第一步
準備環境：idea，maven，jdk，tomcat，mysql，oracle
以上軟件的安裝配置不再贅述。
第二步
創建項目，添加maven管理jar包
引入jar包到pom文件
由於oralce連接數據庫的驅動jar包maven沒有，需要手動引入
pom文件的jar：
<!-- https://mvnrepository.com/artifact/org.aspectj/aspectjweaver --> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.9.2</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>5.0.8.RELEASE</version> </dependency> <!-- https://mvnrepository.com/artifact/org.aspectj/aspectjrt --> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjrt</artifactId> <version>1.9.2</version> </dependency> <!-- https://mvnrepository.com/artifact/aopalliance/aopalliance --> <dependency> <groupId>aopalliance</groupId> <artifactId>aopalliance</artifactId> <version>1.0</version> </dependency> <!-- https://mvnrepository.com/artifact/commons-logging/commons-logging --> <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.2</version> </dependency> <!-- https://mvnrepository.com/artifact/org.apache.commons/commons-dbcp2 --> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.4</version> </dependency> <!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.46</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework/spring-jdbc --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>5.0.8.RELEASE</version> </dependency> <!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-api --> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.25</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.7.12</version> </dependency> <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-core</artifactId> <version>2.10.0</version> </dependency> <!-- https://mvnrepository.com/artifact/com.alibaba/fastjson --> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.47</version> </dependency> <!-- https://mvnrepository.com/artifact/commons-fileupload/commons-fileupload --> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.3</version> </dependency> <!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>com.aliyun</groupId> <artifactId>aliyun-java-sdk-core</artifactId> <version>4.0.6</version> </dependency> <dependency> <groupId>com.aliyun</groupId> <artifactId>aliyun-java-sdk-dysmsapi</artifactId> <version>1.1.0</version> </dependency> <!-- https://mvnrepository.com/artifact/com.oracle/ojdbc6 --> <dependency> <groupId>com.oracle</groupId> <artifactId>ojdbc6</artifactId> <version>11.1.0.6.0</version> <scope>system</scope> <systemPath>${basedir}/web/WEB-INF/lib/ojdbc6-11.1.0.6.0.jar</systemPath> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.4.5</version> </dependency> <!-- https://mvnrepository.com/artifact/org.mybatis/mybatis-spring --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.1</version> </dependency>
第三步
搭建項目框架
（導入web支持，spring支持和mybatis支持會自動導入）
第四步
配置相關配置文件
配置文件：
applicationContent.xml 主配置文件
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!--開啟註解掃描功能--> <context:annotation-config></context:annotation-config> <!--定義註解掃描的包--> <context:component-scan base-package="com.qy.mapper"></context:component-scan> <context:component-scan base-package="com.qy.service"></context:component-scan> <context:component-scan base-package="com.qy.domain"></context:component-scan> <!--開啟aop自動代理模式--> <aop:aspectj-autoproxy proxy-target-class="true"/> <!--從上下文環境中讀取db.properties配置文件--> <context:property-placeholder location="classpath*:db.properties"></context:property-placeholder> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="${oracle.driverClassName}"></property> <property name="url" value="${oracle.url}"></property> <property name="username" value="${oracle.username}"></property> <property name="password" value="${oracle.password}"></property> <property name="maxActive" value="${oracle.maxActive}"></property> <property name="initialSize" value="${oracle.initialSize}"></property> </bean> <!--通過mybatis和spring結合的類，創建sqlsessionFactory--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!--指定myabtis配置文件位置--> <property name="configLocation" value="classpath:mybatis-config.xml" /> </bean> <!-- scan for mappers and let them be autowired MapperScannerConfigurer Mybatis-Spring 會自動為我們註冊Mapper對應的MapperFactoryBean對象--> <!-- Mapper接口所在包名，Spring會自動查找其下的Mapper --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.qy.mapper" /> </bean> <!-- (事務管理)transaction manager, use JtaTransactionManager for global tx --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <!-- 配置事務屬性 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="save*" propagation="REQUIRED"/> <tx:method name="update*" propagation="REQUIRED"/> <tx:method name="delete*" propagation="REQUIRED"/> <tx:method name="*" propagation="NOT_SUPPORTED"></tx:method> </tx:attributes> </tx:advice> <!-- 配置事務切入點 --> <aop:config> <aop:pointcut expression="execution(* com.qy.service.impl.*.*(..))" id="pointCut"/> <aop:advisor advice-ref="txAdvice" pointcut-ref="pointCut"/> </aop:config> </beans>
db.properties 數據庫配置文件
mysql.driverClassName=com.mysql.jdbc.Driver mysql.url=jdbc:mysql://localhost:3306/java1807 mysql.username=root mysql.password=123456 mysql.maxActive=100 mysql.initialSize=5 oracle.driverClassName=oracle.jdbc.OracleDriver oracle.url=jdbc:oracle:thin:@localhost:1521:orcl oracle.username=scott oracle.password=tiger oracle.maxActive=100 oracle.initialSize=5
log4j2.xml 日誌配置文件
