我在开发中使用SpringTest测试机制进行服务层的单元测试，结果单元测试在执行初始化方法时就抛出异常，错误如下
[code="java"]java.lang.IllegalStateException: Failed to load ApplicationContext

单元测试类继承了Spring的AbstractTransactionalJUnit4SpringContextTests类，然后测试中使用的Spring配置如下：

DictionaryManagerImpl代码大体如下：
[code="java"]@Service("dictionaryManager")
public class DictionaryManagerImpl extends BaseManager implements
DictionaryManager {
/**
* 存放字典使用实体集合的Map，其中key对应那个字典目录，value为这个字典目录有那些实体对象的那个字段使用着
*/
private Map> dictionaryAccessMap = new HashMap>();
@PostConstruct
public void init() {
//读取字典使用实体数据至dictionaryAccessMap，以供在执行删除字典数据时判断数据是否被使用的依据
List<DictAccess> list = dao.query(DictAccess.class, null);
for (DictAccess dictAccess : list) {
String catalogCode = dictAccess.getCatalogCode();
List<DictAccess> dictAccessList = dictionaryAccessMap.get(catalogCode);
if (dictAccessList == null) {
dictAccessList = new ArrayList<DictAccess>();
dictionaryAccessMap.put(catalogCode, dictAccessList);
}
dictAccessList.add(dictAccess);
}
}
... ...
