spring 和 mybatis 整合的那篇: ssm(2) . 配置文件比ssm(1) 更多, 在做项目的时候, 配置文件是一个让人头大的事情.

那么在spring boot中, 实现相同功能, 需不需要做那么多配置呢.

 

一. 从pom.xml 开始

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <!--tools : joda-time-->

        </plugins>
    </build>


</project>

pom.xml文件, 直观的感觉, 就是非常的短, 非常的少. 简洁

 

二. 配置文件

#配置项目端口和根路径
server:
  port: 8080
  context-path: /boot

spring:
  datasource:
