Question

我正在使用Spring + hibernate尝试在Mysql DB上执行查询时应用程序必须提供JDBC连接异常

应用程序上下文有以下条目

<bean id="jdbc" class="org.springframework.jdbc.core.JdbcTemplate">
            <property name="dataSource" ref="appDataSource" />      
</bean>

<bean id="appDataSource" class="org.apache.commons.dbcp.BasicDataSource"
        destroy-method="close">
        <property name="driverClassName" value="org.mariadb.jdbc.Driver" />
        <property name="url" value="jdbc:mariadb://localhost:3306/appdb" />
        <property name="username" value="username" />
        <property name="password" value="password" />
</bean>

JNDI名称为

<jee:jndi-lookup id="appDataSource" jndi-name="java:comp/env/jdbc/Modeling"/>

完成堆栈跟踪

Hibernate配置

<hibernate-configuration>
    <session-factory>
        <mapping resource="service.hbm.xml"/>
    </session-factory>
</hibernate-configuration>

Service.hbm.xml文件

<hibernate-mapping>
   <class name="service.repository.Account"
        table="ACCOUNTS" discriminator-value="null">
        <id name="id" column="id" type="java.lang.Long">
        //all other entry
   </class>
</hibernate-mapping>

Answer 1

执行以下操作 -

1）检查hibernate.cgf.xml（或你的hibernate配置文件）＆amp;确认以下是否正确 -

hibernate.connection.url
hibernate.connection.username
hibernate.connection.password
hibernate.dialect
hibernate.connection.driver_class

2）检查您在standalone.xml（JBoss配置文件）中定义的数据源名称。它应该与您的jndi-name =＆＃34; java： datasource_name ＆＃34匹配;

Answer 2

我假设你的“java：comp / env / jdbc / Modeling”JNDI名称没有指向有效的数据源对象。

Answer 3

从服务器设置中删除Jrebel插件后问题得以解决。一些jrebel如何搞乱配置。

升级后的反叛配置现在工作正常。
