springmvc+spring+mybatis工程搭建

1.新建maven webapp工程，配置pom文件

 1.1添加tomcat插件

<plugins>   <plugin>     <groupId>org.apache.tomcat.maven</groupId>     <artifactId>tomcat7-maven-plugin</artifactId>     <version>2.2</version>     <configuration>       <server>tomcat7</server>       <update>true</update>       <port>8080</port>       <path>/</path>     </configuration>   </plugin> </plugins>

 

 1.2配置文件扫描，将路径中的xml文件，properities文件，ini文件添加到classpath中

<resources>   <resource>     <directory>src/main/java</directory>     <includes>       <include>**/*.xml</include>     </includes>     <filtering>true</filtering>   </resource>   <resource>     <directory>src/main/resources</directory>     <includes>       <include>**/*.properties</include>       <include>**/*.xml</include>       <include>**/*.ini</include>     </includes>     <filtering>false</filtering>   </resource> </resources>

 

2.pom文件添加各个框架所需要的依赖jar包

  2.1添加spring

<dependency>   <groupId>org.springframework</groupId>   <artifactId>spring-context</artifactId>   <version>5.0.8.RELEASE</version> </dependency>

 

  2.2添加spring_webmvc（springmvc）

<!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc --> <dependency>   <groupId>org.springframework</groupId>   <artifactId>spring-webmvc</artifactId>   <version>5.0.8.RELEASE</version> </dependency>

 

  2.3添加mybatis

<dependency>   <groupId>org.mybatis</groupId>   <artifactId>mybatis</artifactId>   <version>3.4.6</version> </dependency>

 

  2.4添加mysql

<dependency>   <groupId>mysql</groupId>   <artifactId>mysql-connector-java</artifactId>   <version>5.1.34</version> </dependency>

 

 

  2.5添加spring_mybatis

<dependency>   <groupId>org.mybatis</groupId>   <artifactId>mybatis-spring</artifactId>   <version>1.3.2</version> </dependency>

 

  2.6添加servlet

<!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api --> <dependency>   <groupId>javax.servlet</groupId>   <artifactId>javax.servlet-api</artifactId>   <version>4.0.1</version>   <scope>provided</scope> </dependency>

 

  

  2.7添加数据库连接池，使用阿里的druid

<dependency>   <groupId>com.alibaba</groupId>   <artifactId>druid</artifactId>   <version>1.1.10</version> </dependency>

 

  2.8添加json，使用谷歌的jackson

<dependency>   <groupId>com.fasterxml.jackson.core</groupId>   <artifactId>jackson-databind</artifactId>   <version>2.9.6</version> </dependency>

 

  2.9添加aspectj

<dependency>   <groupId>org.aspectj</groupId>   <artifactId>aspectjweaver</artifactId>   <version>1.9.1</version> </dependency>

 

 

2.10添加spring_jdbc，用来读取properities，连接数据库

<dependency>   <groupId>org.springframework</groupId>   <artifactId>spring-jdbc</artifactId>   <version>5.0.8.RELEASE</version> </dependency>

 

 

3.创建工程目录结构

3.1在java文件夹下创建dao、service、controller、pojo、utils文件夹

3.2在resources文件夹下创建spring、mybatis、resource文件夹

 

4.创建各种配置文件，资源文件

4.1配置mybatis_config.xml

在mybatis文件夹下新建文件mybatis_config.xml,添加头：

<?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">

工程使用spring托管mybatis，所以mybatis的配置文件只需要配置一下插件，数据库的连接放在spring的配置文件中

 

4.2配置properities文件

 在resource文件夹下新建db.properities文件，用来储存相关变量

mydriver=com.mysql.jdbc.Driver myurl=jdbc:mysql://localhost:3306/world myusername=数据库用户名  mypassword=数据库密码 maxCreateTaskCount=100 minIdle=5

 

4.3配置spring的xml文件

4.3.1配置dao层的spring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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">     <!--引入配置文件，扫描注解-->     <context:property-placeholder location="classpath:resource/db.properties"/>     <context:component-scan base-package="usts.dao"/>     <!--配置数据库连接池-->     <bean id="dataSource"class="com.alibaba.druid.pool.DruidDataSource">         <property name="driver" value="${mydriver}"/>         <property name="url" value="${myurl}"/>         <property name="username" value="${myusername}"/>         <property name="password" value="${mypassword}"/>         <property name="maxCreateTaskCount"value="${maxCreateTaskCount}"/>         <property name="minIdle" value="${minIdle}"/>     </bean>     <!--配置sqlSessionFactory-->     <bean id="sqlSessionFactoryBean"class="org.mybatis.spring.SqlSessionFactoryBean">         <property name="dataSource" ref="dataSource"/>         <property name="configLocation"value="classpath:mybatis/mybatis_config.xml"/>         <property name="mapperLocations"value="classpath:usts/dao/*Mapper.xml"/>     </bean>     <!--spring托管mybatis-->     <bean id="mapperScannerConfigurer"class="org.mybatis.spring.mapper.MapperScannerConfigurer">         <property name="basePackage" value="usts.dao"/>     </bean> </beans>

 

4.3.2配置service的spring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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">     <!--添加注解扫描-->     <context:component-scan base-package="usts.service"/> </beans>

 

4.3.3配置事务的spring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:tx="http://www.springframework.org/schema/tx"        xmlns:aop="http://www.springframework.org/schema/aop"        xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">     <!--配置事务管理器-->     <bean id="dataSourceTransactionManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager">         <property name="dataSource" ref="dataSource"/>     </bean>     <!--事务的详细配置-->     <!--通知的详细配置-->     <tx:advice id="adv">         <tx:attributes>             <tx:method name="*" propagation="REQUIRED"/>         </tx:attributes>     </tx:advice>     <!--配置aop，通知，切入点-->     <aop:config>         <aop:pointcut id="point" expression="execution(* usts.service.*.*(..))"/>         <aop:advisor advice-ref="adv" pointcut-ref="point"/>     </aop:config> </beans>

 

4.3.4配置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"        xmlns:mvc="http://www.springframework.org/schema/mvc"        xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">     <context:component-scan base-package="usts.controller"/>     <mvc:annotation-driven/>     <mvc:default-servlet-handler/>     <bean id="resourceViewResolver"class="org.springframework.web.servlet.view.InternalResourceViewResolver">         <property name="suffix" value=".html"/>         <property name="prefix" value="/"/>     </bean>     <bean id="multipartResolver"class="org.springframework.web.multipart.commons.CommonsMultipartResolver">         <property name="defaultEncoding" value="utf-8"></property>         <property name="maxUploadSize" value="100000"></property>     </bean> </beans>
