實現

首先設置打包的方式，這里設置為war包。

找到pom.xml

修改打包時的項目依賴的tomcat，使其在編譯運行時使用tomcat,打包時不需要將tomcat打進包中

<!-- 打包時依賴 provided：表示編譯運行時使用tomcat,打包時不需要將tomcat打進包中--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-tomcat</artifactId><scope>provided</scope></dependency>

找到項目的啟動類，使其繼承SpringBootServletInitializer并重寫方法configure來指定項目啟動類。

package com.example.demo;import java.util.List;import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.autoconfigure.http.HttpMessageConverters; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.web.servlet.support.SpringBootServletInitializer; import org.springframework.context.annotation.Bean; import org.springframework.http.converter.HttpMessageConverter; import org.springframework.scheduling.annotation.EnableScheduling; import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;import com.alibaba.fastjson.serializer.SerializerFeature; import com.alibaba.fastjson.support.config.FastJsonConfig; import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter; @MapperScan("com.example.demo.mapper") @EnableScheduling @SpringBootApplication(scanBasePackages= {"com.example.demo.controller","com.example.demo.service","com.example.demo.interceptor","com.example.demo.handler","com.example.demo.job","com.example.demo.email"}) public class HelloSpringBootApplication extends SpringBootServletInitializer{ {@Overrideprotected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {//指明啟動類return builder.sources(HelloSpringBootApplication.class);}public static void main(String[] args) {SpringApplication.run(HelloSpringBootApplication.class, args);}}

右鍵項目--run as --Maven build

輸入命令 clean package,然后點擊Run

打包成功

來到項目的target目錄下，可以看到打包后的war包。

如果打包時出現提示：

Perhaps you are running on a JRE rather than a JDK?
