Java 在Tomcat中部署Spring Boot war

我正试图在独立的Tomcat服务器上部署我的Spring Boot应用程序（war），每次我都会遇到关于logger的错误。你对这个案子有什么想法吗

是干净的。

在pom.xml中添加对slf4j的依赖关系

可能是SLF4JAPI和jdk日志实现

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.10</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-jdk14</artifactId>
    <version>1.7.10</version>
    <scope>runtime</scope>
</dependency>

org.slf4j
在Dependency中添加sl4j api jar

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.12</version>
</dependency>

我知道有人删除了我上一篇文章，但我仍然认为这是一个类加载器问题

。。。我正在使用弹簧帽和Tomcat中战争中的弹簧靴。。。并得到相同的错误。我相信这可能是一个类加载器问题，但还没有找到正确的解决方案

避免slf4j api将使应用程序启动，而不会出现LoggerFactory NoClassDefFoundError，但hateoas类仅在编译时出现，而不是在运行时出现

    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-hateoas</artifactId>

        <exclusion>

我之前尝试添加slf4j，但它无法解决此问题。这些依赖项也有同样的错误。Tomcat的lib目录中有什么吗？有。有LIB：注释api、catalina ant、catalina ha、catalina storeconfig、catalina部落、catalina、ecj-4.4.2、el api、jasper el、jasper、jsp api、servlet api、tomcat api、tomcat coyote、tomcat dbcp、tomcat-i18n、tomcat jdbc、tomcat jni、tomcat util扫描、tomcat util、tomcat websocket、，websocket api。我尝试了您的精确设置，一切正常。这一定是你没有展示的东西，或者可能尝试重建你的战争，也许你改变了一些东西。令人惊讶的是，上次我的Tomcat是在jre 1.7下工作的。我把它改成了1.8，也把这个项目改成了1.8，现在它没有错误了。非常感谢。FWIW，我甚至试着在JRE 1.7下运行Tomcat8，也没有出现错误，所以我也不相信这是真的。不管怎样，你的问题似乎已经消失了。
