server:
  port: 8080
  tomcat:
    uri-encoding: UTF-8

spring boot更多预置参数请参考：

https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html

1.2 应用配置

2. Spring Boot中使用数据库

2.1 MySQL与JPA

JPA(Java Persistence API)是Java EE的持久化标准规范。Spring Boot可以使用JPA实现对数据库操作。JPA将POJO(Plain Ordinary Java Object)通过ORM(Object-Relational Mapping)持久化到数据库中。

JPA官方介绍：http://docs.oracle.com/javaee/6/tutorial/doc/bnbpz.html

JPA 教程：https://www.tutorialspoint.com/jpa/index.htm

JPA和MySQL依赖配置：

2.2 MyBatis与Spring Boot集成

2.3 Redis

2.4 MongoDB

2.5 Neo4j
