java - How to initialize NamedParameterJdbcTemplate variable -

my code looks this:

namedparameterjdbctemplate stmt; string sql = "insert ....."; // <- insert statement map<string, object> named = ...; ... stmt.update(sql, named);

but when try compile program, i'm getting error message:

variable stmt might not have been initialized

stmt.update(sql, named);

^

1 error

in examples (like one), i've seen namedparameterjdbctemplate variable not initialized @ all. so, wonder i'm doing wrong here.

in tutorial, life cycle of namedparameterjdbctemplate managed spring.

if not using namedparameterjdbctemplate in spring context, can create namedparameterjdbctemplate datasource or jdbctemplate.
