## 3：springmvc配置---dispatcher-servlet.xml ##

之后像路径直接映射页面，配置国际化解析器等后续使用的话再添加；

## 4：mybatis的配置，是整合的关键配置 ##

mybaits配置最关键的是将mybatis控制的数据源有spring提供；而且将mybatis交由spring管理

mybatis-config.xml：

<?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>
            <setting name="mapUnderscoreToCamelCase" value="true"/>
            <setting name="lazyLoadingEnabled" value="true"/>
            <setting name="aggressiveLazyLoading" value="false"/>
            
            <setting name="cacheEnabled" value="true"/>
        </settings>
    
    </configuration>

下边都是在spring配置文件（applicationContext.xml）中的：

配置思路；将mybaits的最核心的sqlSessionFactory交给spring来处理；这样需要导入mybatis-spring这个中间整合包；

还需要将dao的实现加入到容器中，这样我们在别的组件就能使用dao了；否则还得将系统的

<bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
            
            <property name="configLocation" value="classpath:mybatis/mybatis-config.xml"></property>
            
            <property name="dataSource" value="dataSource"></property>
            
            <property name="mapperLocations" value="classpath:mybatis/mapper/*.xml"></property>
        </bean>
    
        
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
            <property name="basePackage" value="com.wkl.dao"></property>
        </bean>

# 三：测试 #

## 1：代码： ##

controller层：

package com.wkl.controller;
    
    import com.wkl.bean.Employee;
    import com.wkl.services.EmployeeServices;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestParam;
    
    import java.util.Map;
    
    /**
     * Description:
     * Date:       2020/8/26 - 下午 9:55
     * author:     wangkanglu
     * version:    V1.0
     */
    @Controller
    public class EmployeeController {
    
        @Autowired
        EmployeeServices employeeServices;
    
        @RequestMapping("getEmployee")
        public String getEmployee(@RequestParam("id")Integer id, Map map){
            System.out.println("id:"+id);
            Employee employee = employeeServices.getEmployee(id);
            System.out.println("employee:"+employee);
            map.put("employee",employee);
            return "success";
        }
    }

services层：

package com.wkl.services;
    
    import com.wkl.bean.Employee;
    import com.wkl.dao.EmployeeDao;
    import org.apache.ibatis.session.SqlSession;
    import org.apache.ibatis.session.SqlSessionFactory;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;
    
    /**
     * Description:
     * Date:       2020/8/26 - 下午 8:28
     * author:     wangkanglu
     * version:    V1.0
     */
    @Service
    public class EmployeeServices {
    
        @Autowired
        EmployeeDao employeeDao;
    
        public Employee getEmployee(Integer id){
            Employee employee = employeeDao.getEmployee(id);
            return employee;
        }
    
    }

dao层：这层没有加注解，是由mybatis使用，但是通过配置由spring来控制的；

package com.wkl.dao;
    
    
    import com.wkl.bean.Employee;
    
    /**
     * Description:
     * Date:       2020/8/19 - 下午 4:31
     * author:     wangkanglu
     * version:    V1.0
     */
    public interface EmployeeDao {
    
    
        public Employee getEmployee(Integer id);
    
    }

dao层的mapper.xml：

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE mapper
            PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
            "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
    
    <mapper namespace="com.wkl.dao.EmployeeDao">
    
    
        
        
        <select id="getEmployee" resultType="com.wkl.bean.Employee" useCache="true">
            select * from t_employee where id =#{id}
        </select>
    
    
    </mapper>
