I am developing a web application where I wrote a method, in that method I called a json url and parsing that and store in a pojo class.
I just cache this method using methodcacheinterceptor concept, My xml configuration below:
<bean id="methodCacheInterceptor"
class="web.app.services.MethodCacheInterceptor">
<property name="cache">
<ref local="methodCache" />
</property>
</bean>
<bean id="methodCache" class="org.springframework.cache.ehcache.EhCacheFactoryBean">
<property name="cacheManager">
<ref local="cacheManager" />
</property>
<property name="cacheName">
<value>videoItemsCache</value>
</property>
</bean>
<bean id="cacheManager"
class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
<property name="configLocation">
<value>/WEB-INF/ehcache.xml</value>
</property>
</bean>
<bean id="methodCachePointCut"
class="org.springframework.aop.support.RegexpMethodPointcutAdvisor">
<property name="advice">
<ref local="methodCacheInterceptor" />
</property>
<property name="patterns">
<list>
<value>.*web.app.services.ItemCollectionImpl.getCollection</value>
<value>.*web.app.services.ItemCollectionImpl.buildCollection</value>
</list>
</property>
</bean>
I set a time of 20 mins caching & it works perfectly!
All I want is for a particular activity I want to override & clear those cache, For the next time I visit page I want that whole method to be executed and data should not be loaded from cache (I want to clear the cache) for that particular activity.
FYI
CacheManager.getInstance().getCacheNames() - this prints my cachename which I have given in the xml configuration.
I have tried CacheManager.getInstance().clearAll(), removeall methods but it doesn't works!!
Anyone help me here!
Thanks in advance.

Currently I am using JdbcCursorItemReader and FlatFileItemWriter in a job step.
Due to performance issue we have to use stored procedure.
Is there a way to make a call to stored proc in Spring Batch 2.0.. RELEASE?
<bean id="jdbcCursorItemReader" class="org.springframework.batch.item.database.JdbcCursorItemReader">
<property name="dataSource" ref="dataSource"/>
<property name="sql"
value="SELECT X,Y,Z
FROM V_VIEW "/>
<property name="mapper">
<bean class="com.mapping.SomeMapper"/>
</property>
</bean>
<bean class="org.springframework.batch.item.file.FlatFil eItemWriter" id="flatFileItemWriter">
<property name="resource" ref="resource"/>
<property name="fieldSetCreator">
<bean class="org.springframework.batch.item.file.mapping .PassThroughFieldSetMapper"/>
</property>
</bean>

how to write a custom database reader wih callable statement...
Sample code is appreciated.. Thank You,.
There is a StoredProceedureItemReader that is built just for this use case. You can read more about it in the documentation here: https://docs.spring.io/spring-batch/apidocs/org/springframework/batch/item/database/StoredProcedureItemReader.html
I could find my answer:
<bean id="jdbcCursorItemReader" class="org.springframework.batch.item.database.JdbcCursorItemReader">
<property name="dataSource" ref="dataSource"/>
<property name="sql" value="Call schema.StoredProcName"/>
<property name="mapper">
<bean class="com.mapping.SomeMapper"/>
</property>

I am using a data source defined in tomcat in my spring configuration as shown in the below xml.
It can happen sometimes that this data source may not be defined in the context.xml of tomcat.
In such cases , the context initialization fails since myDS is not found.
Is it possible to configure the datasource as optional so that application initialisation is not impacted ?
There can be a run time error when this data source is accessed , which is acceptable
<bean id="myDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:comp/env/jdbc/myDS"/>
</bean>
<bean id="myEntityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="myDataSource" />
<property name="persistenceXmlLocation" value="classpath:META-INF/persistence.xml" />
<property name="packagesToScan" value="com..XX.XX" />
<property name="persistenceUnitName" value="myPU" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="showSql" value="#{systemProperties['showSql'] == null ? 'true' : systemProperties['showSql'] }" />
</bean>
</property>
<property name="persistenceUnitPostProcessors">
<list>
<ref bean="wrkflw-punitpostprocessor" />
</list>
</property>
<property name="jpaProperties">
<props>
<prop key="hibernate.dialect">#{systemProperties['dbDialect']}</prop>
</props>
</property>
</bean>

