搭建eclipse版的ssm+maven+tk.mybatis+redis及mybatis+spring多数据源配置集成的demo

前言:我这里搭建好eclipse版的ssm+maven+tk.mybatis+redis及mybatis+spring多数据源配置集成的demo。新手快速上手直接看demo。

最后处提供完整高质量demo!!!

 

准备工作

1、redis下载及配置(demo中有)

(1)下载window或linux版(那本地需要装虚拟机)redis

(2)redis.conf修改(linux版也一样)

  注释:# bind 127.0.0.1

  密码:requirepass 123(自定义密码)

(3)运行,双击redis-startup.bat运行

redis-startup.bat是我自己写的脚本,内容很简单

redis-server.exe redis.conf

2、Eclipse配置mybatis-generator插件

参考:https://blog.csdn.net/u012825737/article/details/79117540

配置好后,右键generatorConfiguration.xml即可生成文件

先来一波完整的配置

3、框架搭建的配置文件

pom.xml

    //get开头的查询slave数据库
	@SuppressWarnings("unchecked")
	@Override
    public List<Book> getBooks() {
		//使用redis,即先到redis中查找是否存在数据,不存在数据再到数据库查询
		List<Book> list = (List<Book>) redisCache.get("list") ;//获取redis缓存
		if(list == null){
			list = bookMapper.selectAll();
			redisCache.set("list", list, 600); //设置redis缓存
		}
        return list;
    }

	//新增到master数据库
	@Override
	public int addBook() {
		Book book = new Book();
		book.setBookDate(new Date());
		book.setBookName("哈哈1");
		book.setBookPrice(30.1);
		return bookMapper.insertSelective(book);
	}

	//新增到Slave数据库
	@Override
	public int addBookSlave() {
		Book book = new Book();
		book.setBookDate(new Date());
		book.setBookName("哈哈2");
		book.setBookPrice(30.2);
		return bookMapper.insertSelective(book);
	}
	
}

其余的就部分是生成的,另外的话不重要了

ok,大体搭建成。。

测试

http://localhost:8080/more-datasource/book/list

http://localhost:8080/more-datasource/book/add

http://localhost:8080/more-datasource/book/add2

效果

redis使用客户端工具查看

所有切换数据源配置在DataSourceInterceptor.java这个文件里动态配置!!!

整理不少时间。。。

下载整合demo

忘记把客户端工具弄进来了。。

redis客户端工具
