java搭建 SpringMVC+Mybatis(SMM)+mybatis-generate
搭建SSM系统，首先要了解整个过程：
1、创建spring-mvc项目
2、在maven中添加要引用的jar包（使用框架都是较新的版本：）
3、 jdbc.xml +spring-mybatis.xml的配置，
4、Log4j的配置
5、配置 spring-mvc.xml+web.xml
6、配置 generatorConfig.xml
7、测试及注意事项
1、创建项目，在这里首先给出资源文件结构图（红色圈中的为下面要添加修改的文件）
2、Maven引入需要的JAR包

3、Spring与MyBatis的整合
3.1 配置数据库连接（jdbc.properties）
1 jdbc.driverClassName=oracle.jdbc.driver.OracleDriver
2 jdbc.url=jdbc:oracle:thin:@数据库地址:orcl
3 jdbc.username=用户名
4 jdbc.password=密码
3.2 建立spring-mybatis.xml配置文件（这个文件就是用来完成spring和mybatis的整合的。这里面也没多少行配置，主要的就是自动扫描，自动注入，配置数据库。注释也很详细，大家看看就明白了。）
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" xmlns:p="http://www.springframework.org/schema/p"
4 xmlns:context="http://www.springframework.org/schema/context"
5 xmlns:tx="http://www.springframework.org/schema/tx"
6 xsi:schemaLocation="http://www.springframework.org/schema/beans
7 http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
8 http://www.springframework.org/schema/context
9 http://www.springframework.org/schema/context/spring-context-3.1.xsd
10 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
11
12 <!-- 引入配置文件 -->
13 <bean id="propertyConfigurer"
14 class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
15 <property name="location" value="classpath:jdbc.properties" />
16 </bean>
17
18 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
19 destroy-method="close">
20 <property name="driverClassName" value="${jdbc.driverClassName}" />
21 <property name="url" value="${jdbc.url}" />
22 <property name="username" value="${jdbc.username}" />
23 <property name="password" value="${jdbc.password}" />
24 </bean>
25
26 <!-- Transaction manager for a single JDBC DataSource -->
27 <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
28 <property name="dataSource" ref="dataSource"/>
29 </bean>
30
31 <tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/>
32
33 <bean id="transactionTemplate"
34 class="org.springframework.transaction.support.TransactionTemplate">
35 <property name="transactionManager" ref="transactionManager"/>
36 </bean>
37
38 <!-- Activates scanning of @Autowired -->
39 <context:annotation-config/>
40 <context:component-scan base-package="com.huanshare.mapper"/>
41
42 <!-- scan for mappers and let them be autowired -->
43 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
44 <property name="basePackage" value="com.huanshare.mapper"/>
45 <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
46 </bean>
47
48 <!-- define the SqlSessionFactory -->
49 <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
50 <property name="dataSource" ref="dataSource"/>
51 <property name="typeAliasesPackage" value="com.huanshare.mapper"/>
52 <property name="mapperLocations" value="classpath:/mapper/*.xml"></property>
53 </bean>
54 </beans>
4、配置log4j.properties（Log4j的配置很简单，而且也是通用的，下面给出一个基本的配置，换到其他项目中也无需做多大的调整）
1 log4j.rootLogger=INFO,Console,File
2 #定义日志输出目的地为控制台
3 log4j.appender.Console=org.apache.log4j.ConsoleAppender
4 log4j.appender.Console.Target=System.out
5 #可以灵活地指定日志输出格式，下面一行是指定具体的格式
6 log4j.appender.Console.layout = org.apache.log4j.PatternLayout
7 log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
8
9 #文件大小到达指定尺寸的时候产生一个新的文件
10 log4j.appender.File = org.apache.log4j.RollingFileAppender
11 #指定输出目录
12 log4j.appender.File.File = logs/ssm.log
13 #定义文件最大大小
14 log4j.appender.File.MaxFileSize = 10MB
15 # 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志
16 log4j.appender.File.Threshold = ALL
17 log4j.appender.File.layout = org.apache.log4j.PatternLayout
18 log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n
5、最后整合
