Fms-Java版开发实录：02 创建项目

先把项目基础搞好，后边哪里不会就钻研哪里。

启动新Spring项目

今天IDEA更新到了2021.1版，启动时候的图形更加花里胡哨了。正好也借此机会编写这个新项目，顺便好好的复习一下Spring Boot的开发。

老样子，File - New -Project 然后选择 Spring Initializr，配置如下：

  1. Name=fms-java
  2. Type=Maven
  3. Language=Java
  4. Group=cc.conyli
  5. Artifact=fms-java
  6. Package name=cc.conyli.fms
  7. Java=11
  8. Packaging=Jar

我的机器上装的是JDK 11，所以选择Java 11。Spring是最新的2.4.4版。
点击Next进入选择组件的页面，选择如下组件：

  1. Developer Tools - Spring Boot DevTools
  2. Web - Spring Web
  3. Template Engines - Thymeleaf
  4. Security - Spring Security
  5. SQL - Spring Data JPA（含有Hibernate）
  6. SQL - PosetgreSQL Driver
  7. I/O - Validation
  8. I/O - Java Mail Sender
  9. Ops - Spring Boot Actuator

其实有点遗憾的是没有用Redis，这个留待以后功能更加强的话再使用吧。之后配置自动完成。IDEA会显示HELP.md的内容，还是得多读读官方文档才行。

配置数据库连接

spring.datasource.url=jdbc:postgresql://106.54.215.164:5432/fmsjava
spring.datasource.username=*******
spring.datasource.password=*******
spring.datasource.driver-class-name=org.postgresql.Driver
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.show_sql=true
spring.jpa.properties.hibernate.format_sql=true

主要是Hibernate的几个配置，包括自动创建表，显示SQL语句，方便调试。
顺便记录一下，我的VPS上的PostgreSQL是10.16版本。

静态文件

把准备好的放有静态文件css，js，webfonts，img这四个文件夹复制到resources\static\目录下。

启动项目

直接启动项目，日志如下：

从上到下能看到

  1. java启动信息
  2. 没有配置profile，采用默认
  3. Devtools启动
  4. 日志级别可设置为DEBUG以显示更多日志
  5. Spring Data JPA和Hibernate，还有Hikari连接池的启动信息
  6. Tomcat启动
  7. WebApplicationContext启动
  8. 自动加载和重新启动项目的LiveLoader启动
  9. 启动线程池
  10. Thymeleaf的启动信息，此时没有配置模板所以提示找不到任何模板
  11. Spring Security的启动信息，列出了其中全部的过滤器
  12. actuator启动，暴露了两个端点
  13. Tomcat启动完成
  14. 启动Spring DispatcherServlet

之后尝试访问localhost:8080，会进入验证界面，输入用户名user和日志中的密码，可以成功登录，由于目前还没有控制器，因此显示了错误页面。
至此项目启动OK了。马上推送到Github上。

下一步，是编写用户认证登录，为此，先要系统的看一下Thymeleaf的使用。
