使用Derby配置Spring-Boot Autowired JdbcTemplate

我已将gs-relational-data-access-complete的副本克隆到我的工作区,下载了Apache Derby的独立副本并将其启动为“./bin/startNetworkServer”.

我想指出我的Spring Boot项目使用Apache Derby的外部实例,而不是Spring Boot使用的默认嵌入式H2数据库.为了节省时间,我想使用Spring Boot @Autowired注释.

当我发布Derby的新副本时,没有问题：

./bin/startNetworkServer

Sat Nov 21 11:11:06 GMT 2015 : Security manager installed using the Basic server security policy.

Sat Nov 21 11:11:06 GMT 2015 : Apache Derby Network Server – 10.12.1.1 – (1704137) started and ready to accept connections on port 1527

当我启动Spring Boot应用程序时出现问题：

2015-11-21 11:55:07.312 ERROR 11361 — [ main] o.a.tomcat.jdbc.pool.ConnectionPool : Unable to create initial connections of pool.

java.sql.sqlException: Driver:org.apache.derby.jdbc.EmbeddedDriver@db9d03fc returned null for URL:jdbc:derby://10.12.1.1:1527/example1;create=true;user=test1;password=pass1

at org.apache.tomcat.jdbc.pool.PooledConnection.connectUsingDriver(PooledConnection.java:326) ~[tomcat-jdbc-8.0.28.jar:na]

如何在仍然利用Spring Boot @Autowired注释的同时解决此问题的任何帮助将不胜感激.

我的工作区如下：

pom.xml
src/main/java/hello
----Application.java
----Customer.java
src/main/resources
----application.properties

pom.xml中：

application.properties：

spring.datasource.username=test1
spring.datasource.password=pass1

Application.java：

package hello;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.jdbc.core.JdbcTemplate;

import java.util.Arrays;
import java.util.List;
import java.util.stream.Collectors;

@SpringBootApplication
public class Application implements CommandLineRunner {

    private static final Logger log = LoggerFactory.getLogger(Application.class);

    public static void main(String args[]) {
        SpringApplication.run(Application.class, args);
    }

    @Autowired
    JdbcTemplate jdbcTemplate;

解决方法:

这是不匹配的：

Driver:org.apache.derby.jdbc.EmbeddedDriver@db9d03fc returned null 
for URL:jdbc:derby://10.12.1.1:1527/example1;create=true;user=test1;password=pass1

您指定使用Derby嵌入式驱动程序,但您已为Derby提供了数据库的客户端 – 服务器URL.

Derby检测到不匹配并拒绝您的连接尝试.

如果要使用客户端 – 服务器URL,则需要使用Derby ClientDriver类,并且需要在CLAsspATH中使用derbyclient.jar.

如果要使用嵌入式驱动程序,则需要使用嵌入式驱动程序URL,例如

jdbc:derby:example1;create=true;user=test1;password=pass1
