嘿，请确保对pom.xml进行此更改
<packaging>war</packaging>
在“依赖项”部分中，请确保指示提供了tomcat，因此您不需要嵌入的tomcat插件。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
这就是整个pom.xml

而且Application类应该像这样
应用程序
package com.example;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
@SpringBootApplication
public class Application extends SpringBootServletInitializer {
/**
* Used when run as JAR
*/
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
/**
* Used when run as WAR
*/
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(Application.class);
}
}
您可以添加一个控制器来测试MyController.java
package com.example;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class MyController {
@RequestMapping("/hi")
public @ResponseBody String hiThere(){
return "hello world!";
}
}
然后，您可以在tomcat 8版本中运行项目并像这样访问控制器
http：// localhost：8080 / demo / hi
如果由于某种原因您无法将项目添加到tomcat，请右键单击该项目，然后转到“构建路径”->“配置构建路径”->“ Project Faces”
确保仅选择这3个
动态网络模块3.1 Java 1.8 Javascript 1.0
SpringBootServletInitializer并覆盖了它的configure方法吗？
