本文整理了Java中org.mybatis.generator.config.GeneratedKey类的一些代码示例，展示了GeneratedKey类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。GeneratedKey类的具体详情如下：
包路径：org.mybatis.generator.config.GeneratedKey
类名称：GeneratedKey

GeneratedKey介绍

[英]This class specifies that a key is auto-generated, either as an identity column (post insert), or as some other query like a sequences (pre insert).
[中]此类指定自动生成键，可以作为标识列（插入后）或其他查询（如序列（插入前）生成。

代码示例

if ("JDBC".equals(introspectedTable.getTableConfiguration().getGeneratedKey().getRuntimeSqlStatement())) {
  field.addAnnotation("@GeneratedValue(generator = \"JDBC\")");
} else {
String sql = MessageFormat.format(introspectedTable.getTableConfiguration().getGeneratedKey().getRuntimeSqlStatement(), tableName, tableName.toUpperCase());
field.addAnnotation("@GeneratedValue(strategy = GenerationType.IDENTITY, generator = \"" + sql + "\")");
