2.src/main/resources/application.properties

server.port=9090

spring.datasource.url=jdbc:mysql://127.0.0.1:3306/baodan?useUnicode=true&characterEncoding=utf-8

spring.datasource.username=baodan

spring.datasource.password=baodan

spring.datasource.driverClassName=com.mysql.jdbc.Driver

spring.jpa.hibernate.ddl-auto=update

#spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

spring.jpa.database-platform=org.hibernate.dialect.MySQL5Dialect

spring.thymeleaf.cache=false

#显示sql语句

spring.jpa.show-sql=true

3.创建实体类

import java.util.Date;

import javax.persistence.Entity;

import javax.persistence.Id;

@Entity

public class Tenant {

    @Id

    private String id;

    private String name;

    private String phone;

    private String address;

    private String remark;

    private Date gmtCreate;

    private Date gmtModified;

    private Integer status;

    //省略get set

}

4.创建数据访问层

import org.springframework.data.jpa.repository.JpaRepository;

import com.inslife.baodan.domain.Tenant;

public interface TenantDao  extends JpaRepository<Tenant, String> {

}

5.创建service层

import java.util.Date;

import java.util.UUID;

import org.springframework.beans.BeanUtils;

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

import org.springframework.cache.annotation.CachePut;

import org.springframework.cache.annotation.Cacheable;

import org.springframework.stereotype.Service;

import com.inslife.baodan.dao.TenantDao;

import com.inslife.baodan.domain.Tenant;

@Service

public class TenantService {

    @Autowired

    TenantDao tenantDao;

    @Cacheable(cacheNames = { "Tenant" })

    public Tenant getOne(String id) {

        return tenantDao.findOne(id);

    }

    @CachePut(cacheNames = { "Tenant" }, key = "#result.id")

    public Tenant save(Tenant tenant) {

        tenant.setId(UUID.randomUUID().toString().replaceAll("-", ""));

        tenant.setGmtCreate(new Date());

        tenantDao.save(tenant);

        return tenant;

    }

    @CachePut(cacheNames = { "Tenant" }, key = "#result.id")

    public Tenant update(Tenant tenant) {

        Tenant query = tenantDao.findOne(tenant.getId());

        BeanUtils.copyProperties(tenant, query, "id", "gmtCreate");

        query.setGmtModified(new Date());

        tenantDao.save(query);

        return query;

    }

}

6.启动项目

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.cache.annotation.EnableCaching;

import springfox.documentation.swagger2.annotations.EnableSwagger2;

@EnableSwagger2

@EnableCaching

@SpringBootApplication

public class App

{

    public static void main( String[] args )

    {

        System.out.println( "Hello World!" );

        SpringApplication.run(App.class, args);

    }

}
