datasource

问题 I'm having problems with filters. I decided to implement my personal datasource and not to use the MatTableDataSource and therefore I don't have the filter method available. I can capture the event from the HTML and then pass it to the component and from the component pass it to the datasource. The only problem is that even if the filter is received, the table does not update as if there were no event emitter that I don't know how to implement. For example, if I insert the filter and change

问题 I'm currently trying Spring Data Flow Server with Spring Batches. I have two datasources in my application.properties. And the Spring Batch application works fine and it reads and writes data into the Database. But When I tried to deploy the Jar file in Spring Cloud Data Flow server, the SCDF doesn't load the properties from application.properties file and loads the default h2 config. I also tried passing the config as arguments when the starting the SCDF, but I get Oracle Driver not found in

问题 I normally have no problem with binding a DataSource to a GridControl. I usually so something like this: myGrid.DataSource = myList // BindingList<ComplexObject> colMyStrings.FieldName = "PropertyNameOfComplexObject"; and it works fine. I can add and delete rows from the grid and they will get added to / deleted from the DataSource "myList". So I basically always see what's in my List. But now I don't have a List<ComplexObject> , where the Generic Type has Properties, but I have a List filled

问题 I am currently having trouble with my dataSource bean creation on condition of String property from my applications.yaml file. Ideally, I would only like to create the dataSource bean only if the url is set in my application.yaml file. Shouldn't create the bean if its not present (empty or null). I know this condition checks on boolean but is there anyway to check if the string property is empty or null? DatabaseConfig.java @Configuration public class DatabaseConfig { @Value("${database.url:}

问题 I am in development phase, trying to use in-memory DB and load it with some data during Grails application start up. My question is, is there any way to write/configure SQL insert statements that can be executed during startup. 回答1: You can do this in BootStrap.groovy. If you add a dependency injection for the dataSource bean you can use it with a groovy.sql.Sql instance to do inserts: import groovy.sql.Sql class BootStrap { def dataSource def init = { servletContext -> def sql = new Sql
