<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd">
<beans>
     <bean id="triangle" class="bean.Trinangle">
         <property name="points">
             <list>
                 <ref bean="point1"/>
                 <ref bean="point2"/>

     </bean>

     <bean id= "point1" class="bean.Point">
         <property name="x" value="10"/>
         <property name="y" value="20"/>
     </bean>

     <bean id= "point2" class="bean.Point">
         <property name="x" value="10"/>
         <property name="y" value="20"/>
     </bean>

     <bean id= "point3" class="bean.Point">
         <property name="x" value="10"/>
         <property name="y" value="20"/>

</beans>

题：
这是我的XML文件.在第6行我得到错误“他的元素类型的内容”属性“必须匹配”(描述？,meta *,(bean | ref | idref | value | null | list | set | map |
?道具)？)”.”.

解决方法

我认为你实际上并没有创建一个List(如果setPoints预期的话).尝试这样的事情(取自 How to define a List bean in Spring?)：

<?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:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.5.xsd">


 <beans>

 <bean id= "point1" class="bean.Point">
   <property name="x" value="10"/>
   <property name="y" value="20"/>
 </bean>
 <bean id= "point2" class="bean.Point">
   <property name="x" value="10"/>
   <property name="y" value="20"/>
 </bean>
 <bean id= "point3" class="bean.Point">
   <property name="x" value="10"/>
   <property name="y" value="20"/>
 </bean>

<util:list id="pointList" value-type="bean.Point">
    <value>point1</value>
    <value>point2</value>
    <value>point3</value>
</util:list>


 <bean id="triangle" class="bean.Trinangle">
   <property name="points" value="pointList" />
 </bean>

 <bean id= "point1" class="bean.Point">
   <property name="x" value="10"/>
   <property name="y" value="20"/>
 </bean>
 <bean id= "point2" class="bean.Point">
   <property name="x" value="10"/>
   <property name="y" value="20"/>
 </bean>
 <bean id= "point3" class="bean.Point">
   <property name="x" value="10"/>
   <property name="y" value="20"/>
 </bean>
</beans>
