以下是复合PUpersistence.xml:

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence persistence_1_0.xsd" version="1.0">
<persistence-unit name="compositePu" transaction-type="RESOURCE_LOCAL">
    <provider> org.eclipse.persistence.jpa.PersistenceProvider </provider>
    <jar-file>PU1-entities.jar</jar-file>
    <jar-file>PU2-entities.jar</jar-file>
    <jar-file>PU3-entities.jar</jar-file>
    <properties>
        <property name="eclipselink.composite-unit" value="true" />
    </properties>
</persistence-unit>

下面是各个PU的persistence.xml的结构。它们都遵循类似的结构：

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"
    xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
    <persistence-unit name="PU3" transaction-type="RESOURCE_LOCAL">
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>

    ---- list of fully qualified entity class names ----

    <properties>
        <property name="eclipselink.weaving" value="false" />
        <property name="javax.persistence.validation.group.pre-update" value="none" />
        <property name="eclipselink.target-database" value="MySQL" />
        <property name="eclipselink.ddl-generation" value="none" />
        <property name="eclipselink.persistence-context.flush-mode" value="COMMIT" />
        <property name="eclipselink.persistence-context.close-on-commit" value="true" />
        <property name="javax.persistence.validation.group.pre-persist" value="" />
        <property name="eclipselink.cache.shared.default" value="false" />
        <property name="eclipselink.logging.parameters" value="true" />
        <property name="eclipselink.logging.level" value="FINEST" />
        <property name="eclipselink.logging.parameters" value="true" />
        <property name="eclipselink.cache.shared.default" value="false" />
      </properties>
    </persistence-unit>
</persistence>

Answer 1

警告：这不是正确的答案。问题再次出现！

将eclipselink.cache.shared.default和eclipselink.multitenant.tunternes-share-cache都设置为false Ecelectioned-data Exception。

将eclipselink.Cache.shared.default设置为false并使多租户联接的表继承实体触发了父实体上缓存隔离级别警告中解释的行为的随机出现。然而，请注意，我对随机行为没有任何线索。
