Maven中SpringMVC+mybatis整合

本篇文章介绍如何将SpringMVC跟mybatis进行整合
开发环境：JDK1.8+Toncat8.5

1.首先创建一个maven项目，然后引入两个框架所需要的依赖包：
pom.xml:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

2.配置web.xml

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
          http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
           version="3.0">

    
    <context-param>
        <param-name>contextConfigLocationparam-name>
        <param-value>/WEB-INF/spring-mybatis.xmlparam-value>
    context-param>
    
    <filter>
        <filter-name>encodingFilterfilter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>
        <async-supported>trueasync-supported>
        <init-param>
            <param-name>encodingparam-name>
            <param-value>UTF-8param-value>
        init-param>
    filter>
    <filter-mapping>
        <filter-name>encodingFilterfilter-name>
        <url-pattern>/*url-pattern>
    filter-mapping>
    
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
    listener>
    
    <listener>
        <listener-class>org.springframework.web.util.IntrospectorCleanupListenerlistener-class>
    listener>

    
    <servlet>
        <servlet-name>SpringMVCservlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
        <init-param>
            <param-name>contextConfigLocationparam-name>

    <welcome-file-list>
        <welcome-file>/index.jspwelcome-file>
    welcome-file-list>

web-app>

3.在web.xml中我们配置引入了两个配置文件，一个全局Spring配置文件：spring-mybatis.xml，另外一个DispatcherServlet的配置文件：springmvc.xml。mybatis的主要配置要写在全局配置文件spring-mybatis.xml中：
spring-mybatis.xml:

<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:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd ">
    <context:annotation-config/>

    <context:component-scan base-package="com.znbt.*">context:component-scan>

    <bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource"
          destroy-method="close">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://127.0.0.1:3306/crm_db" />
        <property name="username" value="root" />
        <property name="password" value="1" />
    bean>

    
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        
        <property name="mapperLocations" value="classpath*:/mybatis/*Mapper.xml" />
        <property name="configLocation" value="classpath:mybatis/config.xml">property>
    bean>

    <bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate" scope="prototype">
        <constructor-arg index="0" ref="sqlSessionFactory">constructor-arg>
    bean>



    
    <bean id="transactionManager"
          class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    bean>

    
    <tx:annotation-driven proxy-target-class="true" transaction-manager="transactionManager"/>


    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.znbt.dao" />
        <property name="sqlSessionTemplateBeanName" value="sqlSessionTemplate">property>
        <property name="annotationClass" value="org.springframework.stereotype.Repository">property>
    bean>

beans>

其中的dataSource是数据库配置信息；自动扫描mapping.xml文件中的config.xml是自己定义的mybatis的配置文件。

spring-mvc.xml:

<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-4.0.xsd
                        http://www.springframework.org/schema/context
                        http://www.springframework.org/schema/context/spring-context-4.0.xsd
                        http://www.springframework.org/schema/mvc
                        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

    
    <context:component-scan base-package="com.znbt.*" />
    
    <mvc:annotation-driven/>
    
    <mvc:default-servlet-handler/>

    
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp"/>
    bean>

    
    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        
        <property name="defaultEncoding" value="UTF-8"/>
        
        <property name="maxUploadSize" value="32505856"/>
        
        <property name="maxInMemorySize" value="4096"/>
    bean>
beans>

4.在src/main/java下创建一个mybatis文件夹，用来存放mybatis的配置文件和映射文件
mybatis配置文件config.xml（配置文件的名字可以自定义，只要确保能在Spring中找到即可）:

<configuration>

    <settings>
        <setting name="cacheEnabled" value="true" />
        <setting name="lazyLoadingEnabled" value="false" />
        <setting name="useColumnLabel" value="true" />
        <setting name="useGeneratedKeys" value="true" />
        <setting name="defaultExecutorType" value="SIMPLE" />
        <setting name="localCacheScope" value="STATEMENT"/>
    settings>

    <typeAliases>
        <typeAlias type="com.znbt.entity.CustomerEntity" alias="customer">typeAlias>
        <typeAlias type="com.znbt.entity.AreaEntity" alias="area">typeAlias>
        <typeAlias type="com.znbt.entity.PageEntity" alias="page">typeAlias>
    typeAliases>

configuration>

映射文件：customerMapper.xml：

<mapper namespace=" ">
mapper> 

5.然后在相同目录下新建一个日志文件：
log4j.properties（名字必须为log4j）

log4j.rootLogger=INFO,Console,File

#控制台日志
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%p][%t][%d{yyyy-MM-dd HH\:mm\:ss}][%C] - %m%n

#普通文件日志
log4j.appender.File=org.apache.log4j.RollingFileAppender
log4j.appender.File.File=logs/ssm.log
log4j.appender.File.MaxFileSize=10MB
#输出日志，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][%t][%d{yyyy-MM-dd HH\:mm\:ss}][%C] - %m%n

好了，到这整个项目就搭建完毕了，你可以写一些测试代码来测试项目是否搭建成功。
