找不到jOOQ编码策略类

Question

我正在尝试添加-Pojo后缀到我生成的jOOQ pojos。

策略的实现非常简单:

package my.app.jooq.strategy
import org.jooq.codegen.DefaultGeneratorStrategy
import org.jooq.codegen.GeneratorStrategy
import org.jooq.codegen.GeneratorStrategy.Mode.POJO
import org.jooq.meta.Definition
class MyGeneratorStrategy : DefaultGeneratorStrategy() {
override fun getJavaClassName(definition: Definition, mode: GeneratorStrategy.Mode): String {
return when (mode) {
POJO -> super.getJavaClassName(definition, mode) + "Pojo"
else -> super.getJavaClassName(definition, mode)
}
}
}

但是codegen拒绝接收它。(ClassNotFoundException).

根据https://groups.google.com/g/jooq-user/c/LM5ioRHNhJw:

你必须为这个策略类创建一个单独的项目/模块，以便创建一个依赖关系图，如下所示:

1. 代码生成模块…取决于
2. 策略模块……取决于
<
3. jOOQ库/gh>

所以我……jOOQ才不管呢

PM org.jooq.tools.JooqLogger error

代码源模块是这样设置的:

plugins {
id 'nu.studer.jooq' version "${plugin_jooq}"
id 'io.spring.dependency-management'
}
dependencyManagement {
imports {
mavenBom SpringBootPlugin.BOM_COORDINATES
mavenBom "org.jetbrains.kotlin:kotlin-bom:${fw_kotlin}"
}
}
dependencies {
api "org.postgresql:postgresql"
implementation project(":backend-jooq-config")
api "org.springframework.boot:spring-boot-starter-jooq"
implementation "org.jooq:jooq-meta"
implementation "org.jooq:jooq-codegen"
jooqGenerator "org.postgresql:postgresql"
}
jooq {
version = dependencyManagement.importedProperties['jooq.version']
edition = nu.studer.gradle.jooq.JooqEdition.OSS
configurations {
myApp {
generateSchemaSourceOnCompilation = true
generationTool {
logging = org.jooq.meta.jaxb.Logging.WARN
jdbc {
driver = 'org.postgresql.Driver'
url = 'jdbc:postgresql://localhost:5432/myapp'
user = 'user'
password = 'password'
properties {
property {
key = 'PAGE_SIZE'
value = 2048
}
}
}
generator {
name = 'org.jooq.codegen.DefaultGenerator'
strategy {
name = 'my.app.jooq.strategy.MyGeneratorStrategy'
}
database {
name = 'org.jooq.meta.postgres.PostgresDatabase'
inputSchema = 'public'
includes = '.*'
excludes = ''
}
generate {
daos = true
springAnnotations = true
}
target {
directory = 'src/main/java'
packageName = 'my.app.db'
}
}
}
}
}
}

我不知道我做错了什么。

是的，策略正在编译:

find .. -name "*GeneratorStrategy*"
../backend/jooq-config/build/classes/kotlin/main/my/app/jooq/strategy/MyGeneratorStrategy.class
../backend/jooq-config/build/classes/kotlin/main/my/app/jooq/strategy/MyGeneratorStrategy$WhenMappings.class
../backend/jooq-config/src/main/kotlin/my/app/jooq/strategy/MyGeneratorStrategy.kt

如何解决这个问题?

Answer 1

修改配置

这里有一个关于如何设置第三方代码生成插件来使用自定义策略的例子:https://github.com/etiennestuder/gradle-jooq-plugin/tree/master/example/configure_custom_generator_strategy

如你所见，依赖项被指定为:

jooqGenerator project(':backend-jooq-config')

不

implementation project(':backend-jooq-config')

使用声明性配置代替

对于这种简单的情况，jOOQ还提供了一个开箱即用的配置，称为"匹配器策略"。它匹配名字并用其他东西替换它们。例如

generator {
strategy {
matchers {
tables {
table {
pojoClass {
transform = 'PASCAL'
expression = '$0_POJO'
}
}
}
}
}
}
