3. web.xml配置

  1. 全局初始化参数,配置spring配置文件的位置

  2. 监听器,IOC容器对象会放到Application域中

  3. 前端控制器

  4. 处理乱码的过滤器

  5. 使用rest风格的url,将页面普通的post请求转为指定的delete或者put请求

     <!-- 配置spring监听,启动服务器自动加载spring监听。 -->
     <context-param>
     	<!-- 全局初始化参数    指定spring配置文件的位置 -->
     	<param-name>contextConfigLocation</param-name>
     	<param-value>classpath:applicationContext.xml</param-value>
     </context-param>
     <listener>
     	<!-- 注册监听, 作用,是当前项目被放到服务器上运行,会自动创建spring IOC容器对象,然后把创建好的容器对象放到application -->
     	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
     </listener>
     <!--2、springmvc的前端控制器,拦截所有请求  -->
     <!-- The front controller of this Spring Web application, responsible for handling all application requests -->
     <servlet>
     	<servlet-name>dispatcherServlet</servlet-name>
     	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
     	<!-- <init-param> 
     		<param-name>contextConfigLocation</param-name> 
     		<param-value>classpath:spingmvc.xml</param-value> 
     	</init-param> -->
     	<load-on-startup>1</load-on-startup>
     </servlet>
     <!-- Map all requests to the DispatcherServlet for handling -->
     <servlet-mapping>
     	<servlet-name>dispatcherServlet</servlet-name>
     	<url-pattern>/</url-pattern>
     </servlet-mapping>
     <!-- 3、字符编码过滤器,一定要放在所有过滤器之前 -->
     <filter>
     	<filter-name>CharacterEncodingFilter</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>forceRequestEncoding</param-name>
     		<param-value>true</param-value>
     	</init-param>
     	<init-param>
     		<param-name>forceResponseEncoding</param-name>
     		<param-value>true</param-value>
     	</init-param>
     </filter>
     <filter-mapping>
     	<filter-name>CharacterEncodingFilter</filter-name>
     	<url-pattern>/*</url-pattern>
     </filter-mapping>
     
     <!-- 4、使用Rest风格的URI,将页面普通的post请求转为指定的delete或者put请求 -->
     <filter>
     	<filter-name>HiddenHttpMethodFilter</filter-name>
     	<filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
     </filter>
     <filter-mapping>
     	<filter-name>HiddenHttpMethodFilter</filter-name>
     	<url-pattern>/*</url-pattern>
     </filter-mapping>
    

4. springmvc配置文件

因为没有在web.xml中配置springmvc的配置文件的名称和位置,所以默认在WEB-INF下名字为dispatcherServlet-servlet.xml

在dispatcherServlet-servlet.xml中配置

  1. 扫描所有的controller注解

  2. 配置视图解析器

  3. 两个标准配置 将springmvc不能处理的请求交给Tomcat等

     <context:component-scan base-package="com.igeek" use-default-filters="false">
     	<!--只扫描控制器。   -->
     	<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
     </context:component-scan>
     <!--配置视图解析器,方便页面返回  -->
     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
     	<property name="prefix" value="/WEB-INF/views/"></property>
     	<property name="suffix" value=".jsp"></property>
     </bean>
     <!--两个标准配置  -->
     <!-- 将springmvc不能处理的请求交给tomcat -->
     <mvc:default-servlet-handler/>
     <!-- 能支持springmvc更高级的一些功能,JSR303校验,快捷的ajax...映射动态请求 -->
     <mvc:annotation-driven/>
    

5. applicationContext.xml

  1. 扫描包,扫描除了controller注解的所有注解

  2. 加载外部文件

  3. c3p0连接池

  4. 整合mybatis sqlSessionFactory

  5. 配置扫描器,将mybatis接口的实现加入到IOC容器

  6. 配置一个可以执行批量的SQLSession

  7. 事务控制的配置

  8. 开启基于注解的事务aop

  9. 配置事务增强

     <context:component-scan base-package="com.igeek">
     	<context:exclude-filter type="annotation"
     		expression="org.springframework.stereotype.Controller" />
     </context:component-scan>
    
     <!-- Spring的配置文件,这里主要配置和业务逻辑有关的 -->
     <!--=================== 数据源,事务控制,xxx ================-->
     <context:property-placeholder location="classpath:dbconfig.properties" />
     
     <!-- c3p0 数据库连接池 。。。 -->
     <bean id="pooledDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
     	<property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>
     	<property name="driverClass" value="${jdbc.driverClass}"></property>
     	<property name="user" value="${jdbc.user}"></property>
     	<property name="password" value="${jdbc.password}"></property>
     </bean>
    
