XML_SCHEMA

FGJ: Create:2024/01/13 Update: (2024-10-24)

Intro(XML Schema) #

XML约束就是用于限制XML文件中可以出现的标签以及属性(顺序/格式/类型)文件。DTD约束（约束的粒度比较粗糙）简单/Schame约束（粒度比较细）复杂。

DTD约束 #

<?xml version="1.0" encoding="UTF-8" ?>
<!--引入本地DTD约束-->
<!DOCTYPE persons SYSTEM "person.dtd">

<persons>
    <person name="pOne">
        <name>张三</name>
        <age>18</age>
    </person>
</persons>

<!-- person.dtd -->
<!ELEMENT persons (person+) >
<!ELEMENT person (name, age) >
<!ELEMENT name (#PCDATA) >
<!ELEMENT age (#PCDATA) >

<!--  -->
<!ATTLIST person name CDATA #REQUIRED >

编写规则 #
1. 通过<!ELEMENT 元素名 > 声明可以使用哪些标签.
2. 如果是一个复杂元素，那么需要在元素名后面加一个空格，然后编写()，()里面写该元素中可以出现的子元素。
  2.1 复杂元素中后面的()中的内容，可以通过逗号,分割（必须按顺序出现），也可以通过或符号|分割（必须出现一个）。
  2.2 复杂元素中后面的()中的内容，默认只能出现一次，如果想要出现多次，可以在子元素的名称后面添加符号，(?:只能出现一次),(+:最少一次),(*:可有可无)
3. 如果是一个简单元素，那么需要在元素名后面加一个空格，然后编写(#PCDATA)。
4. 如果是一个属性，通过<!ATTLIST 元素名属性名属性类型属性值 > 进行声明。
  4.1 属性的类型：(CDATA类型：普通的字符串)
  4.2 属性的约束：(#REQUIRED：必须的, #IMPLIED：属性不是必须的, #FIXED value：属性值是固定的)

引入方式 #

引入本地DTD。 <!DOCTYPE 根元素名称 SYSTEM 'DTD文件路径' >

编写规则 #
1. xsd文件的根标签为schema.
2. 在schema中定义属性
  2.1 xmlns="http://www.w3.org/2001/XMLSchema"，元约束。
  2.2 targetNamespace="http://docs.wtfu.site"，指定当前这个schema文件的名称空间。
  2.3 elementFormDefault="qualified"，表示当前文件质量良好。
3. 如果是一个简单元素，直接在<element>元素中定义属性即可。
4. 如果是一个复杂元素，需要增加子元素<complexType>并且在其中增加<sequence>和属性<attribute>。
引入方式 #
1. 通过:冒号的方式起别名，并且指定通过xsi:schemaLocation属性的方式定义资源位置。通过URL一一对应。

    Spring XML Beans Schema, version 3.1
    Authors: Juergen Hoeller, Rob Harrop, Mark Fisher, Chris Beams

    This defines a simple and consistent way of creating a namespace
    of JavaBeans objects, managed by a Spring BeanFactory, read by
    XmlBeanDefinitionReader (with DefaultBeanDefinitionDocumentReader).

    This document type is used by most Spring functionality, including
    web application contexts, which are based on bean factories.

    Each "bean" element in this document defines a JavaBean.
    Typically the bean class is specified, along with JavaBean properties
    and/or constructor arguments.

    A bean instance can be a "singleton" (shared instance) or a "prototype"
    (independent instance). Further scopes can be provided by extended
    bean factories, for example in a web environment.

    References among beans are supported, that is, setting a JavaBean property
    or a constructor argument to refer to another bean in the same factory
    (or an ancestor factory).

    As alternative to bean references, "inner bean definitions" can be used.
    Singleton flags of such inner bean definitions are effectively ignored:
    inner beans are typically anonymous prototypes.

    There is also support for lists, sets, maps, and java.util.Properties
    as bean property types or constructor argument types.

    If one or more of the specified profiles are active at time of parsing, the <beans>
    element will be parsed, and all of its <bean> elements registered, &lt;import&gt;
    elements followed, etc.  If none of the specified profiles are active at time of
    parsing, then the entire element and its contents will be ignored.

    If a profile is prefixed with the NOT operator '!', e.g.

    Controls whether bean properties are "autowired".
    This is an automagical process in which bean references don't need
    to be coded explicitly in the XML bean definition file, but rather the
    Spring container works out dependencies.

    There are 4 modes:

    1. "no"
    The traditional Spring default. No automagical wiring. Bean references
    must be defined in the XML file via the <ref/> element (or "ref"
    attribute). We recommend this in most cases as it makes documentation
    more explicit.

    Note that this default mode also allows for annotation-driven autowiring,
    if activated. "no" refers to externally driven autowiring only, not
    affecting any autowiring demands that the bean class itself expresses.

    2. "byName"
    Autowiring by property name. If a bean of class Cat exposes a "dog"
    property, Spring will try to set this to the value of the bean "dog"
    in the current container. If there is no matching bean by name, nothing
    special happens.

    3. "byType"
    Autowiring if there is exactly one bean of the property type in the
    container. If there is more than one, a fatal error is raised, and
    you cannot use byType autowiring for that bean. If there is none,
    nothing special happens.

    4. "constructor"
    Analogous to "byType" for constructor arguments. If there is not exactly
    one bean of the constructor argument type in the bean factory, a fatal
    error is raised.

    Note that explicit dependencies, i.e. "property" and "constructor-arg"
    elements, always override autowiring.

    Note: This attribute will not be inherited by child bean definitions.
    Hence, it needs to be specified per concrete bean definition.
