在spring编写引用第三方bean时我遇到的问题  
![在这里插入图片描述][44626866b9334ba2821efa38469c8139.png]

### 错误提示 ###

Error creating bean with name ‘druidDataSource’ defined in class path resource \[applicationContext.xml\]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type ‘java.lang.String’ to required type ‘java.sql.Driver’ for property ‘driver’; nested exception is java.lang.IllegalStateException: Cannot convert value of type ‘java.lang.String’ to required

### 解决办法 ###

检查自己的配置文件

<context:property-placeholder location="classpath:db.properties"></context:property-placeholder>
        
        <bean id="druidDataSource" class="com.alibaba.druid.pool.DruidDataSource">
            <property name="url" value="${jdbc.url}"/>
    		**<property name="driver" value="${jdbc.driver}"/>**
            <property name="name" value="${jdbc.username}"/>
            <property name="password" value="${jdbc.password}"/>
        </bean>
    </beans>

发现自己写的  
\*\*< property name=“driver” value=“$\{jdbc.driver\}”/>\*\*中的name里面的值写错了  
在更改为driverClassName后,运行成功

< property name="driverClassName" value="${jdbc.driver}"/>
