一、maven项目构建（此处暂略）
二、集成Spring与Mybatis
Maven引入需要的jar包——pom.xml
在pom.xml中配置所需jar包，网上可找到大量范例，此处以笔者构建的项目为例，用时需注意jar包的版本。

此处需要注意数据库名(myhappyfarm)，数据库用户名(root)，密码(“”)，以及字符编码(useUnicode=true&characterEncoding=UTF-8)，以上均以笔者所用框架为例。
jdbc.driverClass = com.mysql.jdbc.Driverjdbc.url = jdbc:mysql://localhost:3306/myhappyfarm?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNulljdbc.username = rootjdbc.password = jdbc.minPoolSize=2jdbc.maxPoolSize=20jdbc.checkoutTimeout=3000jdbc.maxStatements=50jdbc.testConnectionOnCheckin = falsejdbc.idleConnectionTestPeriod = 18000配置Spring与Mybatis配置文件——spring-mybatis.xml(命名无所谓)

<!-- 使用Spring组件扫描的方式来实现自动注入bean --><context:component-scan base-package="com.happyFarm.service.impl.**" />
log4j配置，基本无需改变，通用

- 所需jar包：
- mybatis_3.2.7.jar
- mybatis-generator-core-1.3.2-sources.jar
- mysql-connector-java-5.1.25-bin.jar
generatorConfig.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"><generatorConfiguration> <classPathEntry location="E:\Documents and Settings\Administrator\workspace\happyFarm\src\main\webapp\WEB-INF\lib\mysql-connector-java-5.0.3-bin.jar" /> <context id="DB2Tables" targetRuntime="MyBatis3"> <commentGenerator> <property name="suppressAllComments" value="true" /> </commentGenerator> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/myhappyfarm?useUnicode=true&characterEncoding=UTF-8" userId="root" password=""> </jdbcConnection> <javaTypeResolver> <property name="forceBigDecimals" value="false" /> </javaTypeResolver> <!-- generate Model --> <javaModelGenerator targetPackage="com.happyFarm.model" targetProject="E:\Documents and Settings\Administrator\workspace\happyFarm\src\main\java"> <property name="enableSubPackages" value="true" /> <property name="trimStrings" value="true" /> </javaModelGenerator> <!-- generate xml --> <sqlMapGenerator targetPackage="com.happyFarm.mapper" targetProject="E:\Documents and Settings\Administrator\workspace\happyFarm\src\main\java"> <property name="enableSubPackages" value="true" /> </sqlMapGenerator> <!-- generate Mapper --> <javaClientGenerator targetPackage="com.happyFarm.dao" targetProject="E:\Documents and Settings\Administrator\workspace\happyFarm\src\main\java" type="XMLMAPPER"> <property name="enableSubPackages" value="true" /> </javaClientGenerator> <table schema="" tableName="cropbasic" domainObjectName="CropBasic" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> </table> <table schema="" tableName="cropgrowthinfo" domainObjectName="CropGrowthInfo" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> </table> <table schema="" tableName="cropstoreinfo" domainObjectName="CropStoreInfo" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> </table> <table schema="" tableName="friendslist" domainObjectName="FriendsList" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> </table> <table schema="" tableName="harvestlist" domainObjectName="HarvestList" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> </table> <table schema="" tableName="plantinfo" domainObjectName="PlantInfo" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> </table> <table schema="" tableName="seedstoreinfo" domainObjectName="SeedStoreInfo" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> </table> <table schema="" tableName="userbasic" domainObjectName="UserBasic" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> </table> <table schema="" tableName="userinfo" domainObjectName="UserInfo" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> </table> </context></generatorConfiguration>- 其中，jdbcConnection为数据库连接配置，需注意用户名密码及编码；
- javaModelGenerator、sqlMapGenerator、javaClientGenerator分别对应自动生成实体类，*Mapper.xml，以及dao层的文件夹名称
- table表示表名，以及生成的实体对象名
- DOS命令行进入lib目录（这里需要注意的是，三个jar包和generatorConfig.xml需要在同一目录下，否则会找不到jar包）
- 执行java -jar mybatis-generator-core-1.3.1.jar -configfile generatorConfig.xml -overwrite
- 完成后即可在指定文件夹看到生成的model,dao,以及mapper
- 所需jar包：
依照写好的dao，实体类等编写相应的service层及实现类，至此完成spring与mybatis整合
配置springMVC配置文件——spring-mvc.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:p="http://www.springframework.org/schema/p" 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-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/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 --> <context:component-scan base-package="com.happyFarm.controller" /> <!--避免IE执行AJAX时，返回JSON出现下载文件 --> <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> </list> </property> </bean> <!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <list> <ref bean="mappingJacksonHttpMessageConverter" /> <!-- JSON转换器 --> </list> </property> </bean> <!-- 定义跳转的文件的前后缀 ，视图模式配置--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 --> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> <!-- 配置文件上传，如果没有使用文件上传可以不用配置，当然如果不配，那么配置文件中也不必引入上传组件包 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 默认编码 --> <property name="defaultEncoding" value="utf-8" /> <!-- 文件大小最大值 --> <property name="maxUploadSize" value="10485760000" /> <!-- 内存中的最大值 --> <property name="maxInMemorySize" value="40960" /> </bean> </beans>
8.配置web.xml文件
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" ><web-app> <display-name>Archetype Created Web Application</display-name> <!-- Spring和mybatis的配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-application.xml</param-value> </context-param> <!-- 编码过滤器 --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <async-supported>true</async-supported> <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监听器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 防止Spring内存溢出监听器 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <!-- Spring MVC servlet --> <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> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <!-- 此处可以可以配置成*.do，对应struts的后缀习惯 --> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list></web-app> 至此，完成ssm框架搭建的小结，编码时需注意注解等事项，待补充
