Springboot中Hibernate根据表名获取model类

@Bean
    public Map metaMap(EntityManagerFactory factory) throws ClassNotFoundException {
        if (factory.unwrap(SessionFactory.class) == null) {
            throw new NullPointerException("factory is not a hibernate factory");
        }
        SessionFactory sessionFactory = factory.unwrap(SessionFactory.class);
         Map<String, ClassMetadata> metaMap = sessionFactory.getAllClassMetadata();
        Map<String, Class> map = new HashMap<>();
        for (String key : metaMap.keySet()) {
            AbstractEntityPersister classMetadata = (AbstractEntityPersister) metaMap
                    .get(key);
            String tableName = classMetadata.getTableName().toLowerCase();
            int index = tableName.indexOf(".");
            if (index >= 0) {
                tableName = tableName.substring(index + 1);
            }
            map.put(tableName, Class.forName(key));
        }
        return map;
    }
