使用Spring MVC和Hibernate 4.2.0.Final的多租户webapp

本文介绍了使用Spring MVC和Hibernate 4.2.0.Final的多租户webapp的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我使用SpringMVC（3.1.3.RELEASE）和Hibernate 4.2.0.Final开发了一个小webapp。我试图将它转换为成为一个多租户应用程序。

类似的话题已经被其他线程所覆盖，但我找不到解决我的问题的明确方案。

我想要实现的是设计一个web应用程序，它能够：

1. 在启动时读取数据源配置（一个包含多个数据源定义的XML文件，它位于WAR文件之外，并且不是应用程序上下文或hibernate配置文件）




2. 为每一个数据源创建一个会话工厂（考虑到每个数据源都是具有不同模式的数据库）。

如何设置会话工厂范围作为会议？ （或者我可以重复使用相同的会话工厂吗？）。




示例：

 客户端URL  -  URL：http://project.com/a/login.html 
客户端b的URL  -  URL：http：// project.com/b/login.html 
  

如果客户端a发出请求，请阅读数据源配置文件并使用该XML文件为客户端a创建会话工厂。



如果客户端b将发送请求，这个过程将重复。 / p>



我在看什么，如何在客户订阅的情况下实现数据源创建，而无需编辑Spring配置文件。它需要自动化。





这是我的代码，我已经完成了。





请任何人告诉我，我需要做些什么修改？





请给出一些示例代码的答案..我在春季和冬眠的世界中是相当新的。

JDBC.properties文件 p>



  jdbc.driverClassName = com.mysql.jdbc.Driver 
 jdbc.dialect = org.hibernate.dialect.MySQLDialect 
 jdbc.databaseurl = jdbc：mysql：// localhost：3306 /物流
 jdbc.username = root 
 jdbc.password=rot@pspl#12 
  



hibernate.cfg.xml文件



 < ？xml version =1.0encoding =UTF-8？> 
<！DOCTYPE hibernate-configuration PUBLIC

< mapping class =pepper.logis.assets.model.Assets/> 
 
< / session-factory> 
< / hibernate-configuration> 
  

谢谢，


解决方案

首先使用tenant_id为Tenant创建一个表，并将其与所有用户相关联。现在，您可以在用户登录并设置会话期间获取此详细信息。




I have developed a small webapp using and SpringMVC(3.1.3.RELEASE) and Hibernate 4.2.0.Final.

I'm trying to convert it to be a multi-tenant application.

Similar topics have been covered in other threads, but I couldn't find a definitive solution to my problem.

What I am trying to achieve is to design a web app which is able to:

1. Read a datasource configuration at startup (an XML file containing multiple datasource definitions, which is placed outside the WAR file and it's not the application-context or hibernate configuration file)

2. Create a session factory for each one of them (considering that each datasource is a database with a different schema).

3. How can i set my session factory scope as session? ( OR Can i reuse the same session factory ?) .

Example:

 Url for client a - URL: http://project.com/a/login.html
 Url for client b - URL: http://project.com/b/login.html

If client "a" make request,read the datasource configuration file and Create a session factory using that XML file for the client "a".

This same process will be repeating if the client "b" will send a request.

What I am looking, how to implement datasource creation upon customer subscription without editing the Spring configuration file. It needs to be automated.

Here is my code ,that i have done so far.

Please anyone tell me,What modifications i need to be made?

Please give an answer with some example code..I am quite new in spring and hibernate world.

Spring.xml

  <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
        destroy-method="close" p:driverClassName="${jdbc.driverClassName}"

        p:url="${jdbc.databaseurl}" 
p:username="${jdbc.username}" p:password="${jdbc.password}" />

    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="configLocation">
            <value>classpath:hibernate.cfg.xml</value>
        </property>

        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">${jdbc.dialect}</prop>
                <prop key="hibernate.show_sql">true</prop>
            </props>
        </property>
    </bean>

<bean id="transactionManager"
        class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />

JDBC.properties File

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.dialect=org.hibernate.dialect.MySQLDialect
jdbc.databaseurl=jdbc:mysql://localhost:3306/Logistics
jdbc.username=root
jdbc.password=rot@pspl#12

hibernate.cfg.xml File

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD//EN"
    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
    <session-factory>
    <mapping class="pepper.logis.organizations.model.Organizaions" />
    <mapping class="pepper.logis.assets.model.Assets" />

</session-factory>
</hibernate-configuration>

Thanks,

解决方案

First create a table for Tenant with tenant_id and associate it with all users.Now, you can fetch this details while the user logs in and set it in session.
