<think>根据您提供的pom.xml文件，您需要添加MySQLConnector/J9.2.0的依赖。同时，由于您使用的是Java24（根据maven-compiler-plugin配置），请注意MySQLConnector/J9.2.0要求的最低Java版本是8，所以兼容性没有问题。###修改步骤1.**添加MySQLConnector/J9.2.0依赖**：在`<dependencies>`部分添加以下依赖项：```xml<dependency><groupId>com.mysql</groupId><artifactId>mysql-connector-j</artifactId><version>9.2.0</version></dependency>```2.**确保模块化支持**：在`module-info.java`中，我们已经讨论过需要添加`requirescom.mysql.cj;`和驱动服务提供者声明。3.**解决可能存在的依赖冲突**：由于您已经排除了多个依赖中的JavaFX模块，MySQL驱动不包含JavaFX，所以无需额外排除。###修改后的pom.xml（仅显示修改部分）```xml<dependencies><!--已有的依赖...--><!--添加MySQL驱动--><dependency><groupId>com.mysql</groupId><artifactId>mysql-connector-j</artifactId><version>9.2.0</version></dependency><!--其他依赖保持不变--></dependencies>```###完整pom.xml（整合后）```xml<?xmlversion="1.0"encoding="UTF-8"?><projectxmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.example</groupId><artifactId>demo66</artifactId><version>1.0-SNAPSHOT</version><name>demo66</name><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><junit.version>5.10.2</junit.version></properties><dependencies><!--JavaFX依赖--><dependency><groupId>org.openjfx</groupId><artifactId>javafx-controls</artifactId><version>17.0.6</version></dependency><dependency><groupId>org.openjfx</groupId><artifactId>javafx-fxml</artifactId><version>17.0.6</version></dependency><dependency><groupId>org.openjfx</groupId><artifactId>javafx-web</artifactId><version>17.0.6</version></dependency><dependency><groupId>org.openjfx</groupId><artifactId>javafx-swing</artifactId><version>17.0.6</version></dependency><dependency><groupId>org.openjfx</groupId><artifactId>javafx-media</artifactId><version>17.0.6</version></dependency><!--第三方库--><dependency><groupId>org.controlsfx</groupId><artifactId>controlsfx</artifactId><version>11.2.1</version></dependency><dependency><groupId>com.dlsc.formsfx</groupId><artifactId>formsfx-core</artifactId><version>11.6.0</version><exclusions><exclusion><groupId>org.openjfx</groupId><artifactId>*</artifactId></exclusion></exclusions></dependency><dependency><groupId>net.synedra</groupId><artifactId>validatorfx</artifactId><version>0.5.0</version><exclusions><exclusion><groupId>org.openjfx</groupId><artifactId>*</artifactId></exclusion></exclusions></dependency><dependency><groupId>org.kordamp.ikonli</groupId><artifactId>ikonli-javafx</artifactId><version>12.3.1</version></dependency><dependency>极客时间<groupId>org.kordamp.bootstrapfx</groupId><artifactId>bootstrapfx-core</artifactId><version>0.4.0</version></dependency><dependency><groupId>eu.hansolo</groupId><artifactId>tilesfx</artifactId><version>21.0.3</version><exclusions><exclusion><groupId>org.openjfx</groupId><artifactId>*</artifactId></exclusion></exclusions></dependency><dependency><groupId>com.github.almasb</groupId><artifactId>fxgl</artifactId><version>17.3</version><exclusions><exclusion><groupId>极客时间org.openjfx</groupId><artifactId>*</artifactId></exclusion></exclusions></dependency><!--MySQLConnector/J9.2.0--><dependency><groupId>com.mysql</groupId><artifactId>mysql-connector-j</artifactId><version>9.2.0</version></dependency><!--测试依赖--><dependency><groupId>org.junit.jupiter</groupId><artifactId>junit-jupiter-api</artifactId><version>${junit.version}</version><scope>test</scope></dependency><dependency><groupId>org.junit.jupiter</groupId><artifactId>junit-jupiter-engine</artifactId><version>${junit.version}</version><scope>test</scope></dependency></dependencies><build><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>3.13.0</version><configuration><source>24</source><target>24</target></configuration></plugin><plugin><groupId>org.openjfx</groupId><artifactId>javafx-maven-plugin</artifactId><version>0.0.8</version><executions><execution><id>default-cli</id><configuration><mainClass>com.example.demo66/com.example.demo66.HelloApplication</mainClass><launcher>app</launcher><jlinkZipName>app</jlinkZipName><jlinkImageName>app</jlinkImageName><noManPages>true</noManPages><stripDebug>true</stripDebug><noHeaderFiles>true</noHeaderFiles></configuration></execution></executions></plugin></plugins></build></project>```###验证依赖是否正确添加在命令行中运行：```bashmvndependency:tree```检查输出中是否包含：```[INFO]+-com.mysql:mysql-connector-j:jar:9.2.0:compile```###模块信息文件(`module-info.java`)确保您的`module-info.java`包含以下内容：```javamodulecom.example.demo66{requiresjavafx.controls;requiresjavafx.fxml;requiresjavafx.web;requiresjava.sql;requirescom.mysql.cj;//关键：MySQL9.2.0模块名//其他requires...requiresorg.controlsfx.controls;//...其他第三方库的requiresopenscom.example.demo66tojavafx.fxml;exportscom.example.demo66;//如果使用数据库实体类，开放给JavaFX绑定openscom.example.demo66.

