無法連接彈簧與mysql

Question

我目前正在從spring文檔工作春天你好樣本。因爲他們正在連接嵌入式數據庫，而不是我想配置mysql數據庫。 來自git的樣本https://github.com/spring-guides/gs-batch-processing.git

請親引導我一個步驟。

將JDBC驅動程序來的pom.xml

<?xml version="1.0" encoding="UTF-8"?> 
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</project> 

這裏是數據庫配置文件

<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-2.5.xsd"> 

    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
     <property name="driverClassName" value="com.mysql.jdbc.Driver" /> 
     <property name="url" value="jdbc:mysql://localhost:3306/spring" /> 
     <property name="username" value="root" /> 
     <property name="password" value="" /> 
    </bean> 

</beans> 

我在這裏缺少什麼？但仍然連接到嵌入式hsql數據庫。看到下面，

試試這個。我正在使用以下屬性連接到Mysql。我可以看到你使用的那些屬性可能適用於postgresql。

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
     <property name="driverClass" value="com.mysql.jdbc.Driver" /> 
     <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/spring" /> 
     <property name="username" value="root" /> 
     <property name="password" value="" /> 
    </bean> 

讓我知道如果它不起作用。
