【问题描述】:
我的项目中有Spring 配置。其中 context.xml 由我用 Java 动态重写。我的问题是,为什么重写文件后bean命名空间URL没有出现?
重写前我的 context.xml 文件:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:util="http://www.springframework.org/schema/util"
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-2.0.xsd
http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2..xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd ">
<!-- <context:annotation-config /> -->
<bean class="org.springframework.ws.client.core.WebServiceTemplate" id="webServiceTemplate">
<constructor-arg ref="messageFactory"/>
<property name="marshaller" ref="xmlbeansMarshaller"/>
<property name="unmarshaller" ref="xmlbeansMarshaller"/>
<property name="defaultUri">
<value>https://google.com</value></property>
</bean></beans>
我重写 context.xml 的 Java 代码:
DocumentBuilderFactory docFactory1 = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder1 = docFactory1.newDocumentBuilder();
Document doc1 = docBuilder1.parse(afilePath);
Node incIncident1 = doc1.getElementsByTagName("beans").item(0);
NodeList beanList = incIncident1.getChildNodes();
NodeList beanlist1 = beanList.item(25).getChildNodes();
List <Map<String, String>> aunitDetails = be.extendedData.get("uicdsDetails");
if (aunitDetails != null) {
for (int i = 0; i < aunitDetails.size(); i++) {
Map<String, String> unitLogDetails = aunitDetails.get(i);
NodeList beanList2= beanlist1.item(7).getChildNodes();
if (unitLogDetails.get("uURL") != null) {
beanList2.item(0).setTextContent(unitLogDetails.get("uicdsURL"));
} else {
beanList2.item(0).setTextContent("https://google.com");
}
TransformerFactory transformerFactory1 = TransformerFactory.newInstance();
Transformer transformer1 = transformerFactory1.newTransformer();
System.out.println(doc);
DOMSource source1 = new DOMSource(doc1);
StreamResult result1 = new StreamResult(new File(afilePath));
transformer1.transform(source1, result1);
}
}
context.xml 被重写后:
<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns:context="http://www.springframework.org/schema/context"
xmlns:util="http://www.springframework.org/schema/util"
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-2.0.xsd
http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2..xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd ">
<!-- <context:annotation-config /> -->
<bean class="org.springframework.ws.client.core.WebServiceTemplate" id="webServiceTemplate">
<constructor-arg ref="messageFactory"/>
<property name="marshaller" ref="xmlbeansMarshaller"/>
<property name="unmarshaller" ref="xmlbeansMarshaller"/>
<property name="defaultUri">
<value>https://google.com</value></property>
</bean>
</beans>
这里重写的 context.xml 文件缺少 XML 命名空间
xmlns="http://www.springframework.org/schema/beans"
为什么在重写时这个xmlns 不见了?
