Tomcat上的Spring启动war文件部署

Question

我使用Spring Boot 1.2.4.RELEASE和gs-rest-service源文件.我有:

127.0.0.1 - - [18/Jun/2015:09:59:25 +0300] "GET /gs-rest-service-0.1.0/ HTTP/1.1" 404 1021

Tomcat日志中没有其他例外.

我已阅读相关问题,但我的测试没有运行. Spring Boot War部署到Tomcat

我已经阅读了howto-create-a-deployable-war和Packaging可执行jar和war文件.

也许我想念一些东西.

2.Application.java

package hello;

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

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

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

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

文件Greeting.java和GreetingController.java不会更改.

Answer 1

刚试过这个,可以重现完全相同的行为.

听起来很傻,很可能你是在Java 1.7 JRE(推测)下运行你的外部tomcat,而你的代码是针对1.8编译的(我们从你的pom中知道这个).

奇怪的是,没有错误,应用程序出现在经理应用程序中,但是当您尝试访问它时,您会得到404.

确认这一点的一种方法是查看tomcat日志输出.你看到Spring Boot横幅吗？可能不是.
