主角即Spring、SpringMVC、MyBatis、easyUI,大家应该也都有所了解,概念性的东西就不写了,有万能的百度。
工作环境:
jdk 1.7
mysql 5.6
IntelliJ IDEA 15
tomcat 7
以上为本地的构建环境,当然,如果开发环境版本或者ide与以上不同也是可以正常搭建环境的,比如你jdk是1.8啊,ide用的是eclipse或者myeclipse都是完全OK的。
整合步骤:
以下为项目的目录结构,
entity包中即为本项目的所有实体类,dao包中为数据层接口,mappers中为数据层接口的sql映射文件,运行的sql语句是在这些文件中定义的,admin包中则是控制器,以上包名都可以按照个人习惯来命名,WebRoot中则是jsp文件及jar包等文件。
首先第一步,新建一个javaWeb项目,接下来在src目录下entity包、mappers包、dao包和service包,并新增配置Spring的文件applicationContext.xml和mybatis的配置文件mybatis-config.xml。
1、applicationContext.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:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd"> <!-- 自动扫描dao层和service层,将包中的类纳入到Spring的管理中 --> <context:component-scan base-package="com.core.dao"/> <context:component-scan base-package="com.core.service"/> <!-- 配置数据源 --> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"/> <property name=“url" value="jdbc:mysql://xx.xx.xx.xx:xx/db"/> <!-- 改为你的地址即可 --> <property name="username" value="xxxx"/> <property name="password" value="xxxx"/> </bean> <!-- 配置mybatis的sqlSessionFactory --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <!-- 自动扫描mappers包下的所有xml文件 --> <property name="mapperLocations" value="classpath:com/core/mappers/*.xml"></property> <!-- mybatis配置文件 --> <property name="configLocation" value="classpath:mybatis-config.xml"></property> </bean> <!-- dao接口所在包名,Spring会自动查找其下的类 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.core.dao"/> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property> </bean> <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"/> </bean> <!-- 配置事务通知属性 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <!-- 定义事务传播属性 --> <tx:attributes> <tx:method name="insert*" propagation="REQUIRED"/> <tx:method name="update*" propagation="REQUIRED"/> <tx:method name="upd*" propagation="REQUIRED"/> <tx:method name="edit*" propagation="REQUIRED"/> <tx:method name="save*" propagation="REQUIRED"/> <tx:method name="add*" propagation="REQUIRED"/> <tx:method name="new*" propagation="REQUIRED"/> <tx:method name="set*" propagation="REQUIRED"/> <tx:method name="remove*" propagation="REQUIRED"/> <tx:method name="delete*" propagation="REQUIRED"/> <tx:method name="del*" propagation="REQUIRED"/> <tx:method name="change*" propagation="REQUIRED"/> <tx:method name="check*" propagation="REQUIRED"/> <tx:method name="get*" propagation="REQUIRED" read-only="true"/> <tx:method name="search*" propagation="REQUIRED" read-only="true"/> <tx:method name="find*" propagation="REQUIRED" read-only="true"/> <tx:method name="load*" propagation="REQUIRED" read-only="true"/> <tx:method name="*" propagation="REQUIRED" read-only="true"/> </tx:attributes> </tx:advice> <!-- 配置事务切面,service包中的类会被代理 --> <aop:config> <aop:pointcut id="serviceOperation" expression="(execution(* com.core.service.*.*(..)))"/> <aop:advisor advice-ref="txAdvice" pointcut-ref="serviceOperation"/> </aop:config> </beans>
2、mybatis-config.xml
<?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> <setting name="logImpl" value="LOG4J"/> </settings> <typeAliases> <package name="com.core.entity"/> </typeAliases> </configuration>
3、接着是SpringMVC的配置文件:
<?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:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"> <!-- 扫描admin包,将控制器纳入Spring的管理中 --> <context:component-scan base-package="com.core.admin"/> <!-- 视图解析器,视图模式下的前缀和后缀 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value=“/“/> <property name="suffix" value=".jsp"></property> </bean> </beans>
4、web.xml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" 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>ssm-demo</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> </welcome-file-list> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <filter> <filter-name>encodingFilter</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>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- spring请求配置,指向springmvc的核心配置文件,定义所有以.do结尾的请求都被springmvc拦截 --> <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> <!--加载顺序为1 --> <load-on-startup>1</load-on-startup> </servlet> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <!— 错误页面配置,这里只是简单的配置了一下 --> <error-page> <error-code>404</error-code> <location>/main.jsp</location> </error-page> <error-page> <error-code>500</error-code> <location>/main.jsp</location> </error-page> </web-app>
整合过程中需要注意的点:
项目编码设置正确,jar包要齐全,mysql要能正常登录。
当然,也可以直接导入源码,
