I want an interceptor to be called for all the url's with pattern /user/display/* and don't want to configure the controller name to which these url's map to.
Spring documentation gives the following example
<bean id="handlerMapping"
class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="interceptors">
<list>
<ref bean="officeHoursInterceptor"/>
</list>
</property>
<property name="mappings">
<value>
/user/display/*=editAccountFormController
</value>
</property>
</bean>
In my case i don't want to give editAccountFormController.
Is it possible to do that?
You can specify interceptors independently of the controllers using <mvc:interceptors>, e.g.
<mvc:interceptors>
<mvc:interceptor>
<mapping path="/user/display/*"/>
<bean class="com.x.y.MyInterceptor" />
</mvc:interceptor>
</mvc:interceptors>
See docs for more detail.

We used to have the following configuration to customize our message converters in Spring 4:
<mvc:annotation-driven conversion-service="conversionService" content-negotiation-manager="contentNegotiationManager">
<mvc:message-converters>
<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="objectMapper" ref="myObjectMapper"/>
</bean>
</mvc:message-converters>
</mvc:annotation-driven>
But after migrating to Spring 5, the above configuration has lost any effect (the default message converters take place).
If I define the bean explicitly, it works:
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
<property name="messageConverters">
<list>
<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="objectMapper">
<bean class="org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean">
<property name="objectMapper" ref="myObjectMapper" />
</bean>
</property>
</bean>
<bean class="org.springframework.http.converter.ByteArrayHttannotation-drivenpMessageConverter"/>
<bean class="org.springframework.http.converter.xml.SourceHttpMessageConverter"/>
<bean class="org.springframework.http.converter.FormHttpMessageConverter"/>
<bean class="org.springframework.http.converter.StringHttpMessageConverter" />
</list>
</property>
</bean>
Any idea why the mvc:message-converters tag stopped working?
ps. While debugging the issue I also noticed several instances of RequestMappingHandlerAdapter being instantiated in all cases, even though I would expect them to be a singleton. The latter significantly obscures debugging, since I'm not sure which is the right one to attribute message converters to to investigate.
pps. Another report of this issue:
https://stackoverflow.com/a/49156186/657723
In this case mvc:message-converters was overridden by another, empty mvc:annotation-driven which happened to be unnoticeably included down the chain of child xml inclusions.
In any case, the major problem was the silent override, which should have better be an error.
In most cases, I'm able to replace MultiActionController with an annotated controller just fine. But I have a use-case where I need to map different URLs to DIFFERENT instances of the same controller class, each wired with a different implementation of the same interface. (It's for various find-as-you-type APIs.) I've been using SimpleUrlHandlerMapping for this. Is there any way to do this with an annotated controller? Or do I now have to make separate controller classes for each API? Here's my config with only two MultiActionControllers shown, although I have more:
<bean name="regionAutocompleteController" class="...ajax.autocomplete.AutocompleteController" autowire="byName">
<property name="finder" ref="regionFinder"/>
</bean>
<bean name="blockAutocompleteController" class="...ajax.autocomplete.AutocompleteController" autowire="byName">
<property name="finder" ref="blockFinder"/>
</bean>
<bean id="atlasAjaxControllerMappings"
class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="order" value="4" />
<property name="mappings">
<props>
<prop key="/findBlock/*">blockAutocompleteController</prop>
<prop key="/findRegion/*">regionAutocompleteController</prop>
</props>
</property>
</bean>
I am new on Spring batch so am here to ask some basic advice.
What is the best approach to load a config file in memory (or bean) and use its content while the spring Job/step are running ?
I am not sure but based on some google search I found the below scenario even if I dont quite understand why I should define a writer even if i dont need it :
step1 : load config file (the content is two field delimited by =)
step2 : perform some java code and use the previous config file
so for the step 1 :
<bean id="inputFile" class="org.springframework.core.io.FileSystemResource" scope="step">
<constructor-arg value="path_config_file"/>
</bean>
<bean id="readerConfigFile" class="org.springframework.batch.item.file.FlatFileItemReader" scope="step">
<property name="resource" ref="inputFile"/>
<property name="lineMapper">
<bean class="org.springframework.batch.item.file.mapping.DefaultLineMapper">
<property name="lineTokenizer">
<bean class="org.springframework.batch.item.file.transform.DelimitedLineTokenizer">
<property name="names" value="field,value"/>
<property name="delimiter" value="="/>
</bean>
</property>
<property name="fieldSetMapper">
<bean class="org.springframework.batch.item.file.mapping.BeanWrapperFieldSetMapper">
<property name="prototypeBeanName" value="configProperties"/>
</bean>
</property>
</bean>
</property>
</bean>
<bean id="outputConfig" class="outputConfig"></bean>
<bean id="configProperties" class="configProperties" scope="prototype"/>
so my question are :
How can I use the information gathered in the file ? Should I put them in the Java bean ?
How can I pas this info between different step or make them persistent in the whole application life-cycle ?
Would you recommend to use a itemProcessor to achieve the above ?
Any advice are most than welcome
I'm a bit confused about your questions because I think you only need to load a properties file in spring context using a PropertiesFactoryBean:
<bean id="config" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
<property name="location">
<value>file:path_config_file</value>
</property>
</bean>
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="propertiesArray">
<list>
<ref bean="config"/>
</list>
</property>
</bean>
and you can refer to property values using ${} placeholder; but this solution is unrelated to spring-batch; I don't need it!
