SpringBoot技术栈搭建个人博客【项目准备】
原型设计
事实上,我是直接先去找的原型,去参考了一下大概我需要做成什么样子...
前端原型参考
在这里先给大家推荐一个设计网站吧,找素材啊之类的还挺方便的:
站酷:http://www.zcool.com.cn/
所以我在里面找到了我想要的前端原型,大概就像这个样子:
项目搭建
先来介绍一下这次想要使用的一些技术:
- SpringBoot2.04 来编写后台
- Vue 来写页面,准备抛弃一下JSP,虽然现在Vue还啥都不懂,学呗
- MyBatis 用于ORM,喜欢这玩意儿的逆向工程
- RESTful API / JSON 交互
Redis 可能还会使用这个来缓存一下md转换之后的html源码
SpringBoot 工程搭建
SpringBoot 项目搭建过程就不再赘述了,不熟悉的童鞋戳这边:https://www.jianshu.com/p/70963ab49f8c,这里就简单给一下配置信息:
后台肯定是需要加安全验证的,要简单点我可以搞一个拦截器来简单弄弄,也可以用现有的安全框架,这里暂时就不加入这方面的东西了,把基本的弄进来就OK,然后它默认加入的东西不能够支持我们的业务,所以还需要手动添加进一些包:
step 1 项目结构如下:
![](https://images2018.cnblogs.com/blog/1097524/201809/1097524-20180902211746912-561180132.png)
热部署还是要的呀,然后再在【resrouces】下新建一个【banner.txt】文件,修改一下SpringBoot启动的提示信息:
__ __ __
/ __/ /
/ ___ ___ __ __ ____ /' __ _ ____
/' __` __` / / /',__\ , < / /'/\_ ,`
\_/ \_ / / / \ \_ /\__, `\ \` /> <//_/ /_
`\___x___/ \_ \_ \_\/`____ \/\____/ \_ \_/\_/\_ /\____
'/__//__/ /_//_//_/ `/___/> \/___/ /_//_////_/ /____/
/\___/
/__/
下面对这些目录进行一些简要的说明:
- controller:控制器
- dao:实际上这个包可以改名叫mapper,因为里面放的应该是MyBatis逆向工程自动生成之后的mapper类,还是叫dao吧,传统...
- entity:实体类,还会有一些MyBatis生成的example
- generator:MyBatis逆向工程生成类
- interceptor:SpringBoot 拦截器
- service:Service层,里面还有一层impl目录
- util:一些工具类可以放在里面
- mapper:用于存放MyBatis逆向工程生成的.xml映射文件
- static:这个目录存放一些静态文件,简单了解了一下Vue的前后端分离,前台文件以后也需要放在这个目录下面
Step2 然后我使用application.yml文件代替了application.yml,这个东西结构清晰一点儿,反正用哪个都无所谓,配置好就OK了:

RESTful API 设计
为了实现前后端分离,好的RESTful API是离不开的,正好前一段时间学习了这方面的知识,所以决定先来设计一套RESTful API,之前学习的文章链接在这里:https://www.jianshu.com/p/91600da4df95
1)引入Swagger2来构造RESTful API:
既然想弄一下前后端分离,那就彻底一点儿,写后台完全不管前台,前后台的交互靠一套RESTful API和JSON数据来弄,所以需要一个文档来瞅瞅,首先在pox.xml添加相关依赖:
<!--Swagger2支持-->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.2.2</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.2.2</version>
</dependency>
2)创建Swagger2配置类:
在SpringBoot启动类的同级目录下创建Swagger2的配置类【Swagger2】:
/**
* Swagger2 配置类
*
* @author:wmyskxz
* @create:2018-06-14-上午 10:40
*/
@Configuration
@EnableSwagger2
public class Swagger2 {
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("cn.wmyskxz.blog"))
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("zhangyh个人博客RESTful APIs")
.description("原文地址链接:http://blog.didispace.com/springbootswagger2/")
.termsOfServiceUrl("http://blog.didispace.com/")
.contact("@zhangyh")
.version("1.0")
.build();
}
}
这样,就可以在我们启动项目之后,访问http://localhost:8888/swagger-ui.html
地址来查看当前项目中的RESTful风格的API:
package com.springbootblog.controller;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.baomidou.mybatisplus.core.metadata.IPage;
import com.baomidou.mybatisplus.extension.api.ApiController;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.springbootblog.entity.LSysUser;
import com.springbootblog.service.UserService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
*@title : JavaClass
