Question

我是Spring社交新手，我正在创建一个与facebook和twitter互动的应用程序。我已经通过使用twitter4j做了twitter部分，但是对于facebook，我正在尝试使用spring facebook，但是我很难用它来例外。

org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/social/spring-social-facebook.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

Answer 1

我解决了这个问题，实际上我使用了错误的弹簧依赖。

    <dependency>
        <groupId>org.springframework.social</groupId>
        <artifactId>spring-social-web</artifactId>
        <version>${spring-social.version}</version>
    </dependency>

但春季facebook的正确依赖是。

    <dependency>
        <groupId>org.springframework.social</groupId>
        <artifactId>spring-social-facebook</artifactId>
        <version>${spring-social.version}</version>
    </dependency>

Answer 2

似乎facebook架构不再可用或已删除，保留一个本地xsd文件，并在您的上下文中引用它，如此处所述 https://github.com/spring-projects/spring-social-facebook/issues/79

在classpath（src / main /）文件夹中创建一个文件夹xml，并添加一个xsd文件作为spring-social-facebook-1.1.xsd，内容如下

  <?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns="http://www.springframework.org/schema/social/facebook"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    targetNamespace="http://www.springframework.org/schema/social/facebook">

    <xsd:element name="config">
        <xsd:complexType>
            <xsd:attribute name="app-id" use="required" type="xsd:string" />
            <xsd:attribute name="app-secret" use="required" type="xsd:string" />
            <xsd:attribute name="app-namespace" use="optional" type="xsd:string" />
        </xsd:complexType>
    </xsd:element>

</xsd:schema>

并在您的applicationContext.xml中，参考此XSD

http://www.springframework.org/schema/social/facebook classpath:xml/spring-social-facebook-1.1.xsd

Spring application-context.xml --- java.io.FileNotFoundException：http：//www.springframework.org/schema/social/spring-social-facebook.xsd
