Question

我正在尝试为我的点火缓存实现持久存储，我正在使用CacheJdbcPojoStoreFactory，我的缓存存储工厂初始化看起来像这样

@Autowired
DataSorce datasource; 
@Bean  
public CacheJdbcPojoStoreFactory<?, ?> cacheJdbcdPojoStorefactory(){
CacheJdbcPojoStoreFactory<?, ?> factory = new CacheJdbcPojoStoreFactory<>();
factory.setDataSource(dataSource);
return factory;
 }

我的缓存实现看起来像这样

CacheConfiguration pesonConfig = new CacheConfiguration();
pesonConfig.setName("personCache");
cacheJdbcdPojoStorefactory.setTypes(jdbcTypes.toArray(new JdbcType[jdbcTypes.size()]));
Collection<QueryEntity> qryEntities = new ArrayList<>();
qryEntities.add(qryEntity);
pesonConfig.setQueryEntities(qryEntities);
pesonConfig.setCacheStoreFactory((Factory<? extends CacheStore<Integer, Person>>) cacheJdbcdPojoStorefactory);
ROCCache<Integer, Person> personCache= rocCachemanager.createCache(pesonConfig);
personCache.put(1, p1);
personCache.put(2, p2)

（我正在传递正确的查询实体和JdbcTypes，为简单起见，我没有在这里显示代码）但是，当我运行此代码时，我得到下面的堆栈跟踪

当我调试时，我可以看到我的数据源参数在cacheJdbcdPojoStorefactory对象中正确设置。我哪里错了？

Answer 1

您可以提供其bean ID，而不是连接数据源bean并将其设置为工厂，工厂将从应用程序上下文中获取它。这是一个例子：

@Bean  
public CacheJdbcPojoStoreFactory<?, ?> cacheJdbcdPojoStorefactory(){
    CacheJdbcPojoStoreFactory<?, ?> factory = new CacheJdbcPojoStoreFactory<>();
    factory.setDataSourceBean("data-source-bean");
    return factory;
}

问题是工厂将被序列化，但数据源字段是暂时的。这使setDataSource()属性非常混乱，我认为它应该被弃用并重新编写。
