1、问题描述：
严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.taotao.service.ItemService': Instantiation of bean failed; nested exception is java.lang.ExceptionInInitializerError
2、代码片段：
package com.taotao.service;
import com.taotao.pojo.TbItem;
public interface ItemService {
TbItem getItemById(long id);
}
package com.taotao.service.impl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.taotao.mapper.TbItemMapper;
import com.taotao.pojo.TbItem;
import com.taotao.service.ItemService;
//@Service("itemService")
@Service("ItemService")
public class ItemServiceImpl implements ItemService {
@Autowired
private TbItemMapper itemMapper;
@Override
public TbItem getItemById(long id) {
// TODO Auto-generated method stub
TbItem item = itemMapper.selectByPrimaryKey(id);
return item;
}
}
<!-- 配置包扫描器，扫描所有带@Service注解的类 -->
