我知道这是一个老问题，但是我发布了答案，因为它可能对其他人有用。
我不得不面对同样的需求，这很难实现，因此在这里您可以找到实现从
enums架构生成枚举的代码。
该代码是用groovy实现的，但是对于Java来说却非常相似。
首先也是 非常重要的一点 ，我必须为我的枚举生成器创建一个单独的项目，因为它将作为要使用它的项目的依赖项。这是 必需的，
因为生成代码的项目必须在编译时运行枚举生成器，因此实现此目的的方法是将枚举生成器添加为依赖项。
枚举生成器项目依赖项
package com.ctg.jooqgenerator.jooqimport org.jooq.pregen.JavaGeneratorimport org.jooq.pregen.JavaWriterimport org.jooq.meta.Databaseimport org.jooq.meta.SchemaDefinitionimport org.jooq.meta.TableDefinitionimport org.slf4j.Loggerimport org.slf4j.LoggerFactoryimport java.sql.ResultSetclass EnumGenerator extends JavaGenerator { private static final String ENUMS_SCHEMA = "enums" private static final Logger log = LoggerFactory.getLogger(EnumGenerator.class) @Override void generateSchema(SchemaDefinition schema) { // Apply custom logic only for `enums` schema. Others schema has regular generation if (schema.name != ENUMS_SCHEMA) { super.generateSchema(schema) return } log.info("Generating enums") log.info("----------------------------------------------------------") Database db = schema.database db.getTables(schema).each { TableDefinition table -> // Prepare enum name from snake_case to CamelCase String enumName = table.name.replaceAll('_([a-z])') { it[1].capitalize() }.capitalize() JavaWriter out = newJavaWriter(new File(getFile(schema).getParentFile(), "${enumName}.java")) log.info("Generating enum: {}.java [input={}, output={}]", enumName, table.name, enumName) printPackage(out, schema) out.println("public enum $enumName {") ResultSet rs = db.connection.prepareStatement("SELECT * FROM ${schema}."${table.name}"").executeQuery() while (rs.next()) { String name = rs.getString('name'), description = rs.getString('description'), s = rs.isLast() ? ";" : "," // Generate enum entry out.tab(1).println("$name("$description")$s") } out.println(""" | private final String description; | | private $enumName(String description) { | this.description = description; | } |} """.stripMargin()) closeJavaWriter(out) } log.info("----------------------------------------------------------") super.generateSchema(schema) }}具有枚举表的数据库
将转换为枚举的表如下所示：
-- Table name `account_role` will be translated into `AccountRole`CREATE TABLE enums.account_role ( "name" varchar(100) NOT NULL, description varchar(255) NOT NULL, ConSTRAINT account_role_name_key UNIQUE (name));-- Table entries will be translated into enum entriesINSERT INTO enums.account_role ("name",description) VALUES ('BILLING','Role for contact/address that will be a Billing contact/address'),('PAYMENT','Role for contact/address that will be a Payment contact/address'),('SERVICE','Role for contact/address that will be a Service contact/address'),('SOLD_TO','Role for contact/address that will be a SoldTo contact/address');此数据定义将导致以下自动生成的枚举AccountRole.java：
package com.congerotechnology.ctgcommon.jooq.enums;public enum AccountRole { BILLING("Role for contact/address that will be a Billing contact/address"), PAYMENT("Role for contact/address that will be a Payment contact/address"), SERVICE("Role for contact/address that will be a Service contact/address"), SOLD_TO("Role for contact/address that will be a SoldTo contact/address"); private final String description; private AccountRole(String description) { this.description = description; }}主要项目
然后在将使用此枚举生成器的主项目上，我在上设置了以下maven代码
