创建实体类

package com.item.model;

public class Users {
    private int id;
    private String name;
    private String sex;
    private int age;
    private String phone;
    private String department;
    private String type;
    private Double price;
    private String state;
    private String register_time;

    public Users(int id, String name, String sex, int age, String phone, String department, String type, Double price, String state, String register_time) {
        this.id = id;
        this.name = name;
        this.sex = sex;
        this.age = age;
        this.phone = phone;
        this.department = department;
        this.type = type;
        this.price = price;
        this.state = state;
        this.register_time = register_time;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public String getDepartment() {
        return department;
    }

    public void setDepartment(String department) {
        this.department = department;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    public Double getPrice() {
        return price;
    }

    public void setPrice(Double price) {
        this.price = price;
    }

    public String getState() {

    }

    public void setState(String state) {
        this.state = state;
    }

    public String getRegister_time() {
        return register_time;
    }

    public void setRegister_time(String register_time) {
        this.register_time = register_time;
    }

    public Users() {
    }
}

创建mapper接口

package com.item.dao;

import com.item.model.Users;
import org.apache.ibatis.annotations.Param;

import java.util.List;

public interface UserMapperInterface {
//    查询全部
    List<Users>SelectAll();
//    模糊查询
    List<Users>SelectVague(@Param("name") String name,
                           @Param("Type") String type,
                           @Param("Depa") String Depa);
    //    新增
    int Inserts  (@Param("username") String name,
                 @Param("Sex") String Sex,
                 @Param("ages") String ages,
                 @Param("phone") String phone,
                 @Param("deap") String deap, @Param("Types") String Types, @Param("Proice") String Proice);
}

创建Service接口

package com.item.service;

import com.item.model.Users;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Service;

import java.util.List;

public interface UserServiceInterface {
    //    查询全部
    List<Users> SelectAll();
    //    模糊查询
    List<Users>SelectVague(@Param("name") String name,
                           @Param("Type") String type,
                           @Param("Depa") String Depa);
//    新增
    int Inserts  (@Param("username") String name,
                 @Param("Sex") String Sex,
                 @Param("ages") String ages,
                 @Param("phone") String phone,
                 @Param("deap") String deap, @Param("Types") String Types, @Param("Proice") String Proice);

}

设置mapper

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.item.dao.UserMapperInterface">
<!--    查询全部-->
<select id="SelectAll" resultType="Users">
    select * from tb_patient
</select>
<!--    模糊查询-->
    <select id="SelectVague" resultType="Users">
        select * from tb_patient where name like "%${name}%" and type LIKE "%${Type}%" and department Like "%${Depa}%"
    </select>
<!--    新增数据-->
    <insert id="Inserts">
        INSERT INTO `hospital_db`.`tb_patient` (`id`, `name`, `sex`, `age`, `phone`, `department`, `type`, `price`, `state`, `register_time`) VALUES
        (null , '${username}', '${Sex}', '${ages}', '${phone}', '${deap}', '${Types}', '${Proice}', '未就诊', NOW());
    </insert>
</mapper>

实现service

package com.item.serviceimpl;

import com.alibaba.druid.filter.AutoLoad;
import com.item.dao.UserMapperInterface;
import com.item.model.Users;
import com.item.service.UserServiceInterface;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;
@Service
public class UserServiceImpl implements UserServiceInterface {
    @Autowired
    private UserMapperInterface userMapperInterface;
    @Override
    public List<Users> SelectAll() {
        return userMapperInterface.SelectAll();
    }

    @Override
    public List<Users> SelectVague(String name, String type, String Depa) {
        return userMapperInterface.SelectVague(name,type,Depa);
    }

    @Override
    public int Inserts(String name, String Sex, String ages, String phone, String deap, String Types, String Proice) {
        return userMapperInterface.Inserts(name,Sex,ages,phone,deap,Types,Proice);

    }




}

配置控制层

```css
