Spring整合mybatis-改造service层

首先添加一下Service层

package cn.smbms.service;

import java.util.List;

import cn.smbms.pojo.User;

public interface UserService {

　　public List<User> findUsers(User user);
}

 

 

package cn.smbms.service;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Service;

import cn.smbms.dao.user.UserMapper;
import cn.smbms.pojo.User;

@Service("userService")
public class UserServiceImpl implements UserService {

@Autowired
@Qualifier("userMapper")
private UserMapper userMapper;
public UserMapper getUserMapper() {
　　return userMapper;
}
public void setUserMapper(UserMapper userMapper) {
　　this.userMapper = userMapper;
}
@Override
public List<User> findUsers(User user) {
　　// TODO Auto-generated method stub
　　return userMapper.getUserList(user);//调用的dao层的方法
　　}

}

    <!--配置数据源 -->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
        <property name="url"
            value="jdbc:mysql://localhost:3306/smbms?useUnicode=true&amp;characterEncoding=utf-8"></property>
        <property name="username" value="root"></property>
        <property name="password" value="root"></property>

    </bean>
    <!--配置SqlSessionFactoryBean -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!--获取到你的数据源 -->
        <property name="dataSource" ref="dataSource"></property>
        <!--获取到mybatis的配置文件  注意这里使用的是value属性 -->
        <property name="configLocation" value="classpath:mybatis-config.xml"></property>
        <!--使用下面这种方式获取sql文件  -->
        <property name="mapperLocations">
            <list>

    <!-- 如果在真实的项目中，映射器比较多的情况下，我们可以使用MapperScannerConfigure扫描基准包 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="cn.smbms.dao"></property>
    </bean>
    
    <!--然后改造一下的我们的service层  -->
    <!--扫描注解定义  -->
    <context:component-scan base-package="cn.smbms.service"></context:component-scan>
    
</beans>

测试方法：

    @Test
    public void testGetUserList(){
        
        User userCondition = new User();
        userCondition.setUserName("赵");
        userCondition.setUserRole(3);        
        //UserMapper userMapper=new UserMapperImpl();
        ApplicationContext ctx=new 
                ClassPathXmlApplicationContext("applicationContext.xml");
        
        
        //我们可以看下，容器为我们创建的bean的名称
        for(String name:ctx.getBeanDefinitionNames()){
            logger.info("IOC容器创建的Bean:"+name);
        }
        UserService tUserService=(UserService) ctx.getBean("userService");    
        
        
        List<User> userList = tUserService.findUsers(userCondition);
    
        for(User user: userList){
            logger.debug("testGetUserList userCode: " + user.getUserCode() + 
                        " and userName: " + user.getUserName() + 
                        " and userRole: " + user.getUserRole() + 
                        " and userRoleName: " + user.getUserRoleName() +
                        " and age: " + user.getAge() +
                        " and address: " + user.getAddress());
        }
    }
    

运行结果：
