Help : spring + JDBC DataSource Why not inject

  //spring 配置
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
  		<property name="driverClass" value="com.mysql.jdbc.Driver" />
  		<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/cdb" />
  		<property name="user" value="root"/>
  		<property name="password" value="123456"/>
  	</bean>
  
  	<bean id="cpaction" class="com.fw.ls.cp.action.CpAction">
  		<property name="dataSource" ref="dataSource"></property>
  	</bean>
  
  //CpAction  
  
          private DataSource dataSource;
  	
  	public String add(){
  		JdbcTemplate jt = new JdbcTemplate(dataSource);
  		String sql = "insert into cp(id,xuhao,dianhua)values(id,?,?)"; 
  		jt.update(sql,"casc","1212");
  		return SUCCESS;
  	}
  
          public void setDataSource(DataSource dataSource) {
  		this.dataSource = dataSource;
  	}
  
  //错误代码
  java.lang.IllegalArgumentException: Property 'dataSource' is required
  setDataSource(DataSource dataSource)并没有进入这个方法就报错了
