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, 图片描述

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 github地址在这里
