应用启动tomcat时报错：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'commonProcessBean': Autowiring of fields failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.taobao.relationrecommend.biz.ao.RecommendCollection com.taobao.relationrecommend.biz.util.share.CommonProcessBean.recommendCollection; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'recommendCollection' defined in class path resource [biz/csk-relationrecommend.xml]: Cannot resolve reference to bean 'i2i023' while setting bean property 'initDaoBean' with key [0]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'i2i023': Autowiring of fields failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.taobao.relationrecommend.biz.bo.csk.CollectItemRecommendManager com.taobao.relationrecommend.biz.dao.Item2Item023.collectItemRecommendManager; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'collectitem': Autowiring of fields failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: protected com.taobao.relationrecommend.biz.util.ItemLoader com.taobao.relationrecommend.biz.bo.csk.CollectItemRecommendManager.itemLoader; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'itemLoader': Autowiring of fields failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.taobao.forest.service.StdCategoryServices com.taobao.relationrecommend.biz.util.ItemLoader.stdCategoryServices; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'forestServices' defined in class path resource [biz/forest-relationrecommend-client.xml]: Invocation of init method failed; nested exception is java.lang.StackOverflowError
