I am using Spring 3.1.x and CXF 2.6.1 for REST services. I using jaxbXmlProvider as shown below.
<jaxrs:server ...
<jaxrs:providers>
<ref bean="jaxbXmlProvider" />
</jaxrs:providers>
...
</jaxrs:server>
<bean id="jaxbXmlProvider" class="org.apache.cxf.jaxrs.provider.JAXBElementProvider">
<property name="jaxbElementClassNames" ref="elements" />
</bean>
<util:list id="elements">
<value>com.model.City</value>
<value>com.model.Cities</value>
</util:list>
I would like to use jaxb2-marshaller for scanning all the POJOS in a package(com.model). Any usage help is appreciated.
You can call a method of another bean that provides the list of classes something like:
<property name="jaxbElementClassNames" value="#{ myBean.classNamesFromPackage}"/>
Configure myBean that takes package name as a property and has getClassNamesFromPackage method:
<bean id="myBean" class="x.y.z.MyBean">
<property name="packageName" value="com.model" />
</bean>
In getClassNamesFromPackage method of MyBean, you can use the code suggested in How do I read all classes from a Java package in the classpath?.

I have been trying for couple days to set up multiple ActiveMQ connections in Spring Integration using XML configuration.
I am using spring boot, SI looks for a bean called jmsConnectionFactory in the context and uses it. But what if I have to send/listen to jms messages from/to different ActiveMQ servers?
What I have right now is this:
<bean id="jmsConnectionFactory1"
class="org.springframework.jms.connection.CachingConnectionFactory">
<property name="targetConnectionFactory">
<bean class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="tcp://localhost:61616" />
</bean>
</property>
<property name="sessionCacheSize" value="10" />
<property name="cacheConsumers" value="false" />
</bean>
<bean id="jmsConnectionFactory2"
class="org.springframework.jms.connection.CachingConnectionFactory">
<property name="targetConnectionFactory">
<bean class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="tcp://192.168.1.59:61616" />
</bean>
</property>
<property name="sessionCacheSize" value="10" />
<property name="cacheConsumers" value="false" />
</bean>
...
<jms:message-driven-channel-adapter channel="jmsInChannel" destination-name="queue.demo" />
<int:channel id="jmsInChannel" />
...
When trying to start the spring boot app I get this error:
***************************
APPLICATION FAILED TO START
***************************
Description:
A component required a bean named 'jmsConnectionFactory' that could not be found.
The following candidates were found but could not be injected:
- Bean method 'jmsConnectionFactory' in 'ActiveMQXAConnectionFactoryConfiguration' not loaded because #ConditionalOnClass did not find required class 'javax.transaction.TransactionManager'
Action:
Consider revisiting the entries above or defining a bean named 'jmsConnectionFactory' in your configuration.
I came across this solution, https://stackoverflow.com/a/43401330/3367392 it's a java configuration. Also I looked into this but it's using camel https://stackoverflow.com/a/13288312/3367392
Is there a way to achieve the same for Spring Integration using XML configuration?
Ok so I got it, for a simple case I just had to add the right connectionFactory to the adapters like this
<jms:message-driven-channel-adapter channel="jmsInChannel"
destination-name="queue.demo"
connection-factory="jmsConnectionFactory1" />
I am new with spring and I still don't know well about hierarchy and terminology of spring. I am implementing a RESTful app with spring. After searching and reading about how to internationalize spring, I tried to do it in my app. But it seems to me it is not configured properly. Because I get exception. I would like to show you the screenshot of my project structure. And I would like to ask you why my applicationContext.xml show a problem exist.
spring-servlet.xml
<!-- SPRING INTERNALIZATION CONFIGURATION -->
<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
<property name="basename" value="classpath:messages" />
<property name="defaultEncoding" value="UTF-8"/>
</bean>
<bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver">
<property name="defaultLocale" value="en"/>
</bean>
<bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
<property name="paramName" value="language" />
</bean>
<bean id="handlerMapping" class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
<property name="interceptors">
<ref bean="localeChangeInterceptor" />
</property>
</bean>
The javadoc of ReloadableResourceBundleMessageSource.setBaseNames() says:
Set an array of basenames, each following the basic ResourceBundle convention of not specifying file extension or language codes, but in contrast to ResourceBundleMessageSource referring to a Spring resource location: e.g. "WEB-INF/messages" for "WEB-INF/messages.properties", "WEB-INF/messages_en.properties", etc.
But you've placed your message properties files under src/main/resources in the Maven project structure, so they will end up at the root of the classpath instead (which means that even if Spring looked for them in the classpath, the /resources prefix you've used in the configuration would prevent Spring to find them).
