1. grade 添加war插件

   apply plugin: ‘war’

   War插件 添加了两个依赖配置项providedCompile 和 providedRuntime,这两个配置项分别和compile和runtime有相同的作用域，只是不将依赖打包到war文件

2. 添加依赖

注意：org.springframework.boot:spring-boot-starter-web 内置了tomcat容器，因为要部署到tomcat所以要在打包war的时候将其排除出去，所以使用了providedRuntime

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web:1.5.2.RELEASE")
    providedRuntime 'org.springframework.boot:spring-boot-starter-   tomcat:1.5.2.RELEASE'
}

1. 继承 SpringBootServletInitializer类并且重写** configure**方法

package com.test;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

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

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

1. 打包成war文件

gradle war

执行命令将在工程目录下的build/libs/目录生成war文件 将该文件放到tomcat的webapps目录下启动tomcat 搞定。。。。
