You need to perform batch insert.

int batchSize = 100;
try (SqlSession sqlSession = sqlSessionFactory.openSession(ExecutorType.BATCH)) {
  YourMapper mapper = sqlSession.getMapper(YourMapper.class);
  int size = list.size();
  for (int i = 0; i < size;) {
    mapper.insertRecord(list.get(i));
    i++;
    if (i % batchSize == 0 || i == size) {
      sqlSession.flushStatements();
      sqlSession.clearCache();
    }
  }
  sqlSession.commit();
}

You should find an appropriate value for the batchSize (it depends on various factors).

The insert statement is pretty straight forward.

<insert id="insertRecord">
  INSERT INTO MYTABLE (COLUMN1, COLUMN2, COLUMN3)
  VALUES (#{addrElement.element1}, #{addrElement.element2}, #{addrElement.element3})
</insert>
