介绍下mysql数据库读写分离在spring,hibernate框架下的配置。
1.mysql连接配置文件jdbc.properties
master.*.*表示主数据库连接参数，负责增，删，改；
slave.*.*表示从数据库连接参数，只负责读取；

jdbc.properties
Java代码
master.jdbc.driverClassName=com.mysql.jdbc.Driver
master.jdbc.url=********
master.jdbc.username=********
master.jdbc.password=********

slave.jdbc.driverClassName=com.mysql.jdbc.Driver
slave.jdbc.url=********
slave.jdbc.username=********
slave.jdbc.password=********

[java] view plaincopyprint?
  1. master.jdbc.driverClassName=com.mysql.jdbc.Driver  
  2. master.jdbc.url=********  
  3. master.jdbc.username=********  
  4. master.jdbc.password=********  
  5.   
  6. slave.jdbc.driverClassName=com.mysql.jdbc.Driver  
  7. slave.jdbc.url=********  
  8. slave.jdbc.username=********  
  9. slave.jdbc.password=********  
master.jdbc.driverClassName=com.mysql.jdbc.Driver
master.jdbc.url=********
master.jdbc.username=********
master.jdbc.password=********

slave.jdbc.driverClassName=com.mysql.jdbc.Driver
slave.jdbc.url=********
slave.jdbc.username=********
slave.jdbc.password=********
把**改成你所需的连接参数；

2.配置AOP切面类 DataSourceAdvice.java
Java代码
import java.lang.reflect.Method;
import org.springframework.aop.AfterReturningAdvice;
import org.springframework.aop.MethodBeforeAdvice;
import org.springframework.aop.ThrowsAdvice;

import com.company.datasource.DataSourceSwitcher;

public class DataSourceAdvice implements MethodBeforeAdvice, AfterReturningAdvice, ThrowsAdvice {
    // service方法执行之前被调用
    public void before(Method method, Object[] args, Object target) throws Throwable {
        System.out.println("切入点: " + target.getClass().getName() + "类中" + method.getName() + "方法");
        if(method.getName().startsWith("add")
            || method.getName().startsWith("create")
            || method.getName().startsWith("save")
            || method.getName().startsWith("edit")
            || method.getName().startsWith("update")
            || method.getName().startsWith("delete")
            || method.getName().startsWith("remove")){
            System.out.println("切换到: master");
            DataSourceSwitcher.setMaster();
        }
        else  {
            System.out.println("切换到: slave");
            DataSourceSwitcher.setSlave();
        }
    }

    // service方法执行完之后被调用
    public void afterReturning(Object arg0, Method method, Object[] args, Object target) throws Throwable {
    }

    // 抛出Exception之后被调用
    public void afterThrowing(Method method, Object[] args, Object target, Exception ex) throws Throwable {
        DataSourceSwitcher.setSlave();
        System.out.println("出现异常,切换到: slave");
    }

}
