我正在嘗試為-Pojo我生成的 jOOQ pojos 添加一個后綴。
策略實施很簡單：
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 codegen 只是拒絕接受它。( ClassNotFoundException)。
根據https://groups.google.com/g/jooq-user/c/LM5ioRHNhJw：
您必須僅為該策略類創建一個單獨的專案/模塊，以便創建一個依賴關系圖，如下所示：
- 代碼生成模塊...取決于
- 策略模塊...取決于
- jOOQ 庫
所以我做了... jOOQ 不在乎。

下面是 codegen 模塊的設定方式：
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'
}
}
}
}
}
}
我看不出我做錯了什么。
是的，正在編譯該策略：
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
我該如何解決這個問題？
uj5u.com熱心網友回復：
修復你的配置
這里有一個關于如何設定此第三方代碼生成插件以使用自定義策略的示例： https ://github.com/etiennestuder/gradle-jooq-plugin/tree/master/example/configure_custom_generator_strategy
如您所見，依賴項指定為：
jooqGenerator project(':backend-jooq-config')
不是
implementation project(':backend-jooq-config')
改為使用宣告性配置
對于這種簡單的情況，jOOQ 還提供了一個開箱即用的配置，稱為“匹配器策略”，它匹配名稱并用其他東西替換它們。例如
generator {
strategy {
matchers {
tables {
table {
pojoClass {
transform = 'PASCAL'
expression = '\$0_POJO'
}
}
}
}
}
}
