不是springboot项目怎么使用内置tomcat

不是springboot项目怎么使用内置tomcat

 

解决方法：

1.pom.xml中添加以下依赖

<properties>
  <tomcat.version>8.5.23</tomcat.version>
</properties>
<dependencies>
  <dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-core</artifactId>
    <version>${tomcat.version}</version>
  </dependency>
  <dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-jasper</artifactId>
    <version>${tomcat.version}</version>
  </dependency>
  <dependency>
    <groupId>org.apache.tomcat</groupId>
    <artifactId>tomcat-jasper</artifactId>
    <version>${tomcat.version}</version>
  </dependency>
  <dependency>
    <groupId>org.apache.tomcat</groupId>
    <artifactId>tomcat-jasper-el</artifactId>
    <version>${tomcat.version}</version>
  </dependency>
  <dependency>
    <groupId>org.apache.tomcat</groupId>
    <artifactId>tomcat-jsp-api</artifactId>
    <version>${tomcat.version}</version>
  </dependency>
</dependencies>

2.配置内置tomcat源码

package com.bx;

import org.apache.catalina.WebResourceRoot;
import org.apache.catalina.core.StandardContext;
import org.apache.catalina.startup.Tomcat;
import org.apache.catalina.webresources.DirResourceSet;
import org.apache.catalina.webresources.StandardRoot;
import java.io.File;
import java.net.URL;
public class Main {
public static final String WEB_APP_DIR = "../../src/main/webapp";
public static void main(String[] args) throws Exception {
 Tomcat tomcat = new Tomcat();
tomcat.setPort(18080);
URL url = Main.class.getClassLoader().getResource("");
StandardContext ctx = (StandardContext) tomcat.addWebapp("/", url.getFile()+WEB_APP_DIR);
tomcat.start();
tomcat.getServer().await();
}
}
