SpringBoot使用Oracle11g 怎样在SpringBoot项目中使用Oracle11g数据库

皮卡卡西 人气:0
想了解怎样在SpringBoot项目中使用Oracle11g数据库的相关内容吗，皮卡卡西在本文为您仔细讲解SpringBoot使用Oracle11g的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：SpringBoot项目,Oracle11g数据库，下面大家一起来学习吧。

在SpringBoot项目中使用Oracle11g数据库

具体步骤如下：

1：下载ojdbc6.jar ,随便放个英文目录位置就好

2：命令行下输入下行，注意最后-Dfile 为自己的下载目录

mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0.1.0 -Dpackaging=jar -Dfile=H:\eclpise-workspace\ojdbc6.jar

3：在项目的pom文件中引入下面依赖

<dependency>
     <groupId>com.oracle</groupId>
     <artifactId>ojdbc6</artifactId>
     <version>11.2.0.1.0</version>
 </dependency>

4：在项目的配置文件中写数据库的连接信息，其中，假设Oracle连接ip为127.0.0.1，端口号为1521，数据库为database，用户名为username，密码为password

spring.datasource.driver-class-name=oracle.jdbc.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@127.0.0.1:1521:database
spring.datasource.username=username
spring.datasource.password=password

完成！

SpringBoot 2.0连接Oracle 11g遇到的问题

基本配置信息：

驱动 oracle.jdbc.driver.OracleDriver
连接Url jdbc:oracle:thin:@192.168.112.129:1521:orcl
用户 System
密码 Aa123456

添加驱动包：

这里添加的是ojdbc6包，因为之前在Davinci系统使用ojdbc14时报错了，我使用的Jdk1.8的版本。

ojdbc6.jar比ojdbc14.jar的版本高得多，因为里面的6是指支持jdk1.6 ，而14是指支持jdk1.4。

        <dependency>
            <groupId>com.oracle.database.jdbc</groupId>
            <artifactId>ojdbc6</artifactId>
            <version>11.2.0.4</version>
        </dependency>

创建IDatabasePlatform时出现报错

<!--org.jumpmind.db.platform.JdbcDatabasePlatformFactory-->
Constructor<? extends IDatabasePlatform> construtor = clazz.getConstructor(DataSource.class, SqlTemplateSettings.class);
            IDatabasePlatform platform = construtor.newInstance(dataSource, settings);

解决方案：

经查询，在初始化OracleJdbcSqlTemplate时，由于SpringBoot2.0中使用的是Spring-jdbc-5.0.4，出现了上面的报错信息。

该代码之前使用spring4的spring-jdbc.jar就不会报错，因为spring 5之后就不存在OracleLobHandler这个类了。

由于不想修改代码，继续沿用老版本:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-jdbc</artifactId>
    <version>4.2.6.RELEASE</version>
  </dependency>

以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
