MyBatis批量操作_ORACLE

阅读前，请先阅读MyBatis批量操作_MySql

jdbc.properties

 

jdbc.driverClassName=oracle.jdbc.driver.OracleDriver
jdbc.url=jdbc:oracle:thin:@//127.0.0.1:1521/orcl
jdbc.username=mybatis
jdbc.password=mybatis

 在这里说说与mysql不同的，相同的就不再叙述了

 

Test方法

 

//通过list进行批量插入
	@Test
	public void batchInsertStudentWithListOracle(){
		  List<Student> list= new ArrayList<Student>();
		    for(int i = 2;i < 10;i++){
		        Student student = new Student();
		        student.setName("test" + i);
		        student.setId(i);
		        list.add(student);
		    }
		    int n=studentMapper.batchInsertStudentWithListOracle(list);
		    System.out.println("成功插入"+n+"条记录");
		    sqlSession.commit();
	}
