Spring Boot环境的搭建

傷城~ 2022-04-16 06:29 707阅读 0赞

# 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![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3plYWw5cw_size_16_color_FFFFFF_t_70]

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3plYWw5cw_size_16_color_FFFFFF_t_70 1]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3plYWw5cw_size_16_color_FFFFFF_t_70 2]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3plYWw5cw_size_16_color_FFFFFF_t_70 3]  
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）![在这里插入图片描述][20181118201329996.png]  
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
