我有一个基于Spring Web模型 – 视图 – 控制器(MVC)框架的项目. Spring Web模型 – 视图 – 控制器(MVC)框架的版本是3.2.8.
我用这个方法实现了一个过滤器：
@H_404_7@public void doFilter(ServletRequest request,ServletResponse response,FilterChain filterChain) throws ServletException,IOException {
HttpServletRequest httpServletRequest;
ThreadContext threadContext;
//String path = ((HttpServletRequest) request).getRequestURI();
if (request instanceof HttpServletRequest) {
httpServletRequest = (HttpServletRequest) request;
threadContext = ThreadContext.getInstance();
try {
DetailedUser ecasUser = (DetailedUser) httpServletRequest.getUserPrincipal();
if (ecasUser != null) {
threadContext.setDomainUsername(ecasUser.getDomainUsername());
}
} catch (Exception e) {
e.printStackTrace();
}
if (httpServletRequest.getRemoteUser()!=null) {
threadContext.setUserID(httpServletRequest.getRemoteUser());
}
}
try {
if (filterChain != null) {
filterChain.doFilter(request,response);
}
} catch (IOException e) {
LOGGER.equals(e.getMessage());
}
}
在这行filterChain.doFilter(request,response);我有这个奇怪的错误：
@H_404_7@] Root cause of ServletException.

这是导入的库：
@H_404_7@
它似乎与pom.xml文件的hibernate依赖关系有关
最佳答案
这个错误背后的原因是,Hibernate在构建PersistenceProviderResolver中返回类路径上所有PersistenceProviders的列表.由于Weblogic lib包含JPA 1.0,因此它返回JPA2.0以及JPA 1.0持久性提供程序.
创建一个HibernatePersistenceProviderResolver类作为
@H_404_7@ public class HibernatePersistenceProviderResolver implements PersistenceProviderResolver {
private volatile PersistenceProvider persistenceProvider = new HibernatePersistence();
public List getPersistenceProviders() {
return Collections.singletonList(persistenceProvider);
}
public void clearCachedProviders() {
persistenceProvider = new HibernatePersistence();
}
public static void register() {
PersistenceProviderResolverHolder
.setPersistenceProviderResolver(new HibernatePersistenceProviderResolver());
}
}
@H_404_7@public class HibernateContextListener implements ServletContextListener{
@Override
public void contextInitialized(ServletContextEvent sce) {
HibernatePersistenceProviderResolver.register();
}
@Override
public void contextDestroyed(ServletContextEvent sce) {
// TODO Auto-generated method stub
}
}
在web.xml中添加侦听器条目
