Java application can not use noria-mysql adapter #15
Description
Hey! I was trying to run Java application with Noria but I got an exception
Exception in thread "main" java.sql.SQLNonTransientConnectionException: CLIENT_SECURE_CONNECTION is required

Steps to reproduce:
- run zookeeper (docker image all ports are exposed)
- run noria from README (
cargo r --release --bin noria-server -- --deployment myapp --no-reuse --shards 0) - run noria-mysql from README (
cargo run --release -- --deployment myapp -z 127.0.0.1:2181) - execute
mysql -h 127.0.0.1 - create table and insert data in it (
CREATE TABLE Cats (id int, name VARCHAR(255), PRIMARY KEY(id));,INSERT INTO Cats (id, name) VALUES (1, "bob");) - run Java application
Some java app example
main methodClass.forName("com.mysql.cj.jdbc.Driver");
final String name = DriverManager
.getConnection("jdbc:mysql://127.0.0.1/")
.prepareStatement("select * from Cats")
.executeQuery()
.getString("name");
System.out.println(name);

My questions:
- Is they any solution to resolve this error above?
- How to interact with
noria-mysqladapter through the Java code? - What is the general idea of interacting with
noria-mysql? (besidesmysql -h 127.0.0.1nothing is working for me)
