Specifying table and field names for join tables in Spring Boot/Hibernate/JPA -


i using spring boot/jpa backed mysql. have db provisioned , plan on using hibernate.hbm2ddl.auto = validate (so hibernate doesn't try create db me, instead uses 1 supply , "validates" against entities define in code).

i have several many-to-many relationships entities, such book , author:

// groovy pseudo code! 1 book can have multiple authors, , // single author can have written many books. @entity class book {     @id     @generatedvalue(strategy=generationtype.identity)     long id      @column(name="title")     string title      @manytomany     list<author> authors }  @entity class author {     @id     @generatedvalue(strategy=generationtype.identity)     long id      @column(name="name")     string name      @manytomany     list<book> books }

here, classes represented following tables:

[books] id bigint unsigned not null auto_increment # primary key title varchar(50) not null  [authors] id bigint unsigned not null auto_increment # primary key name varchar(100) not null  [books_x_authors] books_x_authors_id bigint unsigned not null auto_increment # primary key book_id    # fk on books author_id  # fk on authors

where books_x_authors many-to-many or "crosswalk" table. thats db naming convention , want stick if @ possible. how configure spring boot/hibernate use books_x_authors join/crosswalk table instead of expecting perhaps table adhering own conventions?

under manytomany specify join table need

 @manytomany @jointable(name="books_x_authors",  joincolumns={@joincolumn(name="author_id"}, inversejoincolumns={@joincolumn(name="book_id")} ) list<book> books

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...

ios - Change Storyboard View using Seague -

i have following code checks connection server, , depending on want change views if no connection found. nsstring *connect = [nsstring stringwithcontentsofurl:[nsurl urlwithstring:@"http://myserver.com"] encoding:nsutf8stringencoding error:nil]; if (connect == null) { [self performseguewithidentifier:@"network_failure" sender:self]; } else { // other code here } my problem not change views. have added storyboard segue between 2 views identifier of network_failure . not have navigation controller or that, problem? thanks help! no not problem. first of all, in objectivec exists nil object oriented null . must use that. so: if(connect == nil) or better: if(!connect) so due fact nil not same of null , probably code does't enter in if scope . you have been able discover breakpoint. anyway: be sure set trigger segue (line) 2 view controller , , name network_failure (that not best name. should instead view1toview2 ) as, m...
