一、下载jar包pom.xml配置
    	
     
      4.0.0
     	
     
      com.hxkj
     	
     
      spring-data-jpa
     	
     
      0.0.1-SNAPSHOT
     	
     	
     		
      
       org.springframework.boot
      		
      
       spring-boot-starter-parent
      		
      
       1.4.0.RELEASE
      	
     	
     	
     		
      			
       
        org.springframework.boot
       			
       
        spring-boot-starter-web
       		
      		
      		
      			
       
        mysql
       			
       
        mysql-connector-java
       		
      		
      		
      			
       
        org.springframework.boot
       			
       
        spring-boot-starter-data-jpa
       		
      		
      			
       
        org.springframework.boot
       			
       
        spring-boot-configuration-processor
       			
       
        true
       		
      	
     	
     	
     		
      			
       				
        
         org.springframework.boot
        				
        
         spring-boot-maven-plugin
        			
       		
      	
     
    上面的jar包，包含了spring boot的基本包，还有连接mysql的驱动包，和data jpa包。我用的spring boot最新版本进行搭建的。二、application.properties配置#jdbc datasource#数据源的基本配置spring.datasource.url=jdbc:mysql://127.0.0.1:3306/datajpa?useUnicode=true&characterEncoding=utf8spring.datasource.username=rootspring.datasource.password=rootspring.datasource.driver-class-name=com.mysql.jdbc.Driver#tomcat的连接配置，随个人的机器的配置来设定值spring.datasource.tomcat.max-wait=10000spring.datasource.tomcat.max-active=50000spring.datasource.tomcat.test-on-borrow=true# JPA (JpaBaseConfiguration, HibernateJpaAutoConfiguration)spring.jpa.database=MYSQL#该配置自动检查实体和数据库表是否一致，如果不一致则会进行更新数据库表，spring.jpa.hibernate.ddl-auto=update#显示sql语句spring.jpa.show-sql=true # EMBEDDED SERVER CONFIGURATION (ServerProperties)#服务器访问端口设置server.port=8080三、Application.java配置，作为spring boot的启动配置@EnableTransactionManagement//开启默认事务管理@SpringBootApplication//spring boot的配置启动容器@ServletComponentScan//servlet的扫描public class Application extends SpringBootServletInitializer {	private static Logger logger = Logger.getLogger(Application.class);			@Override	protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {		return builder.sources(Application.class);	}	public static void main(String[] args) {		SpringApplication.run(Application.class, args);		logger.info("============= SpringBoot Start Success =============");	}}上面的类继承了SpringBootServletInitializer可以把项目打包war文件放入tomcat中进行运行。四、实体层基本配置@Entity@Table(name="sysuser")public class SysUser implements Serializable {	private static final long serialVersionUID = -463669689326264297L;		@Id	@Column(name="SYSUSER_CUID")	private String sysUserCuid;		@Column(name="SYSUSER_NAME")	private String sysUserName;		@Column(name="SYSUSER_PASSWORD")	private String sysUserPassword;		@Column(name="SYSUSER_AGE")	private Integer sysUserAge;	public String getSysUserCuid() {		return sysUserCuid;	}	public void setSysUserCuid(String sysUserCuid) {		this.sysUserCuid = sysUserCuid;	}	public String getSysUserName() {		return sysUserName;	}	public void setSysUserName(String sysUserName) {		this.sysUserName = sysUserName;	}	public String getSysUserPassword() {		return sysUserPassword;	}	public void setSysUserPassword(String sysUserPassword) {		this.sysUserPassword = sysUserPassword;	}	public Integer getSysUserAge() {		return sysUserAge;	}	public void setSysUserAge(Integer sysUserAge) {		this.sysUserAge = sysUserAge;	}		}该配置会在数据库生成对应的表结构。五、dao层配置@Transactionalpublic interface ISysUserDao extends CrudRepository
    
     {	}该dao继承了CrudRepository，其中实现了基本的操作数据库方法，查询、增加、删除、修改、直接接口调用即可。六、controller层调用实现@Controller@RequestMapping(value="sysUser")public class SysUserController {		@Autowired	private ISysUserDao iSysUserDao;		@RequestMapping(value="findAll")	@ResponseBody	public Object findAll(){		return iSysUserDao.findAll();	}		@RequestMapping(value="doInsert")	@ResponseBody	public Object doInsert(){		SysUser sysUser = new SysUser();		sysUser.setSysUserCuid(UUID.randomUUID().toString());		sysUser.setSysUserName("啊啊啊");		sysUser.setSysUserPassword("123456");		sysUser.setSysUserAge(21);		return iSysUserDao.save(sysUser);	}}访问就可得到结果，如下图。
    

七、结果显示

sql打印：
