This is regarding code quality and coding standards with respect to Spring Ecosystem. Here there are two methods:
isRecordExists
is using a class level static constantString
query. (Definitely suggestable for old way where we use prepared statements)isRecordExists2
is using method levelString
query
Which method is better (isRecordExists
or isRecordExists2
) in context with Spring Boot?
@Repositorypublic class SpringRepository { @Autowired private NamedParameterJdbcTemplate namedParamJdbcTemplate; private static final String QUERY = " select * from Dual where created_date=:date"; public void isRecordExists(Date date){ /** * using constant for sql Query String at class level */ MapSqlParameterSource parameters = new MapSqlParameterSource(); parameters.addValue("date", date); namedParameterJdbcTemplate.queryForObject(QUERY, parameters, Integer.class); } public void isRecordExists2(Date date){ String sqlQuery=" select * from Dual where created_date=:date"; /** * using sql Query at method level */ MapSqlParameterSource parameters = new MapSqlParameterSource(); parameters.addValue("date", date); namedParameterJdbcTemplate.queryForObject(sqlQuery, parameters, Integer.class); }
