java - Gradle Jax-RS Mysql Jetty 项目无法正常工作

Question

我正在使用 gradle，我的项目构建得很好。当我使用 Jetty 部署 war 时，我看不到我的对象。

apply plugin: 'war'
apply plugin: 'eclipse'

repositories {
   mavenCentral()
}

dependencies {
    compile 'org.glassfish.jersey.media:jersey-media-json-jackson:2.16'
    compile 'org.glassfish.jersey.bundles:jaxrs-ri:2.16'
}

compileJava {
    sourceCompatibility = JavaVersion.VERSION_1_8
    targetCompatibility = JavaVersion.VERSION_1_8
}

我正在使用Gradle 构建 war java -jar jetty-runner-9.1.0.M0.jar --端口 8081 build/libs/Sample.war

并且基本上不知道从哪里获取错误。我没有看到 json 对象，但我也不知道如何使用 jax-rs 进行日志记录。预先感谢您。

Answer 1

jetty-runner 不会为基于服务器的日志记录创建日志目录。

如果您在 war 中不执行任何配置日志记录操作，那么所有 Jetty 日志都会显示在控制台上。

但是，由于您使用的是 JAX-RS，因此明智的做法是配置 JAX-RS 在您的 war 中使用的任何日志记录库来执行您需要它执行的任何操作(设置记录器级别、写入文件等)