（需要在mybatis-config中配置setting）
<!--使用log4j2 配置輸出--> <setting name="logImpl" value="LOG4J2"/>
<?xml version="1.0" encoding="UTF-8"?> <Configuration status="trace"> <Appenders> <Console name="Console" target="SYSTEM_OUT"> <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/> </Console> </Appenders> <Loggers> <Root level="trace"> <AppenderRef ref="Console"/> </Root> <Logger name="com.qy.mapper" level="trace" additivity="false"> <AppenderRef ref="Console"/> </Logger> </Loggers> </Configuration>
mybatis-config.xml 配置文件
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <settings> <!--是否使用緩存 開發中禁用--> <setting name="cacheEnabled" value="false"/> <!--下劃線和駝峰式命名法的匹配 --> <setting name="mapUnderscoreToCamelCase" value="true"/> <!--使用啟用懶加載機制 true啟用--> <setting name="lazyLoadingEnabled" value="true"/> <setting name="multipleResultSetsEnabled" value="true"/> <setting name="useColumnLabel" value="true"/> <setting name="useGeneratedKeys" value="true"/> <setting name="autoMappingBehavior" value="PARTIAL"/> <setting name="autoMappingUnknownColumnBehavior" value="WARNING"/> <setting name="defaultExecutorType" value="SIMPLE"/> <setting name="defaultStatementTimeout" value="25"/> <setting name="defaultFetchSize" value="100"/> <setting name="safeRowBoundsEnabled" value="false"/> <setting name="localCacheScope" value="SESSION"/> <setting name="jdbcTypeForNull" value="OTHER"/> <setting name="lazyLoadTriggerMethods" value="equals,clone,hashCode,toString"/> </settings> <typeAliases> <!--給類起別名--> <!--<typeAlias type="com.qy.domain.Question" alias="Question"></typeAlias>--> <!--給包中所有的類起別名 默認名字為類名 --> <package name="com.qy.domain"></package> </typeAliases> <mappers> <!--引入mapper映射文件的位置--> <!-- <mapper resource="mapper/UserMapper.xml"/> <mapper resource="com/qy/mapper/QuestionMapper.xml"/> <mapper resource="com/qy/mapper/DeptMapper.xml"/> <mapper resource="com/qy/mapper/EmpMapper.xml"/>--> </mappers> </configuration>
springmvc-servlet.xml 配置文件
<?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:mvc="http://www.springframework.org/schema/mvc" 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 http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <!--視圖解析器--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!--指定視圖的前綴和後綴，Controller返回的String類型與這裏的前後綴拼接，構成返回的視圖頁面地址--> <property name="prefix" value="/"/> <property name="suffix" value=".jsp"/> </bean> <!--開啟註解掃描功能--> <mvc:annotation-driven></mvc:annotation-driven> <!-- 處理請求返回json字符串的中文亂碼問題 --> <mvc:annotation-driven> <mvc:message-converters register-defaults="true"> <!-- 解決Controller返回json中文亂碼問題 --> <bean class="org.springframework.http.converter.StringHttpMessageConverter"> <!-- <property name="supportedMediaTypes" value="text/html;charset=UTF-8" /> --> <!-- <property name="supportedMediaTypes" value="application/json;charset=UTF-8" > --> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> <value>application/json;charset=UTF-8</value> </list> </property> </bean> <!-- fastJson配置 --> <bean id="fastJsonHttpMessageConverter" class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/json;charset=UTF-8</value> <value>text/html;charset=UTF-8</value> </list> </property> </bean> </mvc:message-converters> </mvc:annotation-driven> <!--定義註解掃描的包--> <context:component-scan base-package="com.qy.controller"></context:component-scan> <!--處理靜態資源--> <mvc:default-servlet-handler></mvc:default-servlet-handler> <!--將鏈接中的靜態的訪問路徑映射為URL，常用於加載html、js、css、圖片、視頻等靜態資源--> <!-- <mvc:resources mapping="/js/**" location="/background/js/"/> <mvc:resources mapping="/images/**" location="/background/images/"/> <mvc:resources mapping="/css/**" location="/background/css/"/> <mvc:resources mapping="/fonts/**" location="/background/fonts/"/> <mvc:resources mapping="/lib/**" location="/background/lib/"/>--> <!--登錄攔截器--> <!-- <mvc:interceptors> <mvc:interceptor> <!– 攔截所有URL中包含/user/的請求 –> <mvc:mapping path="/**"/> <mvc:exclude-mapping path="/**/fonts/**"/> <mvc:exclude-mapping path="/**/css/**"/> <mvc:exclude-mapping path="/**/js/**"/> <mvc:exclude-mapping path="/**/images/**"/> <mvc:exclude-mapping path="/**/lib/**"/> <mvc:exclude-mapping path="/**/login.html"/> <mvc:exclude-mapping path="/user/toLogin"/> <bean class="com.qy.controller.LoginInterceptor"></bean> </mvc:interceptor> </mvc:interceptors>--> <!--springmvc定義好的，用來處理上傳文件的類--> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 設置上傳文件的最大尺寸為1MB --> <property name="maxUploadSize"> <value>1048576</value> </property> </bean> </beans>
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"> <!--filter 過濾器 用來解決中文亂碼問題--> <filter> <filter-name>characterEncoding</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>characterEncoding</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <servlet> <servlet-name>default1</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc-servlet.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>default1</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!--配置spring--> <!-- 配置去哪裡加載spring的配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- 配置spring的監聽器，加載資源初始化文件 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> </web-app>
第五步
java目錄下的mapper層代替了原來的Dao層（寫接口）
原來dao層實現類變成了resources目錄下相應級目錄的***Mapper.xml
Mapper.xml裏面寫mybatis特有的crue（sql）語句。
