Spring data mongodb: Optional @Query parameter no longer works -


after upgrading spring data mongodb 1.10.1, getting errors when running queries like:

@query("{$and :["             + "{ $or : [ { $where: '?0 == null' } , { 'field1' : ?0 } ] },"             + "{ $or : [ { $where: '?1 == null' } , { 'field2' : ?1 } ] },"             + "]}") public page<entity> findall(string param1, string param2)

checking error see parameter inside clause not quoted , result get:

org.springframework.data.mongodb.uncategorizedmongodbexception: query failed error code 139 , error message 'referenceerror: test_param_value not defined :

i have seen few answers here recommending way of handling optional parameters ((spring-data-mongo - optional query parameters?)) no longer works , cannot seem find in release change log.

in case else interested, managed find workaround after checking similar ticket int spring data project.

it seems way checking null parameters in query not practice. spring developer comment: "placeholders not designed compose keys/values bind parameters. beyond that, placeholder use in quoted strings problematic in terms of escaping. using spel should suit needs"

so ended using spel checks on parameters , works fine. how looks:

@query("{$and :["          + "?#{ [0] == null ? { $where : 'true'} : { 'field1' : [0] } },"         + "?#{ [1] == null ? { $where : 'true'} : { 'field2' : [1] } },"         + "]}") public page<entity> findall(string param1, string param2, pageable pageable);

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...
