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);
    }
}

thymeleaf模板

<!DOCTYPE html>
