题外话
- 生成UUID方法
(1)java8
UUID.rondom().toString();
(2) hutool
IdUtil.fastSimpleUUID();
(3) mica(基于spring,java8为服务工具集)
StringUtil.getUUID();
正题
-
新建一个springboot工程(此处省略)
-
引入依赖
- hutool工具包
<dependency> <groupId>cn.hutool</groupId> <artifactId>hutool-all</artifactId> <version>4.5.7</version> </dependency>
- json
<!--alibaba--> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.56</version> </dependency>
- 数据库连接池(这里使用阿里巴巴的德鲁伊)
<dependency> <groupId>com.alibaba</groupId> <artifactId>druid-spring-boot-starter</artifactId> <version>1.1.9</version> </dependency>
-
jdbc
<dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency>
-
配置日志文件
- lockback.spring.xml

-
新建application.yml文件
注:编写yml文件时,冒号后面一定要加空格
- 报错1 The server time zone value '�й���ʱ��' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property)
解决方法:
在jdbc url后加上useUnicode=true&characterEncoding=utf8&serverTimezone=UTC
-
报错2 com.mysql.jdbc.Driver 标红
解决方法:
原因:未引入jdbc依赖
<dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency>
-
工程就可以启动啦
-
小菜鸟一枚,请多多指教~
