Dao接口不能正确初始化,下面是相关类和配置文件。

javaBean

package com.mars.dal.bean;

import java.math.BigDecimal;

public class Recharge {
    private long rechargeID;
    private BigDecimal amount;
    private long time;
    private String dateTime;
    private int quarter;
    public long getRechargeID() {
        return rechargeID;
    }
    public void setRechargeID(long rechargeID) {
        this.rechargeID = rechargeID;
    }
    public BigDecimal getAmount() {
        return amount;
    }
    public void setAmount(BigDecimal amount) {
        this.amount = amount;
    }
    public long getTime() {
        return time;
    }
    public void setTime(long time) {
        this.time = time;
    }
    public String getDateTime() {
        return dateTime;
    }
    public void setDateTime(String dateTime) {
        this.dateTime = dateTime;
    }
    public int getQuarter() {
        return quarter;
    }
    public void setQuarter(int quarter) {
        this.quarter = quarter;
    }
    
}

Mybatis Mapper 

package com.mars.dal.mapper;

import java.util.List;

import com.mars.dal.bean.Recharge;

public interface RechargeMapper {
    
    public int addCount(Recharge count);
    
    public List<Recharge> getCountPerMonthByYear(String year);

    public List<Recharge> getCountPerQuarterByYear(String year);

    public List<Recharge> getCountYearByYear(String year);
    
}

Mybatis配置文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">

    </mappers>
    
</configuration>

 

 

RehcargeMapper.xml

<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

    </select>
 
</mapper>

RechargeServiceImpl.java

package com.mars.dal.service.impl;

import java.util.List;


import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;

import com.mars.dal.bean.Recharge;
import com.mars.dal.mapper.RechargeMapper;
import com.mars.dal.service.RechargeService;

public class RechargeServiceImpl implements RechargeService {
    
    private RechargeMapper rechargeMapper;

    public RechargeMapper getRechargeMapper() {
        return rechargeMapper;
    }
    public void setRechargeMapper(RechargeMapper rechargeMapper) {
        this.rechargeMapper = rechargeMapper;
    }

    public void getRechargeDatas(String year) {
        System.out.println("ddddddddddddd");
        System.out.println(this.rechargeMapper);
    
    }
    
    
}

Spring配置文件  applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>


    
     <context:component-scan base-package="com.mars.dal" />
     <context:annotation-config />

  
  <!-- 数据源 -->
  <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
    <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
    <property name="url" value="jdbc:mysql://127.0.0.1/count"></property>
    <property name="username" value="root"></property>
    <property name="password" value="123456"></property>
  </bean>


 <!-- 声明式事务 -->
  <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource" />
  </bean>
  
  <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
 <property name="configLocation" value="classpath:com/mars/dal/mapper/Configuration.xml" />
    <property name="dataSource" ref="dataSource" />
  </bean>
 
  
  <bean id="rechargeMapper" class="org.mybatis.spring.mapper.MapperFactoryBean">
    <property name="mapperInterface" value="com.mars.dal.mapper.RechargeMapper" />
    <property name="sqlSessionFactory" ref="sqlSessionFactory" />
  </bean>
  <bean id="rechargeService" class="com.mars.dal.service.impl.RechargeServiceImpl">
    <property name="rechargeMapper" ref="rechargeMapper"></property>
  </bean>
  
</beans>

启动服务后service中的this.rechangeMapper始终为null.刚上手学Spring,请问哪边出错了!

问题补充:
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"

这部分是Spring配置文件头,提问的时候判断成广告不给发
