点这里看实际效果! 账密:admin 123456
框架介绍:
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, 点击这里下载代码

springmvc配置文件中没有配置处理器映射器和处理器适配器,是不是忘记了呢?
灰常谢谢你的分享,加油。
数据库在哪里?请教一下
