SchemaCollection上的多个XSD: schemaElement不能为null？

Question

我正在尝试在我的Web配置中使用SchemaCollection。但是，当我为此添加代码时，我会收到以下错误：

由: java.lang.IllegalArgumentException: schemaElement引起的不能为null！您是运行afterPropertiesSet()还是将其注册为Spring？

这个错误意味着什么？查看弹簧码，是与XSD上的schemaElement相关的东西，但我不能说什么。

惠特schemaCollection，一切都很好。

完全错误：

Did you run afterPropertiesSet() or register this as a Spring bean?

Answer 1

我不知道为什么，但是在将SchemaCollection更改为使用CommonsXsdSchemaCollection之后，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;
}

另外，XSD的顺序在这里注册。如果在嵌套XSD (orders.xsd)之前将父XSD ( ClassPathResource )声明为ClassPathResource，则会收到一些有关“重复命名空间”的错误。

我还需要在XML上添加这个依赖项：

<dependency>
    <groupId>org.apache.ws.xmlschema</groupId>
    <artifactId>xmlschema-core</artifactId>
    <version>2.2.4</version>
</dependency>

以防止使用CommonsXsdSchemaCollection产生的“未找到类”的错误。
