弄了很久，在同学的帮助下终于整合好了，下面贴出具体步骤，以后复用

1.首先，我的项目目录结构：

2. 在web.xml中配置

<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_3_0.xsd"         version="3.0">    <!-- The definition of the Root Spring Container shared by all Servlets and Filters -->    <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:spring/applicationContext.xml</param-value>    </context-param>    <!-- 用spring Encoding,解决乱码问题 -->    <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>        <init-param>            <param-name>forceEncoding</param-name>            <param-value>true</param-value>        </init-param>    </filter>    <filter-mapping>        <filter-name>encodingFilter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>    <!-- Creates the Spring Container shared by all Servlets and Filters -->    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>    <!-- Processes application requests -->    <servlet>        <servlet-name>springMvc</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        <init-param>            <param-name>contextConfigLocation</param-name>            <param-value>/WEB-INF/springMvc-servlet.xml</param-value>        </init-param>        <load-on-startup>1</load-on-startup>    </servlet>    <welcome-file-list>        <welcome-file>/index.jsp</welcome-file>    </welcome-file-list>    <servlet-mapping>        <servlet-name>springMvc</servlet-name>        <url-pattern>*.action</url-pattern>    </servlet-mapping></web-app>

springMvc-servlet.xml是配置请求分配器，具体位置放在哪一目录下，无特别要求。但是要<param-value>标签中配置其路径，我的配置如下：

<?xml version="1.0" encoding="UTF-8"?><beans:beans xmlns="http://www.springframework.org/schema/mvc"             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"             xmlns:beans="http://www.springframework.org/schema/beans"             xmlns:context="http://www.springframework.org/schema/context"             xmlns:mvc="http://www.springframework.org/schema/mvc"             xsi:schemaLocation="             http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd             http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd             http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd             http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">    <!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure -->    <!-- Enables the Spring MVC @Controller programming model -->    <!-- 自动扫描且只扫描@Controller -->    <context:component-scan base-package="com.coocaa.anniecode.controller" />    <!--注解驱动-->    <mvc:annotation-driven>        <mvc:message-converters register-defaults="true">            <beans:bean class="org.springframework.http.converter.StringHttpMessageConverter">                <beans:constructor-arg value="UTF-8" />            </beans:bean>        </mvc:message-converters>    </mvc:annotation-driven>    <!-- Jackson转换器 -->    <beans:bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter" />    <!-- fastjson转换器 -->    <beans:bean id="fastJsonHttpMessageConverter"  class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter"/>    <!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory -->    <beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">        <beans:property name="prefix" value="/views/" />        <beans:property name="suffix" value=".jsp" />    </beans:bean>    <beans:bean id="maxUploadSize" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">        <beans:property name="maxUploadSize" value="32505856" /><!-- 上传文件大小限制为31M，31*1024*1024 -->        <beans:property name="maxInMemorySize" value="4096" />    </beans:bean></beans:beans>

3. 接下来时spring的配置，我在resources的文件夹下新建了spring文件夹，并在该文件夹下写applicationContext.xml，如下：

<?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-3.0.xsd">    <context:annotation-config />    <!-- 自动扫描 -->    <context:component-scan base-package="com.coocaa.anniecode" />    <import resource="../mybatis/spring-mybatis.xml"/></beans>

4. 整合spring 和mybatis，即配置文件spring-mybatis.xml文件，在applicationContext.xml中可以看出我导入了它。spring-mybatis.xml配置如下，目录是resources/mybatis：

<?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:tx="http://www.springframework.org/schema/tx"       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-3.0.xsd    http://www.springframework.org/schema/tx  http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">    <!-- 引入属性文件 -->    <context:property-placeholder location="classpath:jdbc.properties" />    <!-- 配置数据源 -->    <bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">        <property name="url" value="${jdbc.url}" />        <property name="driverClassName" value="${jdbc.driver}" />        <property name="username" value="${jdbc.username}" />        <property name="password" value="${jdbc.password}" />        <property name="initialSize" value="${initialSize}" />        <property name="maxActive" value="${maxActive}" />        <property name="minIdle" value="1" />        <property name="maxWait" value="60000" />        <property name="validationQuery" value="${validationQuery}" />        <property name="testOnBorrow" value="false" />        <property name="testOnReturn" value="false" />        <property name="testWhileIdle" value="true" />        <property name="timeBetweenEvictionRunsMillis" value="60000" />        <property name="minEvictableIdleTimeMillis" value="25200000" />        <property name="removeAbandoned" value="true" />        <property name="removeAbandonedTimeout" value="1800" />        <property name="logAbandoned" value="true" />        <property name="filters" value="mergeStat" />    </bean>    <!-- myBatis文件 -->    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">        <property name="dataSource" ref="dataSource" />        <property name="mapperLocations" value="classpath:mapper/*.xml" />    </bean>    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">        <property name="basePackage" value="com.coocaa.anniecode.mapper" />        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />    </bean>    <!-- 配置事务管理器 -->    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">        <property name="dataSource" ref="dataSource" />    </bean>    <!-- 注解方式配置事物 -->    <tx:annotation-driven transaction-manager="transactionManager" /></beans>

