阅读更多关于 Spring3 's @Transactional @Scheduled not committed to DB?

This is my 1st time trying Spring3's @Scheduled , but found I cannot commit to DB. This is my code : @Service public class ServiceImpl implements Service , Serializable { @Inject private Dao dao; @Override @Scheduled(cron="0 0 * * * ?") @Transactional(rollbackFor=Exception.class) public void hourly() { // get xxx from dao , modify it dao.update(xxx); } } I think it should work , I can see it starts-up hourly and load xxx from DB , but data is not committed to DB. There's been tx:annotation-driven in spring's xml : <bean id="entityManagerFactoryApp" class="org.springframework.orm.jpa

阅读更多关于 Change @ManagedResource objectName dynamically

I am creating prototype beans programatically/dynamically. I want those beans after initiation to be in the jmx console. How I can distinguish between them? I am using anotations in order to add my beans to the jmx and I have @ManagedResource(objectName="bean:name=MybBean") I need to inject the objectName dynamically. Any idea how could I do it? Here's my jmx configuration: <context:mbean-export server="mbeanServer" /> <bean id="mbeanServer" class="org.springframework.jmx.support.MBeanServerFactoryBean" /> <bean id="exporter" class="org.springframework.jmx.export.MBeanExporter" lazy-init=

I am migration from Spring 3.0.5 to 3.1 since I need to have custom RequestMappingHandlerMapping.

Is there a way to use conjunction of servlet-context.xml and at the same

Integrating JSR-356 WebSocket @ServerEndpoint with Spring 3 beans

阅读更多关于 Integrating JSR-356 WebSocket @ServerEndpoint with Spring 3 beans

问题 I'm using Spring 3.2.5 without full new JSR-356 WebSockets support. I would like to have singleton-bean reference in my @ServerEndpoint WebSocket server, which is instantiated by servlet container itself, not in Spring context. What is the clean way to do it? My current solution: I made @Service singleton bean with instance in static field: @Service public class WebSocketSupportBean { private volatile static WebSocketSupportBean instance = null; public static WebSocketSupportBean getInstance(

阅读更多关于 Autowiring a service into a validator

问题 This example is a bit contrived; I've simplified it to remove extraneous details and to focus on the problem I am having. I have a validator that looks like this: @Component public class UniqueUsernameValidator implements ConstraintValidator<UniqueUsername, String> { @Autowired UsernameService usernameService; @Override public void initialize(UniqueUsername uniqueUsername) { } @Override public boolean isValid(String s, ConstraintValidatorContext constraintValidatorContext) { return

I have tried all sorts of RnD but am still stuck! :( Apparently my problem lies in my servlet.xml file (the schema isnt getting validated!)

How to programmatically log user in with Spring Security 3.1

阅读更多关于 How to programmatically log user in with Spring Security 3.1

问题 What's the proper way to programmatically log a web visitor in under a particular username in Spring and Spring Security 3.1? It seems the way I was doing it under 2.5 has changed a little. I'm sure there's a much better way of doing this now. Basically, when I create a new user, I need to also log them in at the same time. 回答1: Create an Authentication (usually a UsernamePasswordAuthenticationToken ) and then call SecurityContextHolder.getContext().setAuthentication(authentication) 回答2: This

EJB 3.1 or Spring 3.. When to choose which one?

阅读更多关于 EJB 3.1 or Spring 3.. When to choose which one?

EJB achieved many improvements in 3.x versions, Spring is also commonly used and version 3 is a good alternative. There are many articles on web, but no exact comparison about ejb3x versus spring3x.. Do you have any ideas about them, in real world examples which one is better at which conditions? For example, we want to separate db and server, which means our application will be on a server, our database will be in another server.. EJB remoting vs Cluster4Spring etc ? Doing everyting @Annotation is always good? configuration never needed? For your use case where the application runs on one
