问题 I have multiple databases in yml, how to get country specific repository? i am getting country name at runtime and based on country name i need to do operation with that country database, with single database it taking default database repository from yml. as per micronaut document : In multiple datasource scenario, the @io.micronaut.data.annotation.Repository annotation can be used to specify the datsource configuration to use. By default Micronaut Data will look for the default datasource.

问题 I am developing a web app where batch programs need to run for specific times. I used Quartz library to schedule the jobs. The web app is deployed on Websphere 8.5.5 and its working fine, accessing the tables through datasources (Datasource given in code is java:comp/env/jdbc/db_datasource ). The job is also triggered at the mentioned times. I am getting an error when the scheduled job makes a DB connection through the datasource and the error is: javax.naming.ConfigurationException: A JNDI

问题 I am developing a server application using Jboss wildfly 8.1 and JPA Hibernate. The problem is, that the JPA datasource creditials have to be loaded at runtime (password). When the server starts, it connects to an encrypted storage where it retrieves password to real database. After that, it should establish connection to the real database. I tried several things already: Lookup the datasource through JNDI and rebind it with actual DS. Lookup the entityManagerFactory through JNDI and rebind

问题 I'm trying to add items to a combo box using a data table that already has some columns but I just want one of them values into the combo box. What i'm doing is this: cbReviewers.DataSource = Reviewers_table.Columns[1]; but is not working, do you know how could I do it? 回答1: I think you need to use Display and Value members properties to work with display data. cbReviewers.DataSource = Reviewers_table cbReviewers.DisplayMember = "ColumnNameThatContainsText" cbReviewers.ValueMember =

问题 I'm using an advanced datagridview and to use the filters that come with it you need to use a binding source. I'm writing an Oracle query (actually several of them) and using the results as a datasource. I can't seem to get it to work correctly. I have googled all the solutions and have tried them all with no success. My code: public partial class frmMain : Form { private string sql; public DataGridView DVG = new DataGridView(); public BindingSource bs = new BindingSource(); private static

问题 In C# I have DataGridView populated via DataSource . With some custom made filter I determine a subset of rows (by looping through the rows and checking the conditions on columns, to be precise) and need to keep/show only these rows in the DatGridView. One option I understand is to loop through the grid and hide the rows which are outside my index set. This, however, is painfully slow for larger set of rows. My question is: given a datagridview which is bind to a datasource, and a subset of

问题 I have an existing postgres database with the database "testdb" and the database schema testdbschema". If I use the default persistence.xml configuration of RESOURCE_LOCAL the following property is working: <property name="javax.persistence.jdbc.url" value="jdbc:postgresql://server:port/testdb?currentSchema=testdbschema" /> I want to configure my database connection within my web.xml as a data-source. Everything is working well, except the configuration of the database schema. Here is my web

问题 I have a small web app built with Spring Boot that has two datasources, (one for the application data, and one for retrieving user access information). I have configured this successfully using a config class for each datasource and using datasource connection details in the application.properties file. I am now trying to refactor this to use jndi lookup for the datasource details so that I can use the same approach locally as I'll use in dev/test and prod. I have amended my database config
