Batch insert with UUID error using mybatis in Spring boot with Postgres - spring

Question

Currently, I am trying to insert some data into through batch process. I have tried insert one by one and it works flawlessly until when i tried to put foreach in, then thing start to broke out. Please check my below code and error log.
I have a simple test table like below:
create table test(name uuid, age int);
Here is my mapper class:
#Insert("<script>",
"insert into test (name, age)",
"values ",
"<foreach collection='dmoList' item='dmo' separator=','>",
"( #{dmo.name}, #{dmo.age,jdbcType=INTEGER})",
"</foreach>",
"</script>")
// i have tried ( #{dmo.name, jdbcType=UUID} but still doesn't work
int insertBatch(#Param("dmoList") dmoList: List<HashMap<String, Object>):
Here is how i invoke this mapper method:
ArrayList<HashMap<String, Object> list = new ArrayList<HashMap<String,Object>();
Map data = new HashMap<String, Object>();
data.put("name", UUID.randomUUID());
// i have tried to use UUID.randomUUID().toString() but still not working
data.put("age", 12);
list.add(data);
insertBatch(list);
And here is the log:
2019-09-24 23:54:49.778 ERROR 85464 --- [nio-9082-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.exceptions.PersistenceException:

Answer 1

As you are using Map as the parameter, MyBatis cannot detect the type via reflection.
The simplest solution is to specify typeHandler explicitly in the parameter reference.
#{dmo.name,typeHandler=package.UuidTypeHandler}
For completeness, here is the UUID type handler for PostgreSQL which uses PreparedStatement#setObject() and ResultSet#getObject().
For other DBs that don't have UUID data type, you may need to use other methods (e.g. setString(), setBytes()) depending on the database data type you use.
package typehandler;
import java.sql.CallableStatement;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.UUID;
import org.apache.ibatis.type.BaseTypeHandler;
import org.apache.ibatis.type.JdbcType;
public class UuidTypeHandler extends BaseTypeHandler<UUID> {
#Override
public void setNonNullParameter(PreparedStatement ps, int i, UUID parameter, JdbcType jdbcType) throws SQLException {
ps.setObject(i, parameter);
}
#Override
public UUID getNullableResult(ResultSet rs, String columnName) throws SQLException {
return rs.getObject(columnName, UUID.class);
}
#Override
public UUID getNullableResult(ResultSet rs, int columnIndex) throws SQLException {
return rs.getObject(columnIndex, UUID.class);
}
#Override
public UUID getNullableResult(CallableStatement cs, int columnIndex) throws SQLException {
return cs.getObject(columnIndex, UUID.class);
}
}
