I have a simple Spring Boot application connecting to MySQL database. I need to connect over SSL with certificate.
I know I need a keystore with certificate. I don't know how to configure Liquibase to establish secured connection using that certificate. Can you point me to some documentation, please?
you can try this connection string:
url: jdbc:mysql://<DB_IP>:3306/mytest?allowPublicKeyRetrieval=true&useSSL=true&serverTimezone=UTC&verifyServerCertificate=false&requireSSL=true&clientCertificateKeyStoreUrl=file:/etc/mysqlcerts/keystore_jdbc.jks&clientCertificateKeyStorePassword=<keystore_passwd>&trustCertificateKeyStoreUrl=file:/etc/mysqlcerts/truststore.jks&trustCertificateKeyStorePassword=<keystore_passwd>
I'm new to Axon framework. I'm evaluating it with Axon Server.
Using Spring Boot is very convenient und worked right away.
Problem is, we are aiming at using Spring Boot processes tied together with non Spring Boot processes (Hybris Commerce from SAP).
My question is: What do I have to do to configure Axon framework 4.2 without Spring Boot? (Without Spring Boot the AxonServerAutoConfiguration does not work).
Thanks in advance!
Axon provides the Configuration API, which as been given its own module as of release 4.
This package contains the Configurer, AggregateConfigurer, EventProcessingConfigurer and SagaConfigurer which should give you all the handles to define any set up with buses, aggregates and query models.
The Reference Guide typically provides snippets on how to configure a given component, both through the Configuration API and Spring Boot as separate code tabs.
Additionally, it's sensible that the AxonServerAutoConfiguration does not work without Spring Boot, as it's a Spring Boot dedicated solution to configuring your application.
Even without it though, Axon will (through a Service Loader mechanism) auto-load the ServerConnectorConfigurerModule once you've created a default Configurer. This should give you the required infrastructure components to configure an application using Axon Server without utilizing Spring Boot.
I have a spring boot application which is using mySQL db.DB is accessible on ssh via a different server.In Mysql Workbench i have created tunnel to access the mysql DB.
Now my question is there any way that i can do the same(tunnel over ssh) in my spring boot application? I have already searched on google but didn't get any fix for it.
If anyone can give an idea how to implement that would be really helpful.
Regards,
Assuming that you are on a UNIX/Linux platform, the idea is that you do a
ssh -L 3306:mysql-server:3306 username#mysql-server
From within you spring boot application, you do a connect to localhost:3306 which is forwarded to the mysql-server on port 3306.
Doing it directly inside spring boot, you should go with Java Secure Channel. An example for port forwarding is described here.
my school projekt task is to develop Issue tracking System. My imagine:
JavaFX desktop client application + Spring 4 server + MYSQL database
I would like to use JDBC to reach datas. How should I do it? Spring server made the queries and after it, the spring server should send the client the serialized data?
Yes it's possible, though you don't need spring in that scenario.
Jdbc client would connect directly to the database over the network.
You would have to expose your database to public tcp connections, and firewalls would have to allow this too.
Other options:
Use a local database, like sqlite , and sync w central db over https using a tool like symmetricds. This gives you offline capabilty.
create a restful api on the server, and have the client get and set data using http.
I read in c3p0´s manual link that it is possible to use c3p0 library inside JBOSS as an MBean.
Once configured correctly, I would like to reference the new C3P0PooledDataSource in my Java WAR through its JNDI name. As I am using Spring
it would be something similar to:
[src/webapp/WEB-INF/applicationContext.xml]
<jee:jndi-lookup id="dataSource" jndi-name="java:PooledDS" />
However, I don´t know how to configure this library properly. I tried to place c3p0-0.9.2.1.jar and c3p0-service.xml in the folders commented in the manual
but I had no luck.
I am currently developing a project which uses a MySql database, so I have instaled the mysql connector inside the JBOSS AS 7.1.1 server.
I have to say that if I integrate c3p0 and MySql connector in my project I can deploy it correctly. So...:
Is it possible to use c3p0 connection pool inside JBOSS AS 7.1.1 as described in its manual? How should I configure it?
I started to "play" with c3p0 because of its large number of configuration properties, but I don´t know if c3p0 is better than embedded JBOSS pooling capabilities.
Does c3p0 library deserve to be used instead of JBOSS embedded connection pool (i.e. configuring a datasource with the admin console/web) ?
I appreciate any comments to these matters.
Thanks in advance.
