【SSM 6】Spring+SpringMVC+Mybatis框架搭建步骤
一、整体概览
首先看maven工程的创建
二、各层的文件配置
2.1，SSM父工程

2.5.2，spring整合配置文件
2.5.2.1，Mybatis
目前无，当使用到分页插件，或者额外的功能配置时，需要进行配置，下面以配置分页插件为例：
<span style="font-family:KaiTi_GB2312;font-size:18px;"><?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis3 config.dtd"> <configuration>
<!-- 配置分页插件 -->
<plugins>
<plugin interceptor="com.github.pagehelper.PageHelper">
<!-- 设置数据库类型Oracle，MySQL，MarinDBName，SQLite，PostareSQL六种数据库 -->
<property name="dialect" value="mysql"/>
</plugin>
</plugins>
</configuration></span>
jdbc.properties：数据库连接信息配置，主要包括jdbc.driver数据库驱动；jdbc.url数据库连接地址；jdbc.username连接用户名称；jdbc.password用户密码
2.5.2.2，spring配置
（为了分层解耦，为每一层，每一个用途的spring配置，都进行了单独配置）
1，首先：applicationContext-dao.xml，在这一层，主要配置数据库连接池（用到jdbc.properties数据库连接信息），Mybatis配置信息，加载Mybatis的mapper对象
<span style="font-family:KaiTi_GB2312;font-size:18px;"><beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
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-4.0.xsd

http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> <!-- 数据库连接池 -->
<!-- 加载配置文件 -->
<context:property-placeholder location="classpath:resource/*.properties" />
<!-- 数据库连接池 -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
destroy-method="close">
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="driverClassName" value="${jdbc.driver}" />
<property name="maxActive" value="10" />
<property name="minIdle" value="5" />
</bean>
<!-- 让spring管理sqlsessionfactory-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 数据库连接池 -->
<property name="dataSource" ref="dataSource" />
<!-- 加载mybatis的全局配置文件 -->
<property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml" />
</bean>
<!-- 配置扫描包，加载mapper代理对象 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="Angel.mapper" /> </bean>
</beans></span>
2，applicationContext-service.xml，主要就是配置扫描包，一句话：
<span style="font-family:KaiTi_GB2312;font-size:18px;"><!-- 扫描包，加载service实现类 -->
<context:component-scan base-package="Angel.service"></context:component-scan>
</span>
3，applicationContext-trans.xml事务传播配置，AOP切面配置
<span style="font-family:KaiTi_GB2312;font-size:18px;"><beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"

</bean>

</tx:advice>
<!-- 切面 -->
<aop:config>
<aop:advisor advice-ref="txAdvice"
pointcut="execution(* Angel.service.*.*(..))" />
</aop:config>
</beans>
</span>
2.5.2.3，springMVC配置
<span style="font-family:KaiTi_GB2312;font-size:18px;"><?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"

