如果我 运行 使用 spring boot 2.2.7.RELEASE 上面的代码，它工作得很好——没有例外！！
2 天后，我想到在本地主机上配置一个 mysql 数据源。同一个程序 运行 没问题（使用 spring boot 2.3.0.RELEASE）但是这次它使用了 mysql 数据源。
<dependency>
<groupId>mysql</groupId>

<scope>runtime</scope>

spring boot 2.3.0.RELEASE 中的 oracle jdbc 驱动程序发生了什么？
mysql jdbc 驱动程序在 spring boot 2.3.0.RELEASE 中的正确操作是什么？
谢谢。
此配置在我的设置中运行良好。

public class Demo {
private static String url = "jdbc:oracle:thin:user/pass@localhost:1521/XEPDB1";
public static void main( String[] args ) {
System.out.print( "Testing connection to database ..." );
try {
Connection conn = DriverManager.getConnection(url);
System.out.println("OK");
System.exit(0); // Prevent hang after completion when ran by mvn
} catch (SQLException ignore) {
System.out.println("ERROR: " + ignore);
System.exit(1); // Prevent hang after completion when ran by mvn
}
}
}
What is happening with the oracle jdbc driver in spring boot 2.3.0.RELEASE ?
JDBC 驱动程序运行良好。
正如您已经在评论中了解到的那样，问题在于
a) Spring 数据 JDBC 现在需要每个数据库Dialect
b) Spring 数据 JDBC 未随 Oracle Dialect 一起提供。
修复：
如 and in https://spring.io/blog/2020/05/20/migrating-to-spring-data-jdbc-2-0所述
您现在需要提供自己的 Dialect 实现。
像这样的东西应该可以工作：
class MyOracleDialect extends AnsiDialect {
private static final LimitClause LIMIT_CLAUSE = new LimitClause() {
@Override
public String getLimit(long limit) {
return String.format("FETCH NEXT %d ROWS ONLY", limit);
}
@Override
public String getOffset(long offset) {
return String.format("OFFSET %d ROWS", offset);
}
@Override
public String getLimitOffset(long limit, long offset) {
return String.format("OFFSET %d ROWS FETCH NEXT %d ROWS ONLY", offset, limit);
}
@Override
public Position getClausePosition() {
return Position.AFTER_ORDER_BY;
}
};
@Override
public LimitClause limit() {
return LIMIT_CLAUSE;
}
}
然后您需要通过 DialectProvider 使 Dialect 可用，如引用的 Whosebug 问题中所述：
一些背景：
到目前为止，Spring 数据团队没有 运行 他们与 Oracle 数据库的集成测试。
这是因为在很长一段时间内，不清楚如何以合法的方式做到这一点，因为包括构建基础设施在内的所有代码都是开源的，而 Oracle 需要接受各种东西才能使用数据库实例或其驱动程序。
现在 Docker 图像可用于测试，JDBC 驱动程序可从 Maven Central 获得。这仍然有点棘手，因为我知道 docker 图像的当前选项允许您在许多 GB 的图像大小或大约 15 分钟的启动时间之间进行选择。
无论如何，有一个社区成员正在处理这个问题：https://jira.spring.io/browse/DATAJDBC-256
因此，我相信我们将能够在不久的将来全面支持 Oracle。
上周我遇到了完全相同的问题。
我在项目中所做的更改更简单：我只是在 pom.xml:
中将 HikariCP 依赖项替换为 tomcat-jdbc
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jdbc</artifactId>
<!-- HikariCP doesn't deals with jdbcDialect properly -->
<exclusions>
<exclusion>
<groupId>com.zaxxer</groupId>
<artifactId>HikariCP</artifactId>
</exclusion>
</exclusions>
<!-- Dependency removed -->
</dependency>
<!-- Dependency to tomcat-jdbc to deal with jdbcDialect -->
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-jdbc</artifactId>
</dependency>
<!--...-->
如果我撤消此操作，您在标题中发布的异常会再次发生。
祝你好运。
这些依赖项对我有用。

