如何调整 Spring Data JDBC 的 NamingStrategy

Question

我如何调整 Spring Data JDBCNamingStrategy使其行为像 Hibernate\xc2\xb4s PhysicalNamingStrategy？
\n我有以下实体：

\n\n

/**\n * Campus domain model class.\n * Handles information about campus.\n *\n * @author thomas.lang@th-deg.de\n */\n@Data\n@AllArgsConstructor(access = AccessLevel.PRIVATE, onConstructor = @__(@PersistenceConstructor))\npublic class Campus {\n\n    private final @Id\n    @Wither\n    long campusId;\n\n    @NotNull\n    @Size(min = 3)\n    private String campusName;\n\n    /**\n     * Creates a new campus.\n     *\n     * @param campusName\n     */\n    public Campus(@NonNull String campusName) {\n        this.campusId = 0;\n        Assert.hasLength(campusName, "A valid value has to be provided for Campus!");\n        this.campusName = campusName;\n    }\n\n}\n

\n\n

当我希望 JDBC 持久化测试记录时，它会生成以下 sql：
\n[INSERT INTO campus (campus_name) VALUES (?)]

\n\n

我现有的数据库有一列名为campusname

\n\n

我在这里阅读了文档https://docs.spring.io/spring-data/jdbc/docs/1.0.2.RELEASE/reference/html/#jdbc.entity-persistence.naming-strategy我可以调整命名策略，但我不\xc2\xb4t 知道如何:)

在您的应用程序上下文中创建一个类型的 bean NamingStrategy，并根据您的喜好实现其方法。

您需要重写的方法是getColumnName(RelationalPersistentProperty)
