我有这个实现应用程序监听器的应用程序启动类：
package com.test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationListener;
import org.springframework.context.event.ContextRefreshedEvent;
import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import com.test.service.neo.InitializationService;
@Component
@EnableTransactionManagement
public class ApplicationStartup implements ApplicationListener<ContextRefreshedEvent> {
@Autowired
private InitializationService initializationService;
@Override
public void onApplicationEvent(final ContextRefreshedEvent event) {
initializationService.initMasterData();
return;
}
}
这是服务类：
package com.test.service.neo;
public interface InitializationService {
void initMasterData();
void initCategory();
}
这是服务工具类：
package com.test.service.neo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.test.model.neo.Category;
import com.test.repository.neo.CategoryRepository;
@Service
@Transactional
public class InitializationServiceImpl implements InitializationService {
@Autowired
CategoryRepository categoryRepository;
private String[][] categoryList = {
{ "Side Dish" },
{ "Main Dish" },
{ "Dessert" }
};
@Override
public void initMasterData() {
initCategory();
}
@Override
@Transactional
public void initCategory() {
for (String[] categoryName : categoryList) {
Category existCategory = categoryRepository.findByName(categoryName[0]);
if(existCategory == null) {
existCategory = new Category(categoryName[0]);
categoryRepository.save(existCategory);
}
}
}
}
这是我的pom：

当我运行此代码时，我收到此错误：
Error creating bean with name 'scopedTarget.getSession': Scope 'session' is not active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton; nested exception is java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.
如何解决此问题？因为它在春季4.2.6上完美运行
这是我在春季4.2.6的pom：
