一.简介
这篇文章是记录我自己手动搭建基于maven的SSM（spring+springMVC+mybatis）框架项目的整个过程，目的是为了加深印象和方便以后查阅以及整理思路。
二.开发环境准备
（1）系统：Windows10（专业版）
（2）eclispe版本：Eclipse Java EE IDE for Web Developers.（4.6.2）
（3）maven版本：apache-maven-3.5.3
（4）jdk版本：jdk1.8.0_172
（5）tomcat版本：apache-tomcat-7.0.90
（6）数据库：oracle（11.2.0.4.0）
三.搭建项目
（1）创建maven项目：
默认next到这个界面：
继续点击next到这个界面：输入web选择后缀是maven-archetype-webapp的选项，然后继续点击next
到了这个界面输入图中Group id,Artifac id两个ID(必须输入,名称自定义),然后点击next：
整个maven项目结构暂时完成：
接下来调整项目结构：
这个时候我们看到JRE System Libryary后面显示的是[J2SE-1.5],并且没有maven项目的src/main/java等文件夹，原因是我们没有选择正确的JDK版本，这时候我们需要调整对应的JRE环境，在工程上右键Build Path-Configure Build Path，在Libraries下选中JRE，右侧edit，选择我们自己的jdk版本：
点击apply后点击ok后完成jdk配置，你会神奇的发下项目结构变了，但是还是缺少一个src/test/resources文件夹，没关系，这里我们自己手动创建一个就是了
创建完成，项目结构调整完成
（2）添加pom依赖，下载SSM框架所需jar包

Ctrl+s保存后就能看到相应的依赖包：
（3）配置文件
1.在resources文件夹下面创建spring-mybatis.xml，配置好该xml文件内容：
<?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:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.1.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
<!-- 自动扫描 -->
<context:component-scan base-package="com.zd.maven" />
<!-- 引入配置文件 -->
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:jdbc.properties</value>
<value>classpath:log4j.properties</value>
</list>
</property>
</bean>
<!-- 配置数据源 -->
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driver}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!-- 自动扫描mapping.xml文件 -->
<property name="mapperLocations" value="classpath:com/zd/maven/map/*.xml"></property>
<!-- 自动扫描实体类 -->
<property name="configLocation" value="classpath:mybatis-config.xml"></property>
</bean>
<!-- DAO接口所在包名，Spring会自动查找其下的类 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.zd.maven.dao" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
</bean>
<!-- 事务管理 -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
</beans>
继续在resources目录下创建spring-mvc.xml文件，配置好文件内容：
<?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:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.1.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
<!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 -->
<context:component-scan base-package="com.zd.maven.controller" />
<!-- 这个配置是为了让返回的值转为json格式 -->
<mvc:default-servlet-handler/><mvc:annotation-driven/>
<!-- 定义跳转的文件的前后缀 ，视图模式配置-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- controller中return时会自动加上前缀和后缀，变成一个完整的url -->
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
创建jdbc.properties文件，并配置好相应的内容：
jdbc.driver=oracle.jdbc.driver.OracleDriver
jdbc.url=jdbc:oracle:thin:@localhost:1521:orcl
jdbc.username=scott
jdbc.password=admin同时创建log4j.properties文件，配置好文件内容：
log4j.rootLogger=INFO,Console,File
#定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#可以灵活地指定日志输出格式，下面一行是指定具体的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
#文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定输出目录
log4j.appender.File.File = logs/ssm.log
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n最后我们再来修改一下啊web.xml文件，基本的配置就完成了：
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>

<!-- Spring和mybatis的配置文件 -->

</welcome-file-list>
</web-app>
（4）编写服务端代码，结构如下：
注意，在编写代码之前，可首先把数据库表建好，以便之后可以访问数据库拿数据到页面展示
1.UserDTO.java:
package com.zd.maven.dto;
public class UserDTO {
private String name;
private int age;
private String birthday;
private String address;
private String phoneNo;
private String sex;
private String id;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getBirthday() {
return birthday;
}
public void setBirthday(String birthday) {
this.birthday = birthday;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getPhoneNo() {
return phoneNo;
}
public void setPhoneNo(String phoneNo) {
this.phoneNo = phoneNo;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
}
2.UserService.java:
package com.zd.maven.service;
import com.zd.maven.dto.UserDTO;
public interface UserService {
public UserDTO selectUserInfo(String id);
}
3.UserServiceImpl.java:
package com.zd.maven.serviceimpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.util.StringUtils;
import com.zd.maven.dao.UserDao;
import com.zd.maven.dto.UserDTO;
import com.zd.maven.service.UserService;
@Service
public class UserServiceImpl implements UserService {
@Autowired
private UserDao userDao;
public UserDTO selectUserInfo(String id) {
System.out.println(id);
if (StringUtils.hasText(id)) {
System.out.println("id不为空");
return userDao.getUserDTO(id);
}
return null;
}
}
4.UserDao.java:
package com.zd.maven.dao;
import com.zd.maven.dto.UserDTO;
public interface UserDao {
public UserDTO getUserDTO(String id);
public int deleteUserDTO(String id);
public int insertUser(UserDTO userDTO);
}
5.UserDaoMapper.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.zd.maven.dao.UserDao">

</select>
<delete id="deleteUserDTO" parameterType="java.lang.String">

#{birthday,jdbcType=VARCHAR},#{age,jdbcType=VARCHAR},#{phoneNo,jdbcType=VARCHAR},#{address,jdbcType=VARCHAR})
</insert>
<!-- <update id="updateByPrimaryKeySelective" parameterType="com.java.zxf.domain.User">

<set>
<if test="userName != null">

</if>
<if test="userBirthday != null">

</if>
</set>
where id = #{id,jdbcType=VARCHAR}
</update>
<update id="updateByPrimaryKey" parameterType="com.java.zxf.domain.User">
update user
set user_name = #{userName,jdbcType=VARCHAR},
user_gender = #{userGender,jdbcType=VARCHAR},
user_birthday = #{userBirthday,jdbcType=VARCHAR}
where id = #{id,jdbcType=VARCHAR}
</update> -->
</mapper>
6.UserController.java:
package com.zd.maven.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import com.zd.maven.dto.UserDTO;
import com.zd.maven.service.UserService;
@Controller
public class UserController {
@Autowired
private UserService userService;
@RequestMapping(value = "/getUserInfo", method = RequestMethod.GET)
@ResponseBody
public Object getUserInfo(String id) {
System.out.println("进入方法");
UserDTO userDTO = userService.selectUserInfo(id);
System.out.println("此人的电话号码为：" + userDTO.getPhoneNo());
return userDTO;
}
}
(5)项目构建：
