初步分析

由于在项目中需要解析Oracle的XmlType字段,所以除了引入odjbc8.jar外,还要引入如下包:orai18n.jar、xdb6.jar、xmlparserv2.jar(这些包可以从oracle安装文件中找得到)。

其中xmlparserv2.jar的引入会导致容器在加载Spring的xml文件时候出现报错。

I ran into this exact issue while trying to get hibernate and spring working with an oracle XMLType column, and found a better solution than to use JVM arguments as you mentioned.

** Why is it happening? **

The xmlparserv2.jar uses the JAR Services API (Service Provider Mechanism) to change the default javax.xml classes used for the SAXParserFactory, DocumentBuilderFactory and TransformerFactory.

** How did it happen? **

  • 简单释义:因为xmlparserv2.jar中存在META-INF/services目录,里面有制定几个XML解析需要的关键配置,这些配置使用的是oracle特有的,而不是JDK中提供的。

The javax.xml.parsers.FactoryFinder looks for custom implementations by checking for, in this order, environment variables, %JAVA_HOME%/lib/jaxp.properties, then for config files under META-INF/services on the classpath, before using the default implementations included with the JDK (com.sun.org.*).

Inside xmlparserv2.jar exists a META-INF/services directory, which the javax.xml.parsers.FactoryFinder class picks up and uses:

META-INF/services/javax.xml.parsers.DocumentBuilderFactory (which defines oracle.xml.jaxp.JXDocumentBuilderFactory as the default)

META-INF/services/javax.xml.parsers.SAXParserFactory (which defines oracle.xml.jaxp.JXSAXParserFactory as the default)

META-INF/services/javax.xml.transform.TransformerFactory (which defines oracle.xml.jaxp.JXSAXTransformerFactory as the default)

** Solution? **

Switch all 3 back, otherwise you"ll see weird errors. javax.xml.parsers.* fix the visible errors, while the javax.xml.transform.* fixes more subtle XML parsing (in my case, with apache commons configuration reading/writing).

QUICK SOLUTION to solve the application server startup errors:

** JVM Arguments (not great) **

  • 方法一:在JVM启动的时候,通过-D参数强制制定参数值为JDK提供的实现,但是在使用JUnit的RunWith进行单元测试的时候,还是会出现异常,就需要在@BeforeClass中通过System.setProperties方法指定

To override the changes made by xmlparserv2.jar, add the following JVM properties to your application server startup arguments. The java.xml.parsers.FactoryFinder logic will check environment variables first.

-Djavax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl

-Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl

-Djavax.xml.transform.TransformerFactory=com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl

However, if you run test cases using @RunWith(SpringJUnit4ClassRunner.class) or similar, you will still experience the error.

BETTER SOLUTION to the application server startup errors AND test case errors:

Option 1: Use JVM arguments for the app server and @BeforeClass statements for your test cases.

System.setProperty("javax.xml.parsers.DocumentBuilderFactory","com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl");

System.setProperty("javax.xml.parsers.SAXParserFactory","com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl");

System.setProperty("javax.xml.transform.TransformerFactory","com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl");

If you have a lot of test cases, this becomes painful.

  • 方法二(推荐):可以在自己的项目中,添加自定义配置,用于覆盖xmlparserv2.jar里面的配置信息。在自己项目的resources中添加目录(/META-INF/services),并添加下面几个文件

文件一:javax.xml.parsers.DocumentBuilderFactory

内容: com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl

文件二:javax.xml.parsers.SAXParserFactory

内容:com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl

文件三:javax.xml.transform.TransformerFactory

内容:com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl

Option 2: Create your own Service Provider definition files in the compile/runtime classpath for your project, which will override those included in xmlparserv2.jar.

In a maven spring project, override the xmlparserv2.jar settings by creating the following files in the %PROJECT_HOME%/src/main/resources directory:

%PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.parsers.DocumentBuilderFactory (which defines com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl as the default)

%PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.parsers.SAXParserFactory (which defines com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl as the default)

%PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.transform.TransformerFactory (which defines com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl as the default)

These files are referenced by both the application server (no JVM arguments required), and solves any unit test issues without requiring any code changes.