目前spring数据jdbc不支持oracle方言
您需要定义自己的方言解析器
为实现 JdbcDialectProvider.
的 Oracle Dialect 添加以下 class
import java.sql.Connection;
import java.sql.DatabaseMetaData;
import java.sql.SQLException;
import java.util.Locale;
import java.util.Optional;
import org.springframework.data.jdbc.repository.config.DialectResolver.JdbcDialectProvider;
import org.springframework.data.relational.core.dialect.AnsiDialect;
import org.springframework.data.relational.core.dialect.Dialect;
import org.springframework.jdbc.core.ConnectionCallback;
import org.springframework.jdbc.core.JdbcOperations;
public class OracleDialectResolver implements JdbcDialectProvider {
@Override
public Optional<Dialect> getDialect(JdbcOperations operations) {
return Optional.ofNullable(operations.execute((ConnectionCallback<Dialect>) OracleDialectResolver::getDialect));
}
private static Dialect getDialect(Connection connection) throws SQLException {
DatabaseMetaData metaData = connection.getMetaData();
String name = metaData.getDatabaseProductName().toLowerCase(Locale.ROOT);
if (name.contains("oracle")) {
return AnsiDialect.INSTANCE;
}
return null;
}
}
通过将文件 spring.factories 放入 class 路径的 META-INF 文件夹并添加以下行来注册您的提供商。
org.springframework.data.jdbc.repository.config.DialectResolver$JdbcDialectProvider=com.mypackage.jdbctemplate.dialect.OracleDialectResolver //fuly qualified class name of your dialect resolver class
此方言解析器解决了我与 Oracle 的问题。
@Configuration
public class SpringDataJdbcConfiguration extends AbstractJdbcConfiguration {
@Override
public Dialect jdbcDialect(NamedParameterJdbcOperations operations) {
return AnsiDialect.INSTANCE;
}
}
对已发布答案的小更新，适用于 oracle 方言
在
Build.gradle
implementation group: 'org.springframework.data', name: 'spring-data-relational', version: '2.1.1'
然后在下面创建class
import org.springframework.context.annotation.Configuration;
import org.springframework.data.jdbc.repository.config.AbstractJdbcConfiguration;
import org.springframework.data.relational.core.dialect.OracleDialect;
import org.springframework.data.relational.core.dialect.Dialect;
import org.springframework.jdbc.core.namedparam.NamedParameterJdbcOperations;
@Configuration
public class SpringDataJdbcConfiguration extends AbstractJdbcConfiguration {
@Override
public Dialect jdbcDialect(NamedParameterJdbcOperations operations) {
return OracleDialect.INSTANCE;
}
}
创建了一个新的引导项目，仅将 jdbc 和 Oracle jdbc 作为依赖项

如果我 运行 使用 spring boot 2.2.7.RELEASE 上面的代码，它工作得很好——没有例外！！
2 天后，我想到在本地主机上配置一个 mysql 数据源。同一个程序 运行 没问题（使用 spring boot 2.3.0.RELEASE）但是这次它使用了 mysql 数据源。
<dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency>
spring boot 2.3.0.RELEASE 中的 oracle jdbc 驱动程序发生了什么？
mysql jdbc 驱动程序在 spring boot 2.3.0.RELEASE 中的正确操作是什么？
谢谢。
此配置在我的设置中运行良好。

public class Demo {

System.out.println("OK");
System.exit(0); // Prevent hang after completion when ran by mvn

