idea搭建jdk1.8.0-144源码阅读环境

  1. 新建maven 工程

  • pom文件配置

    </pluginRepository>
  </pluginRepositories>
</project>

  1. 解压jdk1.8.0_144安装目录源码src.zip至工程src/main/java目录下

  2. 修改源码位置为当前工程

  3. 引入jdk安装目录tools.jar

  4. 修改编译堆大小 700->1000

  5. 允许dbugclass

  6. 找不到sun.awt.UNIXToolkit、找不到sun.font.FontConfigManager;拷贝文件到工程目录

springboot打war配置

  1. pom配置war包插件
<build>
<finalName>${project.name}</finalName>
	<plugins>
		<plugin>
			<artifactId>maven-war-plugin</artifactId>
			<version>3.0.0</version>
		</plugin>
	</plugins>
</build>
  1. 配置打包方式
	<artifactId>xxl-job-admin</artifactId>
	<packaging>war</packaging>
  1. 修改springboot启动类，继承 SpringBootServletInitializer，重写 configure方法
package com.xxl.job.admin;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

/**
 * @author xuxueli 2018-10-28 00:38:13
 */
@SpringBootApplication
public class XxlJobAdminApplication extends SpringBootServletInitializer {

	public static void main(String[] args) {
        SpringApplication.run(XxlJobAdminApplication.class, args);
	}

	@Override
	protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
		return builder.sources(XxlJobAdminApplication.class);
	}
}
  1. 打包
mvn clean package -Dpackage.skip.test
  1. 注意
    1. 打jar包，配置成jar
    2. 打war包，用工程目录访问资源；application.properties如下配置将失效，使用tomcat配置
server.port=8080
server.servlet.context-path=/xxl-job-admin

3. main方法和tomcat都可以跑起来
4. 打jar和war具体看线上环境和运维部署方式
