今天完成的任务：

cd 到项目目录下，需要当前目录下的pom文件，否则报错

mvn compile exec:java -Dexec.mainClass="com.bbq.services.StudentService"

mvn test 

与在idea环境差别不大，不过mvn 里的镜像设置成阿里云的要快些的

try cache 部分 

在dao层直接在函数定义处 throws Exception，然后services 也直接throws，最后在main里的来处理的

import com.bbq.beans.Student;
import org.mybatis.spring.SqlSessionTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Repository;

import java.util.List;
import java.util.concurrent.ExecutionException;

@Repository
public class StudentDao {

    @Autowired
    private SqlSessionTemplate sessionTemplate;


    public List<Student> getStudentByName(final  String name) throws Exception{
        return sessionTemplate.selectList("com.bbq.dao.mapper.StudentMapper.getByName", name);
    }
    public Student getStudentById(final int id) throws Exception {
        return sessionTemplate.selectOne("com.bbq.dao.mapper.StudentMapper.getById", id);
    }
}

@Service
public class StudentService {

    @Autowired
    private StudentDao studentDao;


    public void getStudentByName(String name)  throws Exception{
        List<Student> sts = studentDao.getStudentByName(name);
        System.out.println(sts.size());
    }

    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
        BeanFactory beanFactory = (BeanFactory) context;
        StudentService ss = beanFactory.getBean("studentService", StudentService.class);
        try {
            ss.getStudentByName("朱浩");
        }
        catch (Exception e) {
            e.printStackTrace();
        }
    }
}
