Spring IOC 简单属性注入

<bean name="userDAO" class="com.dao.impl.UserDAOImpl">
   <property name="daoId" value="8"></property>
   <property name="daoStatus" value="good"></property>
  </bean>

 

使用Spring提供的bean：注入连接池

可以用<value>标签

<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
 
  <!-- results in a setDriverClassName(String) call -->
  <property name="driverClassName">
    <value>com.mysql.jdbc.Driver</value>
  </property>
  <property name="url">
    <value>jdbc:mysql://localhost:3306/mydb</value>
  </property>
  <property name="username">
    <value>root</value>
  </property>
  <property name="password">
    <value>masterkaoli</value>
  </property>
</bean>

也可以用value属性：

<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <!-- results in a setDriverClassName(String) call --> <property name="driverClassName" value="com.mysql.jdbc.Driver"/> <property name="url" value="jdbc:mysql://localhost:3306/mydb"/> <property name="username" value="root"/> <property name="password" value="masterkaoli"/> </bean>
