对于问题四、五、六,我可以回答。以下是使用Mybatis完成这些功能的示例代码。
问题四的代码:
```java
public List<News> searchNewsByAuthorTitleDate(String author, String title, String startDate, String endDate) throws SQLException {
SqlSession sqlSession = sqlSessionFactory.openSession();
try {
NewsDao newsDao = sqlSession.getMapper(NewsDao.class);
return newsDao.searchNewsByAuthorTitleDate(author, title, startDate, endDate);
} finally {
sqlSession.close();
}
}
```
问题五的代码:
```java
public List<News> searchNewsByPage(int page, int pageSize) throws SQLException {
SqlSession sqlSession = sqlSessionFactory.openSession();
try {
NewsDao newsDao = sqlSession.getMapper(NewsDao.class);
int startIndex = (page - 1) * pageSize;
RowBounds rowBounds = new RowBounds(startIndex, pageSize);
return newsDao.searchNewsByPage(rowBounds);
} finally {
sqlSession.close();
}
}
```
问题六的代码:
```java
public void batchInsert(List<News> newsList) throws SQLException {
SqlSession sqlSession = sqlSessionFactory.openSession();
try {
NewsDao newsDao = sqlSession.getMapper(NewsDao.class);
for (News news : newsList) {
newsDao.insert(news);
}
sqlSession.commit();
} catch (Exception e) {
sqlSession.rollback();
throw e;
} finally {
sqlSession.close();
}
}
```
