spring配置文件注意事项

 

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN""http://www.springframework.org/dtd/spring-beans.dtd"><beansxmlns="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-2.5.xsd"><bean id="ds" class="org.apache.commons.dbcp.BasicDataSource"><property name="url"value="jdbc:mysql://localhost:3306/test?characterEncoding=utf-8" /><property name="driverClassName" value="com.mysql.jdbc.Driver" /><property name="username" value="root" /><property name="password" value="mysql" /></bean>.....</beans>

好久么有平配置Springl的applacationContext.xml文件了，今天就鬼使神差的配出了上面那样的就一直报错。结果整了我一下午，原来是<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/dtd/spring-beans.dtd">

和

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="
            http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
            http://www.springframework.org/schema/aop
            http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
            http://www.springframework.org/schema/tx
            http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">

   .......

   .......

</beans>

不能同时配置在一起，二者选其一即可。

因此应该配成这样：

<?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:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"><bean id="ds" class="org.apache.commons.dbcp.BasicDataSource"><property name="url"value="jdbc:mysql://localhost:3306/netctoss?characterEncoding=utf-8" /><property name="driverClassName" value="com.mysql.jdbc.Driver" /><property name="username" value="root" /><property name="password" value="mysql" /></bean>.....</beans>

 

或者这样：

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN""http://www.springframework.org/dtd/spring-beans.dtd"><beans> <bean> </bean> ...... <bean> </bean></beans>