这里有一个mapper的xml文件的配置，也就是相当于dao接口的实现类，这些.xml文件必须得放到resources目录下，不然会找不到(目前还不知道为什么，可能还有些没有配置好)

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">        <property name="dataSource" ref="dataSource" />        <property name="mapperLocations" value="classpath:mapper/*.xml" />    </bean>

5.在spring-mybatis.xml中有配数据源，其中我引入了idbc.properties文件，该文件时数据库连接的相关设置，如下：

jdbc.driver = com.mysql.jdbc.Driverjdbc.url = jdbc:mysql://localhost:3306/testjdbc.username = rootjdbc.password = 1234validationQuery = SELECT 1 FROM DUAL#定义初始连接数initialSize = 1#定义最大连接数maxActive=20#定义最大空闲maxIdle=20#定义最小空闲minIdle=1#定义最长等待时间maxWait=60000

6.我用的maven，所以pom.xml中的一些导入如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>com.coocaa.info_gathering_web</groupId>  <artifactId>com.coocaa.info_gathering_web</artifactId>  <packaging>war</packaging>  <version>1.0-SNAPSHOT</version>  <name>com.coocaa.info_gathering_web Maven Webapp</name>  <url>http://maven.apache.org</url>  <properties>    <java-version>1.7</java-version>    <org.springframework-version>3.2.3.RELEASE</org.springframework-version>    <org.aspectj-version>1.6.10</org.aspectj-version>    <org.slf4j-version>1.6.6</org.slf4j-version>  </properties>  <dependencies>    <!-- Spring -->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-context</artifactId>      <version>${org.springframework-version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-webmvc</artifactId>      <version>${org.springframework-version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-jdbc</artifactId>      <version>${org.springframework-version}</version>    </dependency>    <dependency>      <groupId>org.apache.commons</groupId>      <artifactId>commons-lang3</artifactId>      <version>3.2.1</version>    </dependency>    <!-- AspectJ -->    <dependency>      <groupId>org.aspectj</groupId>      <artifactId>aspectjrt</artifactId>      <version>${org.aspectj-version}</version>    </dependency>    <!-- 导入dbcp的jar包，用来在applicationContext.xml中配置数据库 -->    <dependency>      <groupId>commons-dbcp</groupId>      <artifactId>commons-dbcp</artifactId>      <version>1.2.2</version>    </dependency>    <!-- Servlet -->    <dependency>      <groupId>javax.servlet</groupId>      <artifactId>servlet-api</artifactId>      <version>2.5</version>      <scope>provided</scope>    </dependency>    <dependency>      <groupId>javax.servlet.jsp</groupId>      <artifactId>jsp-api</artifactId>      <version>2.1</version>      <scope>provided</scope>    </dependency>    <dependency>      <groupId>javax.servlet</groupId>      <artifactId>jstl</artifactId>      <version>1.2</version>    </dependency>    <!-- mybatis -->    <dependency>      <groupId>org.mybatis</groupId>      <artifactId>mybatis</artifactId>      <version>3.2.1</version>    </dependency>    <dependency>      <groupId>org.mybatis</groupId>      <artifactId>mybatis-spring</artifactId>      <version>1.2.0</version>    </dependency>    <dependency>      <groupId>mysql</groupId>      <artifactId>mysql-connector-java</artifactId>      <version>5.1.22</version>    </dependency>    <!-- Test -->    <dependency>      <groupId>junit</groupId>      <artifactId>junit</artifactId>      <version>4.7</version>      <scope>test</scope>    </dependency>    <dependency>      <groupId>com.alibaba</groupId>      <artifactId>druid</artifactId>      <version>0.2.20</version>    </dependency>    <dependency>      <groupId>org.aspectj</groupId>      <artifactId>aspectjweaver</artifactId>      <version>1.7.2</version>    </dependency>    <dependency>      <groupId>com.alibaba</groupId>      <artifactId>fastjson</artifactId>      <version>1.1.34</version>    </dependency>    <dependency>      <groupId>com.fasterxml.jackson.core</groupId>      <artifactId>jackson-core</artifactId>      <version>2.2.2</version>    </dependency>    <dependency>      <groupId>com.fasterxml.jackson.core</groupId>      <artifactId>jackson-databind</artifactId>      <version>2.2.2</version>    </dependency>    <dependency>      <groupId>commons-fileupload</groupId>      <artifactId>commons-fileupload</artifactId>      <version>1.2.2</version>    </dependency>  </dependencies></project>

7.接下来，我们就可以相应地写pojo、mapper、service层了。
