pom.xml如何配置连接oracle

数据库？

你可以在pom.xml文件中添加以下依赖项，以连接Oracle数据库：

<dependency>
  <groupId>com.oracle.database.jdbc</groupId>
  <artifactId>ojdbc8</artifactId>
  <version>18.3.0.0</version>
</dependency>

接着，在application.properties文件中添加以下配置：

spring.datasource.url=jdbc:oracle:thin:@//localhost:1521/orcl
spring.datasource.username=your_username
spring.datasource.password=your_password
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver

其中，你要将上述的your_username和your_password替换成你的Oracle数据库用户名和密码，localhost:1521/orcl则会根据你的实际情况进行修改。

注意，这只是一个示例，实际的 pom.xml 文件可能会有所不同，具体取决于项目的配置和依赖项。

maven toolchains.xml配置

在使用 Maven 构建项目时，如果需要使用不同版本的 JDK 或者其他构建工具，可以通过配置 toolchains.xml 文件来实现。

以下是一个示例的 toolchains.xml 配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<toolchains>
  <toolchain>
    <type>jdk</type>
    <provides>
      <version>1.8</version>
      <vendor>oracle</vendor>
    </provides>
    <configuration>
      <jdkHome>/usr/lib/jvm/java-8-oracle</jdkHome>
    </configuration>
  </toolchain>
  <toolchain>
    <type>maven</type>
    <provides>
      <version>3.6.3</version>
    </provides>
    <configuration>
      <executable>/usr/local/maven-3.6.3/bin/mvn</executable>
    </configuration>
  </toolchain>
</toolchains>

该文件包含了两个工具链的配置，一个是 JDK 工具链，一个是 Maven 工具链。

在使用 Maven 构建项目时，如果需要使用 JDK 1.8，Maven 3.6.3，可以在 pom.xml 文件中添加以下配置：

<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>3.8.1</version>
      <configuration>
        <source>1.8</source>
        <target>1.8</target>
      </configuration>
    </plugin>
  </plugins>
</build>

在执行 Maven 命令时，Maven 会自动查找 toolchains.xml 文件，并根据其中的配置来选择使用哪个工具链。
