How to bind a Data Source? - java

I'm getting an error -
org.springframework.beans.factory.BeanCreationException: Error creating bean
with name 'netLogsDao': Injection of resource dependencies failed; nested
exception is org.springframework.beans.factory.BeanCreationException: Error
creating bean with name 'abcDataSource' defined in
com.kinsale.submclrmgr.config.DataConfig: Bean instantiation via factory
method failed; nested exception is
org.springframework.beans.BeanInstantiationException: Failed to instantiate
[javax.sql.DataSource]: Factory method 'abcDataSource' threw exception;
nested exception is
org.springframework.jdbc.datasource.lookup.DataSourceLookupFailureException:
Failed to look up JNDI DataSource with name 'dataSource/abc'; nested
exception is javax.naming.NameNotFoundException: Name [dataSource/abc] is
not bound in this Context. Unable to find [dataSource].
I am trying to figure out how to bind my data source, however the documentation I've found isn't helpful. there is a JndiTemplate that I can use to bind the data source, passing the parameters of String name and Object object, but nothing I can find tells me anything about the object.
What is the object that I bind to the name of the data source? And is it the name of the Bean I am creating or the name of the Resource in the context.xml?
Here is the Bean -
#Bean(name="abcDataSource")
public DataSource abcDataSource(){
JndiDataSourceLookup jndi = new JndiDataSourceLookup();
jndi.setResourceRef(true);
return jndi.getDataSource("dataSource/abc");
Here is the use of the bean -
#Resource(name="abcDataSource")
private DataSource ds;
Here is the context.xml entry (I do have the correct username and password)-
<Resource
name="dataSource/abc"
auth="Container"
type="com.mysql.jdbc.jdbc2.optional.MysqlDataSource"
factory="org.apache.naming.factory.BeanFactory"
URL="jdbc:mysql://abc/db_netlogs" />

In order for this to work, the following dependency needs to be in the pom.
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.17</version>
</dependency>
As soon as I added that, everything worked.

Disable #SqsListener for local environment

I have the following value configured in my SQS Listener in springboot. The queue is configured only for DEV and STAGE environments. So I want to disable it in my local after testing. How do i achieve that?
#SqsListener(value = { "${cloud.aws.endpoint}" } , deletionPolicy =SqsMessageDeletionPolicy.ON_SUCCESS)
public void processMessage(String message) throws Exception {
}
I tried to add the following to my application-local.xml(to keep it local), but it didn't work. Anyone went through the same scenario?
autoconfigure:
exclude:
- org.springframework.cloud.aws.autoconfigure.messaging.MessagingAutoConfiguration
- org.springframework.cloud.aws.autoconfigure.context.ContextStackAutoConfiguration
- org.springframework.cloud.aws.autoconfigure.context.ContextRegionProviderAutoConfiguration
I am getting the following error everytime.

I've faced similar issues while using #SqsListener. What I usually do is comment out the annotation when running the app locally - it's ugly but it works.

Instantiating a cxf service causes injection failure for other unrelated service

I am developing a Consumer Service for some Webservice.
The application is already providing Webservices (as a server), but this is the first consumer.
The generation is ok, but I encounter a weird -to me!- problem as soon as I try to instantiate the javax.xml.ws.Service from the constructor of a consumer service : all provider webservices implementor bean become suddenly "undefined" (if I comment the first provider from cxf.xml, the second one is also 'undefined' as well).
Looks like I trigger some unexpected injection that may happen too soon... but I don't understand why, and how to fix it! Any idea is welcome!

public final static URL WSDL_LOCATION;
public final static QName SERVICE = new QName("urn:test.com:anywhere/webservice/T", "SomeService");
static {
URL url = null;
try {
url = new URL("http://some.wsdl");
} catch (MalformedURLException e) {
System.err.println("Ooops! ");
}
WSDL_LOCATION = url;
}
public SomeConsumerService () {
super(WSDL_LOCATION, SERVICE);
}
}
The Context :
<bean name="someService" class="com.my.services.impl.SomeServiceImpl">
</bean>
<bean name="someProviderWebServiceImplementor" class="com.my.services.impl.SomeProviderWebServiceImplementorImpl">
</bean>
A workmate managed to find out the problem : looks like the cxf servlet will create its own context based on cxf.xml (only!) when it is present. If it is not, it will look for its configuration in application Context.
Though, it also it is only true when I create a consumer... thus, I am not sure whether it is more of an unexpected side-effect, or a true feature.
Anyway, the solution that works here is :
rename cxf.xml to another_name_for_cxf.xml
import the renamed file from application-context.xml (or whatever name you gave it)
<import resource="classpath:another_name_for_cxf.xml"/>
And then, the magic will start to operate!

Spring Boot and Teradata UnsatisfiedDependencyException

I am trying to create a simple Spring application with Teradata database.
It was working with mySql database and driver but after changing to Teradata driver/databased i receive following exception :
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Tomcat.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.tomcat.jdbc.pool.DataSource]: Factory method 'dataSource' threw exception; nested exception is java.lang.IllegalArgumentException: URL must start with 'jdbc'
Application Properties :
spring.datasource.url =jdbc:teradata://servername/db
spring.datasource.username = dbc
spring.datasource.password = dbc
spring.datasource.driverClassName=com.ncr.teradata.TeraDriver
I think that is problem of Spring you might be using #Autowire on constructor but spring can't inject class with that name. To solve the problem, just define a DataSource in your context - at which point Spring will be able to inject the bean and correctly bootstrap the context.

Elasticsearch Shield throws CreationException

I'm trying to set up a running service which uses Elasticsearch with Shield. However when I try to start the service I get the following error:
org.springframework.beans.factory.BeanCreationException:

(Sorry for the ugly formatting of stacktrace, feel free to edit for readability)
If I remove the Maven dependency for Elasticsearch Shield then the service starts as expected, without stacktraces, but obviously won't be able to execute any queries because of the exclusion of Shield.
Any help or input at all would be very appreciated.
Edit: I realized that the error is thrown by the Java client, not Elastic itself.

SpringMVC validation : No property 'commandClass' found

I'm trying to implement validation in a springmvc app, I followed the example described at
http://maestric.com/doc/java/spring/form_validation
When I run the app, I get the following error :
org.springframework.beans.factory.BeanCreationException:
Error creating bean with name
'beanNameUrlHandlerMapping' defined in
ServletContext resource
[/WEB-INF/dispatcher-servlet.xml]:
Initialization of bean failed; nested
exception is
org.springframework.beans.factory.BeanCreationException:
Error creating bean with name
'/update.html' defined in
ServletContext resource
[/WEB-INF/dispatcher-servlet.xml]:
Initialization of bean failed; nested
exception is
org.springframework.beans.InvalidPropertyException:
Invalid property 'commandClass' of
bean class
[training.springmvc.crud.controller.UpdatePersonController]:
No property 'commandClass' found
Anyone has an idea?
It looks like the bean declaration for /update.html is trying to set the value of a non-existent property called commandClass on an instance of your UpdatePersonController class.
(If you showed us the relevant code and XML wiring files we could confirm this.)
