XML 转换失败 Spring Boot RestTemplate

Question

鉴于这个非常基本的 Spring 引导应用程序：

@SpringBootApplication
public class MyApplication {
    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }

    @Bean
    public RestTemplate restTemplate() {
        return new RestTemplate();
    }
}

具有 Maven 依赖项

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.4.3.RELEASE</version>
</parent>

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <java.version>1.8</java.version>
</properties>

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

以及类型

@XmlRootElement(name = "ICECAT-interface")
public class IceCatResponse {
    private Product product;

    /* getters, setters omitted */
}

@XmlRootElement(name = "Product")
public class Product {

    private int code;

    /* getters, setters omitted */
}

卷曲所需的 URL 产量

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE ICECAT-interface SYSTEM "http://data.icecat.biz/dtd/ICECAT-interface_response.dtd">
<!-- source: Icecat.biz 2017 -->
<ICECAT-interface xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://data.icecat.biz/xsd/ICECAT-interface_response.xsd">
    <Product Code="1"
        HighPic="http://images.icecat.biz/img/norm/high/21900316-8020.jpg"
        ...>
        ...
    </Product>
</ICECAT-interface>

我正在尝试通过 RestTemplate 执行此调用，并希望将结果解析为类型 IceCatResponse:

的 object

ResponseEntity<IceCatResponse> result = this.httpTemplate.exchange(url, HttpMethod.GET, request, IceCatResponse.class);

with request 仅包含身份验证 Header。

这会导致错误消息

Failed to read HTTP message: org.springframework.http.converter.HttpMessageNotReadableException: Could not unmarshal to [class de.mischok.konfigurator.spikeicecat.model.IceCatResponse]: null; nested exception is javax.xml.bind.UnmarshalException - with linked exception: [org.xml.sax.SAXParseException; lineNumber: 2; columnNumber: 10; DOCTYPE ist nicht zulässig, wenn das Feature "http://apache.org/xml/features/disallow-doctype-decl" auf "true" gesetzt ist.]

我认为响应的 DOCTYPE 部分是我的问题，有谁知道，我如何配置 Spring 忽略这部分？

Answer 1

找到一个脏的解决方案：

@Bean
public RestTemplate restTemplate() {
    RestTemplate result = new RestTemplate();

    for (final Iterator<HttpMessageConverter<?>> iterator = result.getMessageConverters().iterator(); iterator.hasNext();) {
        HttpMessageConverter<?> next = iterator.next();
        if (next instanceof Jaxb2RootElementHttpMessageConverter) {
            Jaxb2RootElementHttpMessageConverter jaxbConverter = (Jaxb2RootElementHttpMessageConverter) next;
            jaxbConverter.setSupportDtd(true);
        }
    }

    return result;
}

现在，我的自定义对象的解析已按预期完成，但感觉这个解决方案不像 "Spring-way" 那样...
