如何执行批量插入?

Posted 2021-03-01 programb

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();

finally {

sqlsession.close();