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-4.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <context:component-scan base-package="Angel.controller" />
<mvc:annotation-driven />
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"></property>
<property name="suffix" value=".jsp" />
</bean> <!-- 资源映射 -->
<mvc:resources location="/WEB-INF/css/" mapping="/css/**" />
<mvc:resources location="/WEB-INF/js/" mapping="/js/**" /> <!-- 当有文件上传需要时，定义文件上传解析器，在同时，也需要在pom文件中添加上传jar的依赖 -->
<!--<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- 设定默认编码 -->
<property name="defaultEncoding" value="UTF-8"></property>
<!-- 设定文件上传的最大值5MB，5*1024*1024 -->
<property name="maxUploadSize" value="5242880"></property>
</bean>--> </beans>
</span>
2.5.2.4，web.xml配置
主要包括，SpringMVC前端控制器的启动，spring容器的启动配置，post乱码过滤
<span style="font-family:KaiTi_GB2312;font-size:18px;"><?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</web-app></span>
三、具体实例
3.1，pojo实例类
TbUser.java(篇幅所限，set和get方法略去)
<span style="font-family:KaiTi_GB2312;font-size:18px;">package Angel.pojo;
import java.util.Date;
public class TbUser {
private Long id;
private String username;
private String password;
private String phone;
private String email;
private Date created;
private Date updated;</span>
3.2，mapper
3.2.1，mapper接口类TbUserMapper.java
<span style="font-family:KaiTi_GB2312;font-size:18px;">package Angel.mapper;
import Angel.pojo.TbUser;
public interface TbUserMapper {
TbUser selectByName(String Name);
}</span>
3.2.2，sql实现文件TbUserMapper.xml
<span style="font-family:KaiTi_GB2312;font-size:18px;"></pre><pre name="code" class="html"><?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="Angel.mapper.TbUserMapper" >
<resultMap id="BaseResultMap" type="Angel.pojo.TbUser" >
<id column="id" property="id" jdbcType="BIGINT" />
<result column="username" property="username" jdbcType="VARCHAR" />
<result column="password" property="password" jdbcType="VARCHAR" />

<result column="email" property="email" jdbcType="VARCHAR" />
<result column="created" property="created" jdbcType="TIMESTAMP" />
<result column="updated" property="updated" jdbcType="TIMESTAMP" />
</resultMap> <select id="selectByName" resultMap="BaseResultMap" parameterType="java.lang.String" >
select
id, username, password,phone, email, created, updated
from tb_user
where username = #{username,jdbcType=VARCHAR}
</select>
</mapper></span>
3.3，service
UserServiceImpl.java（接口省略）
<span style="font-family:KaiTi_GB2312;font-size:18px;">package Angel.service.impl; import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service; import Angel.mapper.TbUserMapper;
import Angel.pojo.TbUser;
import Angel.service.UserService; @Service(value="userService")
public class UserServiceImpl implements UserService { @Autowired
private TbUserMapper userMapper; @Override
public TbUser selectByName(String Name) { return userMapper.selectByName(Name);
}
}
</span>
3.4，web-UserController.java
<span style="font-family:KaiTi_GB2312;font-size:18px;">package Angel.controller; import java.io.IOException;
import java.io.PrintWriter; import javax.servlet.http.HttpServletResponse; import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping; import Angel.pojo.TbUser;
import Angel.service.UserService; import com.fasterxml.jackson.databind.ObjectMapper; @Controller
public class UserController { @Autowired
private UserService userService; @RequestMapping("/user/find/{name}")
public void insertUser(@PathVariable("name") String name,HttpServletResponse response) throws IOException { TbUser user=userService.selectByName(name); ObjectMapper objectMapper=new ObjectMapper();
response.setContentType("application/json;charset=UTF-8");
String json="";
PrintWriter out=response.getWriter();
if(user!=null){
json=objectMapper.writeValueAsString(user);
out.write(json);
}else{
out.write("error");
}
}
}</span>
3.5，JSP页面
<span style="font-family:KaiTi_GB2312;font-size:18px;"><%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"+ request.getServerName() + ":" + request.getServerPort()+ path + "/";
%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<script type="text/javascript">
function findUser(){
var username=$("#username").val();
$.post('<%=basePath%>user/find/'+username,function(data){
//测试框架效果，输入的用户，在数据库中存在相应数据，因此未做判空处理
if(data!="error"){
var detailInfo="username:"+data.username+" phone:"+data.phone+" ...";
$("#detail").text(detailInfo);
}else{
$.messager.alert("info","查询用户出错！")
}
});
}
</script>
</body>
</html>
</span>

四、总结
虽然用maven减少了jar下载引用的负担，但是，从SSM框架的搭建可以看出，引入了特别多的依赖，而且，当我在父工程进行引用后，在各个子模块需要用到的时候，还需要再次依赖引用，有什么方法可以解决这种依赖引用呢，接下来介绍spring boot
