Springboot+mybatisplus+SSM模板(未完待续)

mapper.xml：

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

<mapper namespace="com.wanli.dao.UserDao">
    <!-- 根据某字段查询所有 -->
    <select id="getUserByType" resultType="com.wanli.entity.UserEntity" parameterType="java.lang.String">
       select * from user

<!-- 可根据自己的需求，是否要使用 ，property是实体类属性值，column是数据库字段值，用resultMap可以简化配置，假如数据库中字段名修改了，如果我们用的resultType的话，可能就要去改实体类了，而reusltMap我们只需要修改对应column属性-->
<resultMap id="userMap" type="com.wanli.city.entity.CityPopulationEntity" >

dao接口：

import java.util.List;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.wanli.entity.UserEntity;
@Mapper
public interface UserDao extends BaseMapper<UserDao>{
    // mapper文件中如果有if判断时需要加注解@Param，否则报错,@param中的type是sql文件中的占位符变量，要保持一致
     List<UserlEntity> getUserByType(@Param("type") String type);
}

service接口：

import java.util.List;
import com.wanli.entity.CityHospitalEntity;

public interface CityHospitalService {
    List<CityHospitalEntity> getHospitalByType(String type);
}

service实现类:

import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.wanli.dao.CityHospitalDao;
import com.wanli.entity.CityHospitalEntity;
import com.wanli.service.CityHospitalService;
@Service
public class CityHospitalServiceImpl implements CityHospitalService {

    @Autowired
    private CityHospitalDao hospitalDao;
    
    @Override
    public List<CityHospitalEntity> getHospitalByType(String type) {
        // TODO Auto-generated method stub
        return hospitalDao.getHospitalByType(type);
    }

}

controller层:

import java.util.List;
import javax.servlet.http.HttpServletRequest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.supermap.ggzy.city.entity.CityHospitalEntity;
import com.supermap.ggzy.city.service.CityHospitalService;

@RestController
@RequestMapping("cityHospital")
public class CityHospitalController {

    @Autowired
    private CityHospitalService hospitalService;
    
    @RequestMapping("/getHospitalByType")
    public List<CityHospitalEntity> getHospitalByType(HttpServletRequest request){
        
        String type = request.getParameter("type");
        
        List<CityHospitalEntity> list = hospitalService.getHospitalByType(type);
        
        return list;
        
    }
}
