SpringMVC+Mybatis整合搭建

1.使用eclipse构建SpringMVC工程

    1.构建过程可参考eclipse构建ｓｐｒｉｎｇｍｖｃ

２．开始配置工程项目

    2.1.构建好的工程结构如下：

   2.2.使用maven管理项目，添加项目所依赖的jar包

2.3.配置web.xml

<?xml version="1.0" encoding="UTF-8"?>  <web-app xmlns="http://java.sun.com/xml/ns/javaee"            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"           xsi:schemaLocation="http://java.sun.com/xml/ns/javaee                                http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"            version="2.5" >    <display-name>bobo.smvc.example</display-name>   <!-- 区分项目名称，防止默认重名 -->     <context-param>     <param-name>webAppRootKey</param-name>     <param-value>bobo.smvc.example</param-value>   </context-param>   <!-- Spring监听器  --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener>      <!-- Spring的log4j监听器 -->     <listener>     <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>   </listener>      <!-- 字符集 过滤器  -->     <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>     <init-param>        <param-name>forceEncoding</param-name>        <param-value>true</param-value>     </init-param>   </filter>   <filter-mapping>      <filter-name>CharacterEncodingFilter</filter-name>      <url-pattern>/*</url-pattern>   </filter-mapping>      <!-- Spring上下文配置 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:/spring/applicationContext.xml</param-value></context-param>       <!-- Spring view分发器 -->      <servlet>       <servlet-name>dispatcher</servlet-name>       <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>       <init-param>         <param-name>contextConfigLocation</param-name>         <param-value>classpath:/spring/dispatcher-servlet.xml</param-value>       </init-param>       <load-on-startup>1</load-on-startup>    </servlet>    <servlet-mapping>        <servlet-name>dispatcher</servlet-name>        <url-pattern>*.do</url-pattern>    </servlet-mapping>      <!-- 配置session存在时间 -->  <session-config>    <session-timeout>60</session-timeout>  </session-config>     <!-- Log4J 配置  --><context-param><param-name>log4jConfigLocation</param-name>    <param-value>classpath:log4j.properties</param-value></context-param>       <!-- 默认起始页面 -->   <welcome-file-list>    <welcome-file>index.jsp</welcome-file>   </welcome-file-list>      <!-- 异常跳转页面 -->   <error-page>        <exception-type>java.lang.Exception</exception-type>        <location>/WEB-INF/views/exception.jsp</location>   </error-page></web-app>

  2.4.配置applicationContext.xml (这里只导入了另一个xml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:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="        http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans-3.1.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context-3.1.xsd        http://www.springframework.org/schema/aop         http://www.springframework.org/schema/aop/spring-aop-3.1.xsd           http://www.springframework.org/schema/tx          http://www.springframework.org/schema/tx/spring-tx-3.1.xsd ">     <!-- 导入分割的spring配置文件 --><import resource="applicationContext-datasource.xml"/></beans>

  2.5.配置dispatcher-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>  <beans xmlns="http://www.springframework.org/schema/beans"              xmlns:aop="http://www.springframework.org/schema/aop"              xmlns:context="http://www.springframework.org/schema/context"             xmlns:mvc="http://www.springframework.org/schema/mvc"              xmlns:tx="http://www.springframework.org/schema/tx"              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"             xsi:schemaLocation="http://www.springframework.org/schema/aop               http://www.springframework.org/schema/aop/spring-aop-3.0.xsd               http://www.springframework.org/schema/beans               http://www.springframework.org/schema/beans/spring-beans-3.0.xsd               http://www.springframework.org/schema/context               http://www.springframework.org/schema/context/spring-context-3.0.xsd               http://www.springframework.org/schema/mvc               http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd               http://www.springframework.org/schema/tx               http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">                <!-- 启用spring mvc 注解-->        <mvc:annotation-driven />                  <!-- 自动扫描的包名 ，使Spring支持自动检测组件，如注解的Controller-->          <context:component-scan base-package="com.bobo.controller" />        <!-- 自动扫描的包名 ，使Spring支持自动检测组件，如注解的Service (在service的实现类上加@service时用)-->         <context:component-scan base-package="com.bobo.service" />                <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">              <property name="prefix" value="/WEB-INF/views/" />              <property name="suffix" value=".jsp" />          </bean>        </beans>

