Question

我有一个xml文件可以满足我的需要，但是它有很多重复的代码。例如-用户名和密码是xml文件中每个bean的一部分。我使用parentBean id创建了下面的文件，希望可以重用子bean中的所有内容。但是我遇到The content of element type "bean" must match错误。

<?xml version="1.0" encoding="UTF-8"?>

您需要在父bean上指定属性名称。要合并父级和子级bean的映射，请在beans元素上设置属性default-merge="true"。

即

<?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"
    default-merge="true">
   <bean id="parentBean" class="com.dataloader.ProcessRunner" abstract="true">
   <description>Parent bean.</description>
     <property name="configOverrideMap">
       <map>
         <entry key="sfdc.debugMessages" value="true" />
         <entry key="sfdc.debugMessagesFile" value="C:\DLTest\accountExportSoapTrace.log" />
         <entry key="sfdc.endpoint" value="https://test.com" />
         <entry key="sfdc.username" value="test" />
         <entry key="sfdc.password" value="5b69d70a1dd974a21ecf64595ac02596f0c7c" />
         <entry key="process.encryptionKeyFile" value="D:\SF\dataLoader.key" />
         <entry key="sfdc.timeoutSecs" value="600" />
       </map>
     </property>
   </bean>
   ... rest of the applicationContext

重用bean的XML片段
