tomcat啟動的時候沒有錯誤,但是進行資料庫操作就會有錯誤。

在網上找了很久  好不容易找到解決方法

出現以上錯誤原因是:資料來源的錯誤配置:

錯誤的jdbc.properties

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/seckill
username=root
password=root

 

錯誤的spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

  <context:property-placeholder location="jdbc.properties"/>

  <bean id="dataSource" destroy-method="close" class="org.apache.commons.dbcp.BasicDataSource" >
        <property name="driverClass" value="${driver}"/>
        <property name="url" value="${url}" />
        <property name="username" value="${username}" />
        <property name="password" value="${password}" />
 </beans>

 

將配置修改為:

jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/seckill
jdbc.username=root
jdbc.password=root

 

spring-dao.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:context="http://www.springframework.org/schema/context"
  xsi:schemaLocation="
    http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.0.xsd">

  <context:property-placeholder location="jdbc.properties"/>

  <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
    <property name="driverClass" value="${jdbc.driver}"/>
    <property name="url" value="${jdbc.url}"/>
    <property name="username" value="${jdbc.username}"/>
    <property name="password" value="${jdbc.password}"/>
  </bean>

</beans>

 

配置完後成功執行。
