标签： java spring eclipse maven

我创建了一个vanilla Spring Boot App（1.5.9.RELEASE）但是当我Run As -> Spring Boot App（在Eclipse Oxygen中）我得到了

SLF4J: Defaulting to no-operation (NOP) logger implementation

应用 

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class CourseApiApp {

    public static void main(String[] args) 
    {
        SpringApplication.run(CourseApiApp.class, args);
    }
}

备注

我也试过mvn clean package - ＆gt; java -jar target/boot-demo.jar给了我

9 个答案:

答案 0 :(得分：5)

扩展Mark Bramnik回答，看起来你没有回溯，这很奇怪，因为spring-boot-starter-web依赖于spring-boot-starter-logging。只需尝试将spring-boot-starter-logging添加到您的POM文件

答案 1 :(得分：3)

看起来你正在尝试使用logback日志记录实现，但在类路径中没有logback jar：

请尝试添加这样的东西（取决于Spring Boot版本，可以有另一个实际版本的logback依赖）

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.1.11</version>
</dependency>

然后您可能想要配置记录器，追加器等。有关登录spring boot的更多信息，请阅读a chapter from official Spring Boot documentation。

答案 2 :(得分：1)

Spring Boot应用程序期望logback经典依赖关系。由于无法在类路径中找到logback-classic jar，因此抛出错误 造成原因：java.lang.NoClassDefFoundError：ch / qos / logback / classic / turbo / TurboFilter。

添加以下依赖项后，应用程序开始运行，没有任何问题。

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.1.11</version>
</dependency

答案 3 :(得分：0)

显然我在类路径中有一个破损的jar，从.m2中删除所有内容并更新它后都有效。

答案 4 :(得分：0)

从maven repo中删除所有内容并在eclipse中更新项目对我有用。

答案 5 :(得分：0)

    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-core</artifactId>
        <!-- <version>${logback.version}</version> -->
    </dependency>

在我的情况下，添加此注销将明确解决该问题。

答案 6 :(得分：0)

这对我有用，尽管不是很聪明：从.m2文件夹中删除ch文件夹，然后从Eclipse中执行Run>'Maven install'。

答案 7 :(得分：0)

对我们来说java.lang.ClassNotFoundException: ch.qos.logback.classic.joran.JoranConfigurator意味着已经排除了spring-boot-starter-logging，但是显然需要添加spring-boot-starter-log4j2来替换它或类似的东西。

答案 8 :(得分：-1)

在.m2目录中删除ch文件夹并在eclipse项目中更新maven项目有助于解决此问题。