5.1、配置springmvc.xml
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:context="http://www.springframework.org/schema/context"
5 xsi:schemaLocation="http://www.springframework.org/schema/beans
6 http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
7 http://www.springframework.org/schema/context
8 http://www.springframework.org/schema/context/spring-context-3.1.xsd">
9
10 <context:component-scan base-package="com.huanshare" />
11
12 <!-- 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 -->
13 <bean id="multipartResolver"
14 class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
15 <!-- 默认编码 -->
16 <property name="defaultEncoding" value="utf-8" />
17 <!-- 文件大小最大值 -->
18 <property name="maxUploadSize" value="10485760000" />
19 <!-- 内存中的最大值 -->
20 <property name="maxInMemorySize" value="40960" />
21 </bean>
22
23 </beans>
5.2、配置mvc-dispatcher-servlet.xml
1 <beans xmlns="http://www.springframework.org/schema/beans"
2 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
3 xmlns:mvc="http://www.springframework.org/schema/mvc"
4 xsi:schemaLocation="http://www.springframework.org/schema/beans
5 http://www.springframework.org/schema/beans/spring-beans.xsd
6 http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
7
8
9 <!--引入配置文件-->
10 <import resource="classpath:spring-mvc.xml"/>
11 <import resource="classpath:spring-mybatis.xml"/> <!--配置页面加载js,css文件-->
12 <mvc:annotation-driven />
13 <mvc:resources mapping="/statics/**" location="/statics/" />
14 <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
15 <property name="prefix" value="/WEB-INF/pages/"/>
16 <property name="suffix" value=".jsp"/>
17 </bean>
18 </beans>
5.3、配置web.xml
<web-app version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <display-name>Spring MVC Application</display-name>
<servlet>
<servlet-name>mvc-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet> <servlet-mapping>
<servlet-name>mvc-dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--配置编码UTF-8-->
<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> </web-app>
6、配置 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>
<!-- C:/Users/jun.li/.m2/repository C:/Documents and Settings/alan/.m2/repository/mysql/mysql-connector-java/5.1.9/mysql-connector-java-5.1.9.jar
C:/Users/zhiqiang.ma/.m2/repository/com/zhaogang/jdbc/ojdbc14/10.2.0.4.0/ojdbc14-10.2.0.4.0.jar -->
<classPathEntry location="D:\ojdbc6-11.2.0.1.0.jar"></classPathEntry> <context id="context1">
<commentGenerator>
<!-- 是否去除自动生成的注释 true：是 ： false:否 -->
<property name="suppressAllComments" value="true"/>
</commentGenerator> <jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver"
connectionURL="jdbc:oracle:thin:@数据库地址:orcl" userId="用户名"
password="密码"/> <!-- 默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer true，把JDBC DECIMAL 和
NUMERIC 类型解析为java.math.BigDecimal -->
<javaTypeResolver>
<property name="forceBigDecimals" value="false"/>
</javaTypeResolver>
<javaModelGenerator targetPackage="com.huanshare.model"
targetProject="src/main/java"/>
<!-- mapper接口存放目录 -->
<sqlMapGenerator targetPackage="mapper"
targetProject="src/main/resources"/>
<javaClientGenerator targetPackage="com.huanshare.mapper"
targetProject="src/main/java" type="XMLMAPPER"/> <!-- 配置不生成Exmaple文件 -->
<table tableName="T_PERSONS" domainObjectName="TDataCarriers"
enableCountByExample="false" enableUpdateByExample="false"
enableDeleteByExample="false" enableSelectByExample="false"
selectByExampleQueryId="false">
</table> </context>
</generatorConfiguration>
7、省略，具体测试要看自己的项目情况
不过在这里，我要说，对于各层之间的方法调用，声明对象，采用注解方式@Autowired，new对象是取不到mapper接口的对象的
