1.创建maven web 项目
maven 创建web应用命令：
mvn archetype:generate -DgroupId=[com.rom]包名 -DartifactId=[cpsrom]项目名 -DarchetypeArtifactId=maven-archetype-webapp;
2.pom.xml 导入相关依赖包
<dependencies> <!-- spring核心包 --> <!-- springframe start --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-oxm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <!-- springframe end --> <!-- http://mvnrepository.com/artifact/commons-fileupload/commons-fileupload --> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.1</version> </dependency> <!-- mybatis核心包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatis/spring包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.2</version> </dependency> <!-- mysql驱动包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.29</version> </dependency> <!-- junit测试包 --> <!-- http://mvnrepository.com/artifact/c3p0/c3p0 --> <dependency> <groupId>c3p0</groupId> <artifactId>c3p0</artifactId> <version>0.9.1.2</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> </dependencies>
3. 创建spring.xml 配置文件
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:util="http://www.springframework.org/schema/util" 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.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-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/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd"> <!-- 引入jdbc配置文件 --> <context:property-placeholder location="classpath:system.properties"/> <!-- 扫描文件（自动将servicec层注入） --> <context:component-scan base-package="com.cater.rom"/> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close" > <property name="driverClass" value="${jdbc.driverClass}" /> <property name="jdbcUrl" value="${jdbc.jdbcUrl}" /> <property name="user" value="${jdbc.user}" /> <property name="password" value="${jdbc.password}" /> <property name="maxPoolSize" value="${jdbc.maxPoolSize}" /> <property name="minPoolSize" value="${jdbc.minPoolSize}" /> <property name="initialPoolSize" value="${jdbc.initialPoolSize}" /> <property name="maxIdleTime" value="${jdbc.maxIdleTime}" /> </bean> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="maxUploadSize" value="1073741824" /> </bean> <!-- 避免IE在ajax请求时，返回json出现下载 --> <!-- <bean id="jacksonMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> </list> </property> </bean> --> <!-- mybatis文件配置，扫描所有mapper文件 <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean" p:dataSource-ref="dataSource" p:configLocation="classpath:mybatis-config.xml" />--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <property name="configLocation" value="classpath:mybatis-config.xml"></property> </bean> <!-- configLocation为mybatis属性 mapperLocations为所有mapper--> <!-- p:mapperLocations="classpath:mapper/*.xml" --> <!-- spring与mybatis整合配置，扫描所有dao --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" p:basePackage="com.cater.rom" p:sqlSessionFactoryBeanName="sqlSessionFactory"/> <!-- 对数据源进行事务管理 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager" p:dataSource-ref="dataSource"/> <!-- 对模型视图添加前后缀 --> <!-- <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/view/" p:suffix=".jsp"/>--> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- <property name="viewClass"> <value>org.springframework.web.servlet.view.JstlView</value> </property> --> <property name="prefix" value="/"/> <property name="suffix" value=".jsp"/> </bean> </beans>
4.创建mybatis.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> <!-- 命名空间 --> <typeAliases>
<typeAlias alias="pmChannel" type="com.cater.rom.entity.PmChannel"/> </typeAliases> <!-- 映射map --> <mappers> <mapper resource="com/cater/rom/entity/PmChannelMapper.xml"/> </mappers> </configuration>
5.配置数据连接信息system.properties
#数据库连接 jdbc.jdbcUrl=jdbc:mysql://数据库ip地址:数据库端口号/数据库名称?autoReconnect=true&autoReconnectForPools=true jdbc.driverClass=com.mysql.jdbc.Driver jdbc.user=用户名 jdbc.password=连接密码 jdbc.maxPoolSize= 40 jdbc.minPoolSize= 1 jdbc.initialPoolSize= 1 jdbc.maxIdleTime=20
6、更改web.xml 配置文件
<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 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>Archetype Created Web Application</display-name> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 读取spring配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring.xml</param-value> </context-param> <!-- 设计路径变量值 --> <context-param> <param-name>webAppRootKey</param-name> <param-value>app.cater</param-value> </context-param> <!-- springMVC核心配置 --> <servlet> <servlet-name>spring</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>*.html</url-pattern> </servlet-mapping> <!-- Spring字符集过滤器 --> <filter> <filter-name>SpringEncodingFilter</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> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>SpringEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
7. 创建实体类配置文件
<?xml version="1.0" encoding="utf-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <!-- 指定要实现dao的全路径 方法名与id一致 --> <mapper namespace="com.cater.rom.channel.dao.ChannelDao"> <resultMap type="com.cater.rom.entity.PmChannel" id="pmChannel"> <id column="id" property="id" /> <result column="name" property="name" /> <result column="password" property="password" /> <result column="contact_name" property="contactName" /> <result column="contact_phone" property="contactPhone" /> <result column="parent_name" property="parentName" /> <result column="status" property="status" /> <result column="roleid" property="roleid" /> <result column="grade" property="grade" /> </resultMap> <!-- 登录 id与dao 中的方法一致 --> <select id="login"></select> </mapper>
