org.springframework.beans.NotWritablePropertyException

Spring属性注入异常

错误信息：

Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'brand ' of bean class [com.smart.injection.Car]: 

Bean property 'brand ' is not writable or has an invalid setter method. Did you mean 'brand'?

相关配置文件：

<?xml version="1.0"encoding="UTF-8"?>

<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.xsd">

<!--属性注入-->

    <bean id="car"class="com.smart.injection.Car">

        <property name="brand
"><value>红旗CA72</value></property>

        <property name="maxSpeed"><value>200</value></property>

    </bean>

</beans>

排查过程：

    检查配置文件是否对应、属性名是否正确、是否有网上所说的setter方法。结果均正确，brand是String类型，将其value值“红旗CA72”加上引号依旧报错。

最终解决方案：

    眼尖一点，就会发现，配置文件中<property name="brand
">的brand多了一个空格，删掉多余空格就OK。泪崩啊
