My project use spring mvc and hibernate validator .And I am trying to make it support multi-language.
This is my spring-i18N file
<?xml version="1.0" encoding="UTF-8"?>

<property name="validationMessageSource" ref="messageSource"/>
</bean>
</beans>
And my problem is,while I use annotations in bean file,like this,
#Size(min=6, max=25,message="{password_length_require}")
private String password;
and in the validation_en_US.properties,I do this
password_length_require=The password length require more than 5 and less 25
The result is that page will output "{password_length_require} ".
On the other hand,in my controller,I use
bindingResult.rejectValue("password", "password_length_require");
It will work fine...
Can anybody help me?
I had the same problem before,it took me long time to solve it.
Just like me,there might be something wrong with the following configuration.
<property name="basenames">
<list>
<value>classpath:i18N/messages</value>
<value>classpath:i18N/validation</value>
</list>
</property>
The value of property "basenames" must be full path where your validation messages files save in your project.For example,if validation message files are in package named "org.example.config.i18N.messages", you should config the xml like this:
<value>classpath:org/example/config/i18N/messages</value>
So maybe you need to check whether or not your configuration is right.
The above is my experience, hope to help you.

I have my hibernate entity manager factory declared in jpa.xml, hazecast configured in hazelcast.xml and I have domain model setup and I have corresponding componentContext.xml present in the domain model project where my entity manager factory class is implemented in it. But the problem I am
facing is that my bean in componentContext.xml is getting intialized in a loop (observed from hibernate.log)
My Web.xml has only com.sun.faces.config.ConfigureListener listenere configured.

I have tried debugging multiple times but I am not able to figure out why the initialzing is happening multiple times (as if in a loop). Any pointers greatly appreciated!
I finally figured out the reason! There was an additional #ComponentScan annotation specified in the application configuration class which was causing the loop to be triggered.
Having spent days trying to get my head around AOP, I have no option than to lay out my code and hope the good guys on the internet will help me.

Please help me figure out setting up Shiro annotations. Thank you.
Shiro has a Spring Boot example that uses Shiro's annotations on a controller. And a non-boot example too
I would like my Spring Webflow app to render its views using XSLT. I managed to get a pure Spring MVC app to render with xslt by configuring an XSLTviewresolver and a controller method that returned an already prepared xml as a source.
But I'm not sure how to apply that to the webflow app.
I've added the configuration for the XSLT view resolver and set the view state to the xsl, then I call the controller method that returns the xml source in the on-render of the view state.So far I only get the xsl back as the output and not the transformed xml or even the raw xml.

please help!
Your entity manager bean is called enetityManagerOne, but the variable is called entityManager. Maybe renamme your bean in your XML file:
<bean id="entityManager" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
Another solution could be you forgot the following bean declarations:
For the support for transaction:
<tx:annotation-driven/>
The support for parsing JPA annotations:
<bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"/>
my application context was not on the correct place (src/main/resources). Now I put that there and its working.
Use this code in your dispatcher-servlet.xml
<bean id="persistenceUnitManager" class="org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager">
<property name="persistenceXmlLocations">
<list>
<value>classpath*:META-INF/persistence.xml</value>
</list>
</property>
<property name="defaultDataSource" ref="dataSource"/>
</bean>
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">

<property name="persistenceUnitName" value="etray"/>

it resolve my problem, hope it will help.
I'm trying to use a custom argument inside a method annotated with the ExceptionHandler in spring mvc 3.2 to handle an exception.
However I still get this exception when the method is executed:
java.lang.IllegalStateException: No suitable resolver for argument[1] [type=com.example.domain.CustomArgument]
The Controller method looks like:
#ExceptionHandler(IOException.class)
#ResponseBody
public Error handleIOException(IOException ex, CustomArgument customArgument) {
return new Error(customArgument.getMessage());
}
And I'm using the following xml config:
<mvc:annotation-driven>
<mvc:argument-resolvers>
<bean class="com.example.spring.CustomArgumentWebArgumentResolver" scope="singleton">
<constructor-arg ref="customArgumentService" />
</bean>
</mvc:argument-resolvers>
</mvc:annotation-driven>
<bean id="customArgumentService" class="com.example.service.CustomArgumentService" scope="singleton" />
<bean class="org.springframework.web.servlet.mvc.method.annotation.ExceptionHandlerExceptionResolver" scope="singleton">
<property name="customArgumentResolvers">
<list>
<bean class="com.example.service.CustomArgumentService" scope="singleton">
<constructor-arg ref="customArgumentService" />
</bean>
</list>
</property>
</bean>
<bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver" scope="singleton">
<property name="defaultErrorView" value="forward:/error" />
</bean>
And I believe mvc:annotation-driven is already assigning a ExceptionHandlerExceptionResolver, so how can I add the customArgumentResolver to that.
Any help would be greatly appreciated.
For several ExceptionResolvers try using HandlerExceptionResolverComposite. Something like this:
<bean class="org.springframework.web.servlet.handler.HandlerExceptionResolverComposite">
<property name="exceptionResolvers">
<list>
<bean class="org.springframework.web.servlet.mvc.method.annotation.ExceptionHandlerExceptionResolver">
<constructor-arg ref="exceptionHandlerExceptionResolver" />
</bean>
<bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
<constructor-arg ref="simpleMappingExceptionResolver" />
</bean>
</list>
</property>
<property name="order" value="0"/>
</bean>
