环境：

1. 开发IDE：idea
2. spring boot:2.1.1 release
3. tk.mybatis 4
4. mysql 5
5. druid 1.0.25

• 使用spring boot 初始化项目

    pom.xml

    4.0.0
    
        org.springframework.boot

                        mysql

                        5.1.29
                    
                    
                        tk.mybatis
                        mapper
                        4.0.0
                    
                
            
        
    

• 配置mappers
   

  spring:
    datasource:
      type: com.alibaba.druid.pool.DruidDataSource
      url: jdbc:mysql://localhost:3306/test
      username: root
      password:
      driver-class-name: com.mysql.jdbc.Driver
  mapper:
    mappers:
      - tk.mybatis.mapper.common.Mapper
      - tk.mybatis.mapper.common.Mapper2
    not-empty: true
  # 自定义xml文件时引入，否则可以不引入
  mybatis:
    mapperLocations: classpath:mapper/*.xml

  
   
• 配置扫描包路径

package com.zjchsoft.bi.tkmb;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@tk.mybatis.spring.annotation.MapperScan(basePackages = "com.zjchsoft.bi.tkmb.mapper")
public class TkmbApplication {

    public static void main(String[] args) {
        SpringApplication.run(TkmbApplication.class, args);
    }

}

•  添加自定义查询
   

  
  
  
    
      
      
      
      
      
    
    
          id, user_name, password, sex
      
    
      select
      
      from t_user
      where id = #{id}
    
  

   

package com.zjchsoft.bi.tkmb.mapper;

import com.zjchsoft.bi.tkmb.entity.User;
import tk.mybatis.mapper.common.Mapper;
//不用添加注解，starter会自动扫描继承Mapper的类文件
public interface UserMapper extends Mapper {
    //自定义查询
    public User selectById2(int id);
}

 

使用控制层进行访问
 

package com.zjchsoft.bi.tkmb.controller;

import com.zjchsoft.bi.tkmb.entity.User;
import com.zjchsoft.bi.tkmb.mapper.UserMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController
@RequestMapping("/user")
public class Usercontroller {

    @Autowired
    UserMapper userMapper;

    @GetMapping("/all")
    public List getUser(){
        return userMapper.selectAll();
    }

    @GetMapping("/get/{id}")
    public User getUser(@PathVariable("id") int id){
        return userMapper.selectById2(id);
    }
}

• 启动项目进行访问