What is happening with the oracle jdbc driver in spring boot 2.3.0.RELEASE ?
JDBC 驱动程序运行良好。
正如您已经在评论中了解到的那样，问题在于
a) Spring 数据 JDBC 现在需要每个数据库Dialect
b) Spring 数据 JDBC 未随 Oracle Dialect 一起提供。
修复：
如Dialect 实现。
像这样的东西应该可以工作：
class MyOracleDialect extends AnsiDialect {
private static final LimitClause LIMIT_CLAUSE = new LimitClause() {
@Override
public String getLimit(long limit) {
return String.format("FETCH NEXT %d ROWS ONLY", limit);
}
@Override
public String getOffset(long offset) {
return String.format("OFFSET %d ROWS", offset);
}
@Override
public String getLimitOffset(long limit, long offset) {
return String.format("OFFSET %d ROWS FETCH NEXT %d ROWS ONLY", offset, limit);
}
@Override
public Position getClausePosition() {
return Position.AFTER_ORDER_BY;
}
};
@Override
public LimitClause limit() {
return LIMIT_CLAUSE;
}
}
然后您需要通过 DialectProvider 使 Dialect 可用，如引用的 Whosebug 问题中所述：
一些背景：
到目前为止，Spring 数据团队没有 运行 他们与 Oracle 数据库的集成测试。 这是因为在很长一段时间内，不清楚如何以合法的方式做到这一点，因为包括构建基础设施在内的所有代码都是开源的，而 Oracle 需要接受各种东西才能使用数据库实例或其驱动程序。
现在 Docker 图像可用于测试，JDBC 驱动程序可从 Maven Central 获得。这仍然有点棘手，因为我知道 docker 图像的当前选项允许您在许多 GB 的图像大小或大约 15 分钟的启动时间之间进行选择。
无论如何，有一个社区成员正在处理这个问题：https://jira.spring.io/browse/DATAJDBC-256
因此，我相信我们将能够在不久的将来全面支持 Oracle。
上周我遇到了完全相同的问题。
我在项目中所做的更改更简单：我只是在 pom.xml:
中将 HikariCP 依赖项替换为 tomcat-jdbc<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jdbc</artifactId>
<!-- HikariCP doesn't deals with jdbcDialect properly -->
<exclusions>
<exclusion>
<groupId>com.zaxxer</groupId>
<artifactId>HikariCP</artifactId>
</exclusion>
</exclusions>
<!-- Dependency removed -->
</dependency>
<!-- Dependency to tomcat-jdbc to deal with jdbcDialect -->
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-jdbc</artifactId>
</dependency>
<!--...-->
如果我撤消此操作，您在标题中发布的异常会再次发生。
祝你好运。
这些依赖项对我有用。

目前spring数据jdbc不支持oracle方言
您需要定义自己的方言解析器
为实现 JdbcDialectProvider.
import java.sql.Connection;
import java.sql.DatabaseMetaData;
import java.sql.SQLException;
import java.util.Locale;
import java.util.Optional;
import org.springframework.data.jdbc.repository.config.DialectResolver.JdbcDialectProvider;
import org.springframework.data.relational.core.dialect.AnsiDialect;
import org.springframework.data.relational.core.dialect.Dialect;
import org.springframework.jdbc.core.ConnectionCallback;
import org.springframework.jdbc.core.JdbcOperations;
public class OracleDialectResolver implements JdbcDialectProvider {
@Override
public Optional<Dialect> getDialect(JdbcOperations operations) {
return Optional.ofNullable(operations.execute((ConnectionCallback<Dialect>) OracleDialectResolver::getDialect));
}
private static Dialect getDialect(Connection connection) throws SQLException {
DatabaseMetaData metaData = connection.getMetaData();
String name = metaData.getDatabaseProductName().toLowerCase(Locale.ROOT);
if (name.contains("oracle")) {
return AnsiDialect.INSTANCE;
}
return null;
}
}
通过将文件 spring.factories 放入 class 路径的 META-INF 文件夹并添加以下行来注册您的提供商。
org.springframework.data.jdbc.repository.config.DialectResolver$JdbcDialectProvider=com.mypackage.jdbctemplate.dialect.OracleDialectResolver //fuly qualified class name of your dialect resolver class
此方言解析器解决了我与 Oracle 的问题。
@Configuration
public class SpringDataJdbcConfiguration extends AbstractJdbcConfiguration {
@Override
public Dialect jdbcDialect(NamedParameterJdbcOperations operations) {
return AnsiDialect.INSTANCE;
}
}
对已发布答案的小更新，适用于 oracle 方言 在 Build.gradle
implementation group: 'org.springframework.data', name: 'spring-data-relational', version: '2.1.1'
然后在下面创建class
import org.springframework.context.annotation.Configuration;
import org.springframework.data.jdbc.repository.config.AbstractJdbcConfiguration;
import org.springframework.data.relational.core.dialect.OracleDialect;
import org.springframework.data.relational.core.dialect.Dialect;
import org.springframework.jdbc.core.namedparam.NamedParameterJdbcOperations;
@Configuration
public class SpringDataJdbcConfiguration extends AbstractJdbcConfiguration {
@Override
public Dialect jdbcDialect(NamedParameterJdbcOperations operations) {
return OracleDialect.INSTANCE;
}
}