So place the properties file under WEB-INF, and use WEB-INF/messages as the basenames property.
i want use Websphere work manager for executing async jobs in jee context but i have problem with creating spring WorkManager.
bean definition:
<bean id="taskExecutor" class="org.springframework.scheduling.commonj.WorkManagerTaskExecutor"> <property name="workManagerName" value="wm/default" /> </bean>
this definition i found in websphere help. But problem is this ends with noClassDefFound. I noticed pckg org.springframework.scheduling.commonj is missing from spring-context since version 2.x.x
Is it replaced with org.springframework.jca.work.WorkManagerTaskExecutor ?
when i use this other spring class, i get error:
Caused by: org.springframework.jndi.TypeMismatchNamingException:
Object of type [class com.ibm.ws.asynchbeans.WorkManagerImpl]
available at JNDI location [wm/default] is not assignable to
[javax.resource.spi.work.WorkManager]
so whats deal here? thx
was - 7.0.0.23
spring - 3.1.2
Class org.springframework.scheduling.commonj.WorkManagerTaskExecutor resides in spring-context-support-3.1.2.RELEASE.jar
Configuration succeeds with javax.resource.spi.work.WorkManager in applicationContext-service.xml in deployment.....
In my case deployment fails for bean injection org.springframework.scheduling.commonj.WorkManagerTaskExecutor as it fails to take WorkManager JNDI Configured in Application Server.... I just replaced javax.resource.spi.work.WorkManager. And so far it is success deployment.
I yet to see application works fine with it.
<bean id="taskExecutor" class="javax.resource.spi.work.WorkManager">
<property name="workManagerName" value="wm/default" />
</bean>
In our scenario we were managed it by ThreadPoolTaskExecutor instead of WorkManagerTaskExecutor
Here is configuration that comes in ApplicationContext.xml
<!--
<bean id="rtSenderTaskExecutor"
class="org.springframework.scheduling.commonj.WorkManagerTaskExecutor">
<property name="workManagerName">
<value>${org.quartz.threadPool.jndi}</value>
</property>
</bean> -->
<!-- Local Thread Pool -->
<bean id="rtSenderTaskExecutor"
class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">
<property name="corePoolSize" value="${org.quartz.threadPool.corePoolSize}" />
<property name="maxPoolSize" value="${org.quartz.threadPool.maxPoolSize}" />
<property name="queueCapacity" value="${org.quartz.threadPool.queueCapacity}" />
<property name="keepAliveSeconds" value="${org.quartz.threadPool.keepAliveSeconds}"></property>
</bean>
Background
We are using Apache CXF 2.5.x , JSR 311 1.1.1 , and Spring 2.5.x
We currently have 2 endpoints, ABC and DEF, that use Jackson as the JSON provider. Our Spring file looks something like:
<bean id="jacksonMapper" class="org.codehaus.jackson.map.ObjectMapper" />
<bean id="jsonProvider"class="org.codehaus.jackson.jaxrs.JacksonJsonProvider" p:mapper-ref="jacksonMapper"/>
<jaxrs:server id="service1" address="/">
<jaxrs:serviceBeans>
<ref bean="resourceABC" />
<ref bean="resourceDEF" />
</jaxrs:serviceBeans>
<jaxrs:providers >
<ref bean="jsonProvider"/>
</jaxrs:providers>
</jaxrs:server>
Using annotations on the Java classes, these endpoints are available via http://company.com/api/rest/ABC and http://company.com/api/rest/DEF
Challenge
We want to introduce a new endpoint, IJK, that uses Gson as a JSON provider. We would like the endpoint to map to http://company.com/api/rest/IJK.
Note: Indeed, it is trivially easy to map to http://company.com/api/rest/new/IJK by using a different endpoint, but we'd like to avoid that.
Approaches
We've tried defining a new server with the same address:
<jaxrs:server id="service2" address="/">
<jaxrs:serviceBeans>
<ref bean="resourceIJK" />
</jaxrs:serviceBeans>
<jaxrs:providers >
<ref bean="gsonProvider"/>
</jaxrs:providers>
</jaxrs:server>
but that doesn't work. We've tried using multiple providers in the same server element, but no dice.