You may check the DelegatingDataSource, you could encapsulate the logic to load the datasource from JNDI within its instantiation. For your application there will be always a DataSource there, but in some cases (whenever its not able to load the DataSource from JNDI) there is no delegation.
I found this topic How do i exclude everything but text/html from a heritrix crawl?
I have changed bean to this
<property name="shouldProcessRule">
<bean class="org.archive.modules.deciderules.ContentTypeMatchesRegexDecideRule">
<property name="decision" value="ACCEPT" />
<property name="regex" value="^application/pdf.*"/>
</bean>
</property>
</bean>
But heritrix still saves every file to mirror dir.
I believe you are missing a reject rule above your accept rule. I have the following that works:
<property name="shouldProcessRule">
<bean class="org.archive.modules.deciderules.DecideRuleSequence">
<property name="rules">
<list>
<bean class="org.archive.modules.deciderules.RejectDecideRule">
</bean>
<bean class="org.archive.modules.deciderules.ContentTypeMatchesRegexDecideRule">
<property name="decision" value="ACCEPT" />
<property name="regex" value="^application/pdf.*"/>
</bean>
</list>
</property>
</bean>
</property>
This rejects everything, then accepts everything listed in the following rules.
I'm having an issue with using Spring interceptor. I've a CXF service endpoint method which I'm trying a wrap with an interceptor to do some initialization. For some reason, the interceptor is not being invoked. Here's my spring entry:
<jaxrs:server id="acadConnectServer" address="/rest/acadconnect3">
<jaxrs:serviceBeans>
<ref bean="acadConnectResource" />
</jaxrs:serviceBeans>
</jaxrs:server>
<bean id="acadConnectResource"
class="com.test.connectchannel.service.AcadConnectChannelResource" />
<bean id="connectResource" class="org.springframework.aop.framework.ProxyFactoryBean">
<property name="target" ref="acadConnectResource" />
<property name="interceptorNames">
<list>
<value>methodPointCut</value>
</list>
</property>
</bean>
<bean id="methodPointCut"
class="org.springframework.aop.support.NameMatchMethodPointcutAdvisor">
<property name="advice">
<ref local="methodInterceptor" />
</property>
<property name="mappedNames">
<list>
<value>search</value>
<value>searchJSONP</value>
</list>
</property>
</bean>
<bean id="methodInterceptor"
class="com.test.connectchannel.util.ConnectChannelInterceptor">
</bean>
As you can see, I've a CXF endpoint class AcadConnectChannelResource which has couple of methods search and searchJSONp. I've created the Named Method Cut interceptor to intercept these two method calls and so some initialization using the custom intercetor class.But, everytime the methods are invoked, the interceptor is not being called.
Not sure what I'm missing here, any pointer will be appreciated.
-Thanks
I might be entirely wrong, but don't you want
<ref bean="connectResource" />
instead of
<ref bean="acadConnectResource" />
in your <jaxrs:server>? You're proxying the resource, but using the raw resource instead of the proxy.
I have created a JAR that I need to use in my WEB-APP. Both are created with spring framework. I would like to load a .properties file outside the JAR file, in the main context of the web-application. And I want to do it with the facilities that Spring offers us.
I've tried to do something like this in my spring.xml file inside the JAR:
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location">
<value>/WEB-INF/classes/my.properties</value>
</property>
</bean>
<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail" ref="myJob" />
<property name="cronExpression" value="${my.cronExpression}"/>
</bean>
</property>
</bean>
Trying to load my.cronExpression from my.properties file. But without any success.
I always get this error:
Could not resolve placeholder 'my.cronExpression'.
I've tried to change the location with many variants, using classpath:/WEB-INF/classes/my.properties etc...
But I'm not able to load the configuration file.
Thanks for your help.
Use classpath:my.properties - /WEB-INF/classes is root of your classpath.
Try declaring it as follows:
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location">
<value>/WEB-INF/classes/my.properties</value>
</property>
<property name="ignoreUnresolvablePlaceholders">
<value>true</value>
</property>
</bean>
I have gone through your code and want you to try this code snippet
It works well for me :)
<bean id="placeholderProperties"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="file:/WEB-INF/classes/my.properties" />
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
<property name="ignoreUnresolvablePlaceholders" value="true" />
<property name="order" value="1" />
</bean>
