Spring+SpringMvc+Mybatis框架搭建的详细步骤
Java2EE--Java企业版应用最基本的框架，也是最常用的框架SSM(Spring+SpringMvc+Mybatis)。开发工具：Eclipse、MyEclipse、Intellij IDEA等。
1、使用开发工具新建web项目，web-project。实则也是maven项目
2、这里使用MyEclipse进行创建。
2.1、新建文件夹MyWorkSpace作为MyEclipse的工作空间，当用MyEclipse打开的时候，会在本地生成一个.metadata和RemoteSystemsTempFiles文件夹(在工作空间）
2.2、新建web-project
2.3、引入maven需要的jar包
修改pom.xml文件，直接把下面的内容粘到pom.xml里面替换原有的properties和dependencies：
<properties>
<!-- 文件拷贝时的编码 -->
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<!-- 编译时的编码 -->
<maven.compiler.encoding>UTF-8</maven.compiler.encoding>
<!-- spring版本号 -->
<spring.version>4.3.0.RELEASE</spring.version>
<spring-data-redis.version>1.7.1.RELEASE</spring-data-redis.version>
<!--mysql的版本号 -->
<mysql.version>5.1.39</mysql.version>
<!-- mybatis版本号 -->
<mybatis.version>3.4.0</mybatis.version>
<mybatis-spring.version>1.3.0</mybatis-spring.version>
<!-- log4j日志文件管理包版本 -->
<log4j.version>2.1</log4j.version>
</properties>

2.4、.在src/main/resources目录下添加3个配置文件
2.4.1、 jdbc.properties（JDBC属性文件）
driver=com.mysql.jdbc.Driver url=jdbc:mysql://127.0.0.1:3306/test2?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&allowMultiQueries=true&serverTimezone=PRC&useSSL=false username=root password=zh123456 #定义初始连接数 initialSize=0 #定义最大连接数 maxActive=20 #定义最大空闲 maxIdle=20 #定义最小空闲 minIdle=1 #定义最长等待时间 maxWait=60000
2.4.2、spring-mybatis.xml(主要进行自动扫描，自动注入，配置数据库)
<?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="cn.com"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" /> </context:component-scan> <!-- 加载配置文件 --> <!-- 引入配置文件 --> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location" value="classpath:jdbc.properties" /> </bean> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="${driver}" /> <property name="url" value="${url}" /> <property name="username" value="${username}" /> <property name="password" value="${password}" /> <!-- 初始化连接大小 --> <property name="initialSize" value="${initialSize}"></property> <!-- 连接池最大数量 --> <property name="maxActive" value="${maxActive}" ></property> <!-- 连接池最大空闲 --> <property name="maxIdle" value="${maxIdle}" ></property> <!-- 连接池最小空闲 --> <property name="minIdle" value="${minIdle}" ></property> <!-- 获取连接最大等待时间 --> <property name="maxWait" value="${maxWait}" ></property> </bean> <!-- spring和mybatis完美整合，不需要mybatis的配置映射文件 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!-- 自动扫描mapping.xml文件 --> <property name="mapperLocations" value="classpath:sql/*.xml"></property> </bean> <!-- DAO接口所在的包名，spring会自动查找其下的类，！注意这句 value="sqlSessionFactory"，不是ref而是value --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="cn.com.dao" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> </bean> </beans>
2.4.3、log4j2.xml ---日志备份文件
<?xml version="1.0" encoding="UTF-8"?> <configuration status="off"> <properties> <property name="LOG_HOME">${sys:catalina.home}/webAppLogs</property> <!-- 日志备份目录 --> <property name="BACKUP_HOME">backup</property> <property name="SERVER_NAME">dataSync</property> <property name="EVERY_FILE_SIZE">5M</property><!-- 日志切割的最小单位 --> <property name="OUTPUT_LOG_LEVEL">DEBUG</property><!-- 日志输出级别 --> <property name="log.user.active.folder">c:\\crt</property> <property name="log.user.active.file">active</property> <property name="log.user.active.path">${log.user.active.folder}/${log.user.active.file}/${log.user.active.file}.log </property> </properties> <appenders> <Console name="Console" target="SYSTEM_OUT"> <ThresholdFilter level="trace" onMatch="ACCEPT" onMismatch="DENY" /> <PatternLayout pattern="%msg%n" /> </Console> <RollingFile name="RollingFile" fileName="${LOG_HOME}/dev_${SERVER_NAME}.log" filePattern="${LOG_HOME}/dev_${BACKUP_HOME}/dev_${SERVER_NAME}.