MyEclipse 使用外部tomcat 调试springboot

在网上找了一些调试springboot 的文章，使用内置tomacat步骤大体都是如下步骤

1.配置插件：

<configuration>

         <jvmArguments>

           -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005

         </jvmArguments>

       </configuration>

2.启动maven命令：clean install -Ptest -X spring-boot:run

3.开调试

右击项目–>选择debug as–>Debug Configuration–>Remote Java Application

配置地址和端口号 localhost 5005

我按照此方法总是不行，所以换成了使用外部tomcat调试springboot的方案

（1）新建-》Other->搜索maven 如下图

（2）下一步

（3）输入名称

（4）点击完成

（5）修改pom.xml,添加对springboot 的引用

如下内容：

<project xmlns="http://maven.apache.org/POM/4.0.0"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

    <modelVersion>4.0.0</modelVersion>

    <groupId>com.spboot.tomcat.pomdemo</groupId>

    <artifactId>tomcattest</artifactId>

    <packaging>war</packaging>

    <version>0.0.1-SNAPSHOT</version>

    <name>tomcattest Maven Webapp</name>

    <url>http://maven.apache.org</url>

    <parent>

        <groupId>org.springframework.boot</groupId>

        <artifactId>spring-boot-starter-parent</artifactId>

        <version>2.2.7.RELEASE</version>

    </parent>

    <dependencies>

        <dependency>

            <groupId>junit</groupId>

            <artifactId>junit</artifactId>

            <scope>test</scope>

        </dependency>

        <dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-web</artifactId>

            <exclusions>

                <exclusion>

                    <groupId>org.springframework.boot</groupId>

                    <artifactId>spring-boot-starter-tomcat</artifactId>

                </exclusion>

            </exclusions>

        </dependency>

        <dependency>

            <groupId>javax.servlet</groupId>

            <artifactId>javax.servlet-api</artifactId>

            <scope>provided</scope>

        </dependency>

    </dependencies>

    <build>

        <plugins>

            <plugin>

                <groupId>org.springframework.boot</groupId>

                <artifactId>spring-boot-maven-plugin</artifactId> 

            </plugin>

        </plugins>

        <finalName>tomcattest</finalName>

    </build>

</project>

（6）创建mainApplication

如下内容

package com.tomcat.demo;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.SpringBootConfiguration;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.boot.builder.SpringApplicationBuilder;

import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.ResponseBody;

 

@SpringBootConfiguration

@Controller()

@SpringBootApplication

public class mainApplication extends SpringBootServletInitializer{

    @Override

    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {

        return builder.sources(mainApplication.class);

    }

 

    public static void main(String[] args) throws Exception {

        System.out.println("starting........................................................");

        // SpringApplication.run(bootApplication.class, args);

        SpringApplication alApplication = new SpringApplication(mainApplication.class);

        //alApplication.setBannerMode(Mode.OFF);

        alApplication.run(args);

    }

 

    @RequestMapping("/hello")

    @ResponseBody

    public String Hello() {

 

        return "1";

 

    }

}

7引入tomcat,打开官网，下载tomcat-9

8.tomcat添加到myeclipse,windows->preferences

9运行调试，选择tomcat9作为server

10访问地址http://localhost:8080/tomcattest/hello 发现断点已经进来了
