Question

看起来问题很老，但我找不到正确的解决方案。

细节：

的web.xml

    <resource-ref>
    <res-ref-name>jdbc/jndisqldbhello</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
</resource-ref>

context.xml中

<Context>
<Resource name="jdbc/jndisqldbhello"
    auth="Container"
    type="javax.sql.DataSource"
    factory="org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory"
    maxActive="10"
    maxIdle="5"
    maxWait="10000"
    username="root"
    password="123456"
    driverClassName="com.mysql.jdbc.Driver"
    url="jdbc:mysql://localhost:3306/javatest"
    validationQuery="select 1"/>
</Context>

的applicationContext.xml

<jee:jndi-lookup jndi-name="jdbc/jndisqldbhello" id="dataSource" />
    <bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" id="entityManagerFactory">
    <property name="dataSource" ref="dataSource" />
</bean>

的persistence.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_2_0.xsd"
version="2.0">
<persistence-unit name="persistenceUnit" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <properties>
        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
        <property name="hibernate.show_sql" value="true" />
        <property name="hibernate.format_sql" value="true" />
        <property name="hibernate.ejb.naming_strategy" value="org.hibernate.cfg.ImprovedNamingStrategy"/>
    </properties>
</persistence-unit>
</persistence>

无异常地启动TOMCAT，但我对有关NULL定义对象的警告感到困惑：

它开始没有例外，但我相信我会得到它们。如果我加入 persistance.xml

<property name="hibernate.hbm2ddl.auto" value="update"/>

我有例外：

有人可以帮我理解应该如何解决吗？

Answer 1

似乎解决方案在最近的topic。

由于hibernate issue

，我第一次不清楚（不起作用）

如果我在persistence.xml中使用

，我发现一般问题已经解决了

java://comp/env/jdbc/myDatabase

例如

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<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_2_0.xsd"
version="2.0">
<persistence-unit name="persistenceUnit" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <non-jta-data-source>java://comp/env/jdbc/jndisqldbhello</non-jta-data-source>
    <properties>
        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
        <property name="hibernate.connection.datasource" value="java://comp/env/jdbc/jndisqldbhello"/>
        <property name="hibernate.show_sql" value="true" />
        <property name="hibernate.format_sql" value="true" />
        <property name="hibernate.ejb.naming_strategy" value="org.hibernate.cfg.ImprovedNamingStrategy"/>
    </properties>
</persistence-unit>
</persistence>

但如果我添加属性

<property name="hibernate.hbm2ddl.auto" value="create"/>

它不起作用（（。

如果有任何建议请通知我，谢谢。
