Dropwizard使用jakarta而不是javax。

Question

我目前正在使用Dropwizard框架在java中开发一个webservice.对于Rest API接口，我使用的是 JAX-RS. 因为我需要用POST-Request上传文件，所以我添加了 jersey-media-multipart 到我的Gradle依赖中。然而突然间 intellij 无法解决 javax.ws.rs.* 的导入语句，但新的 jakarta.ws.rs 因此，我将接口改为 jakarta. 现在的问题是，Dropwizard显然还需要。JAX-RS 所以我在使用stacktrace时得到以下错误。

我不知道我的 build.gradle 帮助解决了我的问题，但这是我的依赖关系。

version '1.0-SNAPSHOT'

repositories {
    mavenCentral()
}

apply plugin: 'java'
apply plugin: 'application'

dependencies {
    compile 'io.dropwizard:dropwizard-core:2.0.8'
    testCompile group: 'junit', name: 'junit', version: '4.12'
    compile group: 'org.glassfish.jersey.media', name: 'jersey-media-multipart', version: '3.0.0-M1'
}

mainClassName = 'Application'

run {
    args = ['server']
}

我很无奈，在网上查了很多关于dropwizard的资料 发现他们显然应该支持雅加达，因为他们的版本是... 2.0.0. 我目前使用的是2.0.8版本，但仍然得到这个内部bug。

我使用自己的dropwizard库修复了它。dropwizard-forms 而不是jersey-media-multipart.我的新的gradle依赖关系现在是这样的。

dependencies {
    compile group: 'io.dropwizard', name: 'dropwizard-core', version: '2.0.8'
    compile 'io.dropwizard:dropwizard-forms:2.0.8'
    testCompile group: 'junit', name: 'junit', version: '4.12'
}

现在我又可以使用javax了，不需要切换到jakarta。
