是使用傳統(tǒng)war包的方式進(jìn)行熱加載.

• IDE: IDEA
• 框架: SpringBoot
• 構(gòu)建工具: maven

步驟:

1. 修改POM.XML 文件
   修改SpringBoot的打包方式,打包為war包 <packaging>war</packaging>
   

   package
   
   修改spring-boot-starter-tomcat新增標(biāo)簽 <scope>provided</scope>
   
   provided

2. 實(shí)現(xiàn)SpringBootServletInitializer類

package com.wanda.yima.puccenter;

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

public class PucCenterServletInitializer extends SpringBootServletInitializer {

  @Override
  protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
      return application.sources(Application.class);
  }

}

3. 開啟IDEA 自動(dòng)編譯

4. 修改 registry
   Mac電腦: shift + option + command + / 開啟.
   windows: shift + alt + win + / 開啟.

   
   
   registry
   
   

   勾選compiler.automake.allow.when.app.running

5. 添加tomcat服務(wù)器
   下載Tomcat服務(wù)器后,打開Run Configurations

注意點(diǎn):

• 配置Tomcat服務(wù)器后,On 'Update' action 要選擇'Update Classes and Resources'
  On Frame deactivation 要選'Update Classes and Resources'
• Deployment中,配置war包時(shí),要選擇帶exploded的war包.

6. 啟動(dòng)
   以debug模式啟動(dòng),啟動(dòng)后,修改后,只需點(diǎn)擊update則可以進(jìn)行熱加載
