一. 创建数据库和表
二. 逆向生成接口类和映射文件
1、在工作空间导入generatorSqlmapCustom逆向工程
2、修改generatorConfig.xml配置:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"> <generatorConfiguration> <context id="testTables" targetRuntime="MyBatis3"> <commentGenerator> <!-- 是否去除自动生成的注释 true:是 : false:否 --> <property name="suppressAllComments" value="true" /> </commentGenerator> <!--数据库连接的信息:驱动类、连接地址、用户名、密码 --> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://192.168.159.130:3306/e3mall-32" userId="root" password="root1"> </jdbcConnection> <!-- 默认false,把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer,为 true时把JDBC DECIMAL 和 NUMERIC 类型解析为java.math.BigDecimal --> <javaTypeResolver> <property name="forceBigDecimals" value="false" /> </javaTypeResolver> <!-- targetProject:生成PO类的位置 --> <javaModelGenerator targetPackage="cn.e3mall.pojo" targetProject=".src"> <!-- enableSubPackages:是否让schema作为包的后缀 --> <property name="enableSubPackages" value="false" /> <!-- 从数据库返回的值被清理前后的空格 --> <property name="trimStrings" value="true" /> </javaModelGenerator> <!-- targetProject:mapper映射文件生成的位置 --> <sqlMapGenerator targetPackage="cn.e3mall.mapper" targetProject=".src"> <!-- enableSubPackages:是否让schema作为包的后缀 --> <property name="enableSubPackages" value="false" /> </sqlMapGenerator> <!-- targetPackage:mapper接口生成的位置 --> <javaClientGenerator type="XMLMAPPER" targetPackage="cn.e3mall.mapper" targetProject=".src"> <!-- enableSubPackages:是否让schema作为包的后缀 --> <property name="enableSubPackages" value="false" /> </javaClientGenerator> <!-- 指定数据库表 --> <table schema="" tableName="tb_content"></table> <table schema="" tableName="tb_content_category"></table> <table schema="" tableName="tb_item"></table> <table schema="" tableName="tb_item_cat"></table> <table schema="" tableName="tb_item_desc"></table> <table schema="" tableName="tb_item_param"></table> <table schema="" tableName="tb_item_param_item"></table> <table schema="" tableName="tb_order"></table> <table schema="" tableName="tb_order_item"></table> <table schema="" tableName="tb_order_shipping"></table> <table schema="" tableName="tb_user"></table> </context> </generatorConfiguration>
3、运行逆向工程main方法并刷新工程下src目录,将生成的mapper和pojo分别粘贴至e3-manage-dao和e3-manage-pojo里
注意:建议将mapper映射文件和接口分别放入resource和java目录中,若将二者都放入java里,需要在e3-manager-dao工程的pom里配置:
<!-- 如果不添加此节点mybatis的mapper.xml文件都会被漏掉。 --> <build> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> </includes> <filtering>false</filtering> </resource> </resources> </build>
三. 整合Dao(先把该导入的约束导入到workspace,整合配置文件统一放到e3manager-web的resource目录)
1、创建SqlMapConfig.xml(只需要一个文件头):
<?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> </configuration>
2、Spring整合Mybatis,创建applicationContext-dao.xml:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 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/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-4.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd"> <!-- 数据库连接池 --> <!-- 加载配置文件 --> <context:property-placeholder location="classpath:conf/db.properties" /> <!-- 数据库连接池 --> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close"> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <property name="driverClassName" value="${jdbc.driver}" /> <property name="maxActive" value="10" /> <property name="minIdle" value="5" /> </bean> <!-- 让spring管理sqlsessionfactory使用mybatis和spring整合包中的 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 数据库连接池 --> <property name="dataSource" ref="dataSource" /> <!-- 加载mybatis的全局配置文件 --> <property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml" /> </bean> <!-- 将mapper接口注册到spring容器 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="cn.e3mall.mapper" /> </bean> </beans>
3、创建db.properties:
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/e3mall?characterEncoding=utf-8
jdbc.username=root
jdbc.password=root1
四. 整合Service
1、配置包扫描器,创建applicationContext-service.xml:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 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/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd"> <context:component-scan base-package="cn.e3mall.service"/> </beans>
2、管理事务,创建applicationContext-trans.xml:
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 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/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd"> <!-- 事务管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!-- 数据源 --> <property name="dataSource" ref="dataSource" /> </bean> <!-- 通知 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <!-- 传播行为 --> <tx:method name="save*" propagation="REQUIRED" /> <tx:method name="insert*" propagation="REQUIRED" /> <tx:method name="add*" propagation="REQUIRED" /> <tx:method name="create*" propagation="REQUIRED" /> <tx:method name="delete*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="find*" propagation="SUPPORTS" read-only="true" /> <tx:method name="select*" propagation="SUPPORTS" read-only="true" /> <tx:method name="get*" propagation="SUPPORTS" read-only="true" /> </tx:attributes> </tx:advice> <!-- 切面 --> <aop:config> <aop:advisor advice-ref="txAdvice" pointcut="execution(* cn.e3mall.service..*.*(..))" /> </aop:config> </beans>
五. 整合表现层
1、创建springmvc.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: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-4.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd"> <!-- 配扫描带有Controller注解的类 --> <context:component-scan base-package="cn.e3mall.controller" /> <!-- 配置处理器映射器和处理器适配器 --> <mvc:annotation-driven /> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> </beans>
2、配置web.xml:
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>e3-manager</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- 加载spring容器 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/applicationContext-*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 解决post乱码 --> <filter> <filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- springmvc的前端控制器 --> <servlet> <servlet-name>e3-manager</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- contextConfigLocation不是必须的, 如果不配置contextConfigLocation, springmvc的配置文件默认在:WEB-INF/servlet的name+"-servlet.xml" --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/springmvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>e3-manager</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
六. 整合测试
1、商品管理Service实现类:
@Service publicclass ItemServiceImpl implements ItemService { @Autowired private TbItemMapper itemMapper; @Override public TbItem getItemById(longid) { TbItem item = itemMapper.selectByPrimaryKey(id); returnitem; } }
2、商品管理Controller:
@Controller publicclass ItemController { @Autowired private ItemService itemService; @RequestMapping("/item/{itemId}") @ResponseBody private TbItem getItemById(@PathVariable Long itemId) { TbItem tbItem = itemService.getItemById(itemId); returntbItem; } }
3、访问http://localhost:8080/item/860275,得到响应:
测试成功!
