ResourceAdapter
public class SpringContextResourceAdapter extends Object implements ResourceAdapter
JCA 1.5ResourceAdapter
implementation that loads a SpringApplicationContext
, starting and stopping Spring-managed beans as part of the ResourceAdapter's lifecycle.Ideal for application contexts that do not need any HTTP entry points but rather just consist of message endpoints and scheduled jobs etc. Beans in such a context may use application server resources such as the JTA transaction manager and JNDI-bound JDBC DataSources and JMS ConnectionFactory instances, and may also register with the platform's JMX server - all through Spring's standard transaction management and JNDI and JMX support facilities.
If the need for scheduling asynchronous work arises, consider using Spring's
WorkManagerTaskExecutor
as a standard bean definition, to be injected into application beans through dependency injection. This WorkManagerTaskExecutor will automatically use the JCA WorkManager from the BootstrapContext that has been provided to this ResourceAdapter.The JCA
BootstrapContext
may also be accessed directly, through application components that implement theBootstrapContextAware
interface. When deployed using this ResourceAdapter, the BootstrapContext is guaranteed to be passed on to such components.This ResourceAdapter is to be defined in a "META-INF/ra.xml" file within a J2EE ".rar" deployment unit like as follows:
<?xml version="1.0" encoding="UTF-8"?> <connector xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee https://java.sun.com/xml/ns/j2ee/connector_1_5.xsd" version="1.5"> <vendor-name>Spring Framework</vendor-name> <eis-type>Spring Connector</eis-type> <resourceadapter-version>1.0</resourceadapter-version> <resourceadapter> <resourceadapter-class>org.springframework.jca.context.SpringContextResourceAdapter</resourceadapter-class> <config-property> <config-property-name>ContextConfigLocation</config-property-name> <config-property-type>java.lang.String</config-property-type> <config-property-value>META-INF/applicationContext.xml</config-property-value> </config-property> </resourceadapter> </connector>
Note that "META-INF/applicationContext.xml" is the default context config location, so it doesn't have to specified unless you intend to specify different/additional config files. So in the default case, you may remove the entireconfig-property
section above.For simple deployment needs, all you need to do is the following: Package all application classes into a RAR file (which is just a standard JAR file with a different file extension), add all required library jars into the root of the RAR archive, add a "META-INF/ra.xml" deployment descriptor as shown above as well as the corresponding Spring XML bean definition file(s) (typically "META-INF/applicationContext.xml"), and drop the resulting RAR file into your application server's deployment directory!

setContextConfigLocation
public void setContextConfigLocation(String contextConfigLocation)
Set the location of the context configuration files, within the resource adapter's deployment unit. This can be a delimited String that consists of multiple resource location, separated by commas, semicolons, whitespace, or line breaks.This can be specified as "ContextConfigLocation" config property in the
ra.xml
deployment descriptor.The default is "classpath:META-INF/applicationContext.xml".
getContextConfigLocation
protected String getContextConfigLocation()
Return the specified context configuration files.
createEnvironment
protected ConfigurableEnvironment createEnvironment()
Return a newStandardEnvironment
.Subclasses may override this method in order to supply a custom
ConfigurableEnvironment
implementation.
start
public void start(BootstrapContext bootstrapContext) throws ResourceAdapterInternalException
This implementation loads a Spring ApplicationContext through thecreateApplicationContext(javax.resource.spi.BootstrapContext)
template method.- 指定者:
start
在接口中ResourceAdapter
- 抛出:
ResourceAdapterInternalException
createApplicationContext
protected ConfigurableApplicationContext createApplicationContext(BootstrapContext bootstrapContext)
Build a Spring ApplicationContext for the given JCA BootstrapContext.The default implementation builds a
ResourceAdapterApplicationContext
and delegates toloadBeanDefinitions(org.springframework.beans.factory.support.BeanDefinitionRegistry, java.lang.String[])
for actually parsing the specified configuration files.- 参数:
bootstrapContext
- this ResourceAdapter's BootstrapContext- 返回:
- the Spring ApplicationContext instance
loadBeanDefinitions
protected void loadBeanDefinitions(BeanDefinitionRegistry registry, String[] configLocations)
Load the bean definitions into the given registry, based on the specified configuration files.- 参数:
registry
- the registry to load intoconfigLocations
- the parsed config locations- 另请参阅:
setContextConfigLocation(java.lang.String)
stop
public void stop()
This implementation closes the Spring ApplicationContext.- 指定者:
stop
