java - Spring JOOQ 生成部分失败

Question

我是 JOOQ 的新手，在生成类时遇到问题。 我有以下 Spring 配置 pom.xml

当我运行 mvn clean install -P mysql 时，它连接到数据库并在配置的 jooq 文件夹下生成一堆类。 但是在那之后我看到了很多错误，例如:

[ERROR] /Users/petervandeput/Documents/Development/test/try/jooq/com/knodeit/jooq/domain/tables/records/BookRecord.java:[76,25] cannot find symbol
[ERROR] symbol:   method get(int)

[ERROR] /Users/petervandeput/Documents/Development/test/try/jooq/com/knodeit/jooq/domain/tables/records/BookRecord.java:[210,9] cannot find symbol
[ERROR] symbol:   method set(int,java.lang.Integer)
[ERROR] location: class com.knodeit.jooq.domain.tables.records.BookRecord

[ERROR] symbol:   method set(int,java.lang.String)

有人可以提供一个 100% 工作的 pom.xml 连接到 MySql 上的模式并按其应有的方式生成吗？

Answer 1

您生成的代码以 jOOQ 3.8 为目标(例如，其中有一个 Record.get(int) 方法)。

不过，在您的依赖项中，您引用的是 jOOQ 3.7，它还没有这个方法。

您的 jOOQ 代码生成器版本和您的 jOOQ 运行时版本必须匹配。有两种解决方案:

1. 从依赖项中删除对版本 3.7.4 的引用，并改用从 Spring Boot 引用的版本
2. 明确设置版本 3.7.4 也作为您的代码生成版本(您目前忽略了它)
