前言

上次介绍了Spring Boot中Mybatis的简单整合，本篇深入来结合通用Mapper、Mybatis Geneator以及分页PageHelper来打造适合企业开发的模板框架。

项目框架还是跟上一篇一样使用Spring Boot的ace后端模板，不过最近在使用vue，所以前端引用了vue进来改写，代码变得更加简洁。

项目配置：

Spring Boot： 1.5.9.RELEASE
Maven： 3.5
Java： 1.8
Thymeleaf： 3.0.7.RELEASE
Vue.js： v2.5.11

数据源依赖

这里我们还是使用阿里巴巴的druid来当数据库连接池，发现这个有对应的监控界面，我们可以开启。
druid官方文档：https://github.com/alibaba/druid/wiki/常见问题

<dependency>
	<groupId>mysql</groupId>
	<artifactId>mysql-connector-java</artifactId>
</dependency>

<dependency>
	<groupId>com.alibaba</groupId>
	<artifactId>druid</artifactId>
	<version>1.0.19</version>
</dependency>

对应的application.properties配置：

## 数据库访问配置
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driver-class-name = com.mysql.jdbc.Driver
spring.datasource.url = jdbc:mysql://localhost:3306/spring?useUnicode=true&characterEncoding=utf-8
spring.datasource.username = root
spring.datasource.password = root

# 下面为连接池的补充设置，应用到上面所有数据源中
# 初始化大小，最小，最大
spring.datasource.initialSize=5
spring.datasource.minIdle=5
spring.datasource.maxActive=20
# 配置获取连接等待超时的时间
spring.datasource.maxWait=60000
# 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒
spring.datasource.timeBetweenEvictionRunsMillis=60000
# 配置一个连接在池中最小生存的时间，单位是毫秒
spring.datasource.minEvictableIdleTimeMillis=300000
spring.datasource.validationQuery=SELECT 1 FROM DUAL
spring.datasource.testWhileIdle=true
spring.datasource.testOnBorrow=false
spring.datasource.testOnReturn=false
# 打开PSCache，并且指定每个连接上PSCache的大小
spring.datasource.poolPreparedStatements=true
spring.datasource.maxPoolPreparedStatementPerConnectionSize=20
# 配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙
spring.datasource.filters=stat,wall,log4j
# 合并多个DruidDataSource的监控数据
#spring.datasource.useGlobalDataSourceStat=true

对应的bean配置：
