基于SpringBoot从零构建博客网站 - 技术选型和整合开发环境
技术选型和整合开发环境
1、技术选型
博客网站是基于SpringBoot整合其它模块而开发的,那么每个模块选择的技术如下:
- SpringBoot版本选择目前较新的2.1.1.RELEASE版本
- 持久化框架选择Mybatis
- 页面模板引擎选择Freemarker
- 前台框架选择Bootstrap
- 后台框架选择AdminLTE
- 数据库选择Mysql
- 数据库版本管理选择Flyway
技术选型概览图,如下:
2、代码分包
首先确定本工程为sw-blog(即:守望博客),基础包名为:
com.swnote
通过前面同系列的两篇文章可知,本博客网站主要分成3个模块,即用户管理及权限相关模块、文章及专栏等博文相关模块和公共模块。为此这3个模块分别所属的包为auth、blog和common,即:
com.swnote.auth
com.swnote.blog
com.swnote.common
然后每个模块下都是有本模块的controller、service、dao和domain,所以本工程包的结构如下:
3、整合开发环境
根据前面所确定的技术,那么工程的pom文件内容如下:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

application.yml的配置内容如下:
spring:
application:
name: swblog
datasource:
url: ${SWBLOG_DB_URL:jdbc:mysql://localhost:3306/swblog?characterEncoding=utf8}
username: ${SWBLOG_DB_USERNAME:root}
password: ${SWBLOG_DB_PWD:12345678}
driver-class-name: com.mysql.cj.jdbc.Driver
flyway:
clean-disabled: true
enabled: true
locations: classpath:db/migration
baseline-on-migrate: true
freemarker:
suffix: .ftl
content-type: text/html
charset: UTF-8
cache: false
template-loader-path:
- classpath:/templates
mvc:
static-path-pattern: /static/**
server:
port: ${SWBLOG_PORT:80}
mybatis:
mapper-locations: classpath:com/swnote/*/dao/*.xml
type-aliases-package: com.swnote.auth.domain,com.swnote.blog.domain,com.swnote.common.domain
其中配置主要数据库的配置、flyway的配置、freemarker的配置和mybatis的配置,同时还设置4个以“SWBLOG_”开头环境变量,为后期注入值用的,如果还需要有其它的环境变量后期也会慢慢的加。
4、测试
为了检测开发环境是否正确,为此测试从数据库中获取一条数据,然后将数据传递到页面上显示。
利用comm_config表测试,首先往该表中插入一条记录,即:
Dao的Mapper文件:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.swnote.common.dao.ConfigDao">
<sql id="fields">
configId, configValue, description
</sql>
<!-- 根据主键获取配置信息 -->
<select id="retrieve" parameterType="String" resultType="Config">
select <include refid="fields"/> from comm_config where configId = #{configId}
</select>
</mapper>
Service层代码:
package com.swnote.common.service.impl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
import com.swnote.common.dao.ConfigDao;
import com.swnote.common.domain.Config;
import com.swnote.common.service.IConfigService;
/**
* 站点相关配置信息服务类
*
* @author lzj
* @since 1.0
* @date [2019-04-04]
*/
@Transactional
@Service
public class ConfigService implements IConfigService {
@Autowired
private ConfigDao configDao;
@Transactional(propagation = Propagation.NOT_SUPPORTED)
@Override
public Config retrieve(String configId) {
return configDao.retrieve(configId);
}
}
Controller层的测试代码:
package com.swnote.common.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import com.swnote.common.domain.Config;
import com.swnote.common.service.IConfigService;
@Controller
@RequestMapping("/test")
public class TestController {
@Autowired
private IConfigService configService;
@RequestMapping(value = "/index", method = RequestMethod.GET)
public String test(ModelMap model) {
Config config = configService.retrieve("name");
model.addAttribute("config", config);
return "test";
}
}
页面代码:
<!doctype html>
<html>
<head>
<title>测试</title>
<meta charset="utf-8">
</head>
<body>
<h2>${config.configValue}</h2>
</body>
</html>
启动工程后,访问:http://127.0.0.1/test/index,结果如下:
结果是正确的,所以开发环境整合完成了。