     <!--================== 配置和MyBatis的整合=============== -->
     <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
     	<!-- 指定mybatis全局配置文件的位置 -->
     	<property name="configLocation" value="classpath:mybatis-config.xml"></property>
     	<property name="dataSource" ref="pooledDataSource"></property>
     	<!-- 指定mybatis,mapper文件的位置 -->
     	<property name="mapperLocations" value="classpath:mapper/*.xml"></property>
     	
     </bean>	
    
     <!-- 配置扫描器,将mybatis接口的实现加入到ioc容器中 -->
     <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
     	<!--扫描所有dao接口的实现,加入到ioc容器中 -->
     	<property name="basePackage" value="com.igeek.crud.dao"></property>
     </bean>
     
     <!-- 配置一个可以执行批量的sqlSession -->
     <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
     	<constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory"></constructor-arg>
     	<constructor-arg name="executorType" value="BATCH"></constructor-arg>
     </bean>
     <!--=============================================  -->
    
     <!-- ===============事务控制的配置 ================-->
     <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
     	<!--控制住数据源  -->
     	<property name="dataSource" ref="pooledDataSource"></property>
     </bean>
     
     <!--开启基于注解的事务,使用xml配置形式的事务(必要主要的都是使用配置式)  -->
     <aop:config>
     	<!-- 切入点表达式 -->
     	<aop:pointcut expression="execution(* com.igeek.crud.service..*(..))" id="txPoint"/>
     	<!-- 配置事务增强 -->
     	<aop:advisor advice-ref="txAdvice" pointcut-ref="txPoint"/>
     </aop:config>
     
     <!--配置事务增强,事务如何切入  -->
     <tx:advice id="txAdvice" transaction-manager="transactionManager">
     	<tx:attributes>
     		<!-- 所有方法都是事务方法 -->
     		<tx:method name="*"/>
     		<!--以get开始的所有方法  -->
     		<tx:method name="get*" read-only="true"/>
     	</tx:attributes>
     </tx:advice>
    

6. mybatis配置文件

  1. 开启驼峰命名

  2. 批量注册别名

  3. 分页参数合理化

     <typeAliases>
     	<!-- 批量注册别名。 -->
     	<package name="com.igeek.crud.bean"/>
     </typeAliases>
     
     <plugins>
     	<plugin interceptor="com.github.pagehelper.PageInterceptor">
     		<!--分页参数合理化  -->
     		<property name="reasonable" value="true"/>
     	</plugin>
     </plugins>
    

7. 逆向工程

创建mbg.xml放到根目录下

<?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>

	<context id="DB2Tables" targetRuntime="MyBatis3">
		<commentGenerator>
			<property name="suppressAllComments" value="true" />
		</commentGenerator>
		<!-- 配置数据库连接 -->
		<jdbcConnection driverClass="com.mysql.jdbc.Driver"
			connectionURL="jdbc:mysql://localhost:3306/ssm" userId="root"
			password="root">
		</jdbcConnection>

		<javaTypeResolver>
			<property name="forceBigDecimals" value="false" />
		</javaTypeResolver>

		<!-- 指定javaBean生成的位置 -->
		<javaModelGenerator targetPackage="com.igeek.crud.bean"
			targetProject=".\src\main\java">
			<property name="enableSubPackages" value="true" />
			<property name="trimStrings" value="true" />
		</javaModelGenerator>

		<!--指定sql映射文件生成的位置 -->
		<sqlMapGenerator targetPackage="mapper" targetProject=".\src\main\resources">
			<property name="enableSubPackages" value="true" />
		</sqlMapGenerator>
		
		
		<!-- 指定dao接口生成的位置,mapper接口 -->
		<javaClientGenerator type="XMLMAPPER"
			targetPackage="com.igeek.crud.dao" targetProject=".\src\main\java">
			<property name="enableSubPackages" value="true" />
		</javaClientGenerator>


		<!-- table指定每个表的生成策略 -->
		<table tableName="employee" domainObjectName="Employee"></table>
		<table tableName="department" domainObjectName="Department"></table>
	</context>
</generatorConfiguration>

在测试包中生成相应的mapper.xml,bean,mapper接口

public class MBGTest {

	public static void main(String[] args) throws Exception {
		// TODO Auto-generated method stub
		List<String> warnings = new ArrayList<String>();
		boolean overwrite = true;
		File configFile = new File("mbg.xml");
		ConfigurationParser cp = new ConfigurationParser(warnings);
		Configuration config = cp.parseConfiguration(configFile);
		DefaultShellCallback callback = new DefaultShellCallback(overwrite);
		MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config,
				callback, warnings);
		myBatisGenerator.generate(null);
	}

}
