如何配置 TomEE 和 JPA

How configure TomEE and JPA

抱歉我的英语不好,(我是法语 :-D)。 我想为 JPA 使用 TomEE,但我认为我的配置很糟糕。 当我尝试连接到我的数据库时收到异常 (Mysql)。

persistence.xml

<persistence-unit name="elevage" transaction-type="JTA">
    <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
    <jta-data-source>elevage</jta-data-source>
    <non-jta-data-source>elevageUnmanaged</non-jta-data-source>

    <class>com.test.ejb.BeanAnimal</class>

    <properties>

        <property name="openjpa.jdbc.DBDictionary" value="mysql" />
        <property name="openjpa.Log" value="DefaultLevel=WARN, Tool=INFO" />
    </properties>

</persistence-unit>

tomee.xml

<Resource id="elevage" type="DataSource">
    JdbcDriver          com.mysql.jdbc.Driver
    JdbcUrl             jdbc:mysql://localhost:3306/elevage2?useLegacyDatetimeCode=false&amp;serverTimezone=Australia/Sydney&amp;useSSL=false
    UserName            root
    Password            pass
    JtaManaged          true
    DefaultAutoCommit   false
</Resource>

<Resource id="elevageUnmanaged" type="DataSource">
    JdbcDriver          com.mysql.jdbc.Driver
    JdbcUrl             jdbc:mysql://localhost:3306/elevage2?useLegacyDatetimeCode=false&amp;serverTimezone=Australia/Sydney&amp;useSSL=false
    UserName            root
    Password            pass
    JtaManaged          false
</Resource>

异常

AVERTISSEMENT: Unexpected exception from beforeCompletion; transaction will roll back 
<openjpa-2.4.1-r422266:1730418 fatal general error> org.apache.openjpa.persistence.PersistenceException: user lacks privilege or object not found: OPENJPA_SEQUENCE_TABLE {SELECT SEQUENCE_VALUE FROM OPENJPA_SEQUENCE_TABLE WHERE ID = ? FOR UPDATE} [code=-5501, state=42501]

请求是 "SELECT",我想获取数据库中的所有数据。我已查看文档,但问题仍然存在。

谢谢大家的回答! (如果您需要更多文件,请告诉我:-))

折腾了半天终于找到解决办法了,如果能省点时间,就在这里:

2 个配置!

开发中:

tomee.xml不用,需要配置openejb.xml,路径在eclipse 控制台,注意,访问是通过隐藏文件

我的机器路径 (Linux):

 /home/user/eclipse-workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp2/conf/openejb.xml

在文件的底部,您有 "Resource" 部分,配置与 tomee.xml 相同(您可以在此地址找到文档:documentation for configuration tomee.xml

制作中:

我们忘记了openejb.xml,一个配置是相同的但是在tomee.xml

最后,这是我的配置:

persistence.xml

<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="elevage" transaction-type="JTA">
    <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
    <jta-data-source>MyDataBase</jta-data-source>
    <non-jta-data-source>MyDataBaseUnmanaged</non-jta-data-source>

    <class>com.test.ejb.BeanAnimal</class>
    <!-- <class>com.test.ejb.BeanUser</class>-->


    <properties>
        <property name="openjpa.jdbc.DBDictionary" value="mysql" />
        <property name="openjpa.Log" value="DefaultLevel=WARN, Tool=INFO" />
    </properties>

</persistence-unit>

openejb.xml(开发中)和tomee.xml(生产中)

<Resource id="MyDataBase" type="DataSource">
    JdbcDriver com.mysql.jdbc.Driver
    JdbcUrl jdbc:mysql://localhost:3306/elevage?useLegacyDatetimeCode=false&amp;serverTimezone=Australia/Sydney&amp;useSSL=false
    UserName root
    Password pass
    JtaManaged true
</Resource>

<Resource id="MyDataBaseUnmanaged" type="DataSource">
    JdbcDriver com.mysql.jdbc.Driver
    JdbcUrl jdbc:mysql://localhost:3306/elevage?useLegacyDatetimeCode=false&amp;serverTimezone=Australia/Sydney&amp;useSSL=false
    UserName root
    Password pass
    JtaManaged false
</Resource>
