SpringBoot运用Spring-Data-Jpa实现CRUD实现

 

下面来演示下SpringBoot下,实用Spring-Data-Jpa来实现CRUD操作，视图层采用Freemarker

这里我们先把application.properties修改成application.yml 主流格式

内容也改成yml规范格式：

 1 server:
 2   port: 8888
 3   context-path: /
 4    
 5 helloWorld: spring Boot\u4F60\u597D
 6    
 7 msyql:
 8    jdbcName: com.mysql.jdbc.Driver
 9    dbUrl: jdbc:mysql://localhost:3306/db_diary
10    userName: root
11    password: 123456
12  
13 spring:
14    datasource:
15       driver-class-name: com.mysql.jdbc.Driver
16       url: jdbc:mysql://localhost:3306/db_book
17       username: root
18       password: passwd
19    jpa:
20      hibernate.ddl-auto: update
21      show-sql: true
