一.环境搭建

1.创建一个maven项目,使用webapp骨架.

 2.补全项目

新建一个java目录和resources目录,把java目录标记成Sources boot,把resources标记成Resources boot

怎么标记呢,在目录上右击鼠标选择 Mark Directory As 然后选择相应的类型就行了.

3.在register_ssm项目的pom.xml中引入坐标依赖

<properties><spring.version>5.0.2.RELEASE</spring.version><slf4j.version>1.6.6</slf4j.version><log4j.version>1.2.12</log4j.version><mysql.version>5.1.6</mysql.version><mybatis.version>3.4.5</mybatis.version></properties><dependencies><dependency><groupId>org.aspectj</groupId><artifactId>aspectjweaver</artifactId><version>1.6.8</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aop</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version><scope>compile</scope></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>${mysql.version}</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><version>2.5</version><scope>provided</scope></dependency><dependency><groupId>javax.servlet.jsp</groupId><artifactId>jsp-api</artifactId><version>2.0</version><scope>provided</scope></dependency><dependency><groupId>jstl</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency><!-- log start --><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>${log4j.version}</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-api</artifactId><version>${slf4j.version}</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>${slf4j.version}</version></dependency><!-- log end --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>${mybatis.version}</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>1.3.0</version></dependency><dependency><groupId>c3p0</groupId><artifactId>c3p0</artifactId><version>0.9.1.2</version><type>jar</type><scope>compile</scope></dependency>
</dependencies>

4.数据库建立

create table user(
id int primary key auto_increment,
username varchar(20),
password varchar(20),
email    varchar(30),
qqnumber varchar(20),
phone    varchar(11),
sex      int,
birthday TIMESTAMP
);

5.新建一个实体类User

在java目下新建一个com.exia.domain包

在该包下新建一个类,为了方便类中的属性名要和数据库中表的字段名一样.

public class User implements Serializable {private Integer id;private String  username;private String  password;private Integer sex;private String  sexStr;private String  email;private String  qqnumber;private String  phone;@DateTimeFormat(pattern="yyyy-MM-dd")private Date birthday;public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public Integer getSex() {return sex;}public void setSex(Integer sex) {this.sex = sex;}public String getSexStr() {return sexStr;}public void setSexStr(String sexStr) {this.sexStr = sexStr;}public String getEmail() {return email;}public void setEmail(String email) {this.email = email;}public String getQqnumber() {return qqnumber;}public void setQqnumber(String qqnumber) {this.qqnumber = qqnumber;}public String getPhone() {return phone;}public void setPhone(String phone) {this.phone = phone;}public Date getBirthday() {return birthday;}public void setBirthday(Date birthday) {this.birthday = birthday;}@Overridepublic String toString() {return "User{" +"id=" + id +", username='" + username + '\'' +", password='" + password + '\'' +", sex=" + sex +", sexStr='" + sexStr + '\'' +", email='" + email + '\'' +", qqnumber='" + qqnumber + '\'' +", phone='" + phone + '\'' +", birthday=" + birthday +'}';}
}

6.编写dao接口

新建一个com.exia.dao 包

然后新建一个接口IUserDao

这里使用注解的方式 如果sql语句复杂可以使用xml的方式.

package com.exia.dao;import com.exia.domain.User;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;@Repository
@Mapper
public interface IUserDao {@Insert("insert into user(username,password,email,qqnumber,phone,sex,birthday) values(#{username},#{password},#{email},#{qqnumber},#{phone},#{sex},#{birthday})")public void registerUser(User user) throws Exception;
}

7.编写service层

新建两个包

com.exia.service

com.exia.service.impl

在 com.exia.service下新建一个接口

package com.exia.service;import com.exia.domain.User;public interface IUserService {//用户注册public void registerUser(User user) throws  Exception;
}

在com.exia.service.impl下新建实现类

package com.exia.service.impl;import com.exia.dao.IUserDao;
import com.exia.domain.User;
import com.exia.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;@Service
@Transactional
public class UserServiceImpl implements IUserService {@Autowiredprivate IUserDao userDao;//用户注册public void registerUser(User user) throws Exception {userDao.registerUser(user);System.out.println("registerUser...");}
}

二.编写spring的配置文件

在resources文件中的新建applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context"xmlns:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd"><!--配置扫描service和dao包--><context:component-scan base-package="com.exia.service" /><context:component-scan base-package="com.exia.dao"     />
</beans>

三.spring整合springmvc

1.在web.xml中配置前端控制器

<!--1.配置前段控制器--><servlet><servlet-name>dispatcherServlet</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!-- 配置初始化参数，创建完DispatcherServlet对象，加载springmvc.xml配置文件 --><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springmvc.xml</param-value></init-param><!-- 服务器启动的时候，让DispatcherServlet对象创建 --><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>dispatcherServlet</servlet-name><url-pattern>*.do</url-pattern></servlet-mapping>

