Failed to start component [StandardEngine[Tomcat].StandardHost[localhost].TomcatEmbeddedContext[]]
提问by Betafish
I am trying to build a SpringBoot application.
我正在尝试构建一个 SpringBoot 应用程序。
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
@SpringBootApplication
public class App {
@SuppressWarnings("unused")
public static void main(String[] args) throws Exception {
ApplicationContext ctx = SpringApplication.run(App.class, args);
}
}
But, when I try to run the app, it throws me the below error:
但是，当我尝试运行该应用程序时，它会引发以下错误：

As mentioned in some SOposts, I tried removing (Jersey), adding (embedded tomcat) dependencies. But the error seems not to be having an effect on the changes.

This works completely fine. Any pointers as to why this is the case?
这完全正常。关于为什么会这样的任何指示？

Looks like you have an incompatible version of Servlet API in ur classpath. This could have been as a dependencies to Jersey jars. Try pulling jersey starter from Spring boot starters.
看起来您的类路径中有一个不兼容的 Servlet API 版本。这可能是对 Jersey jars 的依赖。尝试从 Spring boot starters 中拉出 jersey starter。
org.springframework.boot : spring-boot-starter-jersey
This will bring the right version into your classpath.
这会将正确的版本带入您的类路径。

I had the same issue, After commenting out the below it was fixed. One of the follwoing dependency was the culprit.
我有同样的问题，在注释掉下面之后它被修复了。以下依赖之一是罪魁祸首。
<!-- dependency>

<version>0.12.0-RELEASE</version>
</dependency-->
<!-- dependency>
<groupId>com.fasterxml.Hymanson.core</groupId>

My guess is you have to use the default ServletInitializerclass that is provided within the Spring Boot Project templateof Eclipse.
我的猜测是您必须使用Eclipse 中ServletInitializer提供的默认类Spring Boot Project template。
//SpringBootApplication.java
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SpringBootApplication {
public static void main(String[] args) {
SpringApplication.run(SpringBootApplication.class, args);
}
}
//ServletInitializer.java
public class ServletInitializer extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SpringBootApplication.class);
}
}
If you are not using ServletInitializerclass as specified in Spring Boot Starter Projecttemplate, try to extend SpringBootServletInitializerfrom your App class
如果您没有使用模板中ServletInitializer指定的类Spring Boot Starter Project，请尝试SpringBootServletInitializer从您的 App 类扩展
public class App extends SpringBootServletInitializer

For me, upgrading javax.servlet-api to 4.0.1 did the trick:
对我来说，将 javax.servlet-api 升级到 4.0.1 成功了：
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>4.0.1</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>4.0.1</version>
</dependency>
