springmvc+mybatis创建_创建一个java web项目,以spring mvc整合mybatis框架,实现用户注册功能。 实验

1. 利用idea生成maven的springmvc

2.创建java、resource目录

3 pom文件如下

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.7</maven.compiler.source>
    <maven.compiler.target>1.7</maven.compiler.target>
    <mybatis.version>3.4.1</mybatis.version>
    <mybatis.spring.version>1.3.1</mybatis.spring.version>
    <mysql.version>5.1.38</mysql.version>
 
  </properties>

4 web.xml如下

 
     <servlet>
      <servlet-name>springmc</servlet-name>
       <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
      <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
       </init-param>
       <load-on-startup>1</load-on-startup>
   </servlet>
     <servlet-mapping>
       <servlet-name>springmc</servlet-name>
       <url-pattern>/</url-pattern>
    </servlet-mapping>

5. 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"
       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">
 
 
   <context:component-scan base-package="com.xiaoding"/>
    <bean
            class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
        <property name="messageConverters">
            <list>
                <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"></bean>
                <!--   <ref bean="mappingJacksonHttpMessageConverter" />-->
            </list>
        </property>
    </bean>
 
   <import resource="application-dao.xml"/>
</beans>

6. application-dao.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"

        <!-- 基本属性 url,user,pass -->
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3306/bank?characterEncoding=utf-8"/>
        <property name="username" value="root"/>

        <property name="mapperLocations" value="classpath:mapper/*Mapper.xml"></property>
        <property name="typeAliasesPackage" value="com.xiaoding.domain"></property>
    </bean>
 
 
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.xiaoding.mapper"/>
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
    </bean>
 
 
 
 
</beans>

7.mapper配置如下：

<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.xiaoding.mapper.StudentMapper">
 
    <select id="getStudents"  resultType="Student">
        select * from student
    </select>
 
</mapper>

8.整体文件目录
