问题描述

我有一个 GWT+Hibernate+JPA+Spring 配置文件，它适用于 Spring 3.0.x + Hibernate 3.6.x.当我升级到 Spring 3.1 和 Hibernate 4.0 时，抛出以下异常:

是否存在与 Hibernate 4 和 Spring 3.1 的已知不兼容?

解决方案

此问题已修复 在 Hibernate 中4.1.4.

<小时>

我遇到了同样的问题，它似乎与 Jetty 类加载器(GWT 插件使用 Jetty 用于托管模式)、GWT 插件和 Hibernate(尽管它显然也与其他库一起出现)有关.

>

它类似于此处提到的错误 Hibernate 错误报告，但在我们的案例中，我们'通过 GWT 插件重新运行它，它会导致 ConnectionProvider 的 ClassCastException.

错误报告中提到的修复程序应该可以解决该特定问题.

对于 org.hibernate.service.classloading.internalClassLoaderServiceImpl，通过构造函数将父级设置为空:

this.classClassLoader = new ClassLoader(null) {@覆盖受保护的类findClass(String name) 抛出 ClassNotFoundException {对于(类加载器加载器:classLoadingClassLoaders){尝试 {返回 loader.loadClass( 名称 );}捕获(异常忽略){}}throw new ClassNotFoundException("无法加载请求的类:" + name );}};

I have a GWT+Hibernate+JPA+Spring configuration file which is OK with Spring 3.0.x + Hibernate 3.6.x. When I upgraded to Spring 3.1 and Hibernate 4.0, the following exception is thrown:

Is there any known incompatibility withe Hibernate 4 and Spring 3.1?

解决方案

This issue is fixed in Hibernate 4.1.4.

I had the same problem, and it seems to be related to the Jetty classloader (the GWT plugin uses Jetty for hosted mode), the GWT plugin and Hibernate (although it apparently crops up with other libraries as well).

It's similar to the bug mentioned here Hibernate Bug Report but in our cases we're running it via the GWT plugin and it causes a ClassCastException for the ConnectionProvider.

The fix mentioned in the bug report should fix that particular problem.

For org.hibernate.service.classloading.internalClassLoaderServiceImpl set the parent to null via the constructor:

this.classClassLoader = new ClassLoader(null) {
        @Override
        protected Class<?> findClass(String name) throws ClassNotFoundException {
            for ( ClassLoader loader : classLoadingClassLoaders ) {
                try {
                    return loader.loadClass( name );
                }
                catch (Exception ignore) {
                }
            }
            throw new ClassNotFoundException( "Could not load requested class : " + name );
        }
};

这篇关于GWT 开发模式 + Spring 3.1 + Hibernate 4.0.1 中的异常的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
