SchemaCollection 上的多个 XSD：schemaElement 不能为 null？
Multiple XSDs on SchemaCollection: schemaElement must not be null?
我正在尝试在我的 Web 服务配置中使用 SchemaCollection。但是当我为此添加代码时，我收到此错误：
Caused by: java.lang.IllegalArgumentException: schemaElement must not be null! Did you run afterPropertiesSet() or register this as a Spring bean?
这个错误是什么意思？在Spring code上看是和XSD上的schemaElement有关系，但我说不出是什么。
没有 schemaCollection，一切正常。

我不知道为什么，但是将 SchemaCollection 更改为使用 CommonsXsdSchemaCollection 后，错误消失了：
@Bean
public XsdSchemaCollection schemaCollection() {
CommonsXsdSchemaCollection commonsXsdSchemaCollection = new CommonsXsdSchemaCollection(
new ClassPathResource("xsd/po.xsd"),
new ClassPathResource("xsd/orders.xsd"));
commonsXsdSchemaCollection.setInline(true);
return commonsXsdSchemaCollection;
}
此外，XSDs 的顺序在此处注册很重要。如果您在嵌套的 XSD (po.xsd) 之前将父级 XSD (orders.xsd) 声明为 ClassPathResource，您将收到一些关于 "namespace duplicated" 的错误.
我还需要在 XML:
上添加这种依赖
<dependency>
<groupId>org.apache.ws.xmlschema</groupId>
<artifactId>xmlschema-core</artifactId>
<version>2.2.4</version>
</dependency>
防止因使用 CommonsXsdSchemaCollection.
