Question

I am getting this Exception in Open JPA.

<openjpa-1.2.3-SNAPSHOT-r422266:1295280 nonfatal user error> org.apache.openjpa.persistence.ArgumentException: An error occurred while parsing the query filter "select a from Test a where a.something='D10584707'".

这是我的持久性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 
        http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
    version="1.0">
    <persistence-unit name="MyDataSource">
        <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
        <jta-data-source>jdbc/MyDatasource</jta-data-source>
        <class>com.vo.Test</class>      
    </persistence-unit>

我已经将我的应用程序变形为Web App Archive并且它正在运行。但是，如果我像EJB3那样扭曲相同的应用程序那就是我有问题的地方。

我在WAS 7.0上运行

我解决了我的问题

我在Persistence.xml中缺少RuntimeUnenhancedClasses属性

现在我的持久性XML看起来像这样

<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 
    http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
version="1.0">
<persistence-unit name="MyDataSource">
    <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
    <jta-data-source>jdbc/MyDatasource</jta-data-source>
    <class>com.vo.Test</class>      
    <properties>
    <property name="RuntimeUnenhancedClasses" value="supported"/>
    <property name="openjpa.Log" value="DefaultLevel=WARN, Runtime=INFO, Tool=INFO, SQL=TRACE" />
    </properties>
</persistence-unit>

Answer 2

我遇到了同样的问题并通过更正jpql解决了问题。

是：SELECT c FROM NIMBUSOrganizationUnitEntityObject c WHERE **uuid** = :uuid

至：SELECT c FROM NIMBUSOrganizationUnitEntityObject c WHERE ***c.uuid*** = :uuid

org.apache.openjpa.persistence.ArgumentException：解析查询过滤器时发生错误
