配置pom用到的框架和版本： spring 5.0.5.RELEASE mybatis 3.4.0 mysql 5.1.35 log4j 1.2.17 mybatis-spring 1.3.2 jdk 1.8

1、 配置 pom.xml

import change -> ok

2、在src->main 下新建 resources ， 右键make directory as -> Resources Root

3、resources -> 新建 applicationContent.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-3.0.xsd

http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
"><!-- 1.配置jdbc文件 --><bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="locations" value="classpath:jdbc.properties"/></bean><!-- 2.扫描的包路径，这里不扫描被@Controller注解的类 --><!--使用<context:component-scan/> 可以不在配置<context:annotation-config/> --><context:component-scan base-package="com.zgr"><context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/></context:component-scan><import resource="classpath:spring-mybatis.xml" /></beans>

4、resources -> 新建 spring-mvc.xml

<?xml version="1.0" encoding="UTF-8" ?>
<beansxmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:p="http://www.springframework.org/schema/p"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc.xsd"><!-- 扫描controller（controller层注入） --><context:component-scan base-package="com.zgr.controller" use-default-filters="false"><context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/></context:component-scan><mvc:annotation-driven /><!-- 内容协商管理器  --><!--1、首先检查路径扩展名（如my.pdf）；2、其次检查Parameter（如my?format=pdf）；3、检查Accept Header--><bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean"><!-- 扩展名至mimeType的映射,即 /user.json => application/json --><property name="favorPathExtension" value="true"/><!-- 用于开启 /userinfo/123?format=json 的支持 --><property name="favorParameter" value="true"/><property name="parameterName" value="format"/><!-- 是否忽略Accept Header --><property name="ignoreAcceptHeader" value="false"/><property name="mediaTypes"> <!--扩展名到MIME的映射；favorPathExtension, favorParameter是true时起作用  --><value>json=application/jsonxml=application/xmlhtml=text/html</value></property><!-- 默认的content type --><property name="defaultContentType" value="text/html"/></bean><!-- 当在web.xml 中   DispatcherServlet使用 <url-pattern>/</url-pattern> 映射时，能映射静态资源 --><mvc:default-servlet-handler /><!-- 静态资源映射 --><mvc:resources mapping="/static/**" location="/WEB-INF/static/"/><!-- 对模型视图添加前后缀 --><bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"p:prefix="/WEB-INF/pages/" p:suffix=".jsp"/></beans>

5、resources -> 新建 spring-mybatis.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:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd"><!-- 3.配置数据源 ，使用的alibba的数据库--><bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"><!-- 基本属性 url、user、password --><property name="driverClassName" value="${jdbc_driverClassName}"/><property name="url" value="${jdbc_url}"/><property name="username" value="${jdbc_username}"/><property name="password" value="${jdbc_password}"/><!-- 配置初始化大小、最小、最大 --><property name="initialSize" value="10"/><property name="minIdle" value="10"/><property name="maxActive" value="50"/><!-- 配置获取连接等待超时的时间 --><property name="maxWait" value="60000"/><!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 --><property name="timeBetweenEvictionRunsMillis" value="60000" /><!-- 配置一个连接在池中最小生存的时间，单位是毫秒 --><property name="minEvictableIdleTimeMillis" value="300000" /><property name="validationQuery" value="SELECT 'x'" /><property name="testWhileIdle" value="true" /><property name="testOnBorrow" value="false" /><property name="testOnReturn" value="false" /><!-- 打开PSCache，并且指定每个连接上PSCache的大小  如果用Oracle，则把poolPreparedStatements配置为true，mysql可以配置为false。--><property name="poolPreparedStatements" value="false" /><property name="maxPoolPreparedStatementPerConnectionSize" value="20" /><!-- 配置监控统计拦截的filters --><property name="filters" value="wall,stat" /></bean><!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource" /><!-- 扫描entity包 使用别名 --><property name="typeAliasesPackage" value="com.zgr.domain" /><!-- 自动扫描mapping.xml文件 --><property name="mapperLocations" value="classpath:mapper/*.xml"></property></bean><!-- DAO接口所在包名，Spring会自动查找其下的类 ,自动扫描了所有的XxxxMapper.xml对应的mapper接口文件,只要Mapper接口类和Mapper映射文件对应起来就可以了--><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value="com.zgr.dao" /><property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property></bean><!-- (事务管理)transaction manager, use JtaTransactionManager for global tx --><!-- 配置事务管理器 --><bean id="transactionManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource" /></bean><!--======= 事务配置 End =================== --><!-- 配置基于注解的声明式事务 --><!-- enables scanning for @Transactional annotations --><tx:annotation-driven transaction-manager="transactionManager" /></beans>

6、 resources -> 新建 log4j.properties

# Root logger option
#ALL<DEBUG<INFO<WARN<ERROR<FATAL<OFF
log4j.rootLogger=INFO, stdout, file# Redirect log messages to console
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n# Rirect log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=/logs/log4j.log
log4j.appender.file.MaxFileSize=5MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%nlog4j.logger.org.springframework=ERROR

7、 resources -> 新建 jdbc.properties

jdbc_driverClassName =com.mysql.jdbc.Driver
jdbc_url=jdbc:mysql://localhost:3306/ssmdemo?useUnicode=true&characterEncoding=utf8
jdbc_username=root
jdbc_password=root

环境搭建好了，可以写个demo试试看

• UserService.java
