springboot(七)：整合mybatis-plus

1. 引入依賴

		<dependency>
			<groupId>com.baomidou</groupId>
			<artifactId>mybatis-plus</artifactId>
			<version>2.1.1</version>
		</dependency>
		<dependency>
			<groupId>com.baomidou</groupId>
			<artifactId>mybatisplus-spring-boot-starter</artifactId>
			<version>1.0.5</version>
		</dependency>

2. 修改配置文件

將mapper的掃描路徑配置由mybatis改爲mybatis-plus：

mybatis:
  type-aliases-package: com.szl.entity
  mapper-locations: classpath:mapper/*.xml

改爲：

mybatis-plus:
  type-aliases-package: com.szl.entity
  mapper-locations: classpath:mapper/*.xml

3. 修改entity

@TableName("customer")
public class Customer implements Serializable{

	/**
	 * 
	 */
	@TableField(exist = false)
	private static final long serialVersionUID = 6983500689524183915L;
	@TableId
	private String uuid;//主鍵
	private String delFlag;//邏輯刪除標識
	private String opeTime;//操作時間
	private String oper;//操作人
	private String createTime;//創建時間
	private String customerName;//用戶名
	private String email;//郵箱
	private String frozenState;//凍結狀態
	private String frozenType;//凍結類型
	private String lastWrongLoginTime;//最後登錄錯誤時間
	private Integer loginErrorTimes;//登錄錯誤次數
	private String mobile;//手機號
	private String password;//登錄密碼
	private String salt;//密碼哈希

    //getter and setter

在entity上增加註解@TableName("customer")，實體類對應的表名

主鍵上加註解：@TableId

非表字段，需要加上註解：@TableField(exist = false)

4. 修改Mapper，Service，ServiceImpl，Controller

Mapper：繼承BaseMapper<T>

import com.baomidou.mybatisplus.mapper.BaseMapper;
import com.szl.entity.Customer;


public interface CustomerMapper extends BaseMapper<Customer>{

}

Service：繼承IService<T>

package com.szl.service;

import com.baomidou.mybatisplus.service.IService;
import com.szl.entity.Customer;

public interface CustomerService extends IService<Customer>{


}

ServiceImpl：繼承ServiceImpl<BaseMapper<T>, T>

package com.szl.service.impl;

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

import com.baomidou.mybatisplus.service.impl.ServiceImpl;
import com.szl.entity.Customer;
import com.szl.mapper.CustomerMapper;
import com.szl.service.CustomerService;

@Service
public class CustomerServiceImpl extends ServiceImpl<CustomerMapper, Customer>implements CustomerService{

}

修改Controller中的查詢方法，不需要在mapper.xml中寫sql，mapper，service都不用寫方法，調用mybatis-plus封裝好的方法即可。

	/**
	 * 根據手機號查詢用戶信息
	 * @param mobile
	 * @return
	 */
	@RequestMapping(value = "/getCustomer", method = RequestMethod.GET)
	public ResultVo getCustomer(@RequestParam(value = "mobile") String mobile){
		
//		Customer customer = customerService.getCustomerByMobile(mobile);
		EntityWrapper<Customer> entity = new EntityWrapper<Customer>();
		entity.where("mobile", mobile);
		List<Customer> list = customerService.selectList(entity);
		return ResultVo.getData(ResultEnum.SUCCESS, list);
	}

查看結果，和調用customerService.getCustomerByMobile(mobile)一致。
