mysql - Will NamedParameterJdbcTemplate.update wait until the transaction finishes? -

i'm using update method in namedparamameterjdbctempalte implements org.springframework.jdbc.core.namedparam.namedparameterjdbcoperations.

i looked docs , thing can find "this method issues update via prepared statement, binding given arguments."

i have code looks this

//calling jdbctemplate.update() here on foo objects //calling update on same set of foo objects (i know it's dump let's leave is) 

now question first update wait until transaction completed return, or issue request , return? when second line, have guarantee transaction issued first call update has finished?

i seem seeing mysql deadlock once in while , suspect that's because first update has not finished job when second 1 comes in.

found question, answer doesn't answer question. how avoid mysql 'deadlock found when trying lock; try restarting transaction'
