How to use JdbcTemplate to execute Join requests

I have the following database model

       create table Diary (id bigint NOT NULL AUTO_INCREMENT,
                creationDate TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
                name varchar(255) not null, 
                description text,
                viewtype varchar(255) not null,
                member bigint,
                primary key (id),
                foreign key (member) references Member(id));


       create table Page (id bigint NOT NULL AUTO_INCREMENT,
                creationDate TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
                viewtype varchar(255) not null,
                diary bigint,
                member bigint,
                primary key (id),
                foreign key (diary) references Diary(id),
                foreign key (member) references Member(id));

       create table Comment (id bigint NOT NULL AUTO_INCREMENT,
                postingDate TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
                comment text not null,
                page bigint,
                member bigint,
                primary key (id),
                foreign key (page) references Page(id)
                foreign key (member) references Member(id));

I am using spring JDbc template.

      My interface looks like follows: accountid is the memeberid in the database.

     Collection<Diary> getDiaries(Long accountId);

And my diary is as follows:

           public class Diary {
           private Collection<Page> pages;
           private Long id;
           private LocalTime creationDate;
           private String name;
           private String description;
           private ViewType type;
           }

I wanted to know what the query would look like if I wanted to prepare a diary object using the jdbc template. You can also simply run only one request and simply prepare this Diary object, because I will avoid multiple requests for a single request. For the above interface, it is very possible that I will use the s join query or there is an easier way using the spring structure of the JDBC template.
