Question

目前我的RestController包含以下代码

package be.smartask.api;

import be.smartask.api.model.NumberValue;
import be.smartask.api.model.TextValue;
import be.smartask.api.model.Translations;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.*;


/**
 * @author Glenn Van Schil
 *         Created on 21/01/2016
 */
@CrossOrigin
@RestController
@RequestMapping(path = "/values")
public class Controller {

    @RequestMapping(method = RequestMethod.POST, headers = "Value-Type=text")
    ResponseEntity<?> createAttribute(@RequestBody TextValue value) {
        System.out.println(value.getCode());
        for (Translations.Translation translation : value.getTranslations().getTranslation()) {
            System.out.println(translation.getLang());
            System.out.println(translation.getValue());
        }
        return new ResponseEntity<>(HttpStatus.CREATED);
    }

    @RequestMapping(method = RequestMethod.POST, headers = "Value-Type=number")
    ResponseEntity<?> createAttribute(@RequestBody NumberValue value) {
        System.out.println(value.getMinValue());
        System.out.println(value.getMaxValue());
        return new ResponseEntity<>(HttpStatus.CREATED);
    }
}

这很好用，我可以像这样发布一个NumberValue：

<numberValue id="id" minValue="0" maxValue="10"/>

但是当我将TextValue发布到NumberValue方法

时

<textvalue code="LUXE">
    <translations>
        <translation lang="en">luxury car</translation>
    </translations>
</textvalue>

它仍然有效。它只是将minValue和maxValue留给0,0。

我的问题是：如果正文与我的xsd文件中定义的不完全相同，我怎么能强制执行400：错误请求（或类似的东西）？根据定义，我的意思是xml标记的名称不相同或缺少必需的xs：属性，...

我的xsd文件：

我根据Sheetal Mohan Sharma的回答

将以下内容添加到我的spring配置中

<?xml version="1.0" ?>
<beans xmlns="http://www.springframework.org/schema/beans"

            </list>
        </property>
    </bean>
</beans>

但NumberValue仍然接受TextValue ...

Answer 1

你可以看一下使用jaxb marshaller和unmarshaller 使用消息转换器和jaxmashaller来检查XSD。如果验证失败，则会引发错误，但可能不具体。请查看以下链接。

<bean id="marshallingHttpMessageConverter"
class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter"p:marshaller-ref="jaxb2Marshaller" p:unmarshaller-ref="jaxb2Marshaller" />

<bean id="jaxb2Marshaller">
    <property name="schema" value="classpath:/mySchema.xsd"/>
    <property name="classesToBeBound">
        <list>
            <value>com.xyz.RequestPojo</value>
            <value>com.xyz.ResponsePojo</value>
        </list>
    </property>
</bean>

通过在XSD文件中提供命名空间，我们设法通过API版本化实现了这一目标

config.xml中

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

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd">

    <context:component-scan base-package="be.smartask.api"/>

    <context:annotation-config/>

    <mvc:cors>
        <mvc:mapping path="/**"/>
    </mvc:cors>

    <mvc:annotation-driven>
        <mvc:message-converters>
            <bean id="marshallingHttpMessageConverter"
                  class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter">
                <property name="marshaller" ref="jaxb2Marshaller"/>
                <property name="unmarshaller" ref="jaxb2Marshaller"/>
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>

    <bean id="jaxb2Marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
        <property name="schemas">
          <list>
            <value>classpath:/schema/xsd/v1/smartAsk.xsd</value>
            <value>classpath:/schema/xsd/v2/smartAsk.xsd</value>
          </list>
        </property>
        <property name="packagesToScan">
          <list>
            <value>be.smartask.api.model.smartask.v1</value>
            <value>be.smartask.api.model.smartask.v2</value>
          </list>
        </property>
    </bean>

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/view/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

首先提供模式位置，然后生成xsd对象的包位置，最后使用新创建的Jaxb2Marshaller覆盖marshallingHttpMessageConverter

如果您打算在API中进行一些版本控制，最好提供一个命名空间，以便编组人员知道哪个xsd文件用于哪个包

<xs:schema xmlns="smartask:v1"
       xmlns:xs="http://www.w3.org/2001/XMLSchema"
       xmlns:xsd="http://www.w3.org/2001/XMLSchema"
       xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
       xmlns:annox="http://annox.dev.java.net"
       attributeFormDefault="unqualified"
       elementFormDefault="qualified"
       targetNamespace="smartask:v1"
       jaxb:version="2.1"
       jaxb:extensionBindingPrefixes="annox">

<xs:schema xmlns="smartask:v2"
       xmlns:xs="http://www.w3.org/2001/XMLSchema"
       xmlns:xsd="http://www.w3.org/2001/XMLSchema"
       xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
       xmlns:annox="http://annox.dev.java.net"
       attributeFormDefault="unqualified"
       elementFormDefault="qualified"
       targetNamespace="smartask:v2"
       jaxb:version="2.1"
       jaxb:extensionBindingPrefixes="annox">

在我们的例子中，它是“smartask：v1”和“smartask：v2”
