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() {return state;}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.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

</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;

@Service
public class UserServiceImpl implements UserServiceInterface {@Autowiredprivate UserMapperInterface userMapperInterface;@Overridepublic List<Users> SelectAll() {return userMapperInterface.SelectAll();}@Overridepublic List<Users> SelectVague(String name, String type, String Depa) {return userMapperInterface.SelectVague(name,type,Depa);}@Overridepublic 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
