MyBatis如何执行批量插入数据？

Posted 2021-09-13 四猿外

首先,创建一个简单的insert语句:

<insert id=”insertname”>
insert into names (name) values (#{value})
</insert>

然后在java代码中像下面这样执行批处理插入:

list<string> names = new arraylist();
names.add(“fred”);
names.add(“barney”);
names.add(“betty”);
names.add(“wilma”);

// 注意这里 executortype.batch
sqlsession sqlsession = sqlsessionfactory.opensession(executortype.batch);
try {
namemapper mapper = sqlsession.getmapper(namemapper.class);
for (string name : names) {
mapper.insertname(name);
}
sqlsession.commit();
}catch(Exception e){
e.printStackTrace();
sqlSession.rollback();
throw e;
}
finally {
sqlsession.close();
}
