spring bean.xml文件p标签使用报错的解决

bean.xml文件p标签使用报错

The prefix "p" for attribute "p:某属性" associated with an element type "bean" is not bound.

某元素属性未捆绑，直接点击添加p的命名空间，或者手动在<beans>里面添加一行约束

xmlns:p="http://www.springframework.org/schema/p"

spring 的xml配置使用p标签简化

1、常见配置

比如配置数据源 读取properties

<!-- 配置阿里巴巴数据源 -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
init-method="init" destroy-method="close">
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="filters" value="wall,stat,log4j" />
<property name="maxActive" value="300" />
<property name="initialSize" value="1" />
<property name="maxWait" value="60000" />
<property name="minIdle" value="1" />
<property name="timeBetweenEvictionRunsMillis" value="3000" />
<property name="minEvictableIdleTimeMillis" value="300000" />
<property name="validationQuery" value="SELECT 'x'" />
<property name="testWhileIdle" value="true" />
<property name="testOnBorrow" value="false" />
<property name="testOnReturn" value="false" />
<property name="poolPreparedStatements" value="true" />
<property name="maxPoolPreparedStatementPerConnectionSize"
value="20" />
</bean>

可以配置如下

< bean id="dataSource"  class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"
 p:driverClassName="org.gjt.mm.MySQL.Driver"  p:url="jdbc:mysql://127.0.0.1:3306/easyjf-bbs" p:username="root" p:password="mysql" />
< /beans>

p表示对该bean里面的属性进行注入，格式为p:属性名=注入的对象

效果与在bean里面使用<property>标签一样