About your questions:
Using a POJO is a good way because spring-batch offers in-box mapping strategies (BeanWrapperFieldSetMapper in your case)
Objects used in a job are accessible only in job context, not in application context (this is why I think you need a PropertiesFactoryBean).To pass object between steps read How can we share data between the different steps of a Job in Spring Batch?
ItemProcessor is requested if you need to convert an object T read from a ItemReader<T> to an object of type S written by an ItemWriter<S>. So no, you don't need an ItemProcessor.

We are migrating our web application from Spring 2.5 to Spring 3.0.5. Looks like all the Controller classes (the classes in org.springframework.web.servlet.mvc package: BaseCommandController, AbstractCommandController, SimpleFormController, etc) have been deprecated. We used those classes heavily in our application. These classes have been replaced by #Controller annotation instead.
I have a few questions regarding Spring 3.0.x Controller configuration...
We used the following XML to create a Controller bean in Spring 2.5. If <context:component-scan> is used instead to create the Controller beans, then how do I wire-in the dependencies? If possible I would like to avoid Auto-Wiring.
<bean id="photosetViewController" class="com.xyz.web.PhotosetViewController"
p:photosetManager-ref="photosetManager"
p:photoManager-ref="photoManager" />
We have created 3 Interceptors. We use SimpleUrlHandlerMapping to map these Interceptors to different request URLs and also to map URLs to Controllers. How do we achieve the same in Spring 3.0.x?
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="alwaysUseFullPath" value="true" />
<property name="interceptors">
<list>
<ref bean="httpRedirectInterceptor"/>
<ref bean="loginInterceptor"/>
</list>
</property>
<property name="mappings">
<value>
/abc.html=abcLookupController
/photoupload.html=photoUploadController
</value>
</property>
</bean>
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="alwaysUseFullPath" value="true" />
<property name="interceptors">
<list>
<ref bean="httpRedirectInterceptor"/>
<ref bean="loginInterceptor"/>
<ref bean="userMenuInterceptor" />
</list>
</property>
<property name="mappings">
<value>
/index.html=homepageController
/success.html=simpleController
</value>
</property>
</bean>
In case of SimpleFormControllers we used different methods like initBinder, referenceData, formBackingObject. We also used command objects and validation classes. How do we achieve the same in Spring 3.0.x?
<bean id="photosetAddController" class="com.xyz.web.PhotosetAddController"
p:photosetManager-ref="photosetManager"
p:photosetTypeManager-ref="photosetTypeManager"
p:stateManager-ref="stateManager" >
<property name="validator">
<bean class="com.xyz.form.PhotosetAddValidator" />
</property>
<property name="formView" value="photosetadd" />
<property name="successView" value="redirect:/photoset" />
</bean>
Any pointers are greatly appreciated.
As skaffman noted - your code will work fine without any modifications. I'll answer your questions in short:
You can use #Resource(name="beanName") for name-based injection. But autowiring is also a good option. Either #Autowired, or #javax.inject.Inject. Note that you can use #Qualifier("name") to differentiate between beans with the same interface/base class. You can even use the javax.inject qualifiers (read about all these in the docs)
interceptor mappings can stay the same
There is #InitBinder, which denotes the initBinder method. I can't tell about the other.
greetings all
i am using velocity templates when sending emails
and i want to read texts dynamically from property files depending on user locale
the xml config:
<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
<property name="basenames">
<list>
<value>classpath:messages</value>
<value>classpath:messages_ar</value>
</list>
</property>
<property name="defaultEncoding" value="UTF-8"/>
</bean>
<bean id="velocityEngine"
class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
<property name="velocityProperties">
<props>
<prop key="resource.loader">class</prop>
<prop key="class.resource.loader.class">org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader</prop>
<prop key="velocimacro.library">org/springframework/web/servlet/view/velocity/spring.vm</prop>
</props>
</property>
</bean>
<bean id="velocityConfig" class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">
<property name="resourceLoaderPath" value="/WEB-INF/classes/com/spacerdv/mailTemplates"/>
</bean>
<!--
View resolvers can also be configured with ResourceBundles or XML files. If you need
different view resolving based on Locale, you have to use the resource bundle resolver.
-->
<bean id="viewResolver" class="org.springframework.web.servlet.view.velocity.VelocityViewResolver">
<property name="cache" value="true"/>
<property name="prefix" value=""/>
<property name="suffix" value=".vm"/>
<!-- if you want to use the Spring Velocity macros, set this property to true -->
<property name="exposeSpringMacroHelpers" value="true"/>
</bean>
and when trying to read the text from property file like :
<span>#springMessage("hi.message")</span>
it doesn't read any thing, or prints the default value, just prints:
$springMacroRequestContext.getMessage($code)
i don't know why? , am i missing something ?, any help ?
When using the velocity engine for sending emails, you may have to configure your engine tu use the velocimacro librabry shipped within spring.
<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
<property name="velocityProperties">
<props>
<prop key="resource.loader">class</prop>
<prop key="class.resource.loader.class">org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader</prop>
<prop key="velocimacro.library">org/springframework/web/servlet/view/velocity/spring.vm</prop>
</props>
</property>
</bean>
You can check the example in spring documentation.
If Spring doesn't inject automatically the $springMacroRequestContext variable into your model, you should put it yourself:
model.put("springMacroRequestContext", new RequestContext(request, response, getServletContext(), model));
That's basically what they do in the AbstractTemplateView class. I guess you won't be able to do it, since you're handling emails here, and not web requests. But that's definitely a hint on what you can do to get it working.
macros can't be used outside web app like in email templates, so a solution would be to pass messageSource to the vm file and read from the property file by it like the answer in here:
Is it possible to read static text dynamically from property files in velocity template?
