带有数据源的 Wildfly 配置

Question

this is the first time I am trying to setup datasource in my Wildfly server. I tried to follow some tutorials which I found on Google but it still doesn't work.

I am working on a web service but I keep getting some errors when I deploy my .war file.

Here is the latest log when app is deployed:

Just tell me if you need more files.

Answer 1

Go into your wildfly console (something like localhost:9990) and edit the Configuration->Container->EE->Default Bindings section. Set the default datasource to the JNDI name of some valid datasource.

I removed the default one that was there and just pointed it to my main datasource since the server exists to run one app only.

Answer 2

You probably have the ds declaration "java:jboss/datasources/ExampleDS" missing in your standalone.xml xmlns "urn:jboss:domain:datasources:2.0" section, just and it will work (here's the example from the default configuration):

            <datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true">
                <connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE</connection-url>
                <driver>h2</driver>
                <security>
                    <user-name>sa</user-name>
                    <password>sa</password>
                </security>
            </datasource>
            <drivers>
                <driver name="h2" module="com.h2database.h2">
                    <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
                </driver>
            </drivers>

Or you can also add through the UI as mentioned by other response.

Answer 3

can you post your datasource definition?

I think it would be the best to test the datasource deployment 'standalone'. I mean separated from an actual application deployment, just to test whether your datasource works or not. You can test this fi using the web console (localhost:9990/console).

It also looks like there are problems with the pre-configured example DS of wildfly. Did you remove this DS? In standalone.xml there is also a reference on ExampleDS which might be broken.

Answer 4

Assuming you are using a MySQL DB, you can create a DS in the following way:

(1) Download the mysql driver from here: http://dev.mysql.com/downloads/connector/j/

(2) Copy the mysql driver to: WILDFLY_HOME/modules/system/layers/base/com/mysql/main

(3) From the JBoss (or Wildfly) console, run the command:

/subsystem=datasources/jdbc-driver=mysql:add(driver-name=mysql, driver-module-name=com.mysql, driver-class-name=com.mysql.jdbc.Driver)

(4) Then, again from the JBoss (or Wildfly) console, run command:

/subsystem=datasources/data-source=YourDS:add(driver-name=mysql, user-name=USERNAME, password=PASSWORD, connection-url=jdbc:mysql://localhost:3306/YOURDATABASE, min-pool-size=5, max-pool-size=15, jndi-name=java:jboss/datasources/YourDS, enabled=true, validate-on-match=true, valid-connection-checker-class-name=org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLValidConnectionChecker, exception-sorter-class-name=org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLExceptionSorter)

Voila. Now you have a Datasource with a JNDI path of: java:jboss/datasources/YourDS

检查默认绑定配置是否引用了正确的数据源： https : //docs.jboss.org/author/display/WFLY8/Default+EE+Bindings+Configuration

Answer 6

I had

service jboss.naming.context.java.jboss.datasourservice jboss.naming.context.java.jboss.datasources.ExampleDS (missing) dependents:...

on wildfly-8.1.0.Final.

IMHO

in standalone/configuration/standalone-full.xml it had

<default-bindings ... datasource="java:jboss/datasources/ExampleDS" ...

and

<datasource jndi-name="java:/datasources/ExampleDS"...

jndi-name mismatch!

I created ExampleDS2 with jndi-name="java:jboss/datasources/ExampleDS". This solved my problem.
