SSM项目整合第一步 注册：
项目目录：
一、数据库建表：
源码：
1 SET FOREIGN_KEY_CHECKS=0; 2 3 -- ---------------------------- 4 -- Table structure for t_user 5 -- ---------------------------- 6 DROP TABLE IF EXISTS `t_user`; 7 CREATE TABLE `t_user` ( 8 `user_id` int(11) NOT NULL AUTO_INCREMENT, 9 `user_name` varchar(32) NOT NULL, 10 `user_pass` varchar(36) NOT NULL, 11 `user_tel` int(11) DEFAULT NULL, 12 `user_real_name` varchar(32) DEFAULT NULL, 13 PRIMARY KEY (`user_id`) 14 ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8; 15 16 -- ---------------------------- 17 -- Records of t_user 18 -- ---------------------------- 19 INSERT INTO `t_user` VALUES ('1', '123', '123456', null, null); 20 INSERT INTO `t_user` VALUES ('2', 'Lucky', 'admin', '123', 'admin');
二、建立实体类映射字段：
后端实体类字段映射：
已下配置会将字段uesr_id 自动转换为userId 将_i 转换为大写I
applicationContext.xml：
<!-- 加载mybatis-config配置文件，里面设置别名 --> <property name="configLocation" value="classpath:mybatis-config.xml"/>
mybatis-config.xml：
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE configuration 3 PUBLIC "-//mybatis.org//DTD Config 3.0//EN" 4 "http://mybatis.org/dtd/mybatis-3-config.dtd"> 5 <configuration> 6 <settings> 7 <setting name="mapUnderscoreToCamelCase" value="true"/> 8 </settings> 9 </configuration>
前端实体类字段映射：
三、处理流程：
四、前端页面显示：
spring表头：
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form" %>
spring表单：
错误信息：
1 <%@taglib uri="http://www.springframework.org/tags/form" prefix="form" %> 2 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 3 <!-- saved from url=(0049)http://localhost:8080/HouseRent/page/register.jsp --> 4 <HTML xmlns="http://www.w3.org/1999/xhtml"> 5 <HEAD><TITLE>布谷租房 - 用户注册</TITLE> 6 <META content="text/html; charset=utf-8" http-equiv=Content-Type> 7 <LINK 8 rel=stylesheet type=text/css href="../css/style.css"> 9 <META name=GENERATOR content="MSHTML 8.00.7601.17514"> 10 </HEAD> 11 <BODY> 12 <DIV id=header class=wrap> 13 <DIV id=logo><IMG src="../images/logo.gif"></DIV> 14 </DIV> 15 <DIV id=regLogin class=wrap> 16 <DIV class=dialog> 17 <DL class=clearfix> 18 <DT>新用户注册</DT> 19 <DD class=past>填写个人信息</DD> 20 </DL> 21 <DIV class=box> 22 <form:form action="/user/doreg" modelAttribute="userError" method="post"> 23 <DIV class=infos> 24 <TABLE class=field> 25 <TBODY> 26 <TR> 27 <TD class=field>用 户 名：</TD> 28 <TD><INPUT class=text type=text name=name><form:errors path="name"></form:errors></TD> 29 </TR> 30 <TR> 31 <TD class=field>密 码：</TD> 32 <TD><INPUT class=text type=password name=password><form:errors path="password"></form:errors></TD> 33 </TR> 34 <TR> 35 <TD class=field>确认密码：</TD> 36 <TD><INPUT class=text type=password name=repassword></TD> 37 </TR> 38 <TR> 39 <TD class=field>电 话：</TD> 40 <TD><INPUT class=text type=text name=telephone><form:errors path="telephone"></form:errors></TD> 41 </TR> 42 <TR> 43 <TD class=field>用户姓名：</TD> 44 <TD><INPUT class=text type=text name=username></TD> 45 </TR> 46 </TBODY> 47 </TABLE> 48 <DIV class=buttons> 49 <INPUT value=立即注册 type="submit"> 50 </DIV> 51 </DIV> 52 </form:form> 53 </DIV> 54 </DIV> 55 </DIV> 56 <DIV id=footer class=wrap> 57 <DL> 58 <DT>布谷租房 © 2010 布谷租房 京ICP证1000001号</DT> 59 <DD>关于我们 · 联系方式 · 意见反馈 · 帮助中心</DD> 60 </DL> 61 </DIV> 62 </BODY> 63 </HTML>
如果页面没有css样式 此时处理静态文件才会显示：
1 <!--处理静态文件 --> 2 <mvc:resources location="/scripts/" mapping="/scripts/**"/> 3 <mvc:resources location="/css/" mapping="/css/**"/> 4 <mvc:resources location="/images/" mapping="/images/**"/>
五、插入乱码解决：
WEB-INF/web.xml：
1 <!-- 设置编码为UTF-8 --> 2 <filter> 3 <description>字符集过滤器</description> 4 <filter-name>encodingFilter</filter-name> 5 <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> 6 <init-param> 7 <description>字符集编码</description> 8 <param-name>encoding</param-name> 9 <param-value>UTF-8</param-value> 10 </init-param> 11 </filter> 12 <filter-mapping> 13 <filter-name>encodingFilter</filter-name> 14 <url-pattern>/*</url-pattern> 15 </filter-mapping>
mysql.properties：