*@author:zyh
*@createDate:2018/8/31 22:31
*
**/
@Api(value = "RESTful API ", description = "RESTful API ")
@RestController
@RequestMapping(value = "/api")
public class UserController extends ApiController {
@Autowired
UserService userService;
@ApiOperation(value = "RESTful API info", produces = "application/json")
@ApiImplicitParams({
@ApiImplicitParam(name = "name", value = "用户名", required = false,
dataType = "String", defaultValue = "zyh")
})
@RequestMapping(value = "userTest", method = RequestMethod.POST)
@ResponseBody
public Object userTest(String name) {
LSysUser lSysUser = userService.selectByPrimaryKey(1L);
return success(lSysUser);
}
/**
*执行 userList 分页查询操作
* @author zhangyh
* @date 2018/9/1 21:57
* @param
* @return
*
*/
@ApiOperation(value = "用户分页列表", produces = "application/json")
@ApiImplicitParams({
@ApiImplicitParam(name = "pageNum", value = "页码", required = false,
dataType = "long", defaultValue = "1"),
@ApiImplicitParam(name = "pageSize", value = "页面大小", required = false,
dataType = "long", defaultValue = "10")
})
@PostMapping(value = "/userList")
public Object findUserPageList(
HttpServletRequest request
, HttpServletResponse response
, Long pageNum
, Long pageSize) {
System.out.println("");
logger.info("");
Page page = new Page(pageNum, pageSize);
Page<LSysUser> pages = new Page<LSysUser>();
pages = userService.findUserPageList(page);
IPage<LSysUser> userListPage = userService.page(new Page<LSysUser>(1, 5), new QueryWrapper<LSysUser>());
System.err.println("total=" + userListPage.getTotal() + ", current list size=" + userListPage.getRecords().size());
userListPage = userService.page(new Page<LSysUser>(1, 5), new QueryWrapper<LSysUser>().orderByDesc("name"));
System.err.println("total=" + userListPage.getTotal() + ", current list size=" + userListPage.getRecords().size());
return success(userListPage);
}
/**
*
* @author zhangyh
* @date 2018/9/1 23:05
* @param []
* @return java.lang.Object
*
*/
@ApiOperation(value = "用户信息保存", produces = "application/json")
@PostMapping(value = "/saveSysUser")
public Object ssaveSysUser() {
LSysUser lSysUser = new LSysUser();
lSysUser = userService.selectByPrimaryKey(1L);
lSysUser.setUserId(null);
userService.saveSysUser(lSysUser);
return success(lSysUser);
}
}
简单介绍一下这些Swagger2的注解吧:
- @ApiOperation:用于给API设置提示信息,就上图中右边显示的那些,默认不写的情况下是value属性,还可以多写一个notes属性,用于详细的描述API,这里就不需要了,都还比较简单;
- @ApiImplicaitParam:用于说明API的参数信息,加了s的注解同理,写了这个之后呢,我们就可以利用Swagger2给我们的信息页面进行测试了,当然这里没有具体实现,也可以来看一下(下图);
这里没有具体实现所以就不足以完成测试,等到后台编写的时候再进行测试吧...
总结
至此呢,我们项目所需要的准备就差不多完成了,想要去做一个东西必须要清楚的知道要的是一个什么东西,这样才能更加好的完成我们的产品,这也是我喜欢和坚信的事情:方向永远比努力重要!(强行有联系..hhhh)
另外一个问题: 我在想文章信息和内容分成了两个表的问题,这样的设计我觉得是没有问题的,但是作为前端并不关心这些数据库的设计,他只要能拿到对象就可以了,在设计 API 的时候,就发现获得一篇文章,需要从三个表(文章信息/文章内容/评论)去获取信息并封装返回前端,这就需要自己在后台另外写一个实体类去封装这些信息,这无疑增加了我们的代码工作量,有没有什么好的方法解决呢?
