1.4pojo以及mapper

//pojo
package net.zzqd.pojo;

public class Customer {
	private Integer id;
	private String name;
	private String gender;
	private String telephone;
	private String address;
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getGender() {
		return gender;
	}
	public void setGender(String gender) {
		this.gender = gender;
	}
	public String getTelephone() {
		return telephone;
	}
	public void setTelephone(String telephone) {
		this.telephone = telephone;
	}
	public String getAddress() {
		return address;
	}
	public void setAddress(String address) {
		this.address = address;
	}
	
}

//mapper
package net.zzqd.mapper;

import java.util.List;

import net.zzqd.pojo.Customer;

public interface CustomerMapper
{
	/**
	 * 查询所有数据
	 */
	public List<Customer> findAll();

	/**
	 * 保存数据
	 * @param customer
	 */
	public void save(Customer customer);
	/**
	 * 根据id查询对象
	 * @param id
	 * @return
	 */
	public Customer findById(Integer id);

	/**
	 * 修改对象数据
	 * @param customer
	 */
	public void update(Customer customer);

	/**
	 * 删除数据
	 * @param id
	 */
	public void delete(Integer[] id);

	
}

//mapper.xml
<?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="net.zzqd.mapper.CustomerMapper">

<!-- 	查询所有数据 用resultType封装-->
	<select id="findAll" resultType="net.zzqd.pojo.Customer">
	select id,
		name,
		gender,
		telephone,
		address
		from
	ssm.t_customer
	
	</select>
<!-- 	添加客户 -->
	<insert id="save" parameterType="net.zzqd.pojo.Customer">
		insert into ssm.t_customer
		(name,gender,telephone,address)
		values
		(
		#{name},
		#{gender},
		#{telephone},
		#{address}
		)
	
	</insert>
<!-- 	根据id查询对象 -->
	<select id="findById" parameterType="int" resultType="net.zzqd.pojo.Customer">
		select id,
		name,
		gender,
		telephone,
		address
		from
	ssm.t_customer
		where id=#{value}
	</select>
<!-- 	根据id修改数据 -->
	<update id="update" parameterType="net.zzqd.pojo.Customer">
		update ssm.t_customer set
		name=#{name},
		gender=#{gender},
		telephone=#{telephone},
		address=#{address}
		where
		id=#{id}
	</update>
<!-- 	根据id删除用户 -->
	<delete id="delete" parameterType="Integer[]">
		delete from ssm.t_customer
		<where>
			id 
			<foreach collection="array" item="id" open="in (" close=")" separator=",">
				#{id}
			</foreach>
		</where>
	</delete>
</mapper>

2.业务层代码

package net.zzqd.service;

import java.util.List;

import net.zzqd.pojo.Customer;

public interface CustomerService {
	//添加用户
	void addCustomer(Customer customer);
	
	//分页查找
	List<Customer> findCustomer(int page,int rows);
}

package net.zzqd.service;

import java.util.List;

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

import com.github.pagehelper.PageHelper;

import net.zzqd.mapper.CustomerMapper;
import net.zzqd.pojo.Customer;

@Service
public class CustomerServiceImpl implements CustomerService {

	@Autowired
	private CustomerMapper customerMapper;
	
	@Override
	public void addCustomer(Customer customer) {
		
		customerMapper.save(customer);
	}

	@Override
	public List<Customer> findCustomer(int page, int rows) {
		List<Customer> customers = customerMapper.findAll();
		PageHelper.startPage(page, rows);
		
		return customers;
	}

}

3.控制层代码

package net.zzqd.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import net.zzqd.pojo.Customer;
import net.zzqd.service.CustomerService;

@Controller
public class CustomerController {
	@Autowired
	private CustomerService customerService;
	
	@RequestMapping("/saveCustomer")
	@ResponseBody
	public String saveCustomer()
	{
		Customer customer = new Customer();
		customer.setName("张张");
		customer.setGender("女");
		customer.setAddress("郑州");
		customer.setTelephone("18888885284");
		
		customerService.addCustomer(customer);
		return "success";
	}
	
	@RequestMapping("/findCustomer/{page}/{rows}")
	@ResponseBody
	public List<Customer> findCustomer(@PathVariable int page, @PathVariable int rows)
	{
		return customerService.findCustomer(page, rows);
	}
}

4.运行

package net.zzqd.app;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

//@EnableAutoConfiguration
//@ComponentScan("net.zzqd.controller")
//默认情况下扫描的是当前包以及当前包的子包
@SpringBootApplication(scanBasePackages= {"net.zzqd"})//组合注解
@MapperScan("net.zzqd.mapper")
public class SpringApplications {
	public static void main(String[] args)
	{
		SpringApplication.run(SpringApplications.class, args);
	}
}

附加：遇到异常：Cannot determine embedded database driver class for database type NONE

暂时未解决

修改后异常：org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘customerController’: Unsatisfied dependency expressed through field ‘customerService’; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘customerServiceImpl’: Unsatisfied dependency expressed through field ‘customerMapper’; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘customerMapper’ defined in file [C:\DevelopTools\JavaFramework\SpringBoot_Parent\SpringBoot-Child10\target\classes\net\zzqd\mapper\CustomerMapper.class]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Property ‘sqlSessionFactory’ or ‘sqlSessionTemplate’ are required
