问题描述

在百度搜索关键词,搜索到了 Stack Overflow 有相关问题

spring-configuration-metadata.json file is not generated in IntelliJ Idea for Kotlin @ConfigurationProperties class

原文链接:

按照里面的方法试了一下,失败了,然后继续百度,在spring-boot的官方文档中找到了相关线索, 直达链接:

https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-kotlin.html#boot-features-kotlin-configuration-properties

在spring官方文档中找到了kotlin的官方示例,链接地址:

https://kotlinlang.org/docs/reference/kapt.html#using-in-maven

下面是我参考上面的文档所得出来的可用方案

解决方案

一、添加插件

在pom文件中添加插件,没有写版本号是因为项目继承了spring-boot-starter-parent

<plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><configuration><proc>none</proc><source>${java.version}</source><target>${java.version}</target></configuration><executions><!-- Replacing default-compile as it is treated specially by maven --><execution><id>default-compile</id><phase>none</phase></execution><!-- Replacing default-testCompile as it is treated specially by maven --><execution><id>default-testCompile</id><phase>none</phase></execution><execution><id>java-compile</id><phase>compile</phase><goals><goal>compile</goal></goals></execution><execution><id>java-test-compile</id><phase>test-compile</phase><goals><goal>testCompile</goal></goals></execution></executions></plugin><plugin><artifactId>kotlin-maven-plugin</artifactId><groupId>org.jetbrains.kotlin</groupId><configuration><args><arg>-Xjsr305=strict</arg></args><compilerPlugins><plugin>spring</plugin></compilerPlugins><jvmTarget>${java.version}</jvmTarget></configuration><executions><execution><id>kapt</id><goals><goal>kapt</goal></goals><configuration><sourceDirs><sourceDir>src/main/kotlin</sourceDir><sourceDir>src/main/java</sourceDir></sourceDirs><annotationProcessorPaths><!-- Specify your annotation processors here. --><annotationProcessorPath><groupId>org.springframework.boot</groupId><artifactId>spring-boot-configuration-processor</artifactId><version>${spring.boot.version}</version></annotationProcessorPath></annotationProcessorPaths></configuration></execution><execution><id>compile</id><phase>compile</phase><goals><goal>compile</goal></goals></execution><execution><id>test-compile</id><phase>test-compile</phase><goals><goal>test-compile</goal></goals></execution></executions><dependencies><dependency><groupId>org.jetbrains.kotlin</groupId><artifactId>kotlin-maven-allopen</artifactId><version>1.2.20</version></dependency></dependencies></plugin>
</plugins>

二、使用插件生成

我之前也是使用了同样的插件,但是始终生成不出来文件,直到看了kotlin官方文档我才发现有这么一句话

文字的意思是:

"请注意，kapt仍然不支持IntelliJ IDEA自己的构建系统。当你想要重新运行注释处理器时，可以从“Maven Projects”工具栏启动构建。"

很是坑爹啊,你也不标红也不加粗是想怎样啊

好了,那就按照他说的做吧, 双击下面的插件按钮就可以生产spring-configuration-metadata.json文件了
