spring boot jpa 异常 - Githubissues

energicchainblock commented 7 years ago

当集成spring boot jpa,加载spring-orm。jar,由于org.springframework.beans.factory.support.PersistenceAnnotationBeanPostProcessor #requiresDestruction 会检查 rpc 对象的hashcode 方法，从而调研com.weibo.api.motan.proxy.RefererInvocationHandler#invoke 调研错误，抛出异常， can not invoke local method:hashCode

后续会对动态代理类的hashcode和equals等方法进行简单实现。不过正常情况下应该不会出现对motan refer动态代理类的判等操作呀？是注入时没有指定代理类的name吗

有办法解决吗？1.1.0版本仍然报没有hashCode错误

没办法，只好手动跳过，创建自定义的PersistenceAnnotationBeanPostProcessor，覆盖requiresDestruction，判断bean为接口时，直接跳过

import java.lang.reflect.Proxy;

import org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor;

public class CustomPersistenceAnnotationBeanPostProcessor extends PersistenceAnnotationBeanPostProcessor {

    private static final long serialVersionUID = 6356435448579269667L;

    @Override
    public boolean requiresDestruction(Object bean) {
        Class<? extends Object> clazz = bean.getClass();
        //根据接口类特征修改条件
        if (Proxy.isProxyClass(clazz) && 1 == clazz.getInterfaces().length) {
            return false;
        }
        return super.requiresDestruction(bean);
    }

}

注入bean

@Bean(AnnotationConfigUtils.PERSISTENCE_ANNOTATION_PROCESSOR_BEAN_NAME)
@Primary
public PersistenceAnnotationBeanPostProcessor persistenceAnnotationBeanPostProcessor() {
    return new CustomPersistenceAnnotationBeanPostProcessor();
}

这个问题只在尝试使用@Autowired等注解注入的时候才会出现，如果使用@MotanReferer注入是不会出现这个问题的
