与Java Spring，Maven，Oracle，Hibernate的连接

Question

I'm trying to connect my maven project to an oracle database using spring and hibernate, this error is still showing up after many attempts to fix it, would you guys mind checking this out and guide me on what might be wrong?

Error in CMD (Picture)

23:07:45,676 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/SpringMVC].[SpringMVC]] (http--127.0.0.1-8088-1) Servlet.service() para servlet SpringMVC lanz¾ excepci¾n: oracle.net.ns.NetException: Got minus one from a read call

My Application context: ApplicationContext.xml (picture)

<bean id="dataSource" class="oracle.jdbc.pool.OracleDataSource">
    <property name="dataSourceName" value="ds" />
    <property name="URL"
        value="jdbc:oracle:thin:@127.0.0.1:8080:test" />
    <property name="user" value="system" />
    <property name="password" value="3123312257" />
</bean>

My dependecy of Oracle

<dependency>
    <groupId>com.oracle</groupId>
    <artifactId>ojdbc7</artifactId>
    <version>12.1.0.2</version>
</dependency>

My aplication.properties:

# create and drop tables and sequences, loads import.sql
spring.jpa.hibernate.ddl-auto=create-drop

spring.datasource.url=jdbc:oracle:thin:@127.0.0.1:8080:test
spring.datasource.username=system
spring.datasource.password=3123312257
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver

Answer 1

The connection parameter for host "localhost" and the port "8080" are really correct?

Please verify once.

Below code works fine for me. you can use the same and check if there is an oracle issue or your side.

public static void main(String[] args) throws ClassNotFoundException {
try {
Connection connection = null;

String serverName = "127.0.0.1"; //http://127.0.0.1:8080/apex
String portNumber = "1521";
String sid = "xe"; //xe

String url = "jdbc:oracle:thin:@" + serverName + ":" + portNumber + ":" + sid;

String username = "system";
String password = "password";

connection = DriverManager.getConnection(url, username, password);

Statement stmt = connection.createStatement();

ResultSet rset = stmt.executeQuery("select * from employee");

while (rset.next()) 
{
System.out.println(rset.getString(1));
System.out.println(rset.getString(2));
}
stmt.close();

} catch (Exception e) {
System.out.println("Hai " + e);
}
}

Answer 2

将端口更新为1521后，您可能需要更新tnsnames.ora中的端口（可能放在oracle \\ product \\ {version} \\ client_1 \\ network \\ ADMIN中）。
