在MyBatis中處理Blob和Clob類型的數據,可以通過以下方式來實現:
public interface MyMapper {
void insertBlobData(@Param("blobData") Blob blobData);
void insertClobData(@Param("clobData") Clob clobData);
}
<insert id="insertBlobData" parameterType="java.sql.Blob">
INSERT INTO my_table(blob_data) VALUES(#{blobData})
</insert>
<insert id="insertClobData" parameterType="java.sql.Clob">
INSERT INTO my_table(clob_data) VALUES(#{clobData})
</insert>
Blob blobData = connection.createBlob();
blobData.setBytes(1, "blob_data".getBytes());
Clob clobData = connection.createClob();
clobData.setString(1, "clob_data");
MyMapper mapper = sqlSession.getMapper(MyMapper.class);
mapper.insertBlobData(blobData);
mapper.insertClobData(clobData);
通過以上方式,就可以在MyBatis中處理Blob和Clob類型的數據。
