Question

我想在Spring项目中使用两个数据库。我正在使用spring-servlet.xml和applicationContext.xml来调用mySql数据库。我怎么能这样做？

这是我的spring-servlet.xml。

#include<stdio.h>
#include<stdlib.h>

int main(void)
{
    FILE* p;
    int a;
    char str[10];

    p = popen("sed -n '$=' loop.c", "r");
    fgets(str, 10, p);                
    a = atoi(str);

    printf("%d", a);
}

    <?xml version="1.0" encoding="UTF-8"?>

    <property name="dataSource" ref="dataSource" />

    <property name="annotatedClasses">
       <list>

            <value>com.startinpoint.proj.PMS.PhaseModule.Phase</value>
            <value>com.startinpoint.proj.PMS.TaskModule.Task</value>
       </list>
    </property>

    <!-- 
    <property name="configLocation">
        <value>hibernate.cfg.xml</value>
    </property>
    -->
    <property name="hibernateProperties">
       <props>
           <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
           <prop key="hibernate.show_sql">false</prop>
       </props>
    </property>
</bean>

请帮我解决这个问题。感谢

正如bigdestroy正确提到的那样，你应该使用多个引用不同数据源的sessionFactory和transactionManager bean。
