篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了springboot项目打成war后部署到tomcat，Tomcat启动时spring boot未加载相关的知识，希望对你有一定的参考价值。

参考技术A maven打成war包后部署Tomcat后，启动页面没有看到spring boot加载的信息，即控制台没有打印出那个大大的spring boot 字符串，这是spring boot没有被容器加载，修改方法如下：

@SpringBootApplication

public class RestApplication extends SpringBootServletInitializer

@Override

protected SpringApplicationBuilder configure(SpringApplicationBuilder builder)

return builder.sources(RestApplication.class);

public static void main(String[] args)

SpringApplication.run(RestApplication.class, args);

就是让启动类继承SpringBootServletInitializer，并重写configure方法，然后再打war包部署，就能成功加载spring boot了，项目能够正常访问。

spring boot项目打成war包部署到tomcat

实例项目共三个模块：

package

其中package依赖m1和m2，将m1和m2编译生成的jar包一起打成一个war包。

springboot项目打成war包部署到tomcat时需要改变启动方式，否则运行tomcat时war包只会解压，但是加载不了

package的Application.java文件内容：

 1 import org.springframework.boot.SpringApplication;
 2 import org.springframework.boot.autoconfigure.SpringBootApplication;
 3 import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
 4 import org.springframework.boot.builder.SpringApplicationBuilder;

 7 @SpringBootApplication
 8 public class Application extends SpringBootServletInitializer {
 9     
10     public static void main(String[] args) {
11         
12         SpringApplication.run(Application.class, args);
13     }
14     
15     @Override
16       protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
17         return builder.sources(Application.class);
18       }
