一、springmvc---controller spring----service mybatiss---dao
pring（包括springmvc）、mybatis、mybatis-spring整合包、数据库驱动、第三方连接池。
因为springmvc和spring属于同一个公司不需要整合包，而mybaits和spring需要整合包。
二、jar包列表
pom文件依赖：

三、配置文件
1、SqlMapConfig.xml： mybaits配置文件，只保存约束和configuration标签即可，其中的mapper映射在applicationContex-dao.xml里进行添加。
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE configuration 3 PUBLIC "-//mybatis.org//DTD Config 3.0//EN" 4 "http://mybatis.org/dtd/mybatis-3-config.dtd"> 5 6 7 <configuration> 8 </configuration>
2、applicationContext-dao.xml：dao层配置文件 (注解扫描在其他文件配置即可)
1）数据库连接池
2）会话工厂
3）配置mapper扫描
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:context="http://www.springframework.org/schema/context" 4 xmlns:p="http://www.springframework.org/schema/p" 5 xmlns:aop="http://www.springframework.org/schema/aop" 6 xmlns:tx="http://www.springframework.org/schema/tx" 7 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 8 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd 9 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd 10 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd 11 http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> 12 13 <!-- 加载配置文件 --> 14 <context:property-placeholder location="classpath:db.properties"/> 15 <!-- 数据库连接池 --> 16 <bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close"> 17 <property name="driverClassName" value="${jdbc.driver}"/> 18 <property name="url" value="${jdbc.url}"/> 19 <property name="username" value="${jdbc.username}"/> 20 <property name="password" value="${jdbc.password}"/> 21 <property name="maxTotal" value="10"/> 22 <property name="maxIdle" value="5"/> 23 </bean> 24 <!-- mapper配置 --> 25 <!-- 让spring管理sqlsessionfactory 使用mybatis和spring整合包中的 --> 26 <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> 27 <!-- 数据库连接池 --> 28 <property name="dataSource" ref="dataSource"/> 29 <!-- 加载mybatis的全局配置文件 --> 30 <property name="configLocation" value="classpath:SqlMapConfig.xml"/> 31 </bean> 32 <!-- 配置Mapper扫描器 --> 33 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> 34 <property name="basePackage" value="jd.com.dao"/> 35 </bean> 36 </beans>
3、service层
1）applicationContext-service.xml 包扫描器和Service层的注解开启。
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:context="http://www.springframework.org/schema/context" 4 xmlns:p="http://www.springframework.org/schema/p" 5 xmlns:aop="http://www.springframework.org/schema/aop" 6 xmlns:tx="http://www.springframework.org/schema/tx" 7 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 8 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd 9 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd 10 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd 11 http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> 12 <!--开启注解扫描--> 13 <context:component-scan base-package="jd.com" /> 14 15 </beans>
2）applicationContext-trans.xml事务配置文件。
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:context="http://www.springframework.org/schema/context" 4 xmlns:p="http://www.springframework.org/schema/p" 5 xmlns:aop="http://www.springframework.org/schema/aop" 6 xmlns:tx="http://www.springframework.org/schema/tx" 7 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 8 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd 9 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd 10 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd 11 http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> 12 13 <!-- 事务管理器 --> 14 <bean id="transactionManager" 15 class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> 16 <!-- 数据源 --> 17 <property name="dataSource" ref="dataSource"/> 18 </bean> 19 <!-- 通知 --> 20 <tx:advice id="txAdvice" transaction-manager="transactionManager"> 21 <tx:attributes> 22 <!-- 传播行为 --> 23 <tx:method name="save*" propagation="REQUIRED"/> 24 <tx:method name="insert*" propagation="REQUIRED"/> 25 <tx:method name="delete*" propagation="REQUIRED"/> 26 <tx:method name="update*" propagation="REQUIRED"/> 27 <tx:method name="find*" propagation="SUPPORTS" read-only="true"/> 28 <tx:method name="get*" propagation="SUPPORTS" read-only="true"/> 29 </tx:attributes> 30 </tx:advice> 31 <!-- 切面 --> 32 <aop:config> 33 <aop:advisor advice-ref="txAdvice" 34 pointcut="execution(* jd.com.service.*.*(..))"/> 35 </aop:config> 36 37 </beans>
