新手在学ssm，整合的时候发现好像死活都注入不了
但是我注释也扫了，也加了@注释
jdk1.8

下面的tomcat（9.0.16）的运行日志

```下面是代码

package all.service.impl;

import all.dao.AccountDao;
import all.domain.Account;
import all.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;


import java.util.List;

@Service("accountService")
public class AccountServiceImpl implements AccountService {


    @Autowired
    private AccountDao accountDao;

    public void setAccountDao(AccountDao accountDao) {
        this.accountDao = accountDao;
    }

    @Override
    public List<Account> findAll() {

        return accountDao.findAll();
    }

    @Override
    public void save() {
        Account account = new Account();
        accountDao.save(account);
    }
}

```package all.controller;

import all.domain.Account;
import all.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;


import java.util.List;

@Controller
@RequestMapping("/account")
public class AccountController {

    @Autowired
    private AccountService accountService;

    public void setAccountService(AccountService accountService) {
        this.accountService = accountService;
    }

    @RequestMapping("/findAll")
    public String findAll(Model model){
        List<Account> accounts = accountService.findAll();
        model.addAttribute("accounts",accounts);
        return "success";
    }
    @RequestMapping("/save")
    public void save(Account account){
       accountService.save();
    }
}

package all.dao;

import all.domain.Account;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface AccountDao {

    @Select("select * from account")
    public List<Account> findAll();

    @Insert("insert into account (name,money) values(#{name},#{money})")
    public void save(Account account);
}

经过我的测试，accountService不注入accountDao就不会出错，而accountDao单独配合Mybatis运行也没有问题，所以应该是spring整合mybatis那里出错了，但是我不知道具体是哪里出错了，希望各位大佬能帮我看一下。。

现在把applicationContext.xml文件贴出来给你们看看

<!--    spring整合mybatis框架-->
<!--    配置连接池-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="com.mysql.jdbc.Driver"/>
        <property name="jdbcUrl" value="jdbc:mysql:///ssm?serverTimezone=UTC"/>
        <property name="user" value="root"/>
        <property name="password" value="0759"/>

    </bean>


<!--配置工厂 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
    </bean>


<!--   配置接口所在的包 -->
    <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="all.dao"></property>
    </bean>

配置文件中定义了

<context:component-scan base-package="">

吗？

为什么要多写这个方法呢setAccountService
