Method to retrieve the JDBC template.a) setJdbcTemplate()b) getTemplate()c) getJdbc()d) getJdbcTemplate()Answer: dExplanation: In your DAO methods, you can simply call the getJdbcTemplate() method to retrieve the JDBC template. You also have to delete the dataSource and jdbcTemplate properties, as well as their setter methods, from your DAO class, because they have already been inherited. Again, for simplicity’s sake, only the change to the insert() method is shown.Sanfoundry Global Education & Learning Series – Java Spring.To practice all areas of Java Spring, here is complete set of 1000+ Multiple Choice Questions and Answers.Participate in the Sanfoundry Certification contest to get free Certificate of Merit.
