Spring Boot环境的搭建

什么是Spring Boot？

Spring Boot是由Pivotal团队提供的全新框架，其设计目的是用来简化新Spring应用的初始搭建以及开发过程。该框架使用了特定的方式来进行配置，从而使开发人员不再需要定义样板化的配置。

自己的理解就是spring boot其实不是什么新的框架，它只是默认配置了很多框架的使用方式，就像maven整合了所有的jar包，spring boot整合了所有的框架，需要哪个框架的时候，只需要新建项目的时候勾选相应的框架核心，然后不需要引入额外的Jar包，因为spring boot帮我们做了这件事。

spring boot的特点

• 创建独立的Spring应用程序
• 嵌入的Tomcat，无需部署WAR文件，能直接运行程序
• 简化Maven配置，不需要在pom.xml文件引入过多的jar包
• 自动配置Spring，不需要新建spring的核心配置文件
• 提供生产就绪型功能，如指标，健康检查和外部配置
• 绝对没有代码生成并且对XML也没有配置要求

spring boot的优点

使用spring boot搭建项目，其突出优点就是简单、快速、方便！
平时搭建一个spring web项目的时候可能需要以下步骤：

1.配置web.xml，加载spring核心配置文件和spring mvc的配置文件
2.配置数据库连接、配置spring事务
3.配置加载配置文件的读取，开启注解
4.配置日志文件

…

配置完成之后部署tomcat 调试

…

等一系列操作，可能一不小心就漏了哪个步骤，又得重新检查一遍。。。
而spring boot可以帮你解决传统的spring web项目构建的繁琐步骤，一步到位。
说了这么多，接下来一起来学习怎样使用吧。（它可以应用在快速搭建web项目和为服务）

搭建一个简单的Spring Boot

1. 新建一个全新的project
   springboot2.0以上的版本，jdkz最好选择jdk1.8以上

因为需要访问其官网下载初始化的程序，镜像在国外，所以初始化第一个project的时候很慢，以后在此project新建Model就不用加载如此慢。

2.看一下新建的spring boot的project

3.测试能否不配置繁琐的spring的各种配置文件，能否访问成功
1）
在此目录下新建controller包，包下新建TestController.java

package com.springboot.springboot.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * @author 小思
 * @PackageName:com.springboot.springboot.controller
 * @ClassName: TestController
 * @Description:测试spring boot访问控制器
 * @date 2018/11/18 20:07
 */
@Controller
public class TestController {
    @RequestMapping("/hello")
    public String sayHello(){
        System.out.println("hello spring boot");
        return "index";
    }
}

2）启动服务器，运行项目


环境搭建成功！

解决SpringBoot连接池TOMCAT-JDBC（默认） DBCP或C3P0连接超时异常问题
配置数据源连接池的时候如果没有配置连接检查或者超时回收，造成之后应用通过连接池getConnection时，都可能获取到这些不可用的连接。druid没有上述问题，因为默认有缺省值。

隔多少时间回收废弃连接 一般比minEvictableIdleTimeMillis小
spring.datasource.time-between-eviction-runs-millis=300000
指定运行每个eviction线程时的对象数量
spring.datasource.num-tests-per-eviction-run=3
指定一个空闲连接最少空闲多久后可被清除.
spring.datasource.min-evictable-idle-time-millis=3600000

上面的配置是配置数据源回收连接，只要配置的回收时间小于mysql的超时时间就可以。

spring.datasource.testOnBorrow=true
spring.datasource.validationQuery=SELECT 1

TestOnBorrow检测池里连接的可用性，假如连接池中的连接被数据库关闭了，应用通过连接池getConnection时会重新创建。validationQuery是检查时用的sql语句

SpringBoot1.4.1 需要分别单独配置连接池的配置
比如使用hikari连接池
spring.datasource.type=com.zaxxer.hikari.HikariDataSource
spring.datasource.hikari.minimum-idle=5