驱动依赖**： ```xml <dependency> <groupId>com.mysql</groupId> <artifactId>mysql-connector-j</artifactId> <version>9.2.0</version> </dependency> ``` 2. **添加编译器参数**： ```xml <compilerArgs> <arg>--add-modules</arg> <arg>javafx.controls,javafx.fxml,com.mysql.cj</arg> </compilerArgs> ``` 3. **配置运行时模块**： ```xml <options> <option>--add-modules=com.mysql.cj</option> <option>--add-exports=java.sql/com.mysql.cj.jdbc=ALL-UNNAMED</option> </options> ``` ### 完整的 `module-info.java` 配置 ```java module com.example.demo66 { requires javafx.controls; requires javafx.fxml; requires javafx.web; requires java.sql; // MySQL 9.2.0 模块名 requires com.mysql.cj; requires org.controlsfx.controls; requires com.dlsc.formsfx; requires net.synedra.validatorfx; requires org.kordamp.ikonli.javafx; requires org.kordamp.bootstrapfx.core; requires eu.hansolo.tilesfx; requires com.almasb.fxgl.all; opens com.example.demo66 to javafx.fxml; exports com.example.demo66; // 开放模型包访问权限 opens com.example.demo66.model to javafx.base; // 添加服务提供者声明 provides java.sql.Driver with com.mysql.cj.jdbc.Driver; } ``` ### 验证配置的步骤 1. **刷新 Maven 依赖**： ```bash mvn clean install ``` 2. **检查依赖树**： ```bash mvn dependency:tree | grep mysql ``` 应该输出：`[INFO] +- com.mysql:mysql-connector-j:jar:9.2.0:compile` 3. **验证模块配置**： 在 IntelliJ IDEA 中： - 右键点击项目 → Maven → Reimport - 检查 Project Structure (File → Project Structure) - 在 Modules → Dependencies 中应看到 `mysql-connector-j-9.2.0.jar` - 在 Libraries 中应看到 MySQL 驱动 ### 常见问题解决方案 **问题：仍然找不到模块** 1. 检查驱动版本： ```bash mvn dependency:list | grep mysql ``` 2. 手动添加模块依赖： ```java requires static com.mysql.cj; ``` 3. 在运行配置中添加 VM 参数： ``` --add-modules=com.mysql.cj --add-exports=java.sql/com.mysql.cj.jdbc=ALL-UNNAMED ``` **问题：驱动服务未注册** 在 `module-info.java` 中添加： ```java uses java.sql.Driver; provides java.sql.Driver with com.mysql.cj.jdbc.Driver; ``` ### 数据库连接测试类 ```java package com.example.demo66; import java.sql.Connection; import java.sql.DriverManager; import java.sql.SQLException; public class DatabaseTest { public static void main(String[] args) { String url = "jdbc:mysql://localhost:3306/test?useSSL=false&serverTimezone=UTC"; String user = "root"; String password = "yourpassword"; try (Connection conn = DriverManager.getConnection(url, user, password)) { System.out.println("成功连接到MySQL数据库！"); System.out.println("数据库版本: " + conn.getMetaData().getDatabaseProductVersion()); } catch (SQLException e) { System.err.println("数据库连接失败:"); e.printStackTrace(); // 检查驱动是否加载 try { Class.forName("com.mysql.cj.jdbc.Driver"); System.out.println("MySQL驱动已加载"); } catch (ClassNotFoundException ex) { System.err.println("找不到MySQL驱动类"); ex.printStackTrace(); } } } } ```
