找不到实现类com.jiebai.crud.service.InfoService

有这个类
package com.jiebai.crud.service;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.jiebai.crud.bean.Info;
import com.jiebai.crud.dao.InfoMapper;

@Service
public class InfoService {

@Autowired
InfoMapper infomapper;

public List<Info> getAll(){
    return infomapper.selectByExample(null);

}

}

图片说明

log中关键信息点有:
1、Error creating bean with name 'infoController
2、: Unsatisfied dependency expressed through field 'infoService'
3、No qualifying bean of type 'com.jiebai.crud.service.InfoService' available

根据以上可以判断出,你应该是没有标示出InfoService,你或许少个注解@Service