%d{yyyy-MM-dd-HH}.log"> <PatternLayout pattern="%msg%n" /> <Policies> <SizeBasedTriggeringPolicy size="${EVERY_FILE_SIZE}" /> <TimeBasedTriggeringPolicy interval="1" modulate="true" /> </Policies> <Filters> <ThresholdFilter level="error" onMatch="DENY" onMismatch="NEUTRAL" /> <ThresholdFilter level="trace" onMatch="ACCEPT" onMismatch="DENY" /> </Filters> </RollingFile> <!-- 只显示error级别的信息 --> <RollingFile name="RollingFileError" fileName="${LOG_HOME}/dev_${SERVER_NAME}_error.log" filePattern="${LOG_HOME}/dev_${BACKUP_HOME}/dev_${SERVER_NAME}_error.%d{yyyy-MM-dd-HH}.log"> <PatternLayout pattern="%msg%xEx%n" /> <Policies> <SizeBasedTriggeringPolicy size="${EVERY_FILE_SIZE}" /> <TimeBasedTriggeringPolicy interval="1" modulate="true" /> </Policies> <Filters> <ThresholdFilter level="error" onMatch="ACCEPT" onMismatch="DENY" /> </Filters> </RollingFile> <!-- 产品数据分析日志 --> <RollingRandomAccessFile name="ProductLog" fileName="${LOG_HOME}/${SERVER_NAME}.log" filePattern="${LOG_HOME}/${BACKUP_HOME}/${SERVER_NAME}.%d{yyyy-MM-dd-HH}.log"> <PatternLayout pattern="%msg%xEx%n" /> <Policies> <SizeBasedTriggeringPolicy size="${EVERY_FILE_SIZE}" /> <TimeBasedTriggeringPolicy interval="1" modulate="true" /> </Policies> </RollingRandomAccessFile> <!-- 用户行为日志 --> <RollingRandomAccessFile name="UserActiveLog" fileName="${log.user.active.path}" filePattern="${log.user.active.folder}/${BACKUP_HOME}/${log.user.active.file}.%d{yyyy-MM-dd-HH}.log"> <PatternLayout pattern="%msg%xEx%n" /> <Policies> <SizeBasedTriggeringPolicy size="${EVERY_FILE_SIZE}" /> <TimeBasedTriggeringPolicy interval="1" modulate="true" /> </Policies> </RollingRandomAccessFile> </appenders> <loggers> <logger name="org.slf4j" level="INFO" /> <logger name="org.springframework" level="INFO" /> <logger name="org.apache.zookeeper" level="WARN" /> <AsyncLogger name="cn.rebuy" level="${OUTPUT_LOG_LEVEL}" additivity="false" includeLocation="true"> <appender-ref ref="Console" /> <appender-ref ref="ProductLog" /> </AsyncLogger> <asyncRoot level="info" includeLocation="true"> <appender-ref ref="Console" /> <appender-ref ref="RollingFile" /> <appender-ref ref="RollingFileError" /> </asyncRoot> </loggers> </configuration>
2.5、新增spring-mvc.xml文件
<?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" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.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="cn.com.controller" > <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/> </context:component-scan> <mvc:annotation-driven > <mvc:message-converters> <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> <value>application/json;charset=UTF-8</value> <value>application/x-www-form-urlencoded;charset=UTF-8</value> </list> </property> </bean> </mvc:message-converters> </mvc:annotation-driven> </beans>
2.6、在src/main/webapp/WEB-INF目录下修改web.xml配置文件：
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1"> <display-name>longTest</display-name> <!-- 配置加载Spring文件的监听器--> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mybatis.xml</param-value> </context-param> <!-- 编码过滤器 --> <filter> <filter-name>encoding</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encoding</filter-name> <url-pattern>*.action</url-pattern> </filter-mapping> <!-- 防止Spring内存溢出监听器 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 配置Spring MVC前端核心控制器 --> <servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <!-- 配置服务器启动后立即加载Spring MVC配置文件 --> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
3、新建数据库，配置好数据库的连接，新建表结构
4、建好src/main/java文件夹下存放文件的包路径，然后分层结构，实体类、数据访问层、用户界面交互层，可以利用（MyBatis Generator自动创建）
5、然后将开发完的项目部署到本地tomcat服务器上，然后启动tomcat，输入本地地址加端口的形式进行验证测试。
不忘初心，相信自己，坚持下去，付诸实施。
