spring - 在tomcat conf文件夹中创建数据源并与spring和hibernate连接时出错

Question

将 spring 和 hibernate 与 tomcat 数据源连接时出现错误，请建议该怎么做

我检查了许多配置文件和 spring jee jndi 资源，但没有找到。

有什么特殊的连接方式吗

Answer 1

好吧，让我完成上面的答案，连同这个

<jee:jndi-lookup id="dataSource"
   jndi-name="name_of_your_datasource"
   expected-type="javax.sql.DataSource" />

你必须像这样配置你的 server.xml ： -

     <Resource auth="Container" driverClassName="oracle.jdbc.OracleDriver" 
    factory="oracle.jdbc.pool.OracleDataSourceFactory" maxActive="20" 
maxIdle="10" maxWait="-1" name="jdbc/oracleDS" password="your pasword" 
type="oracle.jdbc.pool.OracleDataSource" url="your jdbc URL" user="your username"/>.

我希望它能正常工作。随时与我联系。Sunil

Answer 2

You should have something like this in your spring context.xml

<jee:jndi-lookup id="dataSource"
   jndi-name="name_of_your_datasource"
   expected-type="javax.sql.DataSource" />