  2.6.配置applicationContext-datasource.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:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="        http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans-3.1.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context-3.1.xsd        http://www.springframework.org/schema/aop         http://www.springframework.org/schema/aop/spring-aop-3.1.xsd           http://www.springframework.org/schema/tx          http://www.springframework.org/schema/tx/spring-tx-3.1.xsd "><!-- <import resource="classpath:spring/datasource/detail3ydb.xml" /> --> <tx:annotation-driven transaction-manager="txManager" />    <!-- spring管理事务 --><bean id="txManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource" /></bean><!-- 配置sqlSessionFactory --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean" ><property name="dataSource" ref="dataSource" /><property name="mapperLocations"><list><value>classpath:mybatis/mapper/*Mapper.xml</value></list></property></bean><!-- 设置与事务有关的各种属性  --><!--  <tx:advice id="txAdvice" transaction-manager="txManager"><tx:attributes><tx:method name="insert*"  propagation="REQUIRED" rollback-for="Exception"/><tx:method name="add*" propagation="REQUIRED" rollback-for="Exception" /><tx:method name="update*" propagation="REQUIRED" rollback-for="Exception" /><tx:method name="del*" propagation="REQUIRED" rollback-for="Exception" /><tx:method name="save*" propagation="REQUIRED" rollback-for="Exception" /><tx:method name="remove*" propagation="REQUIRED" rollback-for="Exception" /><tx:method name="select*"  propagation="SUPPORTS"/><tx:method name="get*"  propagation="SUPPORTS"/><tx:method name="find*"  propagation="SUPPORTS"/><tx:method name="query*"  propagation="SUPPORTS"/><tx:method name="*" propagation="SUPPORTS" /></tx:attributes></tx:advice> --> <!-- 声明切入点 --><!-- <aop:config ><aop:pointcut id="loginPointCuts"expression="execution(* com.hc360.detail.sitemap.service..*.*(..))" /><aop:advisor advice-ref="txAdvice" pointcut-ref="loginPointCuts" /></aop:config> --><!-- 通过扫描的模式,自动注入bean -->    <bean name="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value="com.bobo.dao" /><property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property></bean>    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">        <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />        <property name="ignoreResourceNotFound" value="true" />        <property name="locations">            <list>                <!-- standard config -->                <value>classpath:jdbc.properties</value>            </list>        </property>    </bean> <!--   <context:property-placeholder location="classpath:jdbc.properties" ignore-unresolvable="true"/> --><bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">  <property name="driverClassName" value="${jdbc.driverClassName}" /><property name="url" value="${jdbc.url}" /><property name="username" value="${jdbc.username}" /><property name="password" value="${jdbc.password}" /><property name="maxActive" value="${jdbc.maxActive}" /><property name="maxIdle" value="${jdbc.maxIdle}" /><property name="maxWait" value="${jdbc.maxWait}" /></bean> </beans>

  2.7.配置controller

package com.bobo.controller;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;import com.bobo.service.OnCorTableService;@Controller//@RequestMapping("/thello")public class Hello {Logger loger= LoggerFactory.getLogger(Hello.class);@Autowired(required=true)OnCorTableService oncortableservice;@RequestMapping(value="/he/thell0.do")public String tHello(HttpServletRequest request,HttpServletResponse response,Model model){model.addAttribute("hello", "Hello,mvc");//System.out.println("hello.jsp");Long ucount= oncortableservice.getuserCount();//查询用户数量model.addAttribute("ucount", ucount+"");loger.info("用户人数："+ucount);System.out.println("用户人数："+ucount);return "hello";}}

   2.8.配置service（OnCorTableService和实现类OnCorTableServiceImpl）

package com.bobo.service;public interface OnCorTableService {public long getuserCount();}

package com.bobo.service.impl;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import com.bobo.dao.OnCorTableMapper;import com.bobo.service.OnCorTableService;@Servicepublic class OnCorTableImpl implements OnCorTableService{@Autowired(required=true)OnCorTableMapper oncortablemapper;@Overridepublic long getuserCount() {// TODO Auto-generated method stubreturn oncortablemapper.getUsernameCount();}}

   2.9.配置dao（OnCorTableMapper.java和OnCorTableMapper.xml）

package com.bobo.dao;public interface OnCorTableMapper{/** * 查询用户名个数* @author hc360* @version 1.0* @date 2014-11-10* @param * @return Long */Long getUsernameCount();/** * 查询  增量 用户名个数* @author hc360* @version 1.0* @date 2014-11-10* @param * @return Long */Long getIncreaceUsernameCount(long turnStartId);Long getLastProviderIdByUsername(String username);}

<?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" ><mapper namespace="com.bobo.dao.OnCorTableMapper"><select id="getUsernameCount" resultType="java.lang.Long">SELECT count(t.USERNAME) FROM on_cor_table t</select><select id="getIncreaceUsernameCount" resultType="java.lang.Long">SELECT count(t.USERNAME) FROM on_cor_table t where t.providerid >#{turnstartId}</select><select id="getLastProviderIdByUsername" resultType="java.lang.Long" parameterType="String">SELECT t.providerid FROM on_cor_table t where t.USERNAME=#{username} </select></mapper>

2.10.配置jdbc.properties

jdbc.driverClassName=oracle.jdbc.driver.OracleDriverjdbc.url=jdbc:oracle:thin:@100.000.00.000:1521:bjdt4jdbc.username=newhcjdbc.password=bfdds06fdjdbc.maxActive=20jdbc.maxIdle=50jdbc.maxWait=10000jdbc0.url=jdbc:oracle:thin:@100.000.00.000:1521:bjdt4jdbc0.username=newhcjdbc0.password=bfdds06fd

2.11.配置log4j.properties

log4j.rootLogger=debug,console,filelog### 输出信息到控制台###log4j.appender.console=org.apache.log4j.ConsoleAppenderlog4j.appender.console.layout=org.apache.log4j.PatternLayoutlog4j.appender.console.layout.ConversionPattern=[%d] [%t] (%F:%L) %-5p %c - %m%nlog4j.appender.console.Encoding=GB18030### 输出DEBUG 级别以上的日志到=/smvc/logs/all/smvc.log ###log4j.appender.filelog = org.apache.log4j.DailyRollingFileAppenderlog4j.appender.filelog.File = /smvc/logs/all/smvc.loglog4j.appender.filelog.Encoding=GB18030log4j.appender.filelog.layout = org.apache.log4j.PatternLayoutlog4j.appender.filelog.DatePattern = '.'yyyy-MM-dd-HHlog4j.appender.filelog.layout.ConversionPattern =[%d] [%t] (%F:%L) %-5p %c - %m%nlog4j.appender.filelog.Threshold=DEBUG

到此为止一个简单的SpringMVC+Mybatis整合就完成了。。。。后续就是加入你自己的业务逻辑代码了~
