Question

我有一个部署到Weblogic 12c容器的spring boot web应用程序。

我有弹簧MVC映射processEvent(@Valid @RequestBody UpstreamEvent event)

我的weblogic.xml文件包含：

<container-descriptor>
    <prefer-web-inf-classes>false</prefer-web-inf-classes>
    <prefer-application-packages>
        <package-name>com.google.*</package-name>
        <package-name>javax.persistence.*</package-name>
        <package-name>javax.persistence.spi*</package-name>
        <package-name>org.apache.commons.*</package-name>
        <package-name>org.hibernate.*</package-name>
        <package-name>javax.validation.*</package-name>
        <package-name>org.jboss.logging.*</package-name>
        <package-name>com.fasterxml.classmate.*</package-name>
        <package-name>org.joda.*</package-name>
        <package-name>org.springframework.*</package-name>
        <package-name>org.slf4j.*</package-name>
        <package-name>ch.qos.logback.*</package-name>
        <package-name>org.objectweb.asm.*</package-name>
        <package-name>antlr.*</package-name>
        <package-name>javassist.*</package-name>
    </prefer-application-packages>
</container-descriptor>

当请求进入时，输入得到验证，我得到例外情况如下：

它似乎是一些类路径问题，即使我更喜欢hibernate验证器及其依赖项。

当我的应用程序部署到Tomcat时，我没有看到这些异常。

为什么我得到例外？

Answer 1

对我来说，我可以通过在weblogic.xml中添加以下内容来使其工作

<wls:prefer-application-resources>
<wls:resource-name>META-INF/services/javax.persistence.spi.PersistenceProvider</wls:resource-name>
</wls:prefer-application-resources>