2.在web.xml中解决中文乱码问题

 <!--2.解决中文乱码问题--><filter><filter-name>characterEncodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param></filter><filter-mapping><filter-name>characterEncodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping>

3.在resources目录下新建springmvc的配置文件springmvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:mvc="http://www.springframework.org/schema/mvc"xmlns:context="http://www.springframework.org/schema/context"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd"><!--扫描controller下的包--><context:component-scan base-package="com.exia.controller" /><!--配置视图解析器--><bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"><!--jsp文件所在的目录--><property name="prefix" value="/pages/"/><!--文件的后缀名--><property name="suffix" value=".jsp" /></bean><!-- 设置静态资源不过滤 --><mvc:resources location="/css/" mapping="/css/**" /><mvc:resources location="/img/" mapping="/img/**" /><!--开启springmvc注解的支持--><mvc:annotation-driven /></beans>

4.新建一个com.exia.controller的包 在其中新建一个类UserController

@Controller
@RequestMapping("/user")
public class UserController {@Autowiredprivate IUserService userService;@RequestMapping("/register.do")public String Register(User user) throws Exception {userService.registerUser(user);return "success";}
}

5.Spring整合SpringMVC的框架

整合的目的:使controller中能成功调用service对象中的方法.

在项目启动的时候，就去加载applicationContext.xml的配置文件，在web.xml中配置
ContextLoaderListener监听器（该监听器只能加载WEB-INF目录下的applicationContext.xml的配置文
件）。

在web.xml中加入如下代码

<!--3.配置监听器--><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></context-param>

6.配置默认页面

在web.xml中加入如下代码

  <!--配置默认加载页面--><welcome-file-list><welcome-file>index.html</welcome-file><welcome-file>index.htm</welcome-file><welcome-file>index.jsp</welcome-file><welcome-file>default.html</welcome-file><welcome-file>default.htm</welcome-file><welcome-file>default.jsp</welcome-file></welcome-file-list>

四.spring整合mybatis框架

目的：把SqlMapConfig.xml配置文件中的内容配置到applicationContext.xml配置文件中
1.在applicationContext.xml中加入如下代码

 <!--配置C3P0的连接池对象--><bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"><property name="driverClassName" value="com.mysql.jdbc.Driver"/><property name="url" value="jdbc:mysql:///ssm"/><property name="username" value="root" /><property name="password" value="123456" /></bean><!--把sqlsessionfactory交给spring ioc管理--><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean" ><property name="dataSource" ref="dataSource"/></bean><!--配置扫描dao的包--><bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value="com.exia.dao" /></bean>

2.配置Spring的声明式事务管理

在applicationContext.xml中加入如下配置

    <!--配置spring的声明式事务--><bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource" /></bean><!--开启事务的注解支持--><tx:annotation-driven transaction-manager="transactionManager"/>

五.前端页面

1.register.jsp

action设置成"${pageContext.request.contextPath}/user/register.do"

输入框的name一定要和 User类中的属性保持一致,这样springmvc会自动把数据封装到对应方法的参数User中.

<form action="${pageContext.request.contextPath}/user/register.do" method="post"><table><tr><td class="td_left"><label for="username">用户名</label></td><td class="td_right"><input type="text" name="username" placeholder="请输入用户名"id="username"></td></tr><tr><td class="td_left"><label for="password">密码</label></td><td class="td_right"><input type="password" name="password" placeholder="请输入密码"id="password"></td></tr><tr><td class="td_left"><label for="Email">Email</label></td><td class="td_right"><input type="email" name="email" placeholder="请输入Email" id="Email"></td></tr><tr><td class="td_left"><label for="rename">QQ号</label></td><td class="td_right"><input type="text" name="qqnumber" placeholder="请输入QQ号" id="rename"></td></tr><tr><td class="td_left"><label for="Telphone">手机号</label></td><td class="td_right"><input type="text" name="phone" placeholder="请输入您的手机号"id="Telphone"></td></tr><tr><td class="td_left"><label>性别</label></td><td class="td_right"><input type="radio" name="sex" value="0" checked> 男<input type="radio" name="sex" value="1"> 女</td></tr><tr><td class="td_left"><label for="Birthday">出生日期</label></td><td class="td_right"><input type="date" name="birthday" id="Birthday"></td></tr><tr><td colspan="2" align="center"><input type="submit" value="注册" id="btn_sub"></td></tr></table></form>

2.index.jsp

在index.jsp中跳转到注册页面

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head><title>Title</title>
</head>
<body>
<%--    <a href="user/register.do">test</a>--%>
<jsp:forward page="register.jsp"></jsp:forward>
</body>
</html>

3.在webapp下新建一个pages目录,在其中创建一个success.jsp页面

<%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %>
<html>
<head><title>Title</title>
</head>
<body>
<h1>插入成功</h1>
</body>
</html>
