實體類

部門

public class Department {
    private String sn;
    private String name;
    private String address;
    //set和get
}

員工

public class Employee {
    private String sn;

    private String password;

    private String name;

    private String departmentSn;

    private String post;
    
    //get和set
}

處理記錄

//處理記錄
public class DealRecord {
    private Integer id;

    private Integer claimVoucherId;

    private String dealSn;

    @DateTimeFormat(pattern = "yyyy-MM-dd hh:mm")
    private Date dealTime;

    private String dealWay;

    private String dealResult;

    private String comment;

    //get和set
}

報銷單

//報銷單
public class ClaimVoucher {
    private Integer id;

    private String cause;

    private String createSn;
    @DateTimeFormat(pattern = "yyyy-MM-dd hh:mm")
    private Date createTime;

    private String nextDealSn;

    private Double totalAmount;

    private String status;

    //get和set
}

報銷單明細

public class ClaimVoucherItem {
    private Integer id;

    private Integer claimVoucherId;

    private String item;

    private Double amount;

    private String comment;

    //set和get
}

dao接口與映射文件

DepartmentDao

package com.imooc.oa.dao;

import com.imooc.oa.entity.Department;
import org.springframework.stereotype.Repository;

import java.util.List;
@Repository("departmentDao")
public interface DepartmentDao {
    void insert(Department department);
    void update(Department department);
    void delete(String sn);
    Department select(String sn);
    List<Department> selectAll();
}

resources/com.imooc.oa.dao/DepartmentDao.xml

<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.4//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.imooc.oa.dao.DepartmentDao">

    <resultMap id="department" type="Department">
        <id property="sn" column="sn" javaType="String"/>
        <result property="name" column="name" javaType="String"/>
        <result property="address" column="address" javaType="String"/>
    </resultMap>


    <insert id="insert" parameterType="Department">
        insert into department values(#{sn},#{name},#{address})
    </insert>

    <update id="update" parameterType="Department">
        update department set name=#{name},address=#{address} where sn=#{sn}
    </update>

    <delete id="delete" parameterType="String">
        delete from department where sn=#{sn}
    </delete>

    <select id="select" parameterType="String" resultMap="department">
        select * from department where sn=#{sn}
    </select>

    <select id="selectAll" resultMap="department">
        select * from department
    </select>

</mapper>

oa_biz中com.imooc.oa.biz/DepartmentBiz.java

package com.imooc.oa.biz;

import com.imooc.oa.entity.Department;

import java.util.List;

public interface DepartmentBiz {
    void add(Department department);
    void edit(Department department);
    void remove(String sn);
    Department get(String sn);
    List<Department> getAll();
}

實現類DepartmentBizImpl

package com.imooc.oa.biz.impl;

import com.imooc.oa.biz.DepartmentBiz;
import com.imooc.oa.dao.DepartmentDao;
import com.imooc.oa.entity.Department;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service("departmentBiz")
public class DepartmentBizImpl implements DepartmentBiz {
    @Autowired
    private DepartmentDao departmentDao;

    public void add(Department department) {
        departmentDao.insert(department);
    }

    public void edit(Department department) {
        departmentDao.update(department);
    }

    public void remove(String sn) {
        departmentDao.delete(sn);
    }

    public Department get(String sn) {
        return departmentDao.select(sn);
    }

    public List<Department> getAll() {
        return departmentDao.selectAll();
    }
}

 發現有錯誤提示Could not autowired,There is more than one bean of XXX

配置文件配置過對mapper層的掃描了，應該是哪裏又按照ByName的方式掃描了一遍，那特麼肯定就是註解啊，自動掃描，按照ByName自動注入

括號內就是指定的要按照ByName注入的mapper層實例

在註解後的括號裏就已經指定了mapper層的bean名稱，然後再看配置文件：

在最後又把mapper掃描了一遍，所以纔會有兩個名字相同的mapper層的bean，解決方法有兩個，要麼去掉註解後面的內容，要麼去掉掃描mapper層的配置。

控制器

oa_web com.imooc.oa.controller.DepartmentController.java

package com.imooc.oa.controller;

import com.imooc.oa.biz.DepartmentBiz;
import com.imooc.oa.entity.Department;
import com.imooc.oa.entity.Employee;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.Map;

@Controller("departmentController")
@RequestMapping("/department")
public class DepartmentController {
    @Autowired
    private DepartmentBiz departmentBiz;
    @RequestMapping("/list")
    public String list(Map<String,Object> map){
        map.put("list",departmentBiz.getAll());
        return "department_list";
    }
    @RequestMapping("/to_add")
    public String toAdd(Map<String,Object> map){
        map.put("department",new Department());
        return "department_add";
    }
    @RequestMapping("/add")
    public String add(Department department){
        departmentBiz.add(department);
        return "redirect:list";
    }

    @RequestMapping(value = "/to_update",params = "sn")
    public String toUpdate(String sn,Map<String,Object> map){
        map.put("department",departmentBiz.get(sn));
        return "department_update";
    }
    @RequestMapping("/update")
    public String update(Department department){
        departmentBiz.edit(department);
        return "redirect:list";
    }
    @RequestMapping(value = "/remove",params = "sn")
    public String remove(String sn){
        departmentBiz.remove(sn);
        return "redirect:list";
    }

}

運行出錯

錯誤:org.apache.ibatis.binding.BindingException: Invalid bound statement (not found)解決方法

 

在target中，DepartmentDao.class和xml沒有在同一個包下，xml並沒有編譯進來，所以我考慮下到可能xml所在的包有問題。

原先我的包創建命名，com.imooc.oa.dao，如圖

但是resources中建包是directory，directory和package建包在名稱上存在區別。

package建包，"."作爲作爲創建多級目錄。

directory建包，"."作爲名稱的一部分，要建多級目錄需要"/"

所以我命名，com.imooc.oa.dao對於directory而言是一個包，這個包名稱中有"."。

最後我通過 com/imooc/oa/dao，程序沒有報錯。