This link discusses using serverFactories elements. Such as:
<beans>
<jaxrs:server id="customerService" address="/service1">
<jaxrs:serviceFactories>
<ref bean="sfactory1" />
<ref bean="sfactory2" />
</jaxrs:serviceFactories>
</jaxrs:server>
<bean id="sfactory1" class="org.apache.cxf.jaxrs.spring.SpringResourceFactory">
<property name="beanId" value="customerBean1"/>
</bean>
<bean id="sfactory2" class="org.apache.cxf.jaxrs.spring.SpringResourceFactory">
<property name="beanId" value="customerBean2"/>
</bean>
<bean id="customerBean1" class="demo.jaxrs.server.CustomerRootResource1" scope="prototype"/>
<bean id="customerBean2" class="demo.jaxrs.server.CustomerRootResource2" scope="prototype"/>
</beans>
This looks promising, but how to set the JSON provider for the services, customerBean1 and customerBean2 in Spring?
Question
Can someone clarify the last approach above, with serviceFactories? Can we achieve the goal of introducing resourceIJK (at the same endpoint root) with Gson instead of Jackson?
If it can be done only with Apache CXF 2.7, that is OK and useful info.
Environment: Windows server 2003, Spring 3.0, Tomcat 6
How can I reference a JNDI property inside a PropertyPlaceholderConfigurer?
Specifically, I'm using JNDI to look up a java.lang.String that represents a path to
a property file needed by my webapp
<jee:jndi-lookup id="mypropsfile1" jndi-name="myPropsFile1" resource-ref="true"/>
<jee:jndi-lookup id="mypropsfile2" jndi-name="myPropsFile2" resource-ref="true"/>
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="ignoreUnresolvablePlaceholders" value="true"/>
<property name="locations">
<array>
<value>how to use mypropsfile1 here ??</value>
<value>how to use mypropsfile2 here ??</value>
</array>
</property>
</bean>
My "jee:jndi-lookup"s are working AFAIK. My problem seems to be how to reference JNDI resources
inside the tag pair
Thanks in advance!
Mark
Your approach may not work Mark, this is because PropertyPlaceHolderConfigurer is a BeanFactoryPostProcessor and gets invoked at the point when the bean definitions are created, whereas the jndi lookup happens post this stage.
I saw an older Spring forum discussion item, which has a recommendation for an approach of using a jndi lookup based properties file, which may suit your needs:
I believe you will have to do something like this . I haven't tested it but basically the setLocations method in PropertyPlaceholderConfigurer takes in an array of Resource(In our case UrlResource - http://static.springsource.org/spring/docs/2.0.x/api/org/springframework/core/io/UrlResource.html) which in turn has a constructor with the file path .
<jee:jndi-lookup id="mypropsfile1" jndi-name="myPropsFile1" default-value="file:///C:/defaultPath" resource-ref="true"/>
<jee:jndi-lookup id="mypropsfile2" jndi-name="myPropsFile2" resource-ref="true"/>
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" depends-on="mypropsfile1,mypropsfile2">
<property name="ignoreUnresolvablePlaceholders" value="true"/>
<property name="locations">
<list>
<bean class="org.springframework.core.io.UrlResource">
<constructor-arg><ref bean="mypropsfile1"/></constructor-arg>
</bean>
<bean class="org.springframework.core.io.UrlResource">
<constructor-arg><ref bean="myPropsFile2"/></constructor-arg>
</bean>
</list>
</property>
</bean>
I am not sure if there is a tag called in spring . Check this http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/beans.html#beans-introduction
I do this in Spring 3 using a map as follows:
<jee:jndi-lookup id="myJndiLookup" jndi-name="com.techtrip.spring.config.myJndiLookup"></jee:jndi-lookup>
<bean id="somethingWithMap" class="com.techtrip.foo.SomethingWithMap">
<property name="propMap">
<map>
<entry key="myJndiLookup" value-ref="myJndiLookup" />
</map>
</property>
</bean>
This works fine in most cases. You may run into trouble if you use AOP or something that wraps the bean in a Proxy class even if you set eager init correctly. A solution in that case is to directly access the somethingWithMap bean from the app context when needed using:
applicationContext.getBeansOfType(type, includeNonSingletons, allowEagerInit);
*Note that this will return a Map<String, T> where you can access the bean by name.
Not exactly for a single JNDI property, this is using a Properties reference instead, obtained through JNDI:
<!-- Lookup Properties reference through JNDI -->
<jee:jndi-lookup id="config-properties" jndi-name="resources/resource-name" resource-ref="true"/>
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" depends-on="config-properties">
<property name="ignoreUnresolvablePlaceholders" value="true"/>
<!-- Once the reference is obtained from JNDI, it can be used like any other reference -->
<property name="properties" ref="config-properties"></property>
</bean>