4、Springmvc.xml
1）注解扫描器开启
2）注解驱动（处理器映射器和处理器适配器）
3)视图解析器配置
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:p="http://www.springframework.org/schema/p" 5 xmlns:context="http://www.springframework.org/schema/context" 6 xmlns:mvc="http://www.springframework.org/schema/mvc" 7 xsi:schemaLocation="http://www.springframework.org/schema/beans 8 http://www.springframework.org/schema/beans/spring-beans-4.0.xsd 9 http://www.springframework.org/schema/mvc 10 http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd 11 http://www.springframework.org/schema/context 12 http://www.springframework.org/schema/context/spring-context-4.0.xsd"> 13 <!--开启注解扫描--> 14 <context:component-scan base-package="jd.com.contronller"/> 15 <!--开启注解驱动--> 16 <mvc:annotation-driven/> 17 <!--视图解析器配置--> 18 <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" > 19 <property name="prefix" value="WEB-INF/jsp/"/> 20 <property name="suffix" value=".jsp" /> 21 <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> 22 </bean> 23 24 25 </beans>
注意上面配置的视图解析器有问题。前缀必须要/否则在配置窄化请求映射的时候会报如下错误：
正确配置：
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:p="http://www.springframework.org/schema/p" 5 xmlns:context="http://www.springframework.org/schema/context" 6 xmlns:mvc="http://www.springframework.org/schema/mvc" 7 xsi:schemaLocation="http://www.springframework.org/schema/beans 8 http://www.springframework.org/schema/beans/spring-beans-4.0.xsd 9 http://www.springframework.org/schema/mvc 10 http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd 11 http://www.springframework.org/schema/context 12 http://www.springframework.org/schema/context/spring-context-4.0.xsd"> 13 <!--开启注解扫描--> 14 <context:component-scan base-package="jd.com.contronller"/> 15 <!--开启注解驱动--> 16 <mvc:annotation-driven conversion-service="conversionService" /> 17 <!--视图解析器配置--> 18 <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" > 19 <property name="prefix" value="/WEB-INF/jsp/"/> 20 <property name="suffix" value=".jsp" /> 21 <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> 22 </bean> 23 <mvc:resources mapping="/resource/**" location="/resources/"/> 24 25 <!--自定义转换器 注意在注解驱动里指明引用--> 26 <bean id="conversionService" 27 class="org.springframework.format.support.FormattingConversionServiceFactoryBean"> 28 <property name="converters"> 29 <set> 30 <bean class="jd.com.contronller.jd.com.convert.CustomStringToDate"/> 31 </set> 32 </property> 33 </bean> 34 35 </beans>
5、web.xml 前端控制器配置。
1 <!DOCTYPE web-app PUBLIC 2 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" 3 "http://java.sun.com/dtd/web-app_2_3.dtd" > 4 5 <web-app> 6 7 8 <!-- 加载spring容器 --> 9 <context-param> 10 <param-name>contextConfigLocation</param-name> 11 <param-value>classpath:applicationContext-*.xml</param-value> 12 </context-param> 13 <listener> 14 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 15 </listener> 16 <servlet> 17 <servlet-name>springmvc</servlet-name> 18 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 19 <init-param> 20 <param-name>contextConfigLocation</param-name> 21 <!--使用通配符加载所有的配置文件--> 22 <param-value>classpath:springmvc.xml</param-value> 23 </init-param> 24 <load-on-startup>1</load-on-startup> 25 </servlet> 26 <servlet-mapping> 27 <servlet-name>springmvc</servlet-name> 28 <url-pattern>*.action</url-pattern> 29 </servlet-mapping> 30 </web-app>
建表和插入数据
1 CREATE TABLE goods( 2 id INT AUTO_INCREMENT, 3 goodsname VARCHAR(20), 4 money DOUBLE, 5 detail VARCHAR(100), 6 PRIMARY KEY(id) 7 );
mapper文件：
接口：
1 package jd.com.dao; 2 3 import java.util.List; 4 import jd.com.projo.goods; 5 6 public interface goodsMapperImpl { 7 List<goods> findGoodsById(); 8 }
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE mapper 3 PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" 4 "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> 5 <!--和主配置文件约束是不一样的--> 6 7 <mapper namespace="jd.com.dao.goodsMapperImpl"> 8 <select id="findGoodsById" resultType="jd.com.projo.goods" > 9 select * from goods 10 </select> 11 </mapper>
