A simple blogging system implemented with Spring Boot + Hibernate + MySQL + Bootstrap4.

SpringBlog

中文开发和部署文档请查看：http://raysmond.com/posts/springblog-guide

SpringBlog is a very simple and clean-design blog system implemented with Spring Boot. It's one of my learning projects to explore awesome features in Spring Boot web programming. You can check my blog site for demo https://raysmond.com.

There's no demo online. Here's the screenshot of my previous blog homepage.

SpringBlog is powered by many powerful frameworks and third-party projects:

• Spring Boot and many of Spring familiy (e.g. Spring MVC, Spring JPA, Spring Secruity and etc)
• Hibernate + MySQL
• HikariCP - A solid high-performance JDBC connection pool
• Bootstrap - A very popular and responsive front-end framework
• Pegdown - A pure-java markdown processor
• ACE Editor - A high performance code editor which I use to write posts and code.
• Redis - A very powerful in-memory data cache server.
• EhCache
• Thymeleaf (Spring MVC)

Development

Before development, please install the following service software:

• MySQL

Edit the spring config profile src/main/resources/application.yml according to your settings.

And start MySQL and Redis first before running the application.

# If you're using Ubuntu server

# Install MySQL
apt-get install mysql-server
service mysql start
mysql -u root -p
>> create database spring_blog;

This is a Gradle project. Make sure Gradle is installed in your machine. Try gradle -v command. Otherwise install in from http://www.gradle.org/. I recommend you import the source code into Intellij IDE to edit the code.

# Start the web application
./gradlew bootRun

Development

How to import the project into Intellij IDEA and run from the IDE?

git clone https://github.com/Raysmond/SpringBlog.git 
cd SpringBlog

bower install 

1. Clone the project
2. Download all dependencies
3. Open the project in Intellij IDEA.
4. Run SpringBlogApplication.java as Java application.
5. Preview: http://localhost:8080 Admin: http://localhost:8080/admin , the default admin account is: admin, password: admin

Lombok is required to run the project. You can install the plugin in Intellij IDEA. Reference: https://github.com/mplushnikov/lombok-intellij-plugin

• Build application jar ./gradlew build, then upload the distribution jar (e.g. build/libs/SpringBlog-0.1.jar) to your remote server.

• Upload application-production.yml to your server and change it according to your server settings.

• Run it (Java8 is a must)

  java -jar SpringBlog-0.1.jar --spring.profiles.active=prod
  # OR with external spring profile file
  java -jar SpringBlog-0.1.jar --spring.config.location=application-production.yml
  

TODO

• Upgrade frontend framework to Bootstrap4
• Replace Jade with Thymeleaf(HTML)
• Frontend building tools, e.g. webpack
• Use hibernate 2nd level cache (EHCache?)
• Markdown preview while editing
• Html editor

除了看官方的教程，主要参考了你这个，欢迎围观

你好，项目导入eclipse中后，实体没有getter、setter方法，造成create service失败

当我添加上getter、setter方法就ok了，是我少导入jar包了吗？

I countinue to code this engine

Errror in starting application

hi Raysmond,

when I started the application with ./gradlew bootRun, it got below error:

2016-07-31 10:08:26.263 [main] DEBUG com.raysmond.blog.Application - Running with Spring Boot v1.3.0.M5, Spring v4.2.7.RELEASE
2016-07-31 10:08:26.457 [main] ERROR o.s.boot.SpringApplication - Application startup failed
Exception in thread "main" java.lang.NoSuchMethodError: org.springframework.core.annotation.AnnotationAttributes.getAliasedStringArray(Ljava/lang/String;Ljava/lang/Class;Ljava/lang/Object;)[Ljava/lang/String;

is it because the Spring core version we used are invalid?

Have you even considered the feature of comment leaving???

empty page -> http://raysmond.com/

spring jpa

spring jpa JpaRepository 查询返回值影射除了List<Object[]>返回以外，可以指定自定义实体么，请教下解决方案

Did your development team discusses about the recommendations for use of Hibernate / JPA?

