• application configuration file in the spring, this time to build a simple name a.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

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

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

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

       xsi:schemaLocation="http://www.springframework.org/schema/beans

    <bean id="person" class="com.zrm.Person">
        <property name="name" value="zrm"></property>
        <property name="age">
            <value>18</value>
        </property>
    </bean>
</beans>

File encoding problems in the process of building environment were seen in the application file is inconsistent lead to: abnormal contents foreword allowed; and the file can not be found in reading the configuration file, the file does not exist problem.
