jeesite 4 项目前期部署

1.首先把jeesite4的项目导入idea 

导入之后在web目录下找到pom 文件，右击添加到maven项目。然后就是下载包了。。。。

2.对在application.yml 文件中配置数据源。MySQL 大家都懂的

然后就是初始化数据库了。下面是文档的内容，提示下4.0的要求是MySQL5.7.11以上的。

（我的是5.6的走set global optimizer_switch='derived_merge=off'; 和grant all privileges on jeesite.* to 'jeesite'@'%' identified by 'jeesite';

这两句的时候报错了。第一句是由于没有那个属性，我设置的是index_merge=off 后面那句没有加，但是也初始化数据库了）

3初始化数据库

1、以MySql为例，配置下SQL模式，否则建表的时候可能会出现问题

打开 my.ini 给 [mysqld] 增加如下配置：
sql_mode="ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

2、 创建用户和授权

set global read_only=0;
set global optimizer_switch='derived_merge=off'; 
create user 'jeesite'@'%' identified by 'jeesite';
create database jeesite DEFAULT CHARSET 'utf8mb4' COLLATE 'utf8mb4_unicode_ci';   
grant all privileges on jeesite.* to 'jeesite'@'%' identified by 'jeesite';
flush privileges;

3、 打开文件 /src/main/resources/config/application.yml（v4.0.x：/src/main/resources/config/jeesite.yml） 配置产品和项目名称及JDBC连接

# 产品或项目名称、软件开发公司名称
productName: JeeSite Demo
companyName: ThinkGem

# 产品版本、版权年份
productVersion: V4.1
copyrightYear: 2018

# 数据库连接
jdbc: 

  # Mysql 数据库配置
  type: mysql
  driver: com.mysql.jdbc.Driver
  url: jdbc:mysql://127.0.0.1:3306/jeesite?useSSL=false&useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull
  username: jeesite
  password: jeesite
  testSql: SELECT 1

4.用idea运行InitCoreData.java之前需要设置一个参数否则会报异常

4.用idea运行入口类的时候是会出现失败的情况

需要修改pom文件中idea用compile      eclipes 是provided

		<!-- Spring Boot -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-tomcat</artifactId>
			<!--idea用compile eclipes 是provided-->
			<scope>provided</scope>
			<!--<scope>compile</scope>-->
		</dependency>