Hi,

While analyzing some design rules with design tests for persistent classes, I discovered that 91% of a sample of 40 projects from GitHub don't follow the rule about the implementation of the equals/hashCode methods.

These rules are in the documentation of Hibernate (subsection 2.1.5 chapter 2). The first one states that the equals/hashCode methods must be implemented and the second one that their implementation must not access the identifying property. 66% of the projects violate the first rule and 25% violate the second one.

How do you use the framework Hibernate / JPA. I would like to ask two questions:

Do you think these software projects have latent bugs caused by the design rules violations or is the rule unnecessary?

Did your development team discusses about the recommendations for use of Hibernate / JPA?

There are also other rules that they aren't being followed. For more details about the experiment with others results, access: http://tacianosilva.github.io/designtests

Thanks in advance!

Add Index on posts to Accelerate Query

Problem

posts is an important table in SpringBlog and from PostRepository we can find that we always read posts by permalink and post_type.In our test, adding index on posts.permalink and posts.post_type can really improve related querys' performance up to 85%.Therefore, the performance impact for write operations is acceptable under common cases.

Possible Soultion

Add Index on posts.post_type and posts.permalink

关于SLF4J的相关警告信息

在执行bootRun时控制台打印出以下警告：

SLF4J: Class path contains multiple SLF4J bindings. SLF4J: Found binding in [jar:file:/C:/Users/tspoi/.m2/repository/ch/qos/logback/logback-classic/1.1.3/logback-classic-1.1.3.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [jar:file:/C:/Users/tspoi/.m2/repository/org/slf4j/slf4j-log4j12/1.7.12/slf4j-log4j12-1.7.12.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation. SLF4J: Actual binding is of type [ch.qos.logback.classic.util.ContextSelectorStaticBinder]

Declaring project dependencies for logging

在build.gradle里是否声明了不必要的依赖？
尝试注释以下三行后重新执行bootRun，warn相关信息消除。

compile 'org.springframework.boot:spring-boot-starter-log4j:1.3.0.M5'
compile 'org.slf4j:slf4j-api:+'
compile 'org.apache.commons:commons-lang3:+'

关于计算页面响应时间

对@JadeHelper这个注解不是很了解，不知道ViewHelper的生命周期以及是如何调用的，有知道的能解释下吗

你好 请问有没有兴趣来阿里

hello Raysmond

我启动以后，PostService 第68行会直接抛出异常，导致用户创建失败。
这个地方可以改成提示错误信息。

我咋没看见数据库文件，其他人怎么部署成功的？？？

你好，关于HomeController里index方法的问题

往模型里添加的totalPages与page属性在前台好像并没有使用，有什么用吗？谢谢

博客中的图片处理

博主，能问下你是如何处理文章中的图片？

没找到"/authenticate"这个链接的处理呢

SecurityConfig中

.formLogin()
                .loginPage("/signin")
                .permitAll()
                .failureUrl("/signin?error=1")
                .loginProcessingUrl("/authenticate")
                .and()

还有这里：

block content
  .row
    .col-md-4.col-md-offset-4.login-container
      .login-panel
        form.signin-form(method="post",action="/authenticate")
          input(type="hidden", name='_csrf', value='#{_csrf.token}')
          input.form-control(type="text",name="username",placeholder="Email")
          input.form-control(type="password",name="password",placeholder="Password")
          button.btn.btn-primary.btn-block(type="submit") Login

请问这个loginProcessingUrl("/authenticate")的处理方法是哪个呢？没找到

缺少一些css和js文件？

比如
http://localhost:8080/bower_components/bootstrap/dist/css/bootstrap.min.css

找了半天也没有bower_components文件夹
后发现.gitignore文件直接给屏蔽了src/main/resources/static/bower_components
