第一步 编写实体类（可以使用mybatis的反向自动生成）

第二步 编写mapper接口以及映射文件（因通常都用面向接口的形式，则mapper映射文件需要和接口同一目录，也可以使用mybatis反向自动生成）

第三步 配置mybatis.xml设置全局配置，其他的写在spring配置文件

<?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">

<configuration>

<settings>
<!-- 设置log4j实现 -->
<setting name="logImpl" value="LOG4J"/>
<!-- 懒加载 -->
<setting name="lazyLoadingEnabled" value="true"/>
<!-- 按属性需要加载 -->
<setting name="aggressiveLazyLoading" value="false"/>
<!-- 开启二级缓存 -->
<setting name="cacheEnabled" value="true"/>
<!-- 设置缓存作用域 -->
<setting name="localCacheScope" value="SESSION"/>
</settings>

<!-- 设置类别名 -->
<typeAliases>
<package name="com.ssm_top1.pojo"/>
</typeAliases>

</configuration>

第四步 配置service接口以及实现

第五步 配置contorller控制类

package com.ssm_top1.controller;

import java.util.List;

import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;

import com.ssm_top1.pojo.Subjects;
import com.ssm_top1.pojo.SubjectsExample;
import com.ssm_top1.pojo.SubjectsExample.Criteria;
import com.ssm_top1.service.SubjectsService;

@Controller
@RequestMapping("/sub")
public class SubjectsController {

@Autowired
private SubjectsService subjectsService;

//参数绑定
@RequestMapping("/xiugai")
public String xiugai(HttpServletRequest request,@RequestParam("ididid")int asdasda) {
//			ModelAndView modelAndView = new ModelAndView();
Subjects sub = subjectsService.getSub(asdasda);
request.setAttribute("sub", sub);
//			modelAndView.addObject("sub", sub);
//			modelAndView.setViewName("show");
return "show";
}

@RequestMapping("/xiugaiSubmit")
public String xiugaiSubmit(Model model) {

ModelAndView modelAndView = new ModelAndView();
subjectsService.updateSub(new Subjects(1,"黑色",333,2));

return "redirect:showAll";
}

@RequestMapping("/textPOjO")
public String textPOjO(Subjects subjects) {
System.out.println(subjects.toString());
return "redirect:ssm_top1/success";
}

}

第六步 配置springMVC.xml

<?xml version="1.0" encoding="UTF-8"?>

<!-- 扫描被注解controller表示的类 -->
<context:component-scan base-package="com.ssm_top1" use-default-filters="false">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

<!-- 加载映射器 和 适配器 -->
<mvc:annotation-driven conversion-service="conversionService"/>
<mvc:default-servlet-handler/>

<!-- 配置视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/"/>
<property name="suffix" value=".jsp"/>
</bean>

<!-- 自定义参数绑定 -->
<bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
<property name="converters">
<list>
<!-- 日期转换器 -->
<bean class="com.ssm_top1.controller.conversion.DataConversion"/>
</list>
</property>
</bean>

## 第七步 配置applicationContext.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:context="http://www.springframework.org/schema/context"
xmlns:mybatis-spring="http://mybatis.org/schema/mybatis-spring"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://mybatis.org/schema/mybatis-spring http://mybatis.org/schema/mybatis-spring-1.2.xsd
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-4.3.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">

<!-- 扫描注解 mvc控制器注解不扫 -->
<context:component-scan base-package="com.ssm_top1">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

<!-- 加载数据源配置文件 -->
<context:property-placeholder location="classpath:mybatis/database.properties"/>

<!-- 配置c3p0数据源 -->
<bean id="pooledDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${mysql.driver}"/>
<property name="jdbcUrl" value="${mysql.url}"/>
<property name="user" value="${mysql.username}"/>
<property name="password" value="${mysql.password}"/>
</bean>

<!-- 加载mybatis配置文件 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="pooledDataSource"/>
<property name="configLocation" value="classpath:mybatis/mybatis-config.xml"/>
</bean>

<!-- mapper扫描器 -->
<!-- <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.ssm_top1.mapper"/>
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
</bean> -->
<mybatis-spring:scan base-package="com.ssm_top1.mapper"/>

<!-- 配置事物管理器 -->
<bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!-- 自定数据源交给spring管理 -->
<property name="dataSource" ref="pooledDataSource"/>
</bean>

<!-- 开启基于注解的事物 -->
<tx:annotation-driven transaction-manager="dataSourceTransactionManager"/>

</beans>

第八步 配置web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5">

<!-- 配置DispatcherServlet 前端控制器 -->
<servlet>
<servlet-name>springDispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<!-- 如果不配置默认加载 WEB-INF>*-servlet.xml -->
<param-value>classpath:spring/spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springDispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

<!-- 配置spring监听器 -->
<!-- needed for ContextLoaderListener -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/applicationContext-dao.xml</param-value>
</context-param>

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

</web-app>

mybatis反向自动生成配置文件

<?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用于指定生成一组对象的环境  可以配置多个-->
<context id="DB2Tables" targetRuntime="MyBatis3">

<!-- jdbcConnection元素用于指定内省表所需的数据库连接的属性。
MyBatis Generator使用JDBC的DatabaseMetaData类来发现您在配置中指定的表的属性。
每个<context>元素都需要一个<connectionFactory>或<jdbcConnection>元素。 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql:///school"
userId="root"
password="123456">
</jdbcConnection>

<!-- 此属性用于指定MyBatis生成器是否应该强制使用java.math。
用于十进制和数值字段，而不是在可能的情况下替换整数类型。属性支持以下值: 默认false   true-->
<javaTypeResolver >
<property name="forceBigDecimals" value="false" />
</javaTypeResolver>

<!-- 指定javabean生成的路径 -->
<javaModelGenerator targetPackage="com.ssm_top1.pojo" targetProject="./src/main/java">
<!--enableSubPackages 此属性用于选择MBG是否会根据自检表的目录和模式为对象生成不同的Java包。
例如，假设模式MYSCHMA中的一个表MYTABLE。还假设targetPackage属性被设置为“com.mycompany”。
如果此属性为真，则为表生成的DAO接口和类将放在“com.mycompany.myschema”包中。
如果属性为false，则生成的SQL映射将放在“com”中。mycompany”模式。
-->
<property name="enableSubPackages" value="true" />
<property name="trimStrings" value="true" />
</javaModelGenerator>

<!-- 指定xml映射文件指定生成路径 -->
<sqlMapGenerator targetPackage="com.ssm_top1.mapper"  targetProject="./src/main/resources">
<property name="enableSubPackages" value="true" />
</sqlMapGenerator>

<!-- 指定接口生成的路径 -->
<javaClientGenerator type="XMLMAPPER" targetPackage="com.ssm_top1.mapper"  targetProject="./src/main/java">
<property name="enableSubPackages" value="true" />
</javaClientGenerator>

<!-- 指定要逆向分析那些表 -->
<table tableName="subjects" domainObjectName="Subjects"/>
<table tableName="grade" domainObjectName="Grade"/>
</context>
</generatorConfiguration>
