
Service层接收到WeB层发送过来的请求后，进行处理，并发送到Dao层UserDao.java进行数据处理
public void addUser(User user) throws SQLException { System.out.println("456"); QueryRunner runner = new QueryRunner(C3p0DataSourceUtils.getDataSource()); String sql = "insert into user values(?,?,?,?,?,?)"; runner.update(sql,user.getId(),user.getUsername(),user.getPassword(),user.getName(),user.getEmail(),user.getTelephone()); }
使用c3p0链接MySQL数据库在c3p0-config.xml中进行配置
<default-config> <property name="driverClass">com.mysql.jdbc.Driver</property> <property name="jdbcUrl">jdbc:mysql:///hibernatest</property> <property name="user">root</property> <property name="password">123456</property> <property name="initialPoolSize">5</property> <property name="maxPoolSize">20</property> </default-config>
